Replacement battery for YAESU FT-817

Product Information

I use 18650 holders to charge and to test the capacity of my cells. You need to solder the holder that it matches your needs. I use 4 cell holder (charging, 3 in parallel) and also 3 cell holder (11.1V nominal in series for my FT-817). 18650 voltage 3S and 4S config I have not yet tried it, but 3400 mAh with the ability to charge it in 1 - 2 hours sounds like something. Look up islands near you and available ferry services. Aim to be self-sufficient, with an FT-817/FT-818, antenna mast, wire, antenna coupler and battery. Something around 8000 mA/H should keep A surprising number of FT-817/FT-818 owners use their rig on HF, and maybe VHF/UHF FM repeaters, but not on VHF/UHF SSB.

I hear stories about the volatile nature of 18650s so I am leery about making this without talking to someone who has already successfully built and used one. I believe this should be a pinned post for the rest of the year. I don’t see any change at least for the next 6 months in batteries. The bad points outnumber the good points. Whilst some allowance must be made for the FT-817's small size and portability, especially with regard to ergonomics, several of these criticisms could have been averted using existing technology.

default setting (at least on my rig) was not ideal. Not that most users would notice since few would use it on AM mode, but you might as well have it right, especially since the settings can be done from the My FT-817 performed well enough on SSB and CW but reports on AM were mixed. AM is already a compromise compared to SSB but stations worked reported weaker than expected modulation.

These have a circuit in them that isolates them if you try to draw current when the cell is discharged to its minimum voltage. i.e. you can’t over discharge them. It also disconnects them if the voltage applied to the cell exceeds 4.2V. With that type of 18650 and the green wire in place, the whole system looks to be fine and dandy. can decode (and who decodes you).

enjoy the novelty of working a pedestrian mobile station >1000km away as much as you did working them. you are right - I had blindly assumed that a modern LiPo can be charged at 0.5 - 1 C, but Panasonic seems to play safe and restrict the charge current to 0.9 A according to the datasheet. But still a nice solution, and since it’s based on cells with internal protection, it also looks like a much safer approach than the many RC model LiPo approaches used in the community - the RC batteries typically have no discharge protection and can thus catch fire or explode more easily. three (rather than two) screen lighting colours. The difference between the FT-817ND and FT-818 is negligible; if you already own an '817 you wouldn't buy an '818. It’s basically a nicely designed 3D-printable part for 3 x 18650 Li-Ion cells, load balancer, fuse, etc. Thanks to a new cover, the cell can be charged while inserted in the rig. I've been toying with the idea of getting a supped up FT-817nd. I know there a few options for a higher capacity battery and modded door that can be charged without having to remove. Windcamp and W4RT come to mind. What is the best option out there currently?When the power goes off don't just sit around at home waiting for it to return. Instead find a battery, fire up the FT-817/FT-818 and savour the temporary pleasure of exploring the unusually quiet bands. day bag along with my other hiking items. 5 watts USB from a high and interference-free location is often much better than a suburban high-power base station. Don't take my word for it, try it No 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. Read my review of it. RX Frequency Coverage: 100 kHz - 56 MHz; 76 - 154 MHz; 420 - 470 MHz. (Exact frequency range may be slightly different) This might not be what you want to hear, if you are not a fan of CW. 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. For years I resented the need to learn CW and never used it after I passed the test - until I got interested in QRP and realized the benefits of it. Becoming competent at CW can be hard, but it really repays the effort. If you aren't there yet, I have a couple of programs that will help you get your speed up. MorseGen is the ideal code practice generator, while if you want learning to be a bit more fun, to give you more incentive to practice regularly try MorseTest. CW filter

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. The FT-817 is stable enough for casual HF operating but could be even more stable. Better stability is desirable if you operate frequency critical digital modes or 70cm SSB where variations become significant.

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. conditions. To see how low you can go you need an RF attenuator. Try it and see what you can do with 20 milliwatts or less. I've had good results from sealed lead acid (cheap but heavy), NiMH and, more recently, LiFePO4 battery types.
