Remember the old 14105Net was hf Packet on 14-103.5 LSB so there will be some interaction .There are still HF packet stations out there as well as many other modes using this portion of the frequency( straight off the bat I can think of at least 6 other modes been using this portion for a long time ) , before VaraC came along . It happened to most of the modes in the past 10 years where a mode selects frequencies deemed as fixed but this is not possible due to so many modes and common aspects to using that particular frequency . If you want to listen to packet ( those long bursts ) one can try soundmodem114 and Easyterm49 on windows - works great and easy to install . 73 de Bradley M0JXR
