Replacement battery for YAESU FT-817

Product Information

As this is in a range about 10% or so this does not matter compared to the weight of my old SLAB batteries. This makes it an ideal "do-anything" radio, suitable for whatever kind of operation you feel like doing. Close to the plug, as many turns as possible of the thin twin-flex adapter lead were tightly wound onto a ferrite core as used for curing breakthrough problems.

The two most popular no spot welding no soldering methods are the Vruzend 18650 end cap builds, and the sourcing map battery tray method. My FT-817 sits quite happily on top of my Maplin 3A power supply and looks as if it was made for it. It also has an LED flashlight and a built-in charger that accepts 5v DC via mini USB, or 13v DC via a very small barrel connector for use with the supplied auto accessory plug charging cable. That's partly because the AGC in the receiver used to make the recording has brought the signals up to a similar level. Now if you’d like to avoid all of the trouble of going to the airport with an external battery pack, there is one internal battery pack which functions really well.Operating the amateur bands from a quiet spot is a treat but don't overlook the rest of the spectrum either.

To build the largest and most complete Amateur Radio community site on the Internet - a "portal" that hams think of as the first place to go for information, to exchange ideas, and be part of what’s happening with ham radio on the Internet.It will also draw the least attention from the Goon squads trying to find reasons for you not to get on an airplane. Stations between about 600 and 2000km can become stronger than those 50km away when the propagation is in. As a Lithium-Ion pack they have more usable capacity than the same physical size of double AA batteries mounted internally. Installation involves opening the FT-817 and substituting the new TCXO for the old crystal oscillator. But in my experience people who are not CW fans don't like the mode because they find it too difficult to use - because they didn't learn it properly.

Grounding the radio to a suitable earth such as a radiator made a big improvement, but the hash was still intolerable. A contest-grade receiver isn't expected nor required in a radio of this type, but the FT-817's receiver seems poorer than it need be. Some hash is still noticeable, but it is not strong enough to drown out any station who is strong enough to indicate he has a chance of hearing my 5W signals.

It’s sold for jump starting cars, which really works – I had to use it to start my lawn tractor once.

If you know what you’re doing, if you’re not afraid of blowing yourself up or burning your house down, here’s the first and only lithium-ion pack build we did on the channel. Used the charger twice with no problems, and then on the third charge, after about 3 minutes the charger sparked and tripped the MCB in the consumer unit. AM is already a compromise compared to SSB but stations worked reported weaker than expected modulation. In the long-term they’re terribly expensive because you will have purchased and thrown away 4-8x of these batteries, before you even reach the beginning of diminished capacity, for a single lithium iron phosphate battery of similar capacity.It is not safe to run an FT817 on external power with LiPo cells fitted even if the green wire is disconnected. See the AT range of antennas in HF Mobile Antennas, these have been specially designed for single band use with the FT-817.
