Dear Elecrafters: This weekend I put my new K3 + XV-144 on EME using JT65 for the first time. I have these questions:
1. Using USB, I got a 20% TX power fluctuation depending on the tone being sent. By going to TX ESSB, this is reduced to about 10-15%. Is there a way to even out the TX power? My previous rig (TS-2000) would send the various tones with only a few watts (out of the 500w amp) variation. I tried compression as well, but it didn't help much at low compression settings. I also tried the TX EQUALIZATION but I think the bands overlap the tones. What's the best strategy here? 2. The first station I worked off the moon reported my TX signal being abt 600 Hz high. My XV-144 has the xtal oven and had been on for an hour before I got on the air. I was able to dial this in using XVTR OFFSET, but I had to set it to +600 to move the signal down 600Hz. Shouldn't this work the opposite way? 3. While monkeying with the XVTR OFFSET, both VFOs locked on the K3, every time I would change the parameter and exit the menu VFO A would be set to 144.200, and the preamp would be on when I had turned it off and set the attenuator. Is this a possible firmware issue? It would be easier to fiddle with XVTR OFFSET if these other parameters just stayed locked. By working several stations of known frequency accuracy, by subtracting the calculated Doppler shift from the actual frequency difference I managed to get the XV-144 pretty close in frequency I think. Did I mention I LOVE THIS RIG!
