Two months ago I tried IAX_rpt with my asterisk setup and found that the on-the-air transmit level was way too low, no matter what I did at the GUI client end (Windows XP). A friend of mine tried it on his computer and got the same result. (The current version 1.1.27). The bar graph for the microphone level seems way too high for the audio input, compared with other programs. The output bar graph seems to track the repeater's audio, but the sound level being produced is low (again, compared with other programs). It's as if there is some fundamental scaling error in the audio processing in IAX_rtp. I am wondering if other people are seeing this. Or saw it and fixed it. Posting something here resulted in a suggestion to post my observation at the Xeletec web site - which I did - but after 8 weeks - no answer from anyone over there. In fact, no one is posting anything new over there at all. It's a nice tool but, in my experience, it's unusable due to bad audio levels. Ken KE2N Allstar 27021/27061
