The HT-32A added push-to-talk operation, as well as provision for phone patching and RTTY, to the HT-32’s specs. There is little to distinguish them cosmetically.
The HT-32B was the final model of the HT-32 series. Changes from the HT-32A were largely cosmetic, with the styling more closely matching the SX-115 receiver. In addition to SSB and CW, it transmitted AM with both sidebands.
