Reduced 10m power from 2W to 1W on WSPR

The Ultimate 3 WSPR beacon kit (on order) gives about 130mW out from a 5V PA supply on 10m. Using a 12V PA and more FETs in parallel should lift this to >1W out, so today I have been using 1W out to see what spots I get. Actually, so far, results are much the same as with 2W.

1W 10m  unique WSPR spots today

UPDATE 1244z:  10m band just opened to the USA. Absolutely no problems getting stateside spots at 1W rather than 2W.  Tomorrow I shall use 500mW. Stateside spots ended for me at 1716z.
