I was having trouble hearing audio on Wyolink by using Arc 96. I could get everything but no audio,Itried about everything to no avail. I decided to try Win 96,Behold a miracle everything including audio. Also Arc 96 would not let me input some of the longer frequencies. A friend and I now have 2 Wyolink friendly Pro 96 and it also worked in my 2096 whitch I could program with Arc 96. I am just curious does anybody have any answers WHY?
