My interest is digital radio, costly proprietary formats are a secondary
discussion and an impediment to implementation in my view.  If LinRad
leads to a free protocol for digital communications and does so with
equal effectiveness to one that requires a $549. proprietary interface
one need not wonder for long which will flourish in Ham circles.

Neither system has, nor pretends to have the RF hardware.  The AOR
device attaches to the microphone input of an existing transceiver, so
this is a non-issue in the comparison.

The exciting thing about LinRad is that it has made amazing progress
toward a usable interface for multiple apps, is free, and is user
customizable.

I am already locked-out of Pactor III by the exorbitant price for their
proprietary interface and will have to wait for a Linux-based
software-sound card option.  I am hoping that LinRad provides the same
access for we less-well-heeled folks in the digitized-voice realm of Ham
Radio.
