[Elecraft] OT Bluetooth Serial adapters

[Gwen Patton]

I have a small Bluetooth adapter that I sometimes use. It's about the size
of a silver dollar, with a short wire with a 3.5mm TRS plug on it. Since I
routinely wear a Bluetooth headset, I can plug the adapter into any 3.5mm
TRS output and pair to the transmitter with my headphones, and don't have
to deal with yet more wires just for my headphones. The only reason I don't
do it more often is that my headphones will only reliably pair with one
device at a time. There IS a way to pair it to two devices, but I've found
it unreliable and don't use it.

It's a help when I have want to connect to a bluetooth speaker, but don't
want to use the AUX cable. If I change devices, I can move the transmitter
to the new device. The only issue is that it's just as easy to use a jumper
cable to the AUX socket on the speaker, and the wire doesn't really cause
that much of a problem.. So it's almost more trouble than it's worth. But
it DOES work, and works just as well on my KX3 as on anything else.
