Re: [Elecraft] PX3 - odd 'missing' signal
It's an artifact of the architecture of the radio - the Zero-hz crossover. You can move it by changing the menu item RX SHFT from Nor to 8.0. This is a per-band setting. Be aware that changing RX SHFT prevents using the Dual-Watch receiver, and takes the Roofing Filter out of play (if installed). Another method to move the artifact when working CW is to use CW Rev. This will shift the artifact to the other side of your VFO A cursor. 73, Chris K4HC Date: Sun, 15 Feb 2015 19:23:16 -0500 (EST) From: d...@lightstream.net d...@lightstream.net To: David Orman orma...@corenode.com Cc: Elecraft Reflector elecraft@mailman.qth.net Subject: Re: [Elecraft] PX3 - odd 'missing' signal Message-ID: 64786.71.74.118.201.1424046196.squir...@mail.expedient.net Content-Type: text/plain;charset=iso-8859-1 I have noticed this null as well. In SSB mode, the null is right at the carrier frequency. In CW mode, the null is offset from the carrier frequency by the amount of the sidetone pitch. Engaging ALT switches the null to the other side of the carrier, again by the amount of the sidetone pitch. I don't recall seeing this on earlier versions of the firmware (though that doesn't mean it wasn't there) Firmware versions here are: PX3 Firmware version: 01.16 KX3: uC: 02.30 dsP: 01.32 73, Dale WA8SRA I've noticed on various modes/combinations of spans, I show some what look like null regions. Sometimes it's right where I'm tuned, sometimes it's offset. In this picture, I am tuned to 14.055.050, in CW mode, span is 2, and there is a deep null area centered somewhere around 14.056.05. In some modes, this is troublesome, especially when it's right on the cursor where I am tuned. I must be doing something wrong, so would appreciate any feedback you can give me regarding this / how to fix it. Here's an image showing what I am talking about: http://ormandj.corenode.com/images/radio/elecraft/px3-null.jpg Thank you David __ 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] I can hear stations on other side of Zero beat
Thanks Tom and Don for helpful advice. I will try Spectrogram to re-setup the filters. So far I just set them up using the data in the table in the manual.

If you have a PC available to use (even if only temporarily) with your K2, you might consider going to my web site and downloading Spectrogram v5.1.7 and the written docs (immediately below the Spectrogram link) which specifically detail how to use Spectrogram to ACCURATELY adjust your BFOs so that the filters are working as well as possible. That should address your problem. The ONLY 'additional' device you'll need will be an audio (monaural) cable to go from the K2 SPKR output to the MIC (or LINE) IN input on your PC. Spectrogram and the docs are available at: Spectrogram: http://www.n0ss.net/spectrogram517.exe Documentation: http://www.n0ss.net/k2_filters_using_gram_v5r17.pdf Shout if you need any help.

However, I have noticed that I can hear CW stations on both sides of zero beat when using the widest (1.5kHz) filter setting. It's not just a weakly audible signal for very strong 59+20 signals, which I would expect. I can hear a 59 signal at S7 or S8. With the 0.7kHz signal this is not the case, so I presume it is to do with the way that I have setup the filter and the BFO. What have I done wrong? Any ideas? I set it up as per the instructions in the manual.
