PK232SAT.1 of 5
If you have an HF RTTY modem you can use this with the PK-232
to improve copy of AO-13, (as well as greatly improve
terrestrial HF operation of the PK-232) as the lack of individual
tone filters and 200 Hz shift of the PK-232 results in less than
optimum decoding. I found that with my HF modem's 170 Hz shift
(which is AO-13's RTTY tone shift) and separate tone filters I
can copy AO-13 RTTY telemetry from horizon to horizon error free,
while the PK-232's internal modem will return occasional errors
until the signal reaches a high enough strength to overcome the
PK-232's modem's bandpass (not separate tone) filtering and 200
Hz
shift limitations.
Also on HF RTTY I can copy weak signals with a greatly reduced
error rate.
