Brand new LA1K.? Current firmware.? To keep it simple, we will go with the dummy load first.
I will copy/paste his reports to me.? If ANYONE has a clue, please let me know.? He bought the LA1K at my suggestion, and things are not going well.
. ?I did try the ANT switching to 2 to 3 and back to 1.
And I did remove the band cable
In STBY mode it senses the correct frequency and changes band accordingly. ?I am set to 20 meters CW to a dummy load. ?10 watts. ?When I switch to OPR the amp shows the correct frequency 14040 but switches to 160 meters and then goes into bypass. ?I have no idea what is going on ... ?Then I switch to STBY and hit the key and the amp goes to 20 meters like it should. ?I can repeat the cycle.
I am not using ALC as that has no effect on CW.
. ?I did put a meter on my outlet and it shows 250V across the top two and 125V between either top ?and common.
. ?Also swapped out the coax to the dummy load, no change in behavior. ?I note that in STBY the frequency is correct and stable, while in OPR the frequency is correct but flashing.
On to the antennas (which work fine with an Alpha amp)
I did try it with a real antenna. ?Seems to work fine on the big 8040 vertical ( has a line isolator but no arrestor ). ?When I switched to the LPDA ( with arrestor ) it worked on 12 meters briefly, then went into BYPASS SWR. ?First time I have actually seen the BYPASS SWR on the display. ?Previously it was just showing BYPASS but not the BYPASS SWR. ?And now ( when operating properly ) the frequency is not flashing, so maybe frequency flashing is a clue.
Now I know and understand even less than I did before. ?Was on 40 meter CW, answered a CQ from F4DIA on 7008. ?Was running 800 watts to the 8040 vertical, SWR 1.3
?
Halfway through the QSO the amp kicks out, showing high SWR. ?Had to finish the QSO barefoot.
?
Went back to dummy load. ?900 watts CW 80 meters. ?SWR 1.0 ?Amp works, then goes into BYPASS with no BYPASS XXX but I don't have to reset it, just key again and it okay. ?Disconnected band cable ( again ) and no difference in behavior. ?It just keeps going into bypass ( flashing yellow BYPASS ) no BYPASS XXX just flashing BYPASS and flashing frequency when I key.
ANYONE????????????????
