[App_rpt-users] Anyone using MDC1200 for control?

Tue Mar 23 19:13:51 UTC 2010

Yes, it makes some output when it happily decodes a unit id

For those wanting extra functionality for "buttons" or whatever
it is your radios are equipped with. If someone could give me
a recording (of the receive input of a receiver listening
to your transmiter) of the output your transmitter as you
press the buttons you are interested in, and then tell me what
you pressed in what order, I could use that recording to do
what I need to do. Probably the best way to accomplish the recording
is to use the URI as a regular sound device (like on a windows machine
or Linux) and use a standard sound recorder program or editor
(like audacity) to make the recording.

Thanks!!
