Timewave ANC 4- Testing continues

September 27, 2009

If you refer back to yesterdays post you know that I am now “playing” I mean testing out a very lightly used Timewave ANC 4 Noise Cancelling Device.

anc-4FLOAT

Timewave ANC-4 “RF Noise Canceller”

And so far I am pleased but puzzled with the results found…  Last night I tested it out using my FT847 and LDG Z100 Autotuner.  I was using  a 50 foot dipole (25 feet per side) as a non resonant recieving antenna to pick up the noise that the device is supposed to phase shift to lower my actual noise level.

ft847

Z100F

It brought my noise on 80m which is the only band I really have troubles on from a S9 + down to around S5 which was excellent.  I should mention that I also find it lowers signals as well as noise but it lowers the noise more and its much easier to listen to a S5 signal with a low noise level than a S9 signal with a high noise level so I have to say it works.

Today (Sunday) as I am experimenting decided to see it the ANC 4 would work with my FT 897D which I use sometimes in the field and also as my backup HF rig here in the shack…

ft897dNow all I did was swap out the 847 and Deep Cycle RV Battery out for the FT897 and 30ah battery pack.  The tuner remained the same, the antenna and grounding system remained the same…  All I did was switch out the radio and change batteries…

The results were not promising….  What was a S9 +20 noise level before was now a S9 +30 noise level and the ANC 4 would not bring the noise level down below a S9 +20….

Now I am at a loss as to what the HECK is going on but I guess more testing is needed.  I do remember seeing something in the EHAM Reviews about having to put up a 2nd resonant dipole up to use to supple the signal to shift out of phase in extreme cases so I guess later this week I will put up my multi band vertical and try using that as the receiveing antenna….  If this above statement has really cofused you just head over to the Timewave website (the link is just below the picture of the device) and read the PDF Manual file as they explain it much better than I could…

So I still stand by my earlier comments that “IT WORKS” but now I will add the disclaimer that it work(ed) with my FT 847.  I will also say that much more testing is needed before I can say it works with all my HF rigs…

Just in case you have used one of these devices in the past and could share a secret on how to get it to function better please feel free to leave me a comment on this post… I wont have much time till later in the week due to a couple of other commitments along with a forcast of rain to try changing much so it look like this will get the time it deserves late this week…  The ARES Ontario SET exercise is this Saturday so it better be done by then….

More as I find the time to do the changes….

Testing out a new toy…

September 26, 2009

Today I was lucky enough to borrow the following neat toy:

anc-4FLOAT

Timewave ANC-4 “RF Noise Canceller”

Initial reports are that “it works”….

It has lowered my noise level down from the S9 + level that I have been b!tching about for so long down to a S5 on 80m.  That is a good thing….  I was able to check into the ONTARS Net on 3.755 and actually hear the Net Control Station who was in the Niagara Falls/St Catherine area just above the noise level.  Normally this would not happen as with the ANC4 turned off my noise level returned to just above S9.

Instead of the two supplied antennas I am using  a 50 foot non resonant dipole in my back yard at 5 feet above ground to supply the signal to put out of phase. This is one of those things that if you follow the link above you will find the manual and once you read the manual you will then understand what I am talking about in this paragraph.

Needless to say IT DOES WORK….  How good it works will be decided after I have had more time to test things out but….IT DOES WORK…

More on this topic as I learn what I am doing with it and how to properly operate it.  Translation ….  Once I RTFM…

Timewave ANC4 **MAY NOT** be needed

May 26, 2009

Yup you read it right….

Yesterday I finally got the weighted line over the tree branch in the front yard and I was able to extend the Inverted L a little higher up and change its direction slightly.  At the same time I was forced (by the length of the driven element) to move the 4:1 Balun about 8 feet away and raise it by 6 feet.

The end result of this is now my noise level as I type this right now is S9 (down from +30) on 80m and it goes down from there.  Outgoing signal reports range from S9 to “30 over” so nothing seems to change much there…

Now this is not the end all of the situation but its a start…  Last night on the 3730 Group I was able to check in and the local noise had dropped to a S7 and for the first time in memory I could hear every station the NCS could hear and he was (according to QRZ.com) 60kms south of me.

