[arm-allstar] DTMF

[David McGough]

Ken,

In 99% of the cases, RADIO_RELAX isn't the problem. The issue is typically
either received audio levels or an equalization (meaning de-emphasis).

I've -never- had a case where I needed to turn RADIO_RELAX on and don't
have it enabled on a single system---and, all decode every DTMF digit just
fine (including my Baofeng 888 portable systems).

Anyhow, yes, there is a setting in V1.02 forward, where RADIO_RELAX can be
dynamically turned on/off at runtime (to enable, set: dtmf_relax=1 in
simpleusb.conf device stanza), no recompiling needed....However, this
"solution" is probably just masking the real issue and ideally should be 
considered a temporary work-around while identifying the audio issue.
