[arm-allstar] DMK uri connections to Icom PCR-1000

[Doug Crompton]

Jeff,

As you know this is just a receiver so the audio out would go to the RX
audio on the DMK. Allstar needs a COS signal to transmit the audio. This
could be fixed - always on when connected or you could pick off a point in
this unit to drive COS. Here is the service manual with schematics... COS
can be fixed asserted several ways. The K command in simpleusb-tune-menu id
onr way. You could also set it to USB and it would stay keyed if not
connected to anything or USBINVERT and tie the lie low. Pin 8 is COS on the
DMK. When you do this and connect somewhere that node is always keyed and
sending audio from the receiver to the remote location.
