THE AM'ers

A receiver built by VK2AHJ in the 1950's

 

A 6L6G

If I have to explain the significance of this glowing 6L6G, then, my friend, you will never understand!

It may surprise many just how much AM is still used on our ham bands. Here is a net which has been operating for many years which you may like to check out or even check in. We have some wonderful, old, high level plate and screen modulated, classic valve radios in operation, some home brew gear, old military equipment and even the occasional appearance of a modern solid state transceiver. This is where one can listen to the rich sound of that golden era that preceded the popularity of SSB on the ham bands.

I was unable to extract a photo of Bob VK2AVQ but I do have some photos of the gear he has been using on AM. It is a lovely rack made by George VK2AHJ in the 1950's. Here is the transmitter as it is today after restoration by Bob (top photo) and as it was cc 1950's with the builder, George VK2AHJ (bottom photo).
