Re: LA-1K Trips to Standby in SSB mode only

 

开云体育

I had similar problems two years ago talked with Mark at Palstar he had me put it into a dummy load everything worked normal the next day I replace my alpha DX plus antenna and today I use a hex beam for the higher frequencies and I use a double bazooka for 40 and 80. If you have a dummy load I suggest you try it out which will validate it’s from the coacts or the antenna

I have had similar issues. Like I said, look at all your other connections and antenna. GL

SWR is 1:1., using Palstar HF-auto tuner.
Only noticed it on 20 meters.
Does not trip to standby on other modes, on SSB
I replaced jumper coax between IC-7610, LA-1K and HF-auto
It's on voice peaks is when the amp trips out.
If I cut the mic audio back, it does not happen, however the amp puts out lower RF power.
I tried adjusting ALC on both the IC-7610 and LA-1K, there is no noticeable difference no matter what ALC setting I use.
