It has a nominal output power of 100 watts into a 50 Ohm load. The KWM-2 has a duty cycle of 100% for SSB and 50% for CW. The KWM-2 consists of a double conversion receiver and a double conversion transmitter. The transmitter and receiver circuits use the same common oscillators, mechanical filter, and RF amplifier. The transmitter low frequency IF and the receiver low frequency IF is 455 kc. The high frequency IF for both is 2.955 to 3.155 mc. This is a band pass IF which accommodates the full 200kc bandwidth.
The KWM-2 can be operated on any frequency in the range of 3.4 to 30 mc, except 5 to 6.5 mc, by installing the appropriate crystals. The KWM-2 comes equipped with crystal sockets, crystals and bandswitch positions for eleven 200 kc bands. Crystal sockets and bandswitch position also are provided for two additional 200 kc bands between 28 mc and 30 mc.
The front panel controls are as follows, an OFF/ON/NB/CAL SWITCH, EXCITER TUNING, ZERO SET, PA TUNING, LOADING, MIC GAIN, BAND SWITCH, AF GAIN, RF GAIN, EMISSION and METER SWITCH.
