The very first HRO -- the 1933 engineering prototype!

A nostalgic photo of the 1934 HRO "Senior" -- thousands of which are still in use all over the world.

The HRO "Junior" -- a lower-priced version of the HRO without crystal filter or S-meter.

1933 -- The first amateur transceiver -- the 5 meter model TRW. Notice the light weight mobile antenna mounted on the bumper of the Buick.
