Greetings. My LA-1K is for sale, see attached photos. I am asking $2500 USD for the amplifier. Clean no smoking environment. In discussion with the Palstar Tech, the 10 dB input attenuator was changed to a 6dB attenuator allowing full output when driven by a SunSDR2 Pro, 15 to 20 watt output SDR transceiver. The photo shows approx 1 KW output on 20m at about 24 watts drive from my Elecraft K3s. Appox 38 amps as recommended limit. I will be in Dayton for the Hamvention, no shipping! Thanks for your consideration. 73, Roger VA1RST VE1-VE0 QSL Bureau Manager

Good news to share: My LA – 1K amplifier was sending no power out and was not band switching as it had previously done successfully for months. I replaced the Palstar LA-1K to yaesu band data radio interface cable, and my LA-1K amplifier is again fully functional. Bill AG5ZN

Hello Everyone I will be picking up my new LA-1K sometime early in December. A few questions for current owners. I presently have a dedicated 120 V line into my shack, with a 15 amp breaker. For years I ran an Ameritron AL-80A on this circuit, up to 800+ watts at tines with no issues. So I am wondering if the LA-1K will be fine at reduced power output (700-800 watts PEP on SSB) on that same circuit. I will eventually get around to running 220 into the shack once I pick up some wire etc etc. But for now I would like to run it off the 120 V line. Does anyone foresee any problems with that? Thanks, 73, Rick VE3PP

To sum things up... As stated in Ray's post https://groups.io/g/la1k/message/1261 an SWR as high as 2:1 is acceptable, and yet Paul (NO0T) observed that his LA-1K went to bypass as SWR went to 2:1 to protect the finals. This clearly demonstrated yet another case of *inferior design implementation* found on the LA-1K amplifier. In his defense of the LA-1K, Kent (K9ZTV) writing, in part, "My Elecraft KPA500 folds back to half-output at 2:1 and goes into the red zone (cautioned as "critical" in the manual) above 2:1." in his post https://groups.io/g/la1k/message/1262 yesterday. But, the KPA500 Owner's Manual: https://ftp.elecraft.com/KPA/Manuals%20Downloads/E740150%20KPA500%20Owner's%20Manual%20Rev%20E1.pdf states, in part, on Page 35 " For ease in reading the critical SWR levels, t he SWR LEDs are green from 1 to 1.5. The 1.5 to 2.1 SWR LEDs are yellow and the LEDs for SWR s above 2.1 are red." It is *important to note* Elecraft stating that " LEDs for SWR s *above 2.1 are red* " as opposed to " goes into *the red zone* (cautioned as "critical" in the manual) *above 2:1* " as Kent observed in his Elecraft KPA500. In an attempt to obtain clarifications from Kent in my post https://groups.io/g/la1k/message/1264 yesterday, of which I haven't received a response as of this writing, I had amended it to point out that the Owner's Manual of the Elecraft KPA1500 (their top-of-the-line amp/ATU machine) states " SWR bargraph: The SWR LEDs are green from 1 to 1.5. The 1.5 to 2 LEDs are yellow and the LEDs above 2 are red" and " The bargraphs are color-coded green for normal, yellow for marginal and red for excessive levels. Excessive levels may trigger a fault and switch the KPA1500 to STBY" on Page 18 and Page 27, respectively. It is *important to note* the Elecraft KPA1500 may trigger a fault and *switch to STBY* if and only if it encounters excessive levels ( *above 2:1* ) of SWR. An SWR *as high as 2:1* is acceptable for the Elecraft KPA1500. SWR reference material for all to consider: https://www.arrl.org/files/file/Technology/tis/info/pdf/q1106037.pdf 73, Ray KJ5MI
