Re: [Elecraft] PX3 Anomaly?
Push on each one of the plugs in both the PX3 and the radio. This can be caused by a poor connection. -- Sent from: http://elecraft.365791.n2.nabble.com/ __ 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
Re: [Elecraft] PX3 Anomaly?
What is your CW offset set to? Perhaps that is a cursor showing the CW offset? 73, Scott N9AA On 6/27/19 2:45 PM, Ian Kirkpatrick via Elecraft wrote: Hi, I have recently purchased a new PX3 for use with my KX3.In CW mode in the waterfall display there appears a distinct black line 600hz to the right of the carrier, the black line is 50hz wide.Is this normal or is there a fault with the PX3 or is there something I have not done in setting upprocedures?I will be grateful for any guidance.Regards,IanG4WTF __ 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 scott.man...@gmail.com __ 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

Re: [Elecraft] PX3 Anomaly
Both of these problems have been reported here. The second problem is better but still exists. On the first with the blip that is offset I use the workaround of operating CW with a reverse offset until they get it fixed. At least there isn't any off set used on field day.

Same thing on every band I’ve tried – 10, 15, 20 and 40.

The spikes remain at 600 and 700 Hz offset from center regardless of the span setting. Weird. And troubling, because 300 - 600 Hz is a typical XIT offset I use in pileups when the DX isn’t working “up.” Anyone have any ideas? Anyone seen this before? The other glitch is much less trouble. The KX3 setting sometimes switches itself from PA Mode On to PA Mode off. I think I’ve figured it out – if I turn the KXPA100 power off before turning the KX3 off, or if I turn the KX3 on before powering up the amp, the KX3 must be sensing “no amp” and so switching itself back to PA Mode Off. But then when the amp comes on, the KX3 doesn’t sense that and switch back to PA Mode On. An intelligent default choice, maybe. Any way to defeat it?

Re: [Elecraft] PX3 Anomaly
For the KXPA100 issue (PA MODE ON to OFF), just leave the KXPA100 powered on full-time. This works in my mobile installation, meaning the KXPA100 is always available. This is not true if the KX3 is removed, when PA MODE will default OFF because of the missing KXPA100. My mobile installation has a switched circuit for the KXPA100 and KX3. If you have a separate power supply for the KXPA100, make sure it's on before powering on the the attached KX3. 73, matt W6NIA On Sat, 13 Jun 2015 23:39:17 +, you wrote: Finally got the KX3 PX3 KXPA100 system cabled together and on the air today, all of the F/W updated.
