Rich, interesting to see others having same issues as i am. Just operating in the cqwpx cw contest this weekend and mines doing it randomly on CW. Its a real pain to be baby sitting this amp. I may

To summarize results for future reference: 1. A PolyPhaser surge suppressor (Model IS-50UX-C0, 2kW) was determined to be incompatible with my Palstar LA-1K / Palstar HF-AUTO installation likely due

Thanks, that makes me feel better about the “pill”s I have. Bill Grover, N3EYF Sent: Thursday, May 28, 2020 10:41 PM To: [email protected] Subject: Re: [la1k] Resolved - Curious LA-1K

Yes-the “pill”(as Alpha Delta calls the gas tube arrestor) is installed in the switch. Bill Pfost wpfost@...

Including the arrestor I'm assuming. Bill, N3EYF

So far, the Alpha Delta Coax Switch works great with the LA-1K.

For what its worth. I had nothing but issues with the rf detection in normal mode. Im using an ftdx5000. Once i went direct, all my issues have disappeared. Without a dummy load even. All modes. All

I use one. It works fine. Sent: Thursday, May 28, 2020 7:06 AM To: [email protected] Subject: Re: [la1k] Resolved - Curious LA-1K Shutdown Problem I'm considering the use of an Alpha Delta Coax

Just putting this in here for anyone else with a TS-590SG (likely any radio that will provide band data). I initially was running with only the PTT cable and using RF for band switching. The Kenwood

I'm considering the use of an Alpha Delta Coax Switch to ground the line when not in use.? That switch may be operated without the gas tube (AD calls it a "pill").? I can test to see if the pill

Bill: Don't forget to terminate the line with a short to protect the line from being damaged by high voltage during a strike. Also, if you disconnect a transmission line inside of your house, be

Further investigation shows that any surge suppressor in the transmission line of my non-resonant antenna is not likely to work.? I am left with the direct grounding of my CWSByteMark 9:1 balun (

My LA-1K was updated by Palstar to current production improvements.? The improvements were discrete component changes and replacement of three low-pass filters.? The amp was also checked for

Did you try it with the Alpha Delta alone? What happened? Bill, N3EYF

Bill, Currently using Morgan HF arrestors on my two HF antennas (non resonant) and no issues with Palstar amp or tuner. Might be worth a look. Your mileage may vary. Brian (W0BSF)

My LA-1K was flawless into my dummy load.? It was flawless into the dummy load attached to the HF-AUTO tuner.? When I connected my non-resonant dipole to the HF-AUTO and tried to operate my LA-1K,

I had nothing but bypass issues with the rf detection on all bands all modes. I recently went direct and it resolved all my bypass issues. Even with cw. It stays put now. Yes, i noticed the amp will
