HF regenerative receiver demonstration

A demonstration of an HF regenerative receiver tuning the 10 MHz (31 metre) shortwave broadcast band.

Despite the large case the set here is solid state. It uses MPF102 FETs for the RF preamp and detector and an LM386 (or similar) for the AF amplifier.

A wire antenna was used and conditions were poor at the time this video was taken (late morning).

Yes, it's a vernier dial.

Any SSB receiver, particularly one that covers several megahertz in a 180 degree dial turn will be critical to tune.

Hence vernier dials are used for both the main tuning and the fine tuning.

The meter is not used for much. Only for battery voltage when a switch is pressed.

Very nice cabinet construction. Excellent front panel layout; It looks great.

I'm going to have to build one these using one of "More QRP Power" designs. Also, I enjoy your videos for 1/4 wave vertical antennas. Very helpful. Thanks for the videos.

Ya got my curiosity m8! I may look into getting a Ten Tec rig.

Interesting, I'm thinking of doing a regen receiver. It seems critical to tune, is that a vernier drive on the left? Also what is the meter for? (I didn't see it move, is it signal strength?).
