[chirp_users] Programming Yaesu FT7900

[Dave Cavanaugh]

I am having trouble programming my radio via the programming cable.

I can get the radio into Clone mode by pressing the MHz PRI button on 
startup.  However, it won't go into TX or RX by pushing the LOW/ACC or 
V/M MW button as described in the "cloning" section of the manual.

When I start Chirp and go to "download from radio" it gives me the box 
with Port com 3, radio Yaesu and Model FT-7800.  When I try to download 
the profile from the radio I get the error message
"failed to communicate with the radio:  Failed to read header (0).

Now what?

Thanks
