Re: Problems with audio tones (in RX) with uBitx v #ubitx #v5

 

Hi Evan, thanks for the quick response. I (once) again recalibrated the system but that did not resolve the issue. The birdies are very strong (loud), they are comparable with an input signal of -70 dBm. When I short the input of the BFO mixer (CW-2) the birdies are still there, but when shortening the output of the BFO mixer (TP20) they are completely gone, is it possible that it is injected via the clk#0 signal (mixed with clk#2)?

Any idea what to try next? Currently I only have a scope and signal generator and HF RTL-SDR, but I have ordered a tinySA.

Thanks, Albert
