Are you sure you have your cabling correct? ?
If there is a PTT line in the interface cable coming from the 7300, it must be connected to pin 7 (Amp Key In) of the amp's XCVR Interface jack. ?
If that is the case, then you neither need nor can you use a separate line to the PTT jack on the rear of the LA-1K. ?You must have one or the other PTT lines, but you can't have both connected at the same time.
If you want the amp to follow 7300 band changes, then the?band-data line coming from the 7300 must be connected to pin 5 of the amp's interface jack.
When tuning the HF-AUTO, make sure the amp is in STNBY and use only 15-25 watts (misprints in the manual suggesting higher) of AM, FM, or RTTY. ?After one shot of RF finds an initial match, it takes a second shot of RF to complete the solution. ? After a good match, put the amp in OPR to operate.
For CW, use only the amp's DIRECT KEYING mode, not NORMAL mode which truncates the first character.

I just set up the radio desk with a 2022 LA-1K and HF-Auto both purchased used, pristine. This was 2 months ago.
I connected?to the IC-7300 via the 13pin plug and the PTT RCA connector?on the amp. It wont key up to TX mode, I tried the IC-7300 on RTTY with 30-50W. The?meter sees the?power so does?the tuner.
I then shorted the PTT connector on the amp to ground hoping to hear the click to TX, nothing.
I tried both modes selectable on the screen, nothing.
I tried with the gray button (on the front) both in and out, nothing helped. BTW, I cant?find any mention of that button anywhere. Whats it for?
I wrote a message to Palstar but I figure it will take a week for a reply.?
Looks like a fantastic amplifier?and I cant?wait to start using it. The HF Auto is working fine.
Anyone out there know whats?going on? I hope its my mistake not a defect. The user manual sure needs to be a lot better.