I have one minor problem…  the driven element of the Inverted L as it goes over my roof is hooked something thats up there.  Over the next few days I will have to take the tension off the line and try raising it up using one of my portable masts in the hope of being able to flip it over whatever is causing the obstruction.  I got it over one obstruction yesterday but did not have the time to try for the 2nd…

Daytime use of 80 is not the best but the evenings are coming along nicely…

At the same time I was doing this work I managed to raise my 6m dipole about 5 feet higher and aim it east west.  With here being no conditions and no locals on so far all I can report is that the SWR is good.  Hopefully I will be able to test things out in a few days…

It was a great conclusion to yesterday….

Knew I forgot something….

May 22, 2009

In Ottawa yesterday the weather was fantastic…  I managed to get some non-radio releated yardwork done…. A great afternoon walk… an early BBQ with Erika (daughter) and then an interesting evening watching the television…  I did try to modify my antenna again to cut down on the noise with no success and I was able to hear one station check into the Ontario Phone Net so I was able to get relayed in to the NCS…

I am starting really to get discouraged with my lack of success with the high noise level on the 80m band.  After adding grounds, and overall swapping out of equipment trying different feed lines and antennas with different radios and different tuners all with the same results…

Last nights attempts were really an issue when I check into the OPN and get a signal report of  “30 over” which is a huge increase from my old S9 signals and can’t hear anything less than a “20 over” signal due to my extremely high noise levels.  And before you ask I have tried going back to the old ways and antenna styles but the noise remains the same…

I believe it to be (as stated MANY, MANY, MANY, MANY times in the past) a problem with one of my many neighbors running some sort of electrical device that throws out noise close to the 80m band or its a leaky transformer…

Right now the noise is S7 on 160m,   S9 +20 on 80m,  S8 on 40m,   S5 on 30mS4 on 20m S2 on 17m,  S2 on 15m,  S1 on 12m and a big ZERO on 10m.

So as you can see I was busy yesterday….   Got lots accomplished but I also did forget to post yesterdays entry in the BLOG…  I also forgot to attend the OVMRC Meeting so I really was distracted…

Anyhow…  There will be a posting later today on the weekends events, the weather is looking good….  and the antenna work I planned to get done this week was put on the backburner by my constant attempts to cure the high noise levels…   I don’t think there is much I can do there till HYDRO comes in to do the anticipated repairs/upgrades in my neighborhood…

Till this afternoon or early evening….

Its Tuesday and the weeks plans are…

May 19, 2009

Good Tuesday Morning Group,

This week now that the rush of the Long Weekend is over and hopefully the temps are going to rise and the WX is going to improve, allowing the following things have to be done…

Somehow I have to casually head into my front yard and try and get a weighted line over a tree branch thats approx 10 feet above roof height.  This is the planned support for the Inverted L antenna for HF .

Once I get the antenna raised up I can concentrate in getting the noise level lowered as so far its an exercise in frustration.  So far the best results have been in wrapping the balun with strips of tin foil which attenuates some of the static level that plagues my location.  Its trial and error at the best but its better than nothing…

The trick is to put enough tin foil out that it just slightly lowers the noise level.  Too much and you attenuate the incoming signals as well.  Too little and the static overpowers the signals coming in…

Next antenna project is to get my dual band beam up and aimed.  I am thinking of taking the dual band J Pole down and replacing it with the beam.  Recently there has been a few times that I have needed to talk on 2m just slightly out of my range and the beam would of helped…  Last time I needed the beam for the Balloon Flight of VE3REX-11 and VE3LCA-11 as they headed east and this time its a two day cycle tour (Rideau Lakes Cycle Tour)  thats heading from Ottawa to Kingston on the Saturday and returning on the Sunday.  I need to access the Lavant Repeater for this one….  and the beam will be needed…

On a radio related topic for a minute…  I also need to start riding my bike a bit more for both my health and also it would be nice to go out with the FT 817 and the W3EDP and play from some new locations…  Bouncing back to my static levels at home for a minute…The tin foil is trial and error…  Too much and I can’t hear anything….  Too Little and I can’t hear anything….  It might be easier to set up in the park and if the band is open I know I will hear things…  I think my knees would be happier if I were to get some kms under my belt and get some exercise and drop a few pounds.  For that matter I think my doctor would be thinking the same things as well…

I’m not thinking of setting up to operate bike mobile other than the handheld attached to the bracket on the handlebars but more just using the bike as a method of transportation to get me out there to play.

Failing that I gotta find some way to shed the pounds ….

