I went thru the procedure to adjust the bandwidth filters and everything went fine except I was unable to get a proper signal doing the crystal amp. alignment.
Both R31 resistor on the A11 and A13 board didnt help it.
I was unable to measure the 21.4 Mhz IF frequency (which I tried by taking the board out and measuring the input on the connector).
I also noticed, that I have a problem with a SPAN below 100khz, above 100khz its OK (no problem at <>10Mhz).
