I used serial data with my K3S/P3/Steppir/HF Amp set up for a long time
by using Y cables to get data to all of them. So finally decided to
change over to USB 100% which I did but now using the CBLP3Y cable on
the K3S/P3 combo I am still going to need some kind of Y connection
again to tap off of RXD/TXD. I am looking at making a Y cable to
install between the P3 PC DE9P connector to pick up RXD or TXD from it
and let the amp monitor that. I know you can buy cables and even
circuit boxes to do this but I wanted to build this one myself as I
built the one Steppir used and it worked great. If you want to see
what Steppir does, S13 cable, see the link below.

If anyone has done this home brew I would like to know how you did it,
ie which connector on the P3 and which pins. I need more than just band
data provided by the ACC plug for the amp and Steppir. Too bad there is
not a RXD/TXD tap in the K3 ACC plug or a tap plug in the P3. I guess
one could be installed in the P3 blank slots and tap over to the RXD/TXD
connectors, 73 Mike K4PI
