The HQ170(A) is a triple conversion receiver made specifically for amateur band use. It features an optional clock which can be set to turn on the receiver 30 minutes before it was needed in order to let the frequency stabilize.
The main tuning condenser appears to be an off-the -shelf component modified by Hammarlund by the removal of a rotor in each of the three sections. Flywheel tuning for smooth adjustment.
