Re: OPC-478 cable for Yaesu VR120?

Hi Tom,

Maybe a stupid question, but I reckon that both uploading and downloading
to/from the VR120 will work?

I ask since I read  that the OPC-478 may work on the VR120, but only for
downloading *to* the PC. Uploading *from* the PC doesn't seem to work with
that cable?!

The schematic indeed seems very easy to build, so if it works I don't
see the
need to use a MAX232.

Cheers,
/Marc