No real upcoming events to worry about this week….  The OVMRC Monthly Meeting will be this Thursday and other than the usual evenings VHF nets not much is coming up…  We do have field day next month along with the RAC Canada Day Contest  and before Field Day comes the ARRL VHF Contest.

In the past, for the VHF Contest, I have taken the FT 857 and the beams out to a portable location and set up to play for a few hours.  This year I’m thinking of trying to get the antennas set up at home and go from here.  Operating from home would allow me to get more of the equipment ready for the RAC Canada Day Contest which would be my favourite of the three events.

But right now all 3 contests/events are a month away so theres a lot of plans to change before then…

For now enjoy your week and check back soon…

Victoria Day Long Weekend Plans

May 15, 2009

Hi Group,

This weekend officially marks the beginning of summer here in VE/VA/VY/VO Land as this weekend is the “Third Weekend in May” which is the Queen Victoria Long Weekend Celebration.

I think its a nice touch that they actually have a holiday to honour Victor Alpha 3 Queen Victoria but to be honest I believe they are actually talking about the other Queen Victoria…

This weekend is also the normal first opening weekend for Campgrounds and Cottages which also have the time known as the May “24”  Long  Weekend.

For the benefit of my non-Canadian Readers the reason its called the “May “24”  Long  Weekend.” is fairly simple…  The weekend occurs in May, the Monday is a STAT Holiday which honours Queen Victoria  and 24 is the number of beers that are sold in a case…

From my earlier years I can remember heading out to the trailer (it was a tent trailer near Smith Falls then) for the 2nd weekend in May to make sure all was set up in anticipation of the “Official Opening of our camping summer” the next weekend.  The Propane tanks would be filled, the yard raked and all the necessary work would be done so that when we arrived on the following Friday late afternoon with the family  we could get unpacked and then sit back relax, have a BBQ Supper, a few beers, then we would sit by the campfire and re acquaint ourselves with our camping neighbors (with the help of a few more beers…)who we had not seen since the official closing of the campground normally done the Canadian Thanksgiving weekend which is in mid October…

This year my trailer still sits in Cornwall and I have not been able to even visit it for a day to see if it survived the winter…  Hopefully before June….

This weekend I plan to do the last of the HF Antenna work…  Thats right the “Last” of the HF Antenna work….  I have finally reached the point where I can do no more with my circumstances.  In my attempts to get away from the high noise level I have (a) changed styles of antenna for a vertical wire to an inverted “L”, (b) grounded the transmitter and tuner to a cold water pipe, (c) grounded the coax, mast and antenna mount to a grounding block which is attached to a 5 foot ground rod pounded into the ground, (d) re installed and re designed the counterpoise/radial system and stretched them in the best configuration my yard will allow,   (e) tried no balun and connected direct to antenna, (f) tried a 1:1 balun with no luck,  (g) tried a 4:1 balun (now have 160m but still noisy) with no real change, (h) Have “swapped out 3 different autotuners, 4 different HF Radios, and changed feedlines.

Yesterday I raised the “Apex of the inverted L approx 10 feet higher and  there was no real change in the noise level.  This weekend I will raise the end of the antenna approx the same height and thats all I can do.

Every one of these changes has improved my outgoing signals and now people are using the term ” Armchair copy” to describe my signals on all the bands.  Now thats a term that normally does not get used when anyone describes my signals…

But on 80m the signal coming in is far from good copy even…  My noise level on a “Good Day” would be close to S7.  On an average day it would be S9 and S9+20 on a bad day…  The noise seems to be close to 80m with levels being S5 to S7 on 160m and 40m.  20m to 10m is much quieter and if you are a regular reader of the blog you know the interference is not from this house as I have cut the power (flipped off every breaker) and sat in the dark and the noise level has not changed…

So as previously mentioned this weekend I raise the end of the Inverted “L” and if that does not work I can’t think of anything else to do…  I’m fresh out of ideas so when that happens….  I either tear it all down and take up a new hobby or I just continue on with the hobby I love and just don’t operate as much on 80m..

