A transmit converter (and amplifier) for 630 and 2200 meters


KA7OEI has a great write-up on building a transmit converter for 630 and 2200 meters:

As the name implies, a transmit converter takes another frequency – such as that produced by a conventional HF transceiver – and converts it to another frequency.  In my case I use an FT-817 – a low-power (5 watt) all-mode, all-band transceiver that is a favorite for VHF, UHF and microwave enthusiasts that use transverters.  Because of its small size, feature set and already-low output power, it is a natural to be used in this application.
