If you want to solve your CHIRP to repeater memory setting Yaesu upload bug, then see the fix that I posted today at CHIRP Bug #1433: "MAC OSX 10.9.1 Yaesu VX-7R Upload Fails". The solution is to remove your FTDI VCB driver and instead use the Mac OS X 10.9 Mavericks provided built in Apple VCB driver. Pete Mackie KG7IXU
