[amsat-bb] CAT cable to FT-847

[Floyd Rodgers]

FYI: the 847 has a standard serial port on back for CAT and programming. 
If you are using a special cable it must be because you no longer have 
computers with a serial port. I am lucky that almost all mine still have 
them (intentional). On the two laptops without serial ports, I use 
gearmo 4 port devices, the desktop uses a 8port PCI board from MOXA. No 
issues ever with either device.
