You will need a constant level audio out, squelch-muted from the receiver.
Mix that with mic audio, muted with the PTT lead. The mixer levels can be
diddled to make the outbound audio match the inbound audio.
The mixer output is your audio source to the recorder.
Or just get yourself a scanner with a tape out jack, park it on your radio
channel, and pipe it into a box running a copy of Scanner Recorder.
The fact that you are running LMR trunking is not relevant as long as your
scanner understands LMR.

Thanks Bill,
My concern though is interfacing with ICOM F-521 DB9 rear connector
and transparently being able to record both TX & RX (network) audio
without disrupting/affecting the front Mic or Speaker that operator
uses consistently. I suspect some type of VOX circuit is required.
Your thoughts?
Rgds,
John

John ~
Several of us on here are Broadcast Engineers. I do this every day, (right
now 9 baseball games over 11 days) recording from my audio mixer board to my
laptop, and editing highlights (home runs and runs scored sound bites) using
an audio editor. We also mix the audio and affects, and send it back to the
home station (i.e. Tigers, Marlins, or Phillies for these 9 games) for the
live (about 3 hour) broadcast of the games. Most of us use Cool Edit, which
is now Adobe Audition.
HOWEVER ~ FREE IS BETTER.
There is a really great program that is FREE - called Audacity. I would not
hesitate to use it in the broadcast world. It does everything I would need
to do a broadcast. Go check it out at
<http://audacity.sourceforge.net/>http://audacity.sourceforge.net/
The audio quality is equal or better than our 20 Hz. to 7.5 KHz audio
broadcasts via ISDN from the ballpark back to the station. You can cut,
paste, change levels, and edit around anything you want, including smooth
out audio levels, very gracefully.

Subject: [Repeater-Builder] High Quality Recording Device
All,
I'm looking for a high quality recording device to record communication
(wave files) from a private broadcast LMR network . Recorder will need
to interface with ICOM F-521 base station possible via a repeater
controller of some sort. Recorder must be PC base for network archiving
purposes.
Any suggestions on controller or recording device?
Rgds,
John
