RF DRIVER

[StanStan]

I'm looking for someone with experience in fpga design to construct a rf logic pulsing circuit to send digital signals via shortwave antenna.
It's an inductance matching signal type from tuned coil to tuned coil.

To transmit anywhere in the short wave band (other than when using legal CB equipment), you need a government-issued licence for whatever country you are in.

The item in the photo looks like the loading coil at the base of a CB antenna; those just allow a physically shorter antenna, rather than it being a full 1/4 wave tall.

CB frequencies are only legal using type-approved transmitters.

I'm not sure if "Packet radio" is legal using CB transceivers? That's a system which has been around for decades, using a device that connects between a computer or terminal and the audio connections on a transceiver.
