They do ask for assistance from their members, Mike.

They have a nightmare setup, trying to distribute audio over multiple
transceivers. Look behind the flashy vernier of their audio control panel that
they show the tourists and you find all sorts of ground noise potential. Why
in this day and age they don't use fiber optics like TOSlink to distribute
their audio is beyond me. A handful of chips and a soldering iron, and lots of
their problems go away, even when you take into account that they are using
AFSK (most of us know how to put out a clean AFSK signal).
On any given day, you will find some dirty W1AW signals on one band or the
other.
If they convert to using simple inexpensive SDR as exciters instead of those
Icom boatanchors, they can also distribute clean IQ data using Ethernet.
When asked, I usually try to help, but I do not go watch their daily
transmissions otherwise (certainly not after they dropped SITOR/Amtor FEC --
W1AW used to be good for testing demodulators and decoders for that mode; it
was also the most reliable transmission from W1AW).
