more questions:

have you had time to check the dynamics of the agc ?
can you tell me what level in dbm you have at the output of the tx before the mixer ( 9mhz ) ?
many thanks

Unfortunately, due to Russia's multiple attacks on power plants, we are now in serious trouble.
There is no electrical power for 12-15 hours every day. This significantly limits my options.

Hello , very good job, is fantastic...
I have the question :

1) what is the minimum level of the threshold AGC ? 5 uV around -93 dbm ?
Would it be possible to bring it lower ?.. around - 110 dbm ?
2) what is the total dynamics of the agc ?
3) what is the level local oscillator of the bfo ? p4..
many thanks
