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. Do not submit a product review critiquing another review or reviewer. Reviewers should be able to share their product opinion without being publicly criticized. Some form of digital modes interface between your FT-817/FT-818 and phone / computer. Build or buy, eg this one for Android phones Even when band conditions are tough on SSB or a major contest makes competition fierce, refuge can often be sought on the digital modes. A valid product review is one where you have experience or knowledge of the product that you would like to share with others.

if the island is a separate IOTA group to where you normally live you may attract the attention of IOTA chasers. 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. 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 itactivity. It educates you about other spectrum users, teaches propagation and you'll probably hear some interesting communications that makes it worthwhile. 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 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.

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! 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. 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.Personally I prefer 500 Hz as I'm in Australia and the bands are fairly quiet. But those in more densely populated areas might got for a narrower (250 Hz) filter. Installation ie easy and requires no soldering. 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 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.

Especially when the bands are crowded, operating CW with a standard FT-817/FT-818 can be a trying experience. A CW filter can make a great improvement to reception. Filtering can either be done in the receiver's audio 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. To be sure of being able to transmit from anywhere you take the lot - transceiver, battery antenna coupler, mast and wire. But it can be fun (and lighter) to just take the rig, battery preferred as some of the earlier '817s blew their final amplifiers. You can recognise an ND model by its choice ofand doesn't give much 'headroom' when the battery voltage drops. Whereas too high a voltage (14 - 16 volts) is inefficient because of higher current consumption for no more transmitter output. Optimum is To make the most of the enhanced conditions put together a portable 'grab and go' station so you can be out pedestrian mobile at a moment's notice. This includes your FT-817/FT-818, a battery suitable for 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. RX Frequency Coverage: 100 kHz - 56 MHz; 76 - 154 MHz; 420 - 470 MHz. (Exact frequency range may be slightly different) 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

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. Products to be reviewed typically should be tangible ham radio related items such as radios, antennas, towers, test equipment, feedlines, etc. 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? 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..

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. One possibility is an audio processor such as the "One BIG Punch" from W4RT. I haven't tried it, and it's not an option I would choose. Audio processing can actually end up making your speech less intelligible, because it produces in-band distortion products. Put simply, if you clip a 400Hz signal, it creates harmonics at 800Hz, 1200Hz and so-on. RF Speech Processor 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. The design calls for protected 18650s to be used. 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). 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.
