Replacement battery for YAESU FT-817

Product Information

Audio processing can actually end up making your speech less intelligible, because it produces in-band distortion products. Those packs are usually made for RC purposes and in the first moment I thought that they perfectly matches all of my needs.

This is done so that the circuit is inactive if one uses a holder for normal cells (the famous "green wire"). Tom Watson, then IBM chairman, who said in 1958: ‘I think there is a world market for about five computers.

If the battery pack was very discharged then it’s possible there might not be enough volts on the green wire to disable charging, this could cause problems with a flat Alkaline battery pack.Computer control is not something I personally have much of a use for with this radio, as for me the 817 is a portable radio not one to be used on a desk near the computer. These have a circuit in them that isolates them if you try to draw current when the cell is discharged to its minimum voltage. See the AT range of antennas in HF Mobile Antennas, these have been specially designed for single band use with the FT-817. They’re not as energy dense as lithium-ion, but they far exceed the energy density of lead acid batteries. Let's face it, out portable you are probably going to be using a pretty inefficient antenna, so being limited to 2.
