Ken,
Although *supposedly* the inductor should be able to supply the needed
current, I recommend replacing it with a toroid.
Especially if the inductor is of the older miniature type.
12 turns on a FT25-43 or FT37-43 core will work nicely.

I have been informed by those who really know that my statement is
incorrect.
If the K3 is set to AUTOINFO=1, the SteppIR should receive the K3 band
and frequency information without a logger being active.

I am interested in this as well. My KAT100 is complete in the EC-2 and I just

You know this but...
By hardware reboot, he means complete shutdown to power off; unplug power
source; count to a hundred by Pi; then bringing it all back up.
Sometimes 'off' isn't OFF and a soft reboot doesn't clear buffers (requires
power gone).

Rick, obviously if it worked before, and it's working now, your hookup can

One possible cause: The communication chips that send and receive this sort

Will connecting a K2's serial TxD/RxD lines to the KXPA100 (over the

I presume I would need to set the BPS to 4800 and either poll the K2 or
turn AutoInfo on for this to work. The assumption here is that the RJ45
