[arm-allstar] Kenwood TH-D74 DTMF troubles

[Lloyd Duck]

Doug,

I've moved the RX levels all around to try and get it to decode. Best I get
is a decode of *, 4, 7 and 8 no other dtmf numbers or letters will decode
from the Kenwood TH-D74. 

I did check the level compared to the Icom ID51 and Yaesu FT2D and the
Kenwood is a little lower but not by much.

Fob's I'm using RB-USB RIM RIM-RC21-/RLC on the Arcom 210 controller on one
node and RIM-Maxtrac on a CDM-1250 for the other node I've tested.

I get the same results for the TH-D74 dtmf on both.

Mike,
I double checked the setting in the Kenwood and mine are matching yours. 

I'm just trying to send dtmf *82 to say the time.

LLoyd,

   did you check levels on the D74 vs. the other radios? It is possible the
DTMF levels are significantly different. The pre/deemphasis setting is based
on your node radio's requirements. What is your node radio? FOB?
