MCU 2.15 / DSP 1.84, 7-8-08
* MEMORY RECALL ON 6 M (CW REV, etc.): Corrected recall of
CW normal/reverse selection and other parameters on 6 meters.
* 50 AND 100 HZ bandwidths are now available in DATA A (for use
with PSK31 and other narrow modes).
* SYNTH TUNING CORRECTED ON 80 M: Downward tuning of the VFO was
sometimes
leading to loss of receive and/or transmit at certain frequencies.
* SYNC DATA: Selecting sync data or “-S” now ensures that the
same crystal filter will be used for both RX and TX -- either 2.7 or
2.8 kHz.
(Sync data mode, enabled by assigning PF1 or PF2 to CONFIG:SYNC DT,
can be
used to minimize the error rate of AMTOR, PACTOR, ARQ, and similar
modes.)
While -S is in effect, the receive crystal filter cannot be changed
with
XFIL, and SHIFT/LOCUT/HICUT are unavailable. WIDTH can still be
changed,
but it will affect only the DSP IF, not the crystal filter. The RX
and TX first I.F.s will thus remain identical, a requirement for -S
operation.
