It's been a long time since I last used WSPR. I find that my Icom and Elecraft radio's CAT control has somehow changed from lower COM Ports to higher (COM18 & COM22) ports.

When I use Windows 7 Device Manager to try to reset the COM Port to a lower number, the system shows all those COM Ports through COM23 as "in use".

I recall seeing a procedure one time to "clean up" those old COM Port assignments but can't find that article now.

Device Manager only shows 3 active COM Ports, but the system seems to think that COM1 through COM23 are in use or assigned to "something".

Any suggestions ?
