1930's One Tube TNT Transmitter - CW with captions

Harry surprised us on Thursday with a one-tube transmitter. It's not often that we hear one of these old TNT circuits sounding so nice - free of chirp - but we know how skilled Joe, K8LKC/SK was in understanding and constructing replicas of radios from yesteryear.

Wow Lynn, you did an amazing job of detailing that QSO with the photos and scroll print. It was great to be able hear what the TNT sounded like 100 miles to the W/SW. Of course, coming through on 3560kcs at 14:00Z is a propagation gift at times. Ant: 80M dipole w/ladder line @ 70 & 50 feet.
