Title: WANTED: HQ-180 Schematics Post by: W1KSZ on May 20, 2017, 04:02:22 PM I found in my stash an ancient original manual for the HQ-180 Series Receivers (HQ-180, 180A, 180AX and 180EX). AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
I scanned all 111 pages but the schematics are in terrible shape. Most on-line schematics are no better. What I need is original schematics for the 4 varieties, they must be clean and be able to reproduce. I will offer a copy of the scanned manual to anyone who can supply a decent schematic of any or all 4 varieties. My scan copy also includes addendums for the IF Noise Immunizer, Fixed Freq Mod and a few others. Tnx, Dick, W1KSZ |
