Replacement battery for YAESU FT-817

Product Information

The difference doesn't look that great. That's partly because the AGC in the receiver used to make the recording has brought the signals up to a similar level. But you can see that there is less difference between peaks and minimums in the compressed oscillogram. Each syllable looks (and sounds) clearer.

I have not yet tried it, but 3400 mAh with the ability to charge it in 1 - 2 hours sounds like something. 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. What is not apparent from this is that the compressed transmission is narrower and cleaner. That's because without the compressor, the FT-817's ALC is providing the compression. I have done what most FT-817 owners probably do, and turned the SSB mike level up to get a louder signal, at the cost of a bit of splatter. The RF compressor cleanly reduces the peaks, as well as bringing the lower levels up, so the ALC doesn't have to work so hard. The end result is a louder but cleaner signal. Whether that's worth the cost is your decision. Working CWI'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? 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. First, because the cell is LIPO, it has a separate charger and a separate charge power input, and the manual rightfully strongly advises against using the NiMH charger.. Now for any of you who have watched my YouTube channel, or read this blog, you already know the answer I’m going to give. Lithium Iron Phosphate! Even though you know that’s the answer, you also know that it’s not always the right answer. So let’s go through three different options, and explain the pros and cons of each of them. I agree with Ignacio, I’ve been running my FT817 with 3S lipo batteries without an issue. I have two at around 2.2Ah and a larger one.

An alternative is to use an external battery. That's bulkier but you get more flexibility with battery types. A good bag can help greatly so its carrying doesn't become a chore. Describe your experience with the Windcamp 3000mah lithium battery kit for yaesu ft-817 and tell us why activity. It educates you about other spectrum users, teaches propagation and you'll probably hear some interesting communications that makes it worthwhile.The FT-817/FT-818's internal microphone is OK but not great. And if you're running low power you want the punchiest transmit audio possible. So have you used the 3D Printed, 18650-filled version that is featured at the top of this forum? I did see that I could buy like a windcamp lipo that fits there fine, but I like the idea of using 18650s because I have a pile of them. 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 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.

RX Frequency Coverage: 100 kHz - 56 MHz; 76 - 154 MHz; 420 - 470 MHz. (Exact frequency range may be slightly different) Poor receiver. 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. Even using an inefficient short whip, strong local stations can overload it. The main problem seems to be bleedover (apologies for the CB term, but it sounds just like a cheap CB radio) due to the inadequate IF filter fitted. A better filter is available as a (pretty expensive) option, but you can only fit one accessory filter, which is a problem if you want a narrow filter for CW. Overall I give Yaesu only 7 out of 10 for this radio, with the comment "could do better." But there's nothing else quite like it on the market at the moment. If you want a very small all mode HF and VHF radio, better get an FT-817! 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. The Wideband QRP Portable Antenna System. The latest design from the masters of rig-placed Wideband antennas. The Wideband is a compact Antenna coveri...My FT-817 sits quite happily on top of my Maplin 3A power supply and looks as if it was made for it. Unfortunately, the magnetic field from the mains transformer affects the 817's VFO, giving a "dirty" note to signals. The power supply is also twice as high and about 4 times as heavy as the FT-817, making it not something you really want to carry around on trips. I thought I would try to find something smaller and lighter. It is possible to work SSB DX using a barefoot FT-817, even with modest antennas. However, it certainly helps to pay attention to your transmitted audio, to maximize your chances of being copied when you are down in the noise or competing with higher-powered QRM. A speech processor will give your SSB signal valuable extra "punch". 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.
