FT-817 The Ultimate Backpacker!
Multi-mode Portable Transceiver

The world’s first self-contained, battery-powered, Multi-mode Portable Transceiver covering the HF, VHF, and UHF bands!

For more than four decades, Yaesu has been a world leader in the design and manufacture of high-performance multi-mode base station and mobile transceivers, as well as FM handhelds.Yaesu broke new ground with the introduction of the FT-817: the world’s first HF/VHF/UHF self-contained battery-powered Multi-mode Portable Transceiver. Providing up to five watts of power output, the FT-817 is designed for operation on the 160-10 meter HF bands, plus the 6 meter, 2 meter, and 70 cm bands. Whether your preferred operating mode is SSB, CW, AM, FM, Packet, or SSB-based Digital modes like PSK31, the FT-817 is ready to join you on your next hiking, camping, or search-and-rescue adventure!

Now the 817 legacy is even better with the introduction of the FT-817ND, which includes coverage of the U.S. 60-meter (5 MHz) band, and it also includes  a 1400 mAh NiMH Battery pack (FNB-85) and NC-72B Charger!




Ultra Compact HF/VHF/UHF Multimode Rig
Despite its incredibly small size (5.3" x 1.5" x 6.5"), the FT-817 delivers big performance! Its next-generagion PA puts out five watts on all HF bands, plus the 50 MHz, 144 MHz, and 430 MHz bands, on all popular operating modes: USB/LSB/CW/AM/FM/Packet/PSK-31/RTTY.
Wide Receiver Frequency Coverage
Enjoy shortwave and FM broadcasts, public safety communications, and airband calls thanks to the extended frequency coverage of the FT-817ND, which includes reception on 100 kHz - 56 MHz, 76 - 108 MHz (W-FM only), 108 - 154 MHz, and 420 - 470 MHz.
Two Antenna Connectors for Ease of Installation
The front panel includes a convenient BNC connector for attachment of a whip or VHF/UHF rubber flex antenna (supplied). The rear panel includes a type “M” (“SO-239”) connector.

As shipped from the factory, the BNC jack is active on 50/144/430 MHz, while the “M” connector is active on HF. But using the Menu, you can assign, for example, 50 and 144 MHz to the rear panel, if your coaxial cables have matching plugs.
Receiver Enahncement Features
• IF Shift – For reduction of adjacent-frequency interference.
• IF Noise Blanker – For reduction of ignition and other impulse-type noise.
• IPO (Intercept Point Optimization) – Bypasses RX Preamp on HF/50
MHz for improved performance during strong-signal conditions.
• ATT (Front End Attenuator) – For more pleasant reception of very
strong signals.
Outstanding CW Features
• CW “Semi Break-in,” with T/R recovery delay programmable from 10
ms ~ 2500 ms. At 10 ms setting, performance emulates QSK
operation.
• CW Reverse: provides BFO injection from LSB-side, instead of default
USB-side.
• CW Pitch Control: adjusts TX offset and (identical) sidetone between
300 Hz and 1000 Hz in 50 Hz steps; this allows precise spotting on DX
stations. Sidetone level is adjustable.
• Built-in Electronic Keyer, with speed adjustable between 4 WPM and
60 WPM, and Weight (Dot:Dash Ratio) adjustable between 1:2.5 and
1:4.5.
• For emergency use, the Menu allows you to set up the Microphone’s
[UP] and [DWN] keys for generation of “Dots” and “Dashes” on CW!
Versatile, Easy-To-See Liquid Crystal Display (LCD)
A wealth of information is available on the front panel LCD:

