KPA500 RF Power Monitor +: KPA500 RF Power Monitor+

See what your amplifier is doing from across the shack.

The display puts power, SWR, voltage, current, temperature, and band on a bright 256x64 OLED you can read from your operating position. It plugs into your KPA500's RS-232 port. No modification to the amplifier, no software to install, no cloud account.

Join it to your WiFi and the same readings appear in any browser on your network. You can switch bands, set fan speed and toggle operate or standby right from the page. Add Tailscale and your amp is on the screen from anywhere you travel.

The OLED keeps working whether or not WiFi is connected, so you are never waiting on your network to see your amplifier.

Firmware updates install over the air in your browser.

Alpha 9500 HF Amplifier: There is no better amplifier in the world than an Alpha 9500.
It loafs at the legal limit, it lets you combine antennas for a supercharged receive signal, it supports up to 4 antennas, has a built in Autotuner, and uses a widely available 8877 ceramic triode. The build quality is off the charts, it looks fantastic in a rack, and the list goes on.
This AM I fired it up with a 56W tuning signal from a Flex 6600 and got 1646W output without going anywhere near Pmax input.
The unit is in excellent cosmetic condition and works as it should.
Just $4599 plus $161 shipping CONUS.; Listing #1779242 - Submitted on 09/12/26 by Callsign K1FIE, Modified on 09/13/26 - IP: 2603:3006:e02:e900:7c85:65b5:76ff:4af5; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

Henry 8k Ultra mint: Well I’ve decided to sell one of my 8k Ultra amplifiers. I can send pics and a video. I have 2 of these. My opinion is the best amp ever made. I’m only selling because I’m outta room in the shack. Clearing some space and de cluttering. $9500 I’m not interested in any low offers. Cash $$ might take a couple items in trade. But whatever it is needs to be clean and working 100% just like my amp. This isn’t an easy amp to let go of but I need to make some room. The 3000 tube is 100% this amp is hardly used.; Listing #1777599 - Submitted on 08/26/26 by Callsign KC5TJT, Modified on 09/12/26 - IP: 216-21-174-42.mci.googlefiber.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
