My S-20r and S-40A? have flywheels on the band spread. It's possible that some receivers have flywheels on the main tuning but I can't think of any hallicrafters that? do. Also, flywheels are found on some direct drive dials, not just strring drive.?
? An interesting? i think flywheels were more more sales gimmicks than practical? devices.

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?
