KeychainQRP, the worlds smallest HF ham radio transmitter

[KH2SR]

I thought a few of you QRP operators out there might be interested to hear about my little KeychainQRP project.

They are tiny QRPp CW HF transmitters that you can keep on your car keys, use for ultralight SOTA activations, just for having fun practicing code with your ham friends.

The HF band options currently available are 10m, 15m, 17m, 20m, 80m, & 160m.

RF Power Output: 160 Milliwatts
Antenna Connector: SMA female
Power Supply: 9 volts
