Re: #ubitx Progressive 50dB+ Software based RX (and TX) IF attenuation. #ubitx

 

Might be possible to use John's 45mhz IF filter trick to attenuate CW also.

Currently, CW-KEY unbalances the first mixer at T2 pins 3,5 when sending CW.
We could have CW-KEY instead unbalance the second mixer, at T4 pins 3,5.
