Grayson said quite a lot in this short 4 minute interview: <\/b><\/div>\n

<\/b><\/div>\n
— 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\/ <\/a><\/b><\/div>\n

<\/b><\/div>\n
— 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:<\/b><\/div>\n

<\/b><\/div>\n
— 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. <\/b><\/div>\n

Here are Grayson’s Technical Documents (a real treasure trove): https:\/\/kj7um.wordpress.com\/<\/a><\/b><\/div>\n

Three cheers for Grayson. And thanks to Bob Crane W8SX for doing this interview. <\/b><\/div>\n
