Well, I'm back after 3 days at the Orlando Hamfest. I had a great time meeting with quite a few ASL users that found me out in the flea market. ( have no idea how) I also had a chance to meet with a couple of hardware vendors about going forward with ASL. More on this later. Thanks to all. We have found the bug in uridiag that fails a known good URI with the loopback connector. In short, uridiag was not properly setting the audio output level. This does not in anyway affect the operation of either USB channel driver during normal asterisk operation. As with all ASL software, the source is published on GitHub at <https://github.com/AllStarLink> in the uridiag repository. For those that want to fix uridiag on their existing installations: login as root cd /usr/src/astsrc-1.4.23-pre/ rm -rf uridiag git clone https://github.com/AllStarLink/uridiag.git cd uridiag make cp uridiag /usr/local/bin You can now run the new uridiag. Make sure asterisk is NOT running. connect the loopback connector run uridiag 73, Steve N4IRS -- --- "Real programmers use vi, that's why I use nano."
