Hammarlund Four-20 CW Transmitter

Simple, unmodified crystal controlled twenty-watt CW transmitter. Front panel controls for the four ham bands: 80, 40 20 and 10 meters. Crystal socket on the back for easy frequency changes. One coil included. There are connections brought out to the back of the radio for an accessory modulator so you can talk AM. If you insist. One type 807 does the amplification and is rated at 25 watts plate dissipation. The bottom cover is missing and this is an easy piece to have sheared off at the local sheet metal house.
