Title: Yaesu FT 857D DTMF microphone problem
Post by: KG4RSH on March 20, 2005, 05:24:02 PM
Can someone assist by telling me how to fix this problem. I was using the DTMF microphone on the rig, (Yaesu ft857D) and then switched to a regular microphone. The radio being menu driven, I changed the related menu from RMT to NOR as outlined in the operating manual, but when I was ready to use the DTMF microphone again and after switching back to RMT in the menu, I could not get the microphone to work properly. The only functional button is the power button. I did a micro processor reset but that never changed anything as it relates to the microphone. What could be the problem and how can I get it solved. I anticipate a response.

  You have to switch to remote mic in the menu prior to putting the mic on the radio.. Try that and then email me back.. I am pretty sure thats your problem.. Richy N2ZD

Could you tell me.....are you using the dtmf mic that they sell for the ft857 or are you using one from another radio? I have a dtmf mic from a ft2500 but don't want to try it until someone tells me they have had luck with it. I hear that the control heads are real sensitive to getting blown with erroneous connections.
Thanks & 73,

FYI......I took the plunge. I tried my FT2500 mic and it works fine. Better than having to buy another mic.
