...I just noticed your YX and I am XY...what are the odds ? ...you have been a great help... for the current time I'm going to move ahead with Plan B...I,m making this up as I go, but I am 99% CW so this may make it easier...so one of the drawbacks of the r75 transceive mode is that the freq's are locked together, so if the dx station is calling , 'up 1' then I have a problem...but as separate radios I can move in any direction any time...and with both radios having stable digital readouts I can get really close very quickly and if I have tested the freq readout differential I should be very close...so that is Plan B for the current time...I have not tried this yet...and if this does not work, go to plan C ...which is turn on the ic7300 or ftdx10 andwork 'em that way and quit driving myself crazy ! ...thank you for your patience...
