I am new to using a thumb dv with BlueDV software. I have the thumb dv connecting and working with DCS and XRF reflectors only. Have confirmed QSO's. I can only hear on REF reflectors. when I appear to be transmitting I am not. I have updated all of the host files. I am at a loss. I am using Windows 10 64 bit. Any thoughts on why I can not transmit to any of the REF reflectors?
