The HW-29 was first advertised in CQ magazine in April 1960. By November of 1960, Heath advertised the HW-29A and also an upgrade for the HW-29. Heath had used 5th overtone crystals in the HW-29 which had proved troublesome. For the HW-29A, they added a multiplier stage which required one addtional tube for doubling and tripling the commonly available 8 MHz surplus crystals to 6 meters.
