This is a partial repost from the FB group, but last night I couldn't use VarAC on 14.105 due to digital QRM. The bursts were somewhat long, and on FB it was suggested that was HF packet. Moreover, the reply indicated a long standing HF packet net/group on 14.105 LSB: https://www.qsl.net/kb9pvh/105.html
My questions are 1) if the packet net is on frequency and LSB, will VarAC work on USB on the calling frequency (suspect yes)? 2) but a QSY to a lower frequency/channel will potentially collided with the packet net?
TIA! 73 de ke5c op john
There has been discussions here on the Forum on what slots could cause potential QRM to other users such as the 14.105 packet users. Here is one such example of a post here. https://www.varac-hamradio.com/forum/varac-hf-discussion-forum/slot-occupied-frequencies
