Calibration of an HF+

f1hdi
 

Hi,

I forgot the easiest way to calibrate an HF+ (yes I have a HF generator capable of <1Hz precision @ frequencies < 800MHz)

Is following the method hf+-ppb.exe the best way ?. I am 400Hz+ away @145MHz so I need to calibrate (WSPR use)

hfplus_ppb is fine for this task. You can also ise SDR# in debug mode.
