I've noticed the same kind of issue at times, also. I've never known to what to attribute it to. To be far, it's not just Elecraft rigs. I think it may be software glitches rather than transceiver problems. 73, Carl Sent from my iPhone === Carl Jón Denbow, N8VZ 17

Harry, This isn't a switch it on and off again problem I am afraid. It is simply that the KX3 Data Mode is restricted in bandwidth at the low end, unlike the SSB mode on the same radio. Bizarre but true. 73 from David GM4JJJ > On 3 Jan 2017, at 00:00, Harry Yingst via Elecraft

Nick, Thank you for bringing this up. I never did get a satisfactory explanation, I contacted support too but that didn't get me anywhere either, I don't think they understood my question, which is quite simple really, why can't we get the same bandwidth in Data mode as in SSB mode? I think

Jörg in the Elecraft KX3 group on Facebook had an interesting observation: with WJST's waterfall, if the "flatten" mode is on, it produces some unusual artifacts in the presence of sharp spectrum drop-offs, and indeed if I turn off the "flatten" feature and manually set the zero point for the

[Elecraft] Audio artifacts in DATA A mode with KX3

2017-01-02 Thread Nicklas Johnson
I'm seeing some unexpected audio artifacts when using DATA A mode with the latest production firmware on my KX3, on all bands. This is something I observe when the PBT BW is set all the way wide (4KHz) and FC is centered. In DATA mode, there's an audio drop-off between 200 and 325 Hz, with an
