Hammarlund HQ series: A digital display modification

HQ-DisplayMany thanks to SWLing Post reader, Jeff (KB7AIL), who shares the following:

Saw the article on the DC meter in a Hammerlund HQ180.

Another mod I have seen is replacing the meter with a digital display.

It integrates with the HQ180 nicely.

They also have digi-displays in cases or use with other receivers/transceivers.

Very cool, Jeff. While I know a digital display might kill the vintage look for some enthusiasts, I have to admire such a useful modification to replace a broken Hammarlund clock/meter.

As Jeff mentions, Electronic Specialty Products has a number of external digital display boxes as well. Check out their full line of products on the ESP website.

    Hello sir,
    it would be highly recommended if your posting shows a date. That would be very helpful.
    In this case, all the links are going to the Nirwana because they were very very very old and does not exist any more in 2023.
    Thanks a lot, best regards,
    Steff

    Great idea. I like the repro H-meter logo. I was running a Hammarlund SP-600 JX-21 last evening (with a 10′ Jensen speaker). My SP has the optional Hammarlund XC-100, a 100 kHz crystal calibrator made from 1956-196? that could also be installed on the HQ series receivers. It’s a very nice tuning aid.
