[amsat-bb] Falconsat Success

Congrats, Tony!

The following relay has been working very well for me to handle PTT:

... I use 5 VDC from a USB cable for the coil voltage with the application
of that coil voltage being triggered by the serial RTS signal from
HS_Soundmodem.  The above relay is great for that since the coil circuit is
controlled by an opto-isolator that can be operated by a low level signal
like the serial RTS.

The following item sure made it easy to attach a pair of wires to serial
RTS & ground:
