[time-nuts] Frequency standard

[Bob Albert]

 Well Ian there are lots of guys on nets using archaic equipment.  I go to some of their swap meets.  I have repaired, built, and salvaged many of those old items.  Of course back then the 1 kHz resolution of Collins gear was amazing.  I built a frequency meter a while back.  An interesting design inspired by GE Ham News.  It utilized a VFO that would tune from 100 kHz to 110 kHz I think.  The harmonics would, after a while, overlap so the entire tuning range was covered by about 25 turns of a vernier dial.  I could resolve much less than 1 kHz and it was very accurate.
I still have a BC-221T that is almost pristine and works great.  Back in the day I also had an HP 524 counter but not until I got some use out of a Beckman unit for which I built a 10 MHz counting module.
I have always enjoyed measurments, and I feel fortunate that I can do the things I do.  I just repaired the test leads on my GR 1658 bridge, and am in the process of learning to use a couple of VNAs I recently acquired.
Unfortunately I am an old man and don't know how much time I have left.  But I do plan to make the most of it.

  Bob,

  Frequency counters are practically redundant these days. Ovens and GPS make transmitting accurate.
I don't go to the bands' edges, and the timing in the radios is fine, even back to my IC-735 and
  Eddystone EA12, from G3YTO, sadly dead long ago.

    Ten or twelve digit frequency measuring is just a game mostly for a lot of us here.
