What is not so very good...

I need some help with a little problem.
I wanted to make software-bandscope with the help of the second receiver (even bought an additional narrow filter for that, hi)

The idea was as follows:
program read the frequency of the MainRX and uses it as the main frequency for scanning SubRX. Depending on the selected width of the controlled frequency (Width = W), in SubVFO frequencys from QRGmain - W/2 till ORGMain + W/2 are being sent. The frequency of the first receiver is being read again and everything repeats.. So, bandscope is always connected to the MainRX QRG.

Due to the experience with the other programs I expected that the amplifier of the low frequency of the 2nd receiver might be closed. Actually I don't need it, because I was gonna listen on the main. But I was really surprised to realize, that the 1st was closed togehter with the 2nd...

If I scan with the 1st one, the only 1st is being closed... If they would be of the same quality, I wouldn't care much... But it's not the case...

Unfortunately, syntax of the CAT-commands in TRX manual is documented not very well . Maybe it's possible somehow to set the frequency (Set QRG) the way, that the audio amplifier wouldn't get closed... Maybe there is one bit responsible for that...

I have used commands F1 F2 F3 F4 0Ah for the main-VFO and F1 F2 F3 F4 8Ah for the Sub-VFO. Does anybody know how to solve this problem?

Or it's only possible to cut the wire, by which close signal for LF amplifier is transmitted? Hmm...
