This is my Hammarlund HQ-180 receiver. It is pretty clean, and works well. I
added an additional hidden regulator for 150V lines. I also had to remove the
AGC from the 6BE6 455kHz to 50kHz mixer because the AGC would pull the
oscillator causing frequency change as AGC changed. This has to do with the
Vernier Tuning system.
