I've been working CW with the R4C and T4XC as 'separates' until now.??
Today, tried something different:? Letting the R4C control both radios.. I found that I can spot the other station at around 550 Hz (haven't measured yet) and we're both dead-on.... no chasing each other up or down the band.? 500-550 may be low for some ears but worked for me.
