Yes, if you plan to isolate the HR50 USB port, it's VERY important that the USB connector not make contact with the case. You might be able to put insulating tape around the bode of the connector. Even if you do there is a chance that you'll need to file the opening a bit larger.

The new rear panel boards are in production and should be ready in a week or so. They use an FTDI chip instead of the MCP2200 which should help with driver issues. The USB is full isolated from the HR50 which will eliminate ground loops and the USB chip is powered by the USB port so it won't appear and disappear then the HR50 is on/off.

We'll make the rear panel board available for stand-alone purchase so anyone who wants/needs an isolated USB port can equip their HR50 with one. You'll still need to file the panel.

Thanks Jim,

One additional question. Does changing the USB driver change how the com port is assigned? The reason I'm asking is that the need to use the DDutil software is necessary (I am referencing Mick's method described above) as currently the HR-50 is assigned a com port automatically. If it could be assigned via setup, than it could share the CAT information in the same fashion that my logging software, contest software, keyer ect does. That would eliminate a software layer as then the HR-50 would play nice with the VSPE software.

Thanks.

MJ

Hi MJ,

Poke around the driver settings in device manager maybe it has a setting for com port. As far as I know, the port assignment is performed by the OS and every unique HR50 gets a new port. I have a procedure for removing unused ones which I have to do occasionally.

You might also ask the question on a Microchip forum maybe someone there knows.
