[Elecraft] PX3 interfering with rig control to KX3?

I was using my KX3 to operate QRP during the California QSO party. I had my logging program (RUMlogNG on a Mac) connected through the PX3 to the KX3 using an Elecraft USB <--> RS232 interface cable. I noticed the computer was not getting the band and frequency information from the KX3. When

Marvin; Assuming that you have the AUX I/O cable connected from the KPA500 to the K3, and you have RADIO set to K3 in the KPA500 menu, then I suspect you have dialed the power down to 0 on the K3 when the KPA is enabled. The KPA tells the K3 its state when it switches to STBY or OPER. The K3

Re: [Elecraft] Mobile from 117 VAC

Most likely, the AC inverter built into the car does not produce a sine wave, and your radio probably won't like it. You could just connect some heavy wire, with a fuse, directly to the battery terminals, and run the radio on that.  However, car batteries don't deep cycle well at all, and

Re: [Elecraft] KPA500 problem

That is a mystery. The KPA500 is simply an amplifier, so it should amplify the K3S PEP power for SSB the same as it does for CW. Take a look at the drive power from the K3S. If you are overdriving the KPA500 in SSB, it may be switching in an attenuator. That could result from having too much
