I have the G305 external with the Pro Demodulator and having APCO-25 will really add to the value of the recceiver.
I see it says it is out now in Monitoring Times Feb 2007 but the WINRADIO site indicates it is not - to add to the confusion, after "registering my interest" I got an email saying it is out and someone would contact me shortly. My experience so far is they are very quick to reply to email and eager to help.
So we'll see...
