10m with125mW (Ultimate 3 WSPR beacon)

As you may recall, I am building an Ultimate 3 WSPR beacon for 10m as soon as I feel up to the task. Currently I am too clumsy building because of my stroke. The reports yesterday and today with 500mW on 10m suggest the majority of spots would still be achieved with 6dB less power, QRM permitting.

Just maybe I'll try the beacon initially at its 125mW design level.  I was intending to run about 2W pep finally.

My last 500mW TX burst on 10m (at 1634z)  just now got no less than 11 different spots, with all but one (IT9) being received from the USA.  And conditions today are not as good as yesterday!

UPDATE 2300z: The last spot of my 500mW 10m WSPR signal was at 2136z tonight. My last spot (of others) was at 215oz (KE5XV). Best spot of my 500mW signal was from CX2ABP at 11127km
