Can't beat the price either....

Subject: Re: [Elecraft] FSK-D wiring
This is the approach I have used since K3 Field Test. I just keep adding
Y-adapters as needed. Another variation I've used is to build specific
Y-cables. For example, I have some homebrew cables that have two cables coming
out of the DB15 plugged into the K3 ACC jack. One goes to a DB9 for a KRC2 and
the other goes to a DB9 for a PC Com port for FSK/PTT.
Another approach some people like is to make a break-out box with RCA Phono
jacks for each of the signals on the K3 ACC jack. The box is connected via a
single DB15 cable.
I prefer the multiple Y-adapter scheme because it is modular and individual functional
cables can be swapped in and out both for easy configuration of any system as well as
easy troubleshooting. It is about as neat a "cable mess" as can be had without
making a specific special cable for just one configuration.

The recent FSK-D firmware update has me considering wiring up for that
approach vs my current AFSK approach. Since I don't do RTTY that often
I'm looking at FSK-D as a potential screw-up preventer.
Since I already have a Y-cable to send band info to my RCS-12 and the
rest of the K-line on the other half of the Y, I'm considering just
getting a second Y cable and dedicate it to the FSK/PTT signals coming
from a dedicated USB serial cable.
This is turning into a real jumble of cables but I don't see any
cleaner way of dealing with it. I'm planning to put the
transistor/level shifters in a gender changer shell in between the USB
RS232 connector and the Y cable.
Anyone have anything cleaner? The electrical part is easy for me. I'm
trying to minimize mess/clutter.
