Prm80

[Porcupine]

Hi, playing with some PRM80 series radio's at the moment, programming using v4.1, it comes up with unknown radio code and to contact philips, when trying to talk to some UHF radio's. Works fine on the VHF ones. Is their a later version i should be using?. I remember with the old FPP for FM92's their was a "switch" you typed when loading FPP to enable out of band programming, is their a similar thing for the PRM80's. I want to go down to 145Mhz for paket and APRS.
Cheers
