[Elecraft] WSPR (OT)

[Victor Rosenthal 4X6GP]

When you configure a WSPR transmitter, how do you decide what is the 
best frequency to use within the 200 Hz. WSPR range? I looked at the 
spot database and nothing jumped out at me.

Further details: I just assembled a QRP Labs U3S standalone WSPR 
transmitter, with a GPS receiver. I will probably start on 30m because 
that is the band that is available when all the relays in my antenna 
switching system are open, so it will be easy to let it run while the 
rest of my station is off.

Sorry for the OT post, but there are lots of smart guys out there! 
Answers can be off list.
