I was noticing that when I hold the ATU TUNE/ATU MODE button, the BYPASS
led above it always stays on.
The IN led will switch on and off as I hold the button a second time, but
the bypass led will always remains on.
I don't hear any relays latch.
This happens on all bands, except for 30m.
On 30m, holding in the button, releasing it and holding it again will turn
on the IN led, and then the BYPASS led.
I can hear the relays latch into place as it goes from in to bypass to in...
On all bands tapping the button will put the amp into tune mode. All normal
there.
Something doesn't seem right with the ATU if the bypass and the in led are
on at the same time.
Perhaps this could explain my other problems.
SN 209. Arrived 6/2, ordered late Oct.
Thoughts, ideas?
Bill, K1SM
