Thanks for the alert on the K5CM Frequency Measuring Test a few nights ago.
That test uses two stations to send a CW carrier on 160, 80 (twice) and 40 meters. A FMT is something totally new to me. My only preparation was to calibrate the radio carefully against WWV using its built-in scope. My receiver was in the DSB mode. I used the scope to guess-timate the frequency to an additional decimal point. Few entrants use a radio alone. Many have costly GPS based frequency calibration sources or the like and complex schemes to interpret the frequency. Experience counts. So does speed, since you only have three minutes to come to a conclusion. In other words, my entry wouldn't threaten the experts who come within one or two MILLI-hertz. But my stock Flex did very well. Three of my four readings were within 1/2 Hz. On 40 meters I was off by .96 Hz. QRN on 40 made the weak signal difficult to read on the scope. Still, accuracy was better than .25 PPM on each reading, well within Flex specs. Anyone else participate?
