Hi Jack what is your frequency reference for these measurements?

 

I have just finished testing my IC-725 dial set to 10.15102MHz was infect
receiving on 1015100 LSB Then measured the transmitter and found it was
transmitting with the dial still at 10.15102 MHz gave a transmit frequency
of 10.15098 MHz. The TX measurement needs better gear as I had to use a
second receiver checked as the first then compared the transmitter with the
received signal. Will borrow a counter from work and do a better measurement
next week.

 

I believe these tests as I was using an HP 8648A locked to my GPS based 10
MHz reference this set up will resolve well bellow an Hz.
