Did you calibrate your LA1K power meter against a known calibrated watt meter?? Was the SWR between your DX101D and your LA1K exactly 50 ohms with no reflections?? Were you using a dummy load for your test??? My LA1K matches my exciter perfectly, as does the meter following it on the HF-AUTO.?

Hello Dave N5DDD,
Sounded like you were referring to my 5-Apr-2023 post
/g/la1k/message/1184 when asking those three (3) questions.
I was putting together an antenna system (antenna + feed line; a store-bought 50-ohm coax with PL-259 on both ends) for the 6-meter band earlier this year.? My Rig Expert AA-55 Zoom indicating 1.28:1 on 50.125 MHz for the antenna system in question.
Next, hooked the antenna system to the LA-1K then drove it with my FTDX101D.?
No dummy load; it wasn't a test.? I shared my observations, documented with the video clip, with Mr. Mark Ward (Palstar technician) who advised me to ship my brand new LA-1K bought directly from Palstar (delivered late January 2023) for calibration, if I would like to do so.
Since I had already decided to purchase the Elecraft KPA1500 Amplifier at that point, I simply kept my LA-1K as is (yes, didn't even replace the 2nd replacement power switch that Palstar sent me) sitting next to my KPA1500/FTDX101D combo, as seen on my QRZ page more or less a static display! lol
The same 6-meter antenna system is working just fine with my KPA1500/FTDX101D combo.
