John/All,
I just remembered from the "mode" list that there were some that were over
300khz.
Good to hear that about the Yaesu. I sensed its DSP and other options were
"limited". This is not the case with the 7200 and not with the 7000. I have a
7000 for "portable" purposes and it is an awesome radio in my opinion. I am
sure the 7200 closely resembles it and that is mostly why I am considering
it... It has plenty of options and may include other "improvements" as well.
Thanks for the input.

Hi Josh,
I have an FT-450 and I would NOT recommend it for Pskmail activities.
Two issues I have with it:
1. I can't get a 500Hz passband for digital modes used in Pskmail (PSK250 is ok
in a 300Hz filter, but not THOR22, MFSK32 and PSK500/500R).
The FT-450 requires some convoluted set up using split modes (CW RX on VFO A /
USB TX on VFO B) to do this. Therefore it is not manageable from the server
without significant code change. I am then stuck with using it in USB Data mode
which means using the IF shift and the notch to achieve a resemblance of proper
filtering, but it is far from adequate.
2. It locks itself up from time to time. I have had to perform a full reset to
get to work again once. I have put toroids on all data and control cable in/out
of the unit and that seems to reduce the lockups but not completely (If I do an
auto-beacon I have to reset it every week or so).
I also note that it resets itself from time to time when using it manually too.
So I am not impressed with the robustness of FT-450 and I am disappointed when
the DSP is capable of doing what we need but it is deliberately limited by
Yaesu.
I prefer my FT-857 (would have been better with an FT-897) for running the
Pskmail server.
Just my experience.
Sorry I can't comment on the IC-7200.
All the best,
73, John
