Connecting the RX directly to the antenna and the spurs are not there, the spurs are coming from the KPA500, and only when the KPA500 is connected to a radio (happens on all my radios connected to the KPA). Have tried the amp on 220 and 120, same issue. The KPA500 can be connected to a dummy

described has been exactly my experience. Using the PX3 I tune to the left peak, and it decodes well every time. Tuning to the center does not work. CWT has never worked well for me. David On Wed, Jan 21, 2015 at 2:59 PM, Gary - NC3Z nc3z.g...@gmail.com mailto:nc3z.g...@gmail.com wrote

I wanted a desk mic to go along with my KX3 station. Wanted something more portable than the Heil boom and mic I use on my other radio. I have experimented with dynamic mics on the KX3 and didn't get the results I liked but did get very nice results with using 4 CUI electret condenser mic

Well one of the things I have found that the PX3 helps with is being able to more accurately and quickly to tune in a PSK31 signal verse using the CWT Tuning Aid. I set the PX3 span to 2 or 3KHz and tune the VFO so that the PX3's cursor's bold line is on one of the 2 PSK signal peaks. If you

Jim, I have also had these reports when I tried to use a dynamic mic such as a EV664A and Heil PR22, it gets pronounced at the mic gain and compressor is turned up. I don't think there is any setting you turned on. Because of this I have gone back to electret mics. Will be watching to see what

This has actually been a topic of several discussions on the KX3 Yahoo group. If you look at the KX3 on a spectrum analyzer you will see that when the compressor is turned on that the TX BW goes from about 2.8KHz to 2.4KHz. I have asked Elecraft if there was a way for another option to be

I think the KX3 form factor works out well as a home station. The face is larger than a lot of other radios and in my opinion the ergonomics are better than the K3. My KX3 station (KX3 and KXPA100) is my second home station to my FTDX5000MP and the the station I take to my second QTH when we
