HW-100


The HW-100 80...10 meter Ham Band Transceiver came on the market in 1968 and was produced until 1971. It was then replaced by the HW-101. The HW-100 had the look and feel of the Single Banders HW-12A/HW-22A/HW-32A but under the hood it was a somewhat simplified SB-101. The SB-101 was too expensive to many Radio Amateurs so the Heath Company derived the HW-100 from the SB-100/SB-101 series to meet the demand from the Radio Amateurs of a cheaper transceiver. They made it possible by using a new VFO with a much simpler dialing mechanism and readout having 5kHz resolution instead of the SB-101 1kHz resolution. Further more they reduced the number of facilities on the front panel and the metering. Also the casing was simpler. The HW-100 was quite successful but many complained about the fuzzy dialing mechanism. The HW-100 had only an SSB-filter but it was possible to mout a CW-filter afterwards.

When I bought this HW-100 it was in a bad condition. But after cleaning all the circuit boards, tubes, etc., replacing the drive belts, repairing the 28MHz coil in the Heterodyne Oscillator, repainting the casing and making a total re-alignment of the HW-100 it turned out to be a very nice transceiver. Modifications that I plan to do is installing a CW-filter and a variable audio filter for better selectivity at reception.
