AS-1289 broken?
(1/1)
CalleQ:
Is the antenna switch AS-1289 broken when it suddenly raises the swr high and the linear amplifier goes into swr protection? If I bypass the shifter, this doesn't happen.
sm2o:
Have you tried in manual mode. It may be HF which disturb the data connection which cause it to switch to wrong band or no antenna. Also set "Unknown frequency=relays off to NO, which prevents it from switching if the fq info is totaly corrupt.

Ok, thanks for the reply. I guess I just found it. One UHF body connector of the device was loose. I tightened it and now it seems to stay on.
