[GreenKeys] MD-522/GRC modem

Subject: MD-522/GRC modem


Have just gotten my GRC-106A on the air and am wondering if the companion MD-522
is worth looking for. From the manual, it is capable of 850 Hz and 85 Hz shift.
Transmit and receive. How difficult would it be to change the 85 Hz
shift to 170 Hz which would make it far more useful?

Any info or tips appreciated!
