Alpha 99 HF Amplifier: This unit is nearly new and comes with original packing materials. It has been in dry storage for 20 years after its original owner became an SK. It has barely been used. Would prefer local pickup, but will ship at buyer’s expense via Pirateship. You won’t find an Alpha 99 in better condition than this one. Tested for full power out.

Elecraft KPA1500 display with WiFi: KPA1500 RF Power Monitor

See everything your KPA1500 is doing — at a glance. This plug-and-play OLED display connects to your amplifier's RS-232 port and shows forward power, reflected power, dissipated power, input drive, SWR, PA voltage, PA current, and heat sink temperature in real time. No modifications. No drivers. Just plug in and go.

The crisp 256×64 OLED display uses a clean 3×2 grid with proportional bar graphs and large, easy-to-read numerals — designed with older eyes in mind. Peak power is held for instant readability.

Bonus WiFi web interface — monitor and fully control your KPA1500 from any browser on your network. Change bands, switch antennas, tune the ATU, toggle Operate/Standby, and clear faults remotely. Works great with Tailscale for shack access from anywhere.

Built on the XIAO ESP32C6 with browser-based OTA firmware updates.
