Hello everybody,
can anybody tell me, if it is possible to realize / install a separate cat jack without using the present USB port,
by going straight to Pin 1, Pin 2 and Ground on the Arduino Nano?
If I have understood correctly the built in cat interface? in KD8CECs firmware uses the USB connector
just as an RS232/TTL converter
Am i right, if I assume, that it should be possible to solder some wires to D0 and D1 (RX + TX) and ground and then install
a MINI-DIN 8 socket to the uBITX like in an FT817?
I am asking because I am building TF3LJs Magnetic Loop Controller? at
the moment, which communicates with the tranceiver via cat for tuning the antenna. This interface uses just these three lines. So I need to make them talk :-)
I would just try it, but am a little bit unsure if i might damage something, if I am wrong. I am not really fond of grilling the Raduino.

Sascha,
? THANK YOU for linking to this project - I've been trying to figure out how to put a loop in my attic for close to three years - this is PERFECT!??
? ?I noticed that Loftur has a 'pass-through' mode.? I wonder if that will do the job??
The USB port can also be configured for Serial port <==>USB port passthrough mode, enabling computer control of the transceiver.
? ?I'm interested in exploring this as well, as I'm hoping to use cat to let my ?BITX talk to this box an an off-board PA.
