Apart from the serial-usb converter we have found the PIIex to work well so far. Someone did mention increased RF noise using the USB modem, but that was just a second hand comment I heard so cannot rationalise this.

We have Meteoscan Pro which receives fax, RTTY and Navtex - as you say that likes to control the radio itself directly. Still need to fettle with the setting on this to get the picture perfect though (but the Airmail fax seems to be fine so must be the Meteoscan settings).

I haven't used JVCcom - whats it like compared to Meteoscan?
