I made the Yeasu FT 817ND work at 5 watts

Error in the Yeasu manual

After my previous outing with the 817, I decided to try to find out why I was only operating at 2 watts.  To my suprise, or not it turns out if you are running on an external power supply or car battery then the power indicator goes out to indicate its on 5 watts, when on internal power it flashes.  Problem solved.

So today I had a play and managed to talk to;

M6WYD John 7.129mhz station in West Yorkshire at 5 watts QRP distance 200 miles

G4BIZ 7.136mhz station in the New Forrest at 2 watts QRP, the QRM was terrible and we had to cut the chat short distance 60 miles