• When you have to be away from the radio for a few minutes, but
would like a visual indication of activity while you’re away, activate the Spectrum Scope Monitor. The Spectrum Scope Monitor allows you to watch activity ±5 channels from the current operating frequency.
• The LCD illumination color may be set to either Blue or Amber color, using the Menu.
• Watch for low battery trouble using the Battery Voltage Meter display selection.
• For ease of viewing while outdoors, you can double the size of the
frequency display
High Performance Collins® Mechanical Filter Options
An optional filter slot is provided in the FT-817ND, allowing the owner to install one of two available Collins® Mechanical Filters. For CW operation, choose the 7-pole YF-122C (500 Hz bandwidth), or for very natural-sounding SSB select the 10-pole YF-122S (2.3 kHz bandwidth).
Internal Battery Power
The FT-817 is the only rig in its class with internal battery operation capability. Shipped from the factory with a battery tray for 8 "AA" batteries, the FT-817D may also be operated from the optional FNB-85 battery pack. full power output is available under battery power.

Other manufacturers radios make you carry around a heavy external power source. . .but the FT-817ND is entirely self-contained, making it ideal for backpacking or search-and-rescue work.

Reviews For: Yaesu FT-817

N0AHRating: 2020-04-24
CPU seems possessed Time Owned: more than 12 months.
So this radio looks like a transceiver but acts like a toy. My problems with this rig started 4 years ago when we took it out of the box- the battery sucked. The brand new battery sucks I got from HRO last month. Or is the rig just sucking it out through holes? The display in a mobile sr up is tiny and is difficult to read. The controls are jammed together making it difficult to solve any common issue while driving. The receiver is excellent- but HF operations are a real bust due to poor selectivity. Everything seems to cause QRM. Do not get burned buying this radio. I guess the upgrade has solved some issues, but I keep spending money trying to put lipstick on a pig. I am very frustrated. This in my mind was suppose to be a great back up rig or one easy to take out of the car for mobile operations. Bottom line, if HRO is selling me a new battery and it cant get the rig to even stay on for more than 3 hours, or the one that came with it never worked, I guess it is a worthless radio. I have the programming software but it is a waste of time since the CPU can't remember it- or just acts up like control button freezing, the rig getting stuck in TX on some bands, while being on RX as it should be on others. I have over a hundred reviews on e-ham. This by far is the most scathing I have ever written. My advice is do not waste your money on a radio you have spend much more on finding an outside source for a battery that works. Anything from Yaesu is just them dumping crap-

Swiss Army Knife of QRP radios...Time Owned: more than 12 months.
The radio deserves a rating of 5 except for the fact I had to replace the PA module for something I feel is a design problem.

I left the NiMH battery pack in the radio for several weeks of non-use without a DC PS actively connected with the radio "off". To my dismay the PA was only transmitting at only half of its normal RF output power (3dB less RF output, down to 2.5W---arrgh...one PA device blown) This was due to the fact that the battery pack always remains connected to the PA module. The PA module slowly drains the pack whilst the radio is "off" and not connected to external DC. When the pack's DC Voltage drops to less than 6 Volts or so, the PA module goes into oscillation and kills one or both of the PA transistors. Apparently (but not to me) this is a documented and well known failure mode for the plain, vanilla FT-817.

$60 for Yaesu to ship me a replacement (with the newer PA transistors) and a bit of work later, I had my 817 working as good as before. The upgraded PA (which also fits the ND model) is supposed to be immune to this failure mode. I don't trust it, so I leave the battery pack out unless I plan to go portable (almost never).

That said, I still love the radio. I bought it and its companion FT-817ND both used. I use them individually for portable HF QRP with a SuperAntenna and together to work the ham satellites with an Arrow yagi.

Both units are upgraded with cranker knobs, flip down peg legs, CW filters, and the Chinese ripoff version of the TCXO-9. The ND also has a WindCamp battery pack (which wisely has the disconnect switch built into it).

Yaesu was ahead of its time with this radio. That's why the 818 is still selling well.

Timeless...

So much fun - such a small packageTime Owned: more than 12 months.
I bought this radio used several years ago. And it still astounds me how much this radio does in such a small package. It could easily be your only radio.

It isn't the best at anything, but it does everything, and does it quite well. And I dare you to sling an FT-5000 over your shoulder and carry it out into the field, much less all the batteries you'd need to run an FT-5000.

