[Elecraft] OT Bluetooth Serial adapters

[Gwen Patton]

Dang, I misread your post, and didn't see the "serial" part.

I don't use BLUETOOTH serial with my KX3, because there's no way to get the
pairing code. I DO use a 2.4GHz dedicated RF dongle to a wireless keyboard,
that I plug into my PX3. Since it's dedicated, it doesn't need to "pair" to
the device, it's just always connected when active. I tried using wired
keyboards to use the CW/PSK/RTTY feature of the PX3, but I always got stray
RF in the cable, causing unpredictable results, including extra characters
in the keyboard buffer that kept the transmit going past when I'd stopped,
sometimes indefinitely, since the new output stuffed more garbage into the
keyboard buffer. The dedicated wireless doesn't suffer from this, so I can
use the keyboard without problems. (And YES, I did try toroids, chokes,
etc. No help.)
