[TenTec] Orion II bug, or operator error?

[RaySoifer at cs.com]

Hi,

I know this sounds like a stupid question, but i haven't encountered this 
situation before, so please humor me along.

I was trying to work an Armed Forces Day station, NAV3, who was on 13974, 
listening 14254.  I tuned him in on the sub rx but when I attempted to work split 
with the tx on VFO A, the radio wouldn't do it.  Outside the range, it said.  
Has anyone else had this problem?

As you can now see, this situation comes up only once a year.

Tnx & 73,

Ray W2RS
