Episode 086 - Grayson Evans - TA2ZGE/KJ7UM
If you wanted to homebrew QRP radios with vacuum tubes, or "thermatrons", then the go to guy would be Grayson Evans, TA2ZGE, author of the book, Hollow State Devices, the primer that he always wanted to read, but had to write himself. Grayson joins Eric, 4Z1UG, to discuss his ham radio life, "thermatrons", home brewing, and operating QRP, from his QTH in Ankara, Turkey.
