Recording Radio Traffic/ Quantars

I am looking to install Digital recorder to record about 8 to 12 radio channels. I read various posts on this topics suggesting various sytems (nice, omnicron etc). The question I have is, the installation.

The site contains numerous M's CommandStar consoles sending receive audio back via Wireline. All consoles have various mix of receive channels. Does it make sense to locate this unit locally at the repeater site and then how to use the Wireline audio to feed the recorder. Any tips for the experienced folks will be very helpful.

Nice.com has a good solution for that sort of thing.
Easiel if you have a centracom but i assume none of your channels are trunked

Nope, they are not trunked. All are conventional.

Public Safety or commercial?

Ok that changes things as it could be evidence admissible in court.
Don't by a Dat tape machine
get a recordable DVD unit, they last longer and are less grief
Either Eventides or Nice.
Personly I prefer Nice becuase of their trunking interface , but both companies make good units

It is obviosly easier at the console site.
Are you using tone or DC
4 wire or 2 wire

unfortunately, a mix of all
Tone & DC
4W and 2W

Predominantly, Tone and 4W

What you need is some 4W to 2W converters with low pass filtering to take out the tones and the LLGT.
These are available and generally the recorder supplier will have these.
Withou them each channel will need two record channels which makes playback a nightmare.
The DC stations should also have a 4W to 2W with DC block.
Again pick the manufacturer and make sure they can do it,
Any of the big ones should have no problem

Thanks, looking at nice.com. They have some interesting stuff that even has ANI decoding.

Another vote for the NICE (Mirra) equipment. I love the thing.

This might be kinda off topic but is there a known setup or device that can record audio and log the actual units TX/RX activity?

I can see getting a recorder for the audio - sounds simple enough but recording and logging data from the tx/rx? I have considered getting a analog input card for a computer and logging when the TX/RX led's light up (soldering wires to led's on the circuit board).

I have also noticed in the (MTR2000) RSS that you can visually see when the radio is transmitting. Anyone know of a way to just log that activity?

Are the consoles CommandStar Lites? Why not just use the recorder connections from the Commandstar Lite punchblock(s)?
