I'm sure there must be a good reason for wanting to transmit on the 2.5 MHz
band, but I'm just behind the times and don't know what it might be. At any
rate, I still think the best approach is to use an Aux board and they can
easily be homebrewed. One advantage to the Aux board approach is that the
synthesizer is set to the correct 500 KHz segment and you don't have to hit
the up or down buttons to get to the right band segments. That of course is
true with the WARC bands when using an Aux board, but I seldom see it
mentioned.

FWIW, in John Loughmiller's (KB9AT) book "A Family Affair, the R L Drake
Story" on page 145, Steve Rawling, G4ALG is credited as saying that "To
enable the TR-7 to transmit on all frequencies 1.5-30 MHZ (excluding 2.5
and 5.0 Mhz bands) simply unsolder collector Q9001 on the DR7 board."
I beleive Jim's thread was to be able to add those bands back in with his
mods w/o defeating the out-of-lock inhibit. I know that my TR-7 (actually
John's backup rig) is TX on all bands and the out-of-lock inhibit is not
cut. I just tried CW on the 2.5 and 5 Mhz bands and it works fine. A
caveat is that I do have an aux board installed with 10Mhz prgrammed. My
aux switch it in the normal position.

This simply stops the TX inhibit signal from U9003 Ham Band PROM. 73,
