[chirp_devel] VX2r update (nothing to report)

Hi all,

I moved apartments and have been setting up my workspace again.  Unfortunately 
I have nothing further to report.  I have tried my 3V3 and 5V FTDI chip 
interfaces and neither work.  I can receive data, but I cannot transmit, so 
the radio halts at the first block.

It worked once, but I haven't been able to reproduce that.

I will now try to add a transistor buffer on the transmit line (from the FTDI 
chip).  Maybe it can't pull down hard enough.  I did run the FTDI chip 
utility to turn on the high-current output drive, but no effect.

Yes, I could buy an interface, but that will teach me nothing.

73,
