[SMCARA] WSPR...Worth a look

Hi All,
Well Fletcher had led me astray, one more time.
On his recommendation, I tried WSPR (a subset of WSJT).
I set up this morning at 0530 to beacon with 1 watt (+30dbm) on 40 meters
(7.038600 MHz). Before 1010Z, I was using my 3.5 MHz Dipole fed with 450 Ohm
resonant feeders (tuned for 1:1 SWR at the operating frequency). That
antenna is up just 40 feet and is broadside east and west. After 1010Z I
was using a 40 meter half wave dipole at 60 feet and broadside NE / SW. The
latter antenna did better with the VKs.
Here is a list of the furthest stations to have decoded my beacon (sorted by
kilometers per watt):

Here are some beacons that I decoded; sorted the same way (kilometer per
watt). The W2 is on top because he is running just 10 milliwatts. My KH7
(Hawaii) doesn't even show because he was running high power (10 watts).

Here are the best distances for W2GNN sorted in km/w (the list includes
spots made over the past 30 days). This proves that with almost no power
and persistence (and WSJT) one can do some pretty neat things.

It looks like W2GNN occasionally has a pipeline into HB9 with his 10 MW
beacon.
Now, if we can get JT65-HF out from under all the locals with huge signals,
we should be able to do two way contacts over distances like this with just
1 watt or so.and they count for WAS / DXCC, etc.
