No obscenities, discriminatory, abusive, or other content not suitable in public or for younger readers. The processor replaces the standard microphone element with an electret type that has more of a treble emphasis. This may not suit all voices but it can enhance copy under difficult conditions, compared to the normal Yaesu rather muffled audio. I think it sounds excellent on FM, too. Wonder Wand Wonder Loop 750 Portable Loop Antenna is a Superb compact QRP portable loop perfect for attaching directly to your ft-817 or QRP transceiv... One question that sprang to mind after getting the 12V switched mode PSU was: would using a 12V supply affect the battery charging function of the FT-817? Would the batteries need to be charged for longer? Would the voltage be sufficient to charge the batteries at all?

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. The Yaesu ft-817 leather case For those who want to protect their radios when operating portable, there is the optional CSC-83 carry case. Cut-outs ar...

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.

I might look at this once my 2.5Ah LIPO that I have in my 817 gives up (they tend to last about 2.5 years I have found (at my usage level)). Battery technology has advanced since 2000. You can now get internal batteries with significantly more capacity than 600mA/h. This video is an example with 2450 mAH NiMH types.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. 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 CW Do not submit a product review critiquing another review or reviewer. Reviewers should be able to share their product opinion without being publicly criticized. 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

This will charge the above batteries (and other Lithium cells and NiMH and NiCd etc.) Hobbyking Radio Control Planes, Drones, Cars, FPV, Quadcopters and more - Hobbyking There really is no right answer to this question. Also, each and every one of us has a different requirement. So, what we really need to do first, is answer a few questions. The only thing I might add, is that the main connectors on the battery you may wish to swap to powerpoles or the like as I’m not a fan of the ones that come as standard. Seems a little easy to get a short on them. You probably do want an external charge connector so that you can balance the cells from time to time, and possibly charge them faster than the FT-817 can. But I see no harm in letting the radio charge them. It will provide a useful and convenient top-up charge. Clearly you mustn’t use both charging methods at the same time (I presume this is why the battery tray that started this thread provides a switch).

Thoughts on the FT-817

To use CW with the FT-817 you need to install the optional CW filter. The standard filter is too wide, so you hear too many other signals and noise, making it hard to copy any other than the strongest signal in the passband. 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 can decode (and who decodes you). Or if you wish to send pictures slow scan TV has mobile phone apps that you can use in conjunction with an FT-817/FT-818. If you just need a program to help you manage the memories in the FT-817, then I suggest that you try 817-Mem, written by F5BUD. A portable power supply possible if you use the right antenna such as a well-built magnetic loop or vertical. The video shows working a contest on 40 and 20 metres with a lightweight 90cm loop.
