I worked CU8AO/m in the Azores in 2002 along with a number
of European countries all with 100w and loop in the back
yard.  SP8UFT in Poland was quite a surprise.  
However, I haven't witnessed those kind of 6m condx
since that time.  Very disappointing.  I guess 2002 was
just an exceptional year for VHF and working across the
pond.

Hi Les,
I'll try to find some time to make a contact, since 6m has certainly been
uiet lately.  I've dropped into pingjockey in the past but haven't really
tuck around long enough to see things happening. I'm definltely a little
istol station, 100w into a loop, but from what you and others have said it
eems like that should be sufficient.

 Now that youve experienced decoding these signals, I hope youll consider
 making a few contacts too. Its easy to get started, and as youve seen
 random contacts happen every day on the calling frequency of 50.260. Or you
 can coordinate an attempt with a friendly station on www.pingjockey.net

 I recommend reading the mail on Ping Jockey for a day or two, and learning
 the lingo. Then reach out to a station about 600-800 miles away, which is
 optimum for Meteor Scatter and ask them to try a contact. Most experienced
 MS guys will be happy to walk you through the first contact. To be a valid
 contact, you cant exchange any information online during the contact, but
 for the first attempt dont worry about getting one in the logbook, just
 learning the process. Its easy and fun.

 Not only does it give you something fun to do during the long winter dry
 spell, but it offers smaller stations (like mine) a chance to work stations
 that might otherwise be impossible. 2 Meters is more of a challenge, but
 WSJT can still make contacts possible year-round.

 Again, thanks to all for helping, and as I noted (some may have missed the
 message), it was indeed ISCAT. If you've never listened, it does sound very
 different from FSK441 which is actually what I was expecting to hear there.
 In fact, after the signal went away, I did hear some FSK441 (also from a
 relatively local ham, it was MS) and was able to decode that as well.

 Thanks for the interesting diversion into the world of weak-signal digital
 modes.
