[1000mp] Odd tuner behavior

[Brian Smithson]

Well if it's not one thing I guess it's another.

Today my MkV started acting up with its tuner. It works great on 80, 40, 30,
15, 17, and 12, it does the right thing. Tune within the band it the WAIT
light flashes as it finds its new spot.

On 20, the WAIT light stays on all the time - it doesn't matter mode or
frequnecy. Pressing and holding Tuner to make it tune results in a transmit
but no tuner action. I have to press Tuner again to stop the transmission.
The SWR seems to hover between 2 and 3, but it's only with the tuner engaged
that I see those readings - without the tuner, it's below 2:1.

On 10, the WAIT light stays on But pressing and holding the Tuner button
shuts the tuner off with the HISWR light. It doesn't try to tune. I can turn
the tuner back on, but WAIT stays lit again. Even WITHOUT the tuner, the SWR
meter pegs when I transmit. I have two antennas for 10 and it happens on
both. My RF-1 shows nice low SWR on each.

Is this a variation of the 'out of tuner memories' problem I've seen posts
about? If so, is the only way to clear the tuner memories to clear ALL
memories too?
