[600MRG] WSPR DX map...

[Dave Riley]

Am seeing much retraction of earned DX in the past 48 hours...
What do you folks use for WSPR 630m DX watch?? k index??

The two piece 630m antenna here went through a blizzard last night and 
has yet to detune or break after 8 years...

One capacitor and a few hundred feet of wire is the least common 
denominator for an antenna I can find...
Keep it simple...

As for miles per watt, what is a big number for 630m?? eirp times 
distance divided by eirp??