I did say I wanted to DX a bit more and I do have a 20m vertical I built a while ago so perhaps its time to look at that aspect of the hobby for a while…

On to other stuff….  Last night I had the chance to cover a few different modes of amateur radio communications.  I was sitting in the shack trying to listen the the 3730 group when I got an APRS Text Message from VE3XGD who asked me to meet him on Repeater VE3RIX.  I switched over and we started to chat.  Gord was heading to his cottage located near Golden Lake and  I decided to keep him company for a while.  We ran on VE3RIX till we ran out of repeater and then Gord suggested that I echolink over to VE3STP so we could continue the conversation.  I tried to connect via RF using RIX and its echolink connection but no luck.  I was able to ECHOLINK in to VE3STP however using my laptop and so we continued our conversation from my laptop to the internet to ve3stp to gords mobile…   The system worked great and I was able to continue the conversation from Arnprior Ontario which was where we lost repeater VE3RIX right through to Gord pulling into his laneway at the cottage.  It was an enjoyable way to spend an hour…

Back to the weekend for a while…  If you remember a few days ago I posted about the Cable TV vs RF issues.  I made some comments that the local programming will be threatened if there is no changes to the way the cable companies operate.  It seems this is coming a bit more to a head.  If you follow THIS LINK you will see what I am talking about…and was talking about…  I will remind you about a statment I made in my blog on May 13 which said:

< So lets get back to the channel list…  The Global Network is having financial issues and so is A Channel.  I can’t remember the last time I saw local programming on CBC Ottawa but CTV Ottawa does a fair job squeezing in some local items and they have an excellent local news…  However if you think of it…  If the A Channel folds then we will only have one source of local programming in Ottawa…

Whats my point here….  With the recent economic crisis thats suddenly become part of our lives sooner or later people are going to have to make cuts to get by…

If the local broadcasters are off the air, if stations close then what will people watch who can not afford the luxury of Cable TV or Satellite TV?  What about local news?

Now I have been told that the Cable Companies pay the speciality networks for their programming.  That means that if you watch a hockey game on TSN or anything on TSN the cable distributer pays TSN.  However if you watch the same hockey game on CBC the feed is free to the cable companies.  However the last time I checked my bill we do get charged for the “Basic Cable Package” which has just a little bit more than I can get with the outdoor antenna.

I remind you of my comments earlier in this posting…

“The Broadcasters would like to be able to charge the cable companies for re transmitting their signals which only seems fair to me as the cable companies charge for what they re broadcast.”

Now to be honest this is not at the rant level yet…  This is just putting an example of what could happen…  I have nothing against my cable provider who does provide excellent service…  I do wonder why they are charging me for something they get for free and I also wonder if the local channels (like A Channel) folds will I get a discount as there is less to watch…  >

Anyway after refreshing your memory I’ll mention that the Local CTV station in Ottawa and the A Channel station are both holding open houses NEXT (Thanks Jamie) weekend so we can see what we are really in a good position to lose.  The stations will most likely be still transmitting but it will be the same network feed we see with no local content…  Remember 20 years ago when if you listened to the radio you heard a local DJ even on the overnite slot??  Last year when I was driving south on Interstate 81 I was able to follow the same program for over 3 hours by just scanning the am band.  I found it on 4 different stations…  Talk about your “Canned Programming”.

Sorry as this is starting to look like a “Rant or a Soapbox moment” …

If you followed the above link you will see where you might go on Next Monday to voice your support…

Enjoy your weekend and let hope for good WX

Never ending noise level fight

May 14, 2009

Hi Guys,

Yesterday I decided to try again in my fight against the dreaded noise level I have at this QTH and I am sad to report that the score is now NOISE 6 Bob 0.

Yesterday I tried installing a hamstick dipole on a 15 foot mast on the North side of my property.  That would be 20 feet North of the South side of my property where I have the feed point of the inverted L antenna.

It had suddenly dawned on me that I did have the Valecom Coupler clamped on to the north fence post and I had switched over to the south side after…  I figured that why not give it a try as I have all the pieces laying around …

However NO JOY again….

So far I have tried  (1) Extra Grounding (Radio, Tuner, COAX, Masting)   (2) Extra Ground Radials   (3) Direct connect to antenna- No Balun  (4) Connect to antenna using 4 to 1 balun   (5) Change of antenna to Inverted “L” from vertical.  (6) Inserted Yaesu FC 40 Coupler in place of 4 to 1 balun  and now I am starting to run out of options….

The only thing I can think of now is that despite what I’ve been told it has to be something in the VALECOM Unit itself or an outside chance that the metal case of the VALECOM Unit was acting as a shield and preventing the noise from coming in.

