I posted this query over on the NaP3 Yahoo group, but haven't gotten a lot of replies. Don W3FPR replied as did Larry N8LP, but still no firm resolution. If anyone here on the Elecraft reflector has a KX3 and is using NaP3, please take a look at this question and see if you've seen this issue and if you've resolved it:
My KX3 #5539 is connected to an iMac computer with the Elecraft serial-->USB cable. The RX I/Q port is connected to the iMac's Line In jack on the back. I'm running the current firmware release in the KX3, the Mac OS is at 10.7.5. I bring up NaP3 to see the CW signals on a band and I am seeing a "birdie" or "spike" (or whatever you want to call it) right at the pitch offset frequency. So, for example, with the KX3 pitch set to 550 Hz, and the KX3 sitting on 24.890.00, I'm seeing this thing at 24.890.55. I know absolutely it is the pitch frequency, because I can press & hold CMP and change the pitch frequency and the spikey guy moves with it. Fortunately I'm not talking about a 40db over S9 signal - it is more in the order of about S3 or so. But it is enough to be distracting when looking at the spanadapter and also enough to cover up any "blips" from weak signals underneath it. When I turn on the waterfall view on NaP3, I'm seeing a solid cyan line vertically right under that spike. I can move this spike to my "center line" by changing the global offset in the Configure>Rig panel to what my pitch frequency is. But doing so causes me to not be on a signal when I've clicked on it. Is there something in NaP3 I can do to get rid of this spike, or is there an issue in the KX3 that I need to follow up with Elecraft?
