John,
I am sending you the schematic for SteppIR's Y cable. Pay attention as
pin 5 is not connected between the SteppIR and rig. The jumper on the
SteppIR end is between 7 and 9 (not 7 and 8).
You can not parallel pin 3 (Transmit Data) on two RS-232 devices.

John,
What needs to "make sense" is that you can only have one driver on an
RS-232 line. It is not a matter of "making sense", but is a technical
requirement. If you have two devices trying to send stuff at the same
time, the result at the receiving end is garbage. In "HamSpeak" we call
tha
Got it! It didn't make sense to me but once I inserted the "S13" cable from
the K2 to the Y cable, removed the TXD from the SteppIr DB9 and changed the
jumper from pin 8 to pin 9 per SteppIR and Don, it all worked. Whew! Ok,
only the S13 cable didn't make sense but it works so I guess it doesn't
y the SteppIR controller. That worked for me but I have not had the
problem repeat so it may have been just a temporary software issue.

John,
You said you were "building a Y cable". I do not know the configuration
of your cable, but it sounds like you may have the transmit data
connected from both the SteppIR Controller and from the computer - the
transmit data from the two sources will "fight" and communications will
cease.
I built my serial cable for the K2 to talk to my SteppIR controller from the
Elecraft manual. Works just fine. It also talks to my computer for HRD, N1MM
etc. So I decided to work on having the two interfaces work together like they
did with my IC 746 Pro. However, building a Y cable doesn't se

That's pretty cunning! clever stuff.
Incidentally, you mention "RF GAIN (normal, PREAMP, ATT, or both)" - is

Hi,
I finally got my serial interface to the K2 in a "finished" box.
Please take a look and let me know what you think.
