Folks, I recently began exploring the melding of two hobbies (Asterisk and amateur radio), and have made some encouraging progress. I have hit a bit of a roadblock, however, and am soliciting help from the experienced hands to identify what I'm doing wrong. We have an Asterisk host which is the core of the house phone system. It's been in production since September, 2003, and has seen several Asterisk upgrades and hardware enhancements over the years. The most recent upgrade was about a month ago, which brought in a new box running CentOS 5.5 and Asterisk 1.4.36. The box is populated with two Digium cards (T1 and quad-FXS) and is connected to an Adtran TA750 channel bank; we're using 18 FXS and two FXO channels. A few weeks ago, I spent some quality time on the phone with David Kramer of DMK and discussed his hardware, software, and implementation recommendations. We ended up purchasing a URI from him, and an interface cable for our Yaesu FT-847 from Marshall Oldham (KE6PCV). Using the ACID distro, I brought the original Asterisk box back to life as the wireless Asterisk host. The plan is to run a proof-of-concept project to determine if all of this is useful. If the answer is "yes", then we'll buy a dedicated radio for Asterisk integration and join Allstar. So, on to the present situation. On the house phone system, I have an extension which places an IAX call to the wireless system and connects to the Yaesu via Rpt(). When I call the extension, what I say on the phone is transmitted by the Yaesu and received by a monitoring HT. Big win! After that success, I attempted to set the squelch and voice levels with radio-tune-menu. I'm able to perform Step 1 (auto-detect the received noise level without carrier) and update the configuration file, but can do nothing else. I suspect that (at least) there are some wonky values in usbradio.conf; would you mind taking a look? I appreciate any help you can provide.
