Interesting “feature” with my At-1000 pro 2. When I tune on 10m it will sometimes tune a good SWR, but the band sounds dead - no noise, no nothing. A retune and the band is full of life. This only seems to happen on 10m. Using an end fed long wire. Any ideas why?

My AT-600 ProII does the same thing.? It is not going to bypass because the SWR is good, but signal levels are down 10 dB or more on receive.? IF I go to a different frequency and retune, the signal levels come up.? I am using it remote with a 25' unshielded cable for control.? I have ferrite clamp-ons on the control cable at the antenna, but my suspicion is that RF on the control cable is interfering with operation.

As far as I know the AT-600 and 1000 do not go into bypass after tuning, wish they did.

The only way I have got them to go into bypass after tuning is to use the other ALE program, connect the LDG USB device to the meter port and set the parameter in the program to control these tuners.? Have not figured out a way yet to do this with ION2G.

If you find a way please let me know.

A momentary (very quick) press of the TUNE button puts the AT-600 into Bypass mode, whether you just tuned it or not.

The question is, if you need it to tune, why would you want it to subsequently go into bypass mode?

Lyn, I have also been wondering about the bypass/quick/full tune button setup since the AT series was introduced - very awkward function combination! ?The timing gap between a quick tap to bypass and a 0.5 second press to quick tune is just too narrow.. ?In bright light, the bypass indicator LED can be hard to see unless it’s directly ahead. ?More than a few times, I have inadvertently bypassed the tuner while tuning. ?For something as critical as a bypass, it should have its own button.

I am actually thinking of redoing the front panel buttons and have them controlled by a Raspberry Pi Pico + relay board to enhance the tuner’s capabilities to run in my remote rig setup. ?Doing so would allow remote access to the tuner functions and eliminate human button pressing timing concerns for end users..?
