[time-nuts] Frequency standard

[paul swed]

Bob
The gpsdos will be far superior to the method you are currently using. I
will guess 100-1000 times better and higher. I took a quick look at EBAY
boy there are lot of them these days. We all have our favorites. Trimbles,
HPs... But what would help is understanding your need. What do you want to
accomplish.
