[Elecraft] FSK problem with my K3

[stewart at gm4aff.net]

I have been trying to make FSK work with my K3 since last September on
and off (excuse the pun). I have tried 4 different interfaces, I have
traced through all the cables many times, tried different software,
tried different COM ports, I have torn my hair out, etc.

I have a splitter on the output from the K3's ACC socket to an Export
1.3k, a band decoder and an XV144 transverter, as well as the FSK keying
lead. As a last resort I tried unplugging the various peripherals one by
one from the splitter box. And hey presto, when I unplugged the
transverter the problem is finally resolved and I can hear diddles
emitting from the radio! The transverter pulls pin 1 down to earth! This
is a serious issue! I haven't gone any further yet, to investigate why
pin 1 is even connected to the transverter.

Now what if I wanted to operate RTTY on 2m??!

I hope this helps anyone else who has this issue.
