Hi

It is getting harder and harder to find utility traffic in five level 
code on HF. From what I have seen the whole HF scene regardless of mode 
has been going though a lot of "slimming down" for the last two 
decades.

Most of the news broadcast stuff went to one form or another of 
encryption back around 1990. There are still a few hold outs, mostly 
exciting stuff like North Korea. If there's any interesting news stuff 
out there these days on HF it's pretty hard to find. I would be 
interested in anything anybody else has come across.

The weather stuff has gone to sat links except for areas like mainland 
China. They apparently have a significant inventory of working TTY gear 
in airports over there.

Occasionally you will find a military circuit running in the clear. The 
  only ones I have found in the last few years were running quick brown 
fox tapes. The exception has been the RTTY weather stuff they 
occasionally send in between weather FAX transmissions out of Canada.

The high seas traffic went to ARQ or other error correction setups back 
in the 1980's. I have never figured out a good way to do casual copy on 
those circuits. Most of the decoders for that stuff want to talk to a 
computer anyway.

I suspect that you could reasonably keep one or two model 28's in 
service copying odd bits of this and that. Once you have enough parts 
to keep a pair of them running I'd say you are set up for a good long 
time.

Of course you should never discount the fact that I'm about a two hour 
drive from your stash of parts :)

	Take Care!
