Question on RX Calibration Antenna Selection and Persistence?

Mike Krzystyniak

Over the years I have used RX calibration periodically. My only antenna is on Ant2. Here recently RX Cal stopped working (making a measurement). A quick assessment shows RX Cal now switches to Ant1 to make the measurement and with no antenna on Ant1 the Cal error value comes back with zero ppm. I don't recall it working like this before. Changing it to Ant 2 mid stream it measures the PPM error similar to before, but now it will not remember to use/stay on Ant2 the next time. No persistence. I'm on SSDR 2.6.1 here.
Which way should this work? I thought it should measure from the selected RX antenna.
Thank you 73 Mike K9MK

The RX calibration is only done on ANT-1 and this cannot be changed. You should not switch antennas in the middle of the calibration as it will generate invalid samples during the antenna switch. If you need to run the calibration, you will need to connect an antenna to ANT-1 that is capable of receiving WWV signals.0
