The Johnson Viking II was probably the best HF transmitter for AM and CW ever made. It covers nearly all frequencies from 1.8 MC to 30 MC continuously. There was even the coveted CDC model Viking II that had no gaps in coverage, due to its intended use for Civil Defense stations. It is ideal for modern time CW operation on the WARC bands, assuming you have a crystal or feed the VFO input with the proper frequency. You can use the original Viking 122 VFO or a modern synthesized digital VFO for wider frequency coverage.
It employs WW2 surplus parts and is built like a brick outhouse. It does not use some cheesy pi network inter stage coupling network. It is all parallel tuned. This avoids subharmonic problems. It has been popular for use as a Pirate Radio Transmitter, but it sounds terrible with the stock audio. I believe that this transmitter is better than the Valiant because it has a roller inductor in the final and unlike the Valiant, the transmitter and VFO cabinets are copper plated and well shielded for RFI.
