Well , with the current equipment available i decided the SBS had go back to the reserves bench.
I am now sticking with the ssstv and digital cams, with the main computer being used for general shortwave listening with the PCR-1000+8 metre pro Whip driven by Ham Radio Deluxe.
I've just had another go at installing RadioCom 5.2 and this time it worked. Think maybe i had some file missing since the last full windows re-intall, which has been rectified by automatic updates since. Anyway we're back in business and recieving Northwood fax again. For some unknown reason, the picture quality is better on this version than the later Version 6, which i also have. I'll include a screen shot in a minute. Deep qsb about at the moment, but picture quality is still pretty good concidering.
