[arm-allstar] Did you know? Using a headset/mic directly with a FOB

[Doug Crompton]

>From time to time I will point out some features of the V1.5 hamlib code
that you may not be aware of. Today it is using a sound FOB with a
headset/mic.

The simpleusb-tune-menu code in V1.5 (Item 12 on the ADMIN menu) has a new
manual key option. The is the (K) for key in the menu. This manually keys
the COS line just like an incoming RX signal would from your node radio.
All you have to do is connect a headset and microphone to your USB FOB,
open the simple-usb-tune-menu application and use the (K) option as PTT.
This toggles back and forth by typing (K) followed by a (CR) carriage
return. You also must setup the RX and TX levels (menu item 2 and 3) for
the headphone/mic.

This is a real easy way to test your system and the most simple "radioless"
node you can build. You obviously would not want to operate this way for an
extended period but until you get a radio and get it interfaced this is a
great way to get on the air and check things. You would have no DTMF but
you could open another ssh window and use the Asterisk client to make
connections and send other commands manually. Make sure you don't leave
the(K) option keyed by accident. It will however clear (unkey) when you
leave the simpleusb-tune-menu application.
