Here's a question
that is of general interest to me.? What was the first and last
Hallicrafters radio (Receiver or Transceiver) that had a flywheel
incorporated into the main frequency tuning?? I do recall in High
school our SX-28 indeed had it.? My SX-115 has it (matching HT-32B
too).? Did any of the SR series transceivers or later SX-receivers
have a flywheel hidden inside?
