In accordance with your 14-Dec-2023 post /g/la1k/message/1488 the LA-1K in question started to work just fine, after you found the PTT phone plug on your transceiver came undone when swapping out the old amp.

Given a LA-1K SWR readout of 1.2:1, I'd think it's operating on the same antenna system that was connected to your old amp.? If your old amp was also showing a SWR readout of roughly 1.2:1 and had an acceptable RF output on the same frequency range on 15m, then there is a good chance your new LA-1K isn't fully serviceable.

If you haven't already done so, you will want to contact Palstar soonest for any repair actions, as necessary, especially if your LA-1K is purchased brand new from one of their authorized dealers that might have the unit sitting on the shelf for months; reasons as follows:

1.? Mr. Mark Ward (Palstar techician) advised me in writing the LA-1K warranty is only for a period of 12 months from the date of manufacture.
2.? Mr. Ward also advised me in writing that other than Palstar, one cannot derive the date of manufacture of a given LA-1K from its serial number.

Hope your LA-1K is in fact fully serviceable, and the root cause is something real simple like the last time when it was just a cable came undone.

73 and Happy New Year!