I am open to suggestions at this time….  Here is the station set-up as we sit right now….

Yaesu FT 847 being powered by a marine battery.  LDG Z100 auto tuner.  The LDG and the Yaesu are grounded to a cold water pipe by approx 8 feet of copper strapping.  I then have 30 feet of RG8X going out the basement window to a grounding block that is attached to a 5 foot length of copper pipe that is approx 5 feet in the ground.  From there a short run of RG8 coax runs to the 4 to one balun where the inverted L starts.  I have one approx 70 foot driven element which goes up approx 25 feet in the tree then over the roof of my unit for the remainder of its length.  I have 3 countepoises attached to the grounding block two of them are approx 33 feet in lenght (used to be a 40m dipole) and the final one is 17 feet long.  These radials/counterpoises are approx 4 feet above the ground and run along the inside of my fence with goes around the perimeter of my back yard…

I have tried swapping out radios, tuners and coax runs with no luck.  If I disconnect the coax from the feed point the noise drops almost to zero which makes me believe that it is something being picked up by the antenna itself.

I have tried using my FT 817 which does allow for using two different antennas.  I used VFO “A” on 3.755 and the front antenna jack with a6m dipole attached at 5 feet above ground.  I used  VFO “B” on 3.755 using the rear antenna jack and the inverted “L” and the auto tuner.  I then operated split xmitting on VFO B and using VFO A for RCV.  Using a non resonant antenna with it at a lower altitude did reduce the noise a bit so I am thinking that someone in my neighborhood  has some sort of electrical device out there that is adding to the noise level I pick up on the 80m band.

The noise is the worst on 80m,  less on 40m and 160m, and hardly noticable anywhere else on the HF bands…

The guys who did the window work here this week warned me that they had heard that hydro will be in later during the summer to replace a few transformers and run new underground lines to the units so don’t do any landscaping yet.  Although we already have underground wiring I am hoping the upgrade will eliminate parts or all of my noise problems as I have tried everything else I can think of….

Do you have any suggestions other than move????

Monday Morning in Ottawa

May 4, 2009

Hey… We are off to a good start on the week as I was able to sleep in till 0730 when “Toby” decided he needed to go out….  And he calls himself “Mans best friend!!!”  If he was then he would sleep in till at least 9am…  But on the bright side its better than the 0600 wake up I got yesterday….

Back to radio stuff for a while….

This morning while the house was quiet (everyone else was asleep) I grabbed my flashlight and headed down into the shack.  I powered up the FT 847, which normally runs off battery power and checked my noise level. On 3.755 LSB after tuning the antenna with the auto tuner my radio was setting an S9 level on the meter.

I then started flipping off the circuit breakers in the house and was listening at the same time.  No change in the audio level of the noise….  I continued flipping off the breakers and I am now sitting in the dark.  Using the flashlight I check the meter and nothing is moving…. nothing is changing…. the house is using no power.  Now to my ears nothing has changed with the noise level, so I go over to the radio and my fears are confirmed.  The noise is still at the S9 level.  No change!!!

Now if I go outside and disconnect the coax at the balun for the “Inverted L” my noise drops to “S1″ and if I disconnect the coax at my LDG auto tuner end the noise also drops to “s1″.

This is confirming to me that the problem is a signal (harmonic???) somewhere close to the 80m Amateur Band that my antenna is receiving.  The next steps would be to attach some sort of small antenna on my FT 817 (my only true portable radio that covers the 80m band) and go sniffing around the neighborhood to see if I have any chance of finding the source.

That most likely will happen next week…

This week for the most part will be spent getting the equipment ready for the next LASA Flights- )BTW they have updated their website over the weekend to reflect the new flights).  Last week I checked out the APRS equipment and the FT 897 with my vertical J Pole that will be handling local VHF/UHF Voice comms.   I also have a 1/4 w vertical for 6m installed but the only repeater that I can reach is in Ottawa so we could cover that on 2m…

This week I have to install my Cushcraft 10 element (5 on VHF and 5 on UHF) and hook everything it to my FT 857 with it aimed roughly east but it will be adjustable from North East though to South East to accomodate the repeaters North of Montreal- in Montreal itself and the repeaters south of Montreal or in Northern NY State.  This will give me coverage approximately 250kms east of Ottawa depending on where the balloons go…  A little less if they go North East as there arn’t that many repeaters up there but it it goes South East there are a couple of long range repeaters in Eastern NY that will get me voice comms into the State of Vermont.  Remember the first flight made it as far as Maine thanks to the jet stream…

