Don. WSPR is AFSK with a very small shift at a very low rate. My thinking is that if a stepwise frequency correction was made during a transmit or receive period, it would cause a corresponding shift of the VFO which might be enough to throw the decoder of the receiver. I don't know, that's why I

As Jack points out, the ATU belongs AFTER the KPA500 if you are using non-resonant antennas. if you are using some resonant and some non-resonant, and you want to use the KAT3 for the non-resonant, then attach the resonant antennas to the KPA500 and the non-resonant antennas to the other

Like most hams, I use an antenna tuner on some bands. When I switch to those bands, the amp will automatically switch but of course it will have to be put in standby so I can adjust the tuner. I'm sure this is a common situation, shared by many others. The auto-bandswitch function of the amp

Hi Ian, Jack is incorrect. It is not as critical as he implied. I operate often into high SWRs with my K3/KAT3 running through the amp in bypass mode. I'll discuss this with the team here and get back to the list with any bypass mode operating limits. 73, Eric On 4/6/2011 1:55 PM, iain

There is one other consideration with mentioning, and that is that because the LP-PAN uses your computer's sound card, it is at least theoretically subject to image problem as a result of amplitude and phase imbalances between the I and Q channels, where the SDR-IQ passes those data in digital

If the amp is in standby the amp should do whatever it needs to protect itself from high swr or whatever. The other options suggested seem a bit out of the ordinary to me. I will probably buy a LDG tuner anyway as I understand the KAT500 is still in design. The LDG unfortunately does not

Just a couple of extra thoughts. I use an SDR-IQ as a panadapter on the i-f output of my K3 and it works (*almost) flawlessly. (*I have never found anything with a microprocessor in it to work completely flawlessly). So the SDR-IQ can be used both as a standalone receiver with decent
