I have a bunch of CM108 109 and 119 sound fobs from bulk purchases a couple
years ago when they were real easy to get. I could help you out if you want
on them, Shipping is usually more than the fob J

Contact me off list if you are so inclined. These are the real deal. 

I can do paypal and usps flat rate box's. if that helps..

Hi everyone,


After getting the repeater working in op25/asterisk i'm still stuck with the
problem of PTT control. I see on the app_rpt page there are instructions for
modifying a CM108 usb sound card (which i attempted to order, but the order
got cancelled because they are on backorder...). I was reading this page
http://yo3iiu.ro/blog/?p=324 and was wondering if something similar could be
done with the chan_usrp in asterisk (or soundcard_tx.py in op25). The part
that interested me was using a serial connection to do the signaling for



Just a thought,
