The KW2000E was the final version of this popular Amateur transceiver with the last major update, introducing 500 kHz bands to remove the necessity for changing bands for the complete coverage of an amateur radio allocation that was more than 200 kHz wide.
Earlier versions of the KW2000:
KW2000 Launched in 1963, the original transceiver covered the HF ham bands in 200 kHz sections and had a PA using a single 6146 with a maximum input of 90 W PEP and 45 – 50 W PEP output.
KW2000A This introduced an updated styling and colour scheme with a dark blue-grey front panel. Technically it had an updated PA that utilised 2 by 6146 to give 180 W PEP DC input to the final RF amplifier. This would represent an output power of around 100 W PEP KW2000B
A version that was introduced around 1969. It incorporated a few updates to improve the performance including a new dual-speed drive that enabled more convenient tuning.
KW2000C This was a version that was intended for commercial usage and it had four crystal-controlled channels.
KW2000D
This was a digital development that provided for a digital readout, but it was never produced on a commercial basis.
