Sorry, I was behind on reading my email and see this has been answered a
few times already....

Subject: RE: [TenTec] Orions SO2R in CQ WW RTTY
Hi,
Try this and see if it works on both of your Orions with Writelog as
it works with mine...
Set your mode to FSK on the main RX and VFO A and your bandwidth to
250hz. Press the mode button and choose USB. Now press mode and choose
FSK. Your default FSK BW should now be 250hz if you open Writelog, put
a few spots on the bandmap and try it out...
Let me know if this doesn't work for either of you as it seems to work
here.
It seems to work the same for each mode so I think you can set the
default bandwidth for each mode this way.
I had spent about 45 minutes testing the operation of Writelog and BW
documenting the changes to the rig when clicking on the bandmap for an
email I was going to send to W5XD requesting an ini setting for default
BW for each mode in Writelog. While changing modes to see if the BW
change was mode dependent (I tried 20 meter USB) I noticed the FSK
default bandwidth had changed when I switched back to FSK and Writelog.
This is probably a documented feature but I didn't dig the manual out.
Congratulations on the great CQ WW RTTY score Bob (and thanks for the
mult!).

Bob,
When the mode changes on the Orion, the filter command must be resent
from
the serial port. This was explained to me by Gary Barbour. If this is
not
done, a default filter for that mode is selected instead. I have never
figured out where this default filter gets its value. The bottom line
is WL
needs to resend the filter setting to the Orion after the mode changes.
This will cure the problem you describe.
