This is what we could expect but it it not true, but if Tentec fixed 
that in the firmware! The problem was first reported by W5GN, and fixed 
in WT version 2.7.0 (Feb 7, 2005).

You can try with WT version 2.5.2 
(http://download.win-test.com/wt-2.5.2.exe): set the filter to a custom 
value on the radio, then enter whatever frequency in the callsign field 
and validate. The radio will move to that frequency but the custom 
filter setting will be lost and revert to a default one. At least with 
the 2005 firmware of the Orion...

Ok Andy, I just missed that! That means that Orion II is also quite 
eligeable for the "Pass to Sub VFO" bandmap feature.

Thanks and 73,
