Relavant For Raspberry Pi , dont recall the issue on other hardware, but potentially is. The only choices are usbradio or simpleusb so far. I'm being pretty pretty picky, but I think its an important manner to discuss. With usbradio, the audio sputters and sometimes gets pretty bad. It never breaks up enough to loose what someone is saying, but definitely could use some improvement. It doesen't seem to be affected weather I use dsp or usb/usbinvert from the carrierfrom parameter. Wth simpleusb, the audio repeat delay is not consistent. Sometimes I will get a nice and good 0.25 second delay, but other times it will go all the way up to 1.5 seconds. This varies and I have not been able to control this, really annoying to hear not just the last syllable but my entire callsign when I unkey the repeater. Any solution to eliminate both problems?? And I know I am being really picky, but the more I hear it, the more noticeable it gets and starts to get a little annoying. Thanks, Skyler
