I'll bet the simplest / cheapest solution would be a couple of RF relays and
a used SB-220 with a tuning preset template placed over the load and tunes
controls that you could throw in the line while you were waiting for the
Alpha's filament 3 minute timer to cycle. $500 bux and you would never
have to touch the inside of the Alpha. It would also provide a hot standby
in case the Alpha failed outright during the contest. If you needed 160
meters, a Drake L-7 would be a good, but slightly more expensive solution.
