[Hammarlund] HQ-150 question

[Murray, Conard]

I see the HQ-150 is single conversion, so having some image at 15 MHz isn't that big a surprise. I suspect the front end tracking is a bit off on the high end of that band. I would try retuning the front end by adjusting the capacitors to peak WWV at 15 MHz and the inductors on WWV at 10 MHz. I know from experience that is easy to grab the wrong peak when doing a realignment on the high frequency portions of these receivers.
Good Luck and 73,
