I have 2 FRS radios a 6500 and a 6700. I was just checking them both a couple of hours before the SARTG RTTY contest today.
A major problem, the radios will not transmit on RTTY.
Pushing the tune button on SSDR (no RTTY program running) to ensure they were working, I get no output, checking showing on the monitor, other modes the tune button works perfectly.such as Digi L, LSB etc (Dax is enabled for Digi L and RTTY).
Ideas please as I would have like to operate in the contest.

Do you have the Rcv DAX set to the same number: On Tx side is DAX on(blue)?
Also I operate RTTY using SSB and HRD ...No problem...

Please check the transmit Lo cut and Hi Cut filters settings in PHNE panel are set to allow the tones to get through.
Does the RTTY AFSK tones show up on the DAX panel TX stream?

GL in the test.
