I have managed to get the PMR446 gateway back on air within the last 24 hours, using the 80GB WD hard disk, the original Maxtor hard disk has completely failed and has been removed from the machine awaiting tests to find out what happened to it and if it can be salvaged.
Reconnection of the autokey device to the computer was straight forward, it worked the first time, though there is an undesirable hum in the received audio it does not have a major effect and transmissions from the gateway are perfectly audible. I may look into fitting a ground-loop isolator onto the gateway to see if that cures it but it isn’t a major issue at this time.
The gateway is operating on it’s usual channel and CTCSS, so feel free to use it if you are in Richmond, you may not get a reply immediately but be patient.
