Re: [Elecraft] FIELD DAY PREP
Those transceivers are noted to have that issue. They are very popular and there are thousands of them on the air today. And we are always concerned better receivers. How about cleaner transmitters. That company did correct the problem but only with releasing a new model. You aren't the only instance of those causing a problem. 73 Bob, K4TAX On 6/14/2019 11:59 PM, Vic Rosenthal wrote: One of the worst FD problems I’ve experienced was a Japanese transceiver (I’ve honestly forgotten the brand) in the SSB tent that transmitted a wideband hiss whenever the PTT was closed.

Re: [Elecraft] FIELD DAY PREP
Over the years I have been bitten by some tenacious flying insects. The tiniest are the no-see-ums. They will drive you crazy. The largest were in Arkansas. I swear their mosquitoes were as large as small sparrows and could take a pint of blood at each involuntary donation. But the largest swarms were a little north of Marquette, Iowa. My late wife and I were touring the area near where I grew up when we visited Effigy Mounds National Monument. She wanted to rest in the high humidity of a July afternoon. I pointed to the cloud about 100 yards away and told her we had to keep in front of it. She, life long native of Washington County Oregon, had no idea what I meant. Stubborn Swedish blood wanted to make her own mind and donate it. I advised her she would be eaten alive and kept walking the trail. A few minutes later she caught up to me and kept her opinion to herself. We got to the parking lot and left the park without comment. Kevin.

Re: [Elecraft] FIELD DAY PREP
Scott, my recollection was that SS7 only affected the call setup but not the transmission characteristics. It has been a while ago but that is what I remember. I believe that the REAL problem was that the system slowly evolved from a battery and ground to a pretty complicated analog/digital transmission system. Those that started with the old common battery telephones JUST KNEW that you had to talk louder on a long distance call.

Re: [Elecraft] FIELD DAY PREP
I've started sending discreet emails to ft8 ops who are overdriving and including screenshots, trying to make clear "it isn't the power, you're overdriving". There isn't a well-known public resource to provide that kind of feedback today. I've considered setting up an sdr dongle and toolchain for 20m as a resource for stations in the San Jose area. (Ideally, I'd set up a second one at someone else's place so I can clean up my own output!)

Re: [Elecraft] FIELD DAY PREP
So was the issue the result of poor shielding and connectors of cables inside the trailer or actual antenna separation? That would do it. And could the SSB station be pushing the power and ALC and compression thus likely causing distortion and splatter? That would do it. One of my major pet gripes for net control operators and contest operators is the fact they believe turning things up a bit with the thinking they will be heard a bit betterWhen in fact they are making their signal more difficult to copy.

Re: [Elecraft] FIELD DAY PREP
Good morning, Bob . . . We normally use 75-100 feet separation between dipoles aligned end-to-end, and have had no problems over the years. However, last year we were limited to less than 50-feet separation and I noticed the Carrier Operated Relay (COR) in my K3 was kicking on occasionally from the SSB station with which we (CW) were obliged to share a trailer. I tried a TRP-150 for the first time on the air this morning and a station in Michigan detected no clicks, truncating, or other aberrations. We'll see. 73, Kent K9ZTV On 6/14/2019 10:24 AM, Bob McGraw K4TAX wrote: With stations running 100 watts or less and reasonable antenna separation, I've found no reason for a Receiver Input Protector.

oops... I meant to say: Inverted V dipole and verticals are NOT allowed at W3AO 73 Frank W3LPL - Original Message - From: donov...@starpower.net To: elecraft@mailman.qth.net Sent: Friday, June 14, 2019 3:40:43 PM Subject: Re: [Elecraft] FIELD DAY PREP We use a dozen K3 transceivers at W3AO, we've never had a K3 failure despite running as many as four K3s on the same band (CW SSB Digital and GOTA).
