Jeff,
Years ago, I measured the output frmo my two FT-817NDs. One was purchased in 2004 when that model was released, and the other in 2008 when I started working SSB satellites. Both of these radios will transmit at 5W on high power, across 2m and 70cm, when I tried this into a dummy load.
These radios will default to the 2.5W power level when powered on internal battery packs that don't provide some level of voltage above 11V, but can transmit at 5W when you select that power level with the PWR button. This was the case with the Yaesu NiCad packs supplied with the radios, and with aftermarker 9.6V NiMH packs I had been using for many years. I now use the Windcamp LiPo packs that are nomially rated at 11.6V. With the Windcamp packs, my radios power up and start out at the high (5W) power level, instead of having to manually select that with the PWR button. I also like the separate charging port for these packs. Since installing the Windcamp packs a few weeks ago, I have been happy with how they perform. Charging is easier, and quicker, than using higher-capacity NiMH packs as I did in the past.
73!

Has anyone ever taken time to actually measure the tx power on vhf and uhf of the FT -817 ? After receiving a new one this week ,I took mine to the work where we have all the eqpt to spec it out and was disappointed with what I saw. Thanks to all who reply. Jeff WB8RJY
