[TenTec] OMNI-VII erratic TUNE / PWR

[GARY HUBER]

Last night while operating in the 160M CW contest,  the TUNE and PWR buttons of my OMNI-VII were erratic and difficult to get to work, requiring many presses to engage or disengage.

After reloading the radio update files several times, I started operating all buttons and switches to see if I could wipe the problem away. When I operated the MULTI control by pressing and releasing it several times, the TUNE and PWR buttons started operating normally. Switches need period exercise to keep the contact resistance low.
