LISTEN TO THE INTERVIEW HERE:
Grayson said quite a lot in this short 4 minute interview:
-- At FDIM he was selling his wonderful book "Hollow State Design for the Radio Amateur." Buy one here: https://www.ermag.com/product-category/books/
-- Grayson was also selling a Thermatron version of our beloved Michigan Mighty Mite transmitter. It is crystal controlled for the 40 meter band, but the Color Burst Liberation Army approves! Here is a wonderful video on this rig:
And be sure to watch Grayson's excellent course on Thermatron Homebrewing:
-- Asked why someone should build with tubes when so much good solid state stuff is available, Grayson makes some especially excellent points: The solid state gear is often filled with mysterious little black boxes -- we often don't really know what goes on in there. Thermatron construction provides a break from complicated SDR nonsense "that is not really radio." That last comment will generate some criticism, but not from here. I think Grayson is right, He earlier expressed admiration for complex circuitry, but he also rightly defends simple, understandable rigs.
Here are Grayson's Technical Documents (a real treasure trove): https://kj7um.wordpress.com/
Three cheers for Grayson. And thanks to Bob Crane W8SX for doing this interview.
