The FT-817 is advertised as a 5W radio. But on battery power the maximum output power is normally 2.5W. This can be overridden, but bearing in mind the limited battery capacity this may not be a good idea. But it's disappointing. Let's face it, out portable you are probably going to be using a pretty inefficient antenna, so being limited to 2.5W as well isn't going to help.

This will charge the above batteries (and other Lithium cells and NiMH and NiCd etc.) Hobbyking Radio Control Planes, Drones, Cars, FPV, Quadcopters and more - Hobbyking TX Frequency Coverage: 160 - 10 Meters, 50 MHz, 144 MHz, 430-450 MHz, plus Alaska Emergency Channel (5167.5 kHz). But there are limitations. The built-in batteries will not last thirty minutes when transmitting, that's not really practical. Also, the internal battery supply will limit you to 2.5No ATU. The FT-817 has no internal ATU. Originally I thought that this was a reasonable design compromise. However, having experienced how hard it is to get small portable antennas to match in the varying environments in which they may be used, I began to realize that an ATU would be very desirable. Most ATUs are the size of the FT-817 or larger, which negates a lot of the benefits of the radio's small size. However, Elecraft has recently introduced a tiny portable QRP auto-ATU, the T1.

I was particularly interested if anyone was using a 3 cell LiFePo4 battery, giving 9.9v? Does this set up work reliably with an FT817? It seems that LiFePo4 are the better solution nowadays (more charging cycles and more stable) but I own a cheaper LiPo 3 cell 11,1 Volt 2,2Ah and it keeps running all right with me since 3 years now. I can run my 817 during 2 hours full activation without an issue.

This FT-817ND is boxed and in great condition as it has been well looked after. The radio is unmodified and gives 4w on all transmittable bands (40m is only 7 - 7.1Mhz although RX is up to 7.2Mhz). The FT-817/FT-818 has a wide voltage range but you want to avoid a battery that gives around the extremes of this. Too low a voltage (eg 8 - 9 volts) will mean the FT-817/FT-818 won't be able to put out its full 5 watts thing you'll need is a horizontally polarised antenna, preferably a small beam. Height helps but is not imperative; Summer can turn often dead bands into active segments with massive signals. The cause is sporadic-E propagation, a phenomenon most noted in mid summer, and, to a lesser extent, mid-winter.
