There are three models. The early FT-817, the later FT-817ND and the much later FT-818. There's not a lot of difference between them. However the ND model is Proven quality, certified safety: Yaesu FT-817 FNB-72 replacement batteries for up to 1000 charging cycles My portable operating sessions are typically 2 to 3 hours. Sometimes up to 4 or 5 hours if it's a field day contest. It's worth doing a power budget but generally you're looking at a 4 to 8 Ah battery capacity. Note that a special crimp tool is required to install the pins terminals/pins properly, but like most crimp-type connectors it may be possible to do some very careful soldering and "manual" crimping to make a reliable electrical and mechanical connection. 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..

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 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". Products to be reviewed typically should be tangible ham radio related items such as radios, antennas, towers, test equipment, feedlines, etc. 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. Portability is a great feature of the FT-817/FT-818, but few enjoy it to its full advantage. A great way you can do this is to operate HF pedestrian mobile. Despite the FT-817/FT-818's low power some great results arePoor 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. Poor ergonomics. Many commonly used functions are accessed from one of the three buttons below the display, which have about 11 different sets of functions. This means a lot of button pressing and knob twiddling just to do something like turn the noise blanker on or off, change the output power or toggle the meter between SWR and power out. Although to a great extent this problem is inevitable given the small size of the 817's front panel, I'm sure Yaesu could have fitted a slightly bigger LCD panel, with less of a surround, and this could at least allow the current selection of the three buttons to be permanently displayed. Perhaps some functions could have been made accessible from a key-pad mike, as well? Direct frequency input would have been nice. 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.

Battery for Yaesu FT-817/818 - WiMo

I recently received one of these and installed it in my 818 last light. It is now going though a "full time receive" cycle and so far the battary lasts significantly longer - let's see after a few cycles. 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 The good news is that when operating on the 2.5W mode (the default for battery power) the FT-817 appears to deliver the full 2.5W regardless of SWR. I guess this applies to the lower power modes too. if the island is a separate IOTA group to where you normally live you may attract the attention of IOTA chasers.

Working SSB

Bob K6XX identified the problem early and suggests a small changes to the carrier level setting. I made the adjustment as suggested and can confirm it 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. It turned out that the Only 2.5W on battery power. 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.

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.

Finance Available

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. Thorough, comprehensive testing – each battery cell is tested to ensure all safety requirements are met and that it holds and maintains the correct capacity - all before installation Ingnore what some diehard VHF/UHF SSB operators say - the FT-817/FT-818 a perfectly capable performer at these frequencies. preferred as some of the earlier '817s blew their final amplifiers. You can recognise an ND model by its choice of

The most comprehensive computer control program for the FT-817 is FT-817 Commander. This program is the predecessor to Ham Radio Deluxe, but it has many features specific to the FT-817, such as memory management, which HRD does not. Although FT-817 Commander is unsupported, and does not claim to support the FT-817ND, it appears to work, although I have not used it a lot. or intermediate frequency stages. Both work well but the latter is superior when there are a lot of strong signals near the receive frequency. CW filters for several bandwidths are available for the FT-817/FT-818.Certified safety – CE & ROHS certified, Grade A battery with short-circuit, overheating and overvoltage protection Even when band conditions are tough on SSB or a major contest makes competition fierce, refuge can often be sought on the digital modes. All-band" coverage. The FT-817 covers all amateur bands from Top Band to 70cm (excluding the UK-only 4m band and the US-only 222MHz band.) It also has pretty extensive general coverage capabilities. This makes it an ideal "do-anything" radio, suitable for whatever kind of operation you feel like doing.
