These transmitters have performed extremely well over the years, with no component failures or downtime since they were built in 1985. They have been used portable on camping and vacation trips , driving a variety of antennas often with less than perfect VSWR loads. They are intended to provide a clean keyed CW signal on 80,40 or 30 meters of 12-20 watts output from +12-+13.8 VDC. The latest Revision 7, makes changes to improve VFO Stability.
