[chirp_users] Chirp Data transfer

[Ken Simpson, W8EK]

The USB cable is a direct cable with a USB connection on one end, and 
the 3.5 mm 4 conductor plug that is normally speaker mic, but used to 
clone.  Nothing in between.  It was purchased specifically for the VX-3.

The "real serial cable" comes from the 9 pin D connector to a 3.5 mm 
regular stereo connector (3 conductors including ground), that then 
goes thru an adapter to the 3.5 mm 4 conductor plug used for cloning. 
  Years ago, this worked fine this way with a VX-5, so I doubt it has 
changed, unless the VX-3 and VX-5 have the TxD and RxD switched.

At this point, I am thinking that possibly the plastic around the jack 
on the VX-3s do not permit the cable to go all of the way in.  It 
looks like it goes in all of the way, but it is really up against the 
plastic case, so it is hard to tell for sure.  And no way to really 
test that.  Of course if it was not in all of the way, the TxD and RxD 
connections would not be the right place, and it would not work.

Of course one would hope that a cable bought specifically for the VX-3 
would fit the VX-3!

Any other ideas?

Thanks.