On the topic of Balloons there is still no word why PBH-10 was scrubbed…  The web site just says to check their Twitter site

In addition as I still have the high noise level problems I guess I will have to take the Transportable Station (30AH battery/ FT 857/ 80m Hamstick Dipole) out to the park to check in to the Ontario Phone Net a few times this week to keep up with the paperwork.  Then there is the social side of the hobby which also is my favorite and thats Ragchewing…  The trick is to get the noise low enough that I can hear old firends so I can talk to them…

So thats how the week is starting to look…  No doubt there will be more additions but its a good start…

NEW VIDEOS POSTED ON YOUTUBE SITE

April 24, 2009

Today I decided to show you what I am talking about with my HIGH NOISE LEVEL and my attempts first to lower the level of noise from S9 down to something that lets me use the lower bands.  As that has not worked I have downloaded a DSP Filter from the net and I now run the audio output of my FT847 to the Sound Card Input of my laptop.  The DSP Program does it best to filter things out and then sends the output to either my headphones, external speaker or in the case of todays 2 videos to my speakers built into my laptop.

For those of you who are not up to speed on my Survivorham work this is video in the rough.  I am not a camera operator or producer.  I make the Videos for the purpose of demonstrating what I am trying to explain so no awards winning work will be shown here…

The phrase “a picture is worth a thousand words”…  looses some of its value here but it does get my point across…

The links are here

40 M BAND NOISE

80M BAND NOISE

Like I said….its not the best but it does get the point across….

For those of you who missed it from earlier posts.  My VALECOM HF Coupler which I bought very very used many years ago finally failed me due to water damage.  This was no fault of the unit as I should of made sure the access hatch was closed properly and that allowed the water to access the electronics side of things and thats where the problems started…

Now being CHEAP (I’m a ham remember) I have tried all sorts of replacement Items for the VALECOM unit as its a MIL SPEC unit and comes with a MIL SPEC Price and to be honest I can’t afford it…  The very used one I bought was at a bargain price of $12.00 at a hamfest if I remember correctly (or did I ebay that one???) and the replacement item NEW at VALECOM is only $500.00 plus taxes and shipping.  Thats more than I have paid for a few rigs so….

The drawback to that is as well as being a coupler the VALECOM unit had some sort of filtering system built into it as now (most likely the unit was built for somewhere in the 2 meg to 5 meg area area as I greatly reduced my noise level coming into the antenna. 

I am recieving an interference signal on 80m of S9, which is around S7 to S9 on 160m, which is around S3 to S5 on 40m,  which is not an issue on 10,12,15,17,20m and barely noticable  (around S3) on 30m. 

To better explain how its used….My long wire antenna is hung through the trees and attaches to the “Positive” post on the Valecom unit.  My two counterpoises (like radials) are attached to the inside of my yard fence and then attached to the clamp that secures the Valecom unit to a small metal mast and then that clamp is then grounded to a ground stake.  My coax then goes from my FT 847 to myLDG auto tuner and from there to the Valecom unit. 

Now since its untimely demise I have tried many different ways of installing things with various couplers, connectors and baluns and although all of my attempts have worked as far as “loading up for transmitting” go , none of them have addressed the interference coming in though the antenna itself.  I know its the antenna itself (which attached to the Valecom unit) as when I just have to coax outside but not connected to any coupler etc the noise drops to almost zero so it has to be coming in through the antenna.  Something in the Valecom unit was filtering that out….

Some of my attempts have been interesteing as when I used a 4 to 1 balun in place of the Valecom unit) I was then able to use the longwire on 10m to 160m where I only had 10 to 80m previous.

So the saga continues…  With the addition of the 4 to 1 balun and the DSP Program on my laptop I have one more band to play with and much less audio noise to put up with….  But the signal that was generating (is generating) the noise is still there and so far my attemps to remove it have failed…

To bring it down to the basics…. I used to have a “noise barrier” that your signal had to be stronger than for me to hear you.  Now with the DSP on my audio side of things the barrier has changed from noise to invisiable but your signal still has to be stronger than the invisiable barrier for me to hear you. 

Enjoy the start of your weekend and I will be posting more either later today or early tomorrow am for the weekend events…
