 A low power 3.5MHz ARDF transmitter
 This low power transmitter is developed for ARDF exercising purposes but of course can be used as super QRP transmitter either. With 1 or 2 meter wire as antenna and a ARDF receiver with ferriterod antenna the range is about 100m but with better antennas and a 'real' receiver the range is probably much larger.
