Replying to myself...
an RC low-pass filter, with a -3 dB corner at 2.4 kHz
After finding a better scan of the receiver schematic, what I thought was a 2k resistor as R34 is really 1k, so the corner is 4.8 kHz. Based on that, I doubt even more the HF roll-off is the reason your calibration is failing. --- Jeff WN3A --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
