I use a GPSDO as my lab standard and as the reference for my Freq Counters. I have another "Box" I picked up that will accept a 10 MHz signal from my GPSDO and provide frequencies at 72.5, 725 and 7,975 MHz that are locked to the GPSDO. After sufficient warm-up I was surprised to see the FA-2

There have been some Trimble Thunderbolts over on that auction site that were being sold for $80 each (not surplus Telcom ones). I grabbed two and they work. My antenna was a "hockey puck" style antenna sitting on the window sash, facing South. 73, Dick, W1KSZ Sent from
