[time-nuts] Vintage Frequency Measurement

[Tom Van Baak]

> More recently, Alan Melia, G3NYK, reports an accuracy of 0.1 Hertz using
> the same technique, http://www.alan.melia.btinternet.co.uk/freqmeas.htm .

John -- Alan's web site moved from btinternet to http://g3nyk.ham-radio-op.net/ so the new URL is:

  "Frequency and Time Measurement"
  http://g3nyk.ham-radio-op.net/freqmeas.htm

List -- it's worth a look at that page. Not just the BC-221, but a nice combination of history & technology, photos & diagrams, and long list of references.
