The HQ-129-X is done, as good as I can get it. It is receiving well on all bands. The crystal filter works like a champ now, suppressing adjacent noise from the desired station. Even on the AM broadcast band, if one just uses the first notch it greatly improves the reception and signal to background noise. All in all I am quite pleased. Sadly, the signal strength meter does not work. I have tried and tried to get it to work, but to no avail. Finally I measured to see if it is open, and it is... infinite ohms. C'est la vie ! Other than that this is a great old radio receiver.
