Actually, the transmissions seem stable enough over time that I haven't
noticed any real difference in frequency over the 15 minute span. I've
basically worked with the best chunk of signal I can find during the period.
To be honest, the greatest weak point in the test has been ARRL's
measurement system. Many of us believe that last year they mis-measured
the 160M signal by about 0.4 Hz, due probably to interference from the
other transmissions as they were measuring the signal off the air into a
counter, and not from a direct tap into the antenna line.
