Good day all.
This is a question for Flex digital mode users working with MIXW. The info
below is from the flex wiki site. They cover RTTY and PSK. A colleague and
myself are looking for the same info as it pertains to Olivia (in
particular, the TX / RX Freq). If this info has already been collected, we
would like to hear from you. We thank you in advance.

>From the flexradiowiki.com site, we have the following guidance:
An Operational Consideration for Digital modes
Traditionally, when one operates PSK modes or other digital modes, the
receiver is set on a common frequency (14.070 ) and tuning for PSK signals
is accomplished by click tuning within the modem frequency display. While
this works very well most of the time and is a good place for beginner to
start, it does not take advantage of the PSDR filters and frequency display.
Most PSK modems have filters that approach those in PSDR, but they are
outside of the AGC loop (i.e. a weak desired signal can be suppressed by a
strong signal within the receiver passband ). The alternate approach is to
set a narrow filter in PSDR and then do all of the (click) tuning with PSDR.
For RTTY; PSDR use DIGL
1. MixW > Mode
1. Select RTTY
2. MixW > Mode > Mode settings
1. TX Frequency > 2210
2. RX Frequency > 2210
3. Uncheck AFC
4. Uncheck Snap
5. OK
For BPSK31, etc. ; PSDR use DIGU
3. MixW > Mode
1.Select BPSK31
4. MixW > Mode > Mode Settings
1. TX Frequency > 1500
2. RX Frequency > 1500
3. Uncheck AFC
4. Uncheck Snap
5. OK
Repeat 3 & 4 for other USB (DIGU) modes.
