Hammarlund HQ-180 CW/AM/SSB Receiver

This Hammarlund HQ-180 belonged to Milt Moratis W3XX. K3MSB completed the resoration in the fall of 2003. Alignment of an HQ-180 is much nicer than aligning an HQ-170, as the 180 has both main tuning and band spread directly connected to their respective tuning capacitors. In August 2009, the HQ-180 was given to Joe Roth WC4R.
