Do you like LASERS?
This is my experiments with a Helium-Neon LASER Power Supply for use with a Melles Griot 1mW gas LASER tube.

Linear Power Supply Astron VS-20M. The D-104 microphone from my CB days. And a vintage brass straight key limits my speed to 10 WPM, is about what I can copy.
Only in 2023, did I create a Facebook page.

Just started (in 2022-10) my renewed interest in the HF bands. I've never been much of a talker.
Using a newly raised 40 Metre EFHW with homemade 56:1 transformer.
Power supply limits my output to 50-75 Watts PEP.
