If you haven’t already joined “HamFest365” on Facebook, take a look today.  This FB page is filled with amazing radios, many of which are for sale.  It is a site with many pictures of vintage gear, much of which is seldom seen.

The site was established in January of 2017 by Elizabeth Wilson, K4GHT.  The group page already has over 275 followers.  HamFest365 is a one-of-kind tribute to the sale of vintage radio gear, amateur, commercial, military and homebrew – open to all for the purpose of selling equipment.

Here’s an example:

The front panel and VFO cover silkscreen and paint are completed. (Thanks to Chuck Hurley) Super nice work Chuck!
Knobs are buffed out. pointers are repainted.
The electrical work is done. Lastly I am masking off the transformers and going to give them a shot of gloss black.
This one is a gem.

Been two years since I started this one. I guess the move didn’t help. It was nice to have a week off to enjoy the new work bench and play radio. The valiant project should be completed & on the air by the end of August.

Thanks to all the restorers in the group for inspiration over the past 10 years. Dr Harlin, Stan, Adrian…….When I look back at my first one (ranger 1)
I picked up a few skills along the way.

What a great hobby!
PS 3885 is a winner.
