[Elecraft] P3 Showing Transmit Signal
I noticed this weekend that occasionally during transmit instead of the scan freezing in place it would continue scanning showing only my transmit signal with only that signal appearing in the black waterfall. I don't have the P3TXMON. It never did this before. I was viewing the external SVGA monitor. Any idea why? 73, Bud W3LL __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
[Elecraft] P3 Showing Transmit Signal
This has been mentioned before but - if you want to consistently see your own signal (for adjusting audio, compression, Etc.) Here's how: Transmit a SSB signal into - say, a dummy load - and while in transmit mode, do a reset on the P3. ( I have one of the function keys set for a handy RESET.) When the P3 comes back on, the switch signal for the P3 has already been sent and the P3 comes up showing your own signal. Handy!

Re: [Elecraft] P3 Showing Transmit Signal
I wonder if this phenomenon could be related to N1MM+. I have never seen this happen before (without N1MM+ running). I was using N1MM+ logging with a lot of functions running. That might explain the delay. Interesting. Gene N9TF The K3 is supposed to send a command to the P3 to tell it whether it is in transmit or receive mode. Apparently sometimes that isn't happening for some reason. It could be an intermittent RS-232 connection between the K3 and the P3 or perhaps some software running on a PC is overloading the RS-232 with tons of commands.

Re: [Elecraft] P3 Showing Transmit Signal
I noticed this a few times as well with my K3S and P3. When it happened, I was running a frequency, and I would go into TX sometimes before the P3 would unfreeze and the P3 would display my TX peak, following my modulation. Seemed to maybe happen at some transition of the P3 going back to RX when I keyed the microphone. Also noticed sporadic freeze decay of P3 after stopping TX. Most times it switched to RX right away, but sometimes it hung up for a second or two. I thought I was seeing things! Any ideas out there?

Re: [Elecraft] P3 Showing Transmit Signal
Just wanted to share this tip from Al, as it worked. Although, I started by reducing the polling by 50% first, and that did it. Ran a bunch of CQs with quick TX/RX switching and all N1MM+ functions running, and no freeze ups. Still don't know what path switched though on three of those hang ups over the weekend when I saw my TX signal in the P3 without the P3TXMON. Thanks for the info Al. 73 Gene N9TF K3S 10057 -Original Message- From: Al Lorona [mailto:alor...@sbcglobal.net] Sent: Tuesday, November 24, 2015 7:56 PM To: Gene Gabry Subject: Re: [Elecraft] P3 Showing Transmit Signal Gene, you can tell N1MM+ to reduce the Radio Polling rate. Go to Config --> Configure Ports, Mode Control, Audio, Other... On the Hardware tab, click on the Set button for your K3 port and then select "100% Slower" from the Radio Polling list. This may help.

Re: [Elecraft] P3 Showing Transmit Signal
Hi Bud, I could see this these days, but it was my signal coming back from around the Earth when transmitting on 21 MHz. It was a good propagation with K=1 and SFI=121. I could hear it too. 73! de HA4AA Andras On 11/24/2015 08:55 AM, Bud Governale wrote: I noticed this weekend that occasionally during transmit instead of the scan freezing in place it would continue scanning showing only my transmit signal with only that signal appearing in the black waterfall.

Re: [Elecraft] P3 Showing Transmit Signal
We had a report at the November West Valley Amateur Radio Association meeting of one member who experienced "echos" from his own CW transmissions during Sweepstakes on November 7-8. He verified by listening to another nearby station that the echo was 1/7 second later, the time for a radio signal to go around the world. The K3's full break in allowed him to hear himself between the morse code units. 73 Bill AE6JV On 11/26/15 at 10:25 PM, arato.and...@wigner.mta.hu (Andras ARATO) wrote: I could see this these days, but it was my signal coming back from around the Earth when transmitting on 21 MHz.

Re: [Elecraft] P3 Showing Transmit Signal
That would be from me… Amazingly, this was on 80 meters, and was heard all over the bay area up into central CA. At times the “echo” was louder than the direct signal! There are at least two recordings from that event. Very strange, and extremely interesting. While it was ongoing, both 40 and 80 were open across NA. When it stopped, 40 collapsed to the point where the only signal heard was VY1AAA, and 80 became only local. In 40+ years of hamming, this is the first time I have experienced anything like that. I have to say, it was also very cool to experience. 73, Jack, W6FB > On Nov 25, 2015, at 11:38 PM, Bill Frantz wrote: > > We had a report at the November West Valley Amateur Radio Association meeting > of one member who experienced "echos" from his own CW transmissions during > Sweepstakes on November 7-8.

Re: [Elecraft] P3 Showing Transmit Signal
I finished the SSCW on 40 and while in QSK noticed my own echoes. I thought that the K3's QSK or sidetone had weirded out and was confused and bummed out about it until I listened on a 2nd receiver and figured out that it was my own echoes, although I didn't believe what I was hearing. I've never, ever experienced that, much less on 40 meters. It's amazing to hear confirmation from Jack that that indeed was what it was. Shame on me for blaming the K3... I have since made peace with it.
