[Elecraft] [K3] Using DTFM microphones

[David G4DMP]

I would be pleased to hear from anyone who has had success in using
either the Kenwood MC-59DM or the Icom HM-98S mics on the K3.

I am attempting to use either of these on the K3/K144XV to send DTFM
tones on 2m to access my local internet linked repeater.

Although both of these mics have an RJ45 8-pin modular plug, I have
fitted an 8-pin plug to fit the K3 with the assistance of the
information on the G4WPW website. The microphone audio works OK and the
keypads illuminate with the +8V applied, but I cannot get the tones to
work.

Any help and experience of others would be most welcome.
