[Icom] programming UHF radio help

[Gary Fiber]

Bill,

The OPC-478 programming cable uses the Ring and Sleeve for programming not 
the Tip and Sleeve 2 conductor connector that works with your 756ProII.
You could build a small convertor the chance that or add another cable to 
you 756ProII cable. I have an OPC-478 that has 3 connections on it, 3 
conductor phone plug, RJ-45 and the old F30 series connector.
Also as Fern mentioned sometimes the computer is to fast for the dos based 
programming software. But more likely Windows XP does not like to 
relinquish port control to any
software. I have read and experienced that with a small home controller 
software package. If you don't have one, download a Win 98 boot disk and 
try that.

Also before you do anything to the F420  READ !!!! the transceiver. There 
is hidden data within the transceiver that if you have not downloaded it 
you will never get the F420 programmed.
This hidden data is not in the software as it boots up. I do not remember 
any buttons to place thew F420 into cloning mode. Looking at the software 
help system might tell you that. Seems to me the F420 sees the computer one 
it is connected and the software tries to read the radio.
