The Heathkit HW-7 was the first QRP transceiver offered by Heathkit. It was available from 1972 through 1975. The HW-7 provided coverage of 40, 20, 15 meter bands. The transceiver featured a very simple direct-conversion receiver design and this simple design led to performance problems including sometimes-severe broadcast-band interference, microphonics, and AC hum. According to the January, ARRL review (January, 1973), the original price of the HW-7 was about USD 70.
