Default "New" HQ-145 on the air!

My HQ145 performs beautifully also, repaired by Paul at Antique radio
Consignment center in St Paul MN. Just one question: On broadcast band
sensitivity is fine until you go below 1000KHz. Then, very insensitive.
Any ideas?
Thanks, Tom


If you are really losing sensitivity on one band here's a few
things to look for:

1: Open antenna coil winding on the first RF coil for the BCB.
Even open, there is enough stray capacitive coupling to provide
somewhat of a match at the high end of the band; but
not enough at the low end.

2: Bad alignment on that band; the LO and RF stages are not
tracking each other across the full tuning range.

I'd be asking Paul why his repairs aren't up to snuff myself.