Radio-wise, it's a combination of a swiss army knife and a leatherman tool all rolled into one neat little package. 160 meters through 70 centimeters, ALL modes, 5 watts. I did add a CW filter to it, which makes all the difference in the world when operating CW.

My only regret is that I waited so long to actually buy one. I do know that I never want to be without an FT-817. If mine ever dies, I'll replace it immediately with an FT-818ND. There isn't another QRP rig out there with the fit, finish, function, and ruggedness of an FT-817.

If there is one thing I'd really add to this rig, it's a zero beat tuning indicator for CW like the FT-857D has.

It case you haven't realized by now, I absolutely love this little radio!
AB0ORating: 2018-12-08
Very nice rig!Time Owned: more than 12 months.
Owned this rig since 2002, so probably fitting to review at this time.
This has been my trusty portable rig all those years, and I had a chance to look at the new 818 recently...see no big changes or concerns.
I have operated my 817 in a variety of ways and setups...
a) Packpack, bicycle, and other portable with both the internal battery and an external battery. The internal battery is limited, but convenient.
b) Base station with the MFJ power supply and the LDG Z-100 autotuner (if needed)
c) Mobile, powered from the car power and using a hamstick

I installed the BHI DSP internal unit in 2007 which was a worthwhile addition.

The receiver is quite good, and operating portable with a buddipole provides good signals, R and T, even on current bands conditions. I play portable HF with a friend who uses a KX3 and I can hear and work any station he can work. Simple as that.

I owned the 857D as well (bought them on the same day), and the software is virtually the same, but the 857D consumes far too much current on Rx to qualify as a portable rig.

I looked at the KX2 and KX3, but hesitate to give up the all-band feature.

I would likely give the 818 a try if I needed to replace my 817.

My 2nd One and Enjoying it Even MoreTime Owned: more than 12 months.
Although I wrote a review back in 2005 on my first FT-817ND, I figure I'm allowed to do another review since I bought another FT-817ND! I gave my first FT-817ND to my son so he would have get-away radio package since he is our county ARES EC. However, after a few years of playing with several different big desktop radios since then, I once again was yearning for a good, throw-it-in-the-briefcase radio for travel fun. Needless to say the FT-817ND was first choice so I bought one again.

I feel like I've rediscovered the fun of low power portable. Currently however, I'm still just using my new one in the home shack in lieu of my desktop regulars (FT-991A and Icom 7600). I love it's simplicity and great audio. The FT-817ND is such a good basic radio that has all you really need to work most modes. It is unmatched when you want HF,VHF and UHF, and SSB, CW and digital all in one box.

Those who have faulted the FT-817 for shortcomings are simply missing the point. Pick 2 of these 3 feature sets: 1) Small and lightweight yet good TX and RX performance, 2) all band/all mode, and 3) low power consumption. You won't find another rig that does all 3 as well as the FT-897ND. More modern DSP and SDR-based radios don't really compete in all 3 feature sets/ This will be a classic rig for years to come. Maybe my grandson will like to inherit this one from granddad!

Earlier 5-star review posted by K4TB on 2005-05-04

I've had my FT817ND for just a few weeks and I really enjoy it. Worked 16 countries so far with 5 watts and not really trying (my Tennedyne 6-element log periodic at 45' gets some of the credit of course).

Yaesu did a really nice job with the menu and features and I am impressed at how much high tech is crammed into such a small package. Inside it is a really clean simply-looking layout however.

I travel a bit and the radio fits into my luggage quite nicely, yet it plays as well as many full-size rigs. I picked it over other QRP rigs like the IC703 because it also packs 2m and 70cm and has an internal battery. At least while traveling, even if I can't put up a decent HF antenna in the hotel, I can still work local VHF and UHF. It's also a good IF rig for some of the microwave and satellite work I do. I've never seen so much versatility in any package so small; it's amazing!

The narrow CW filter is a must but the IF shift and other adjustments make it possible to do without the narrow filter often. I bought the TXCO but am still evaluating whether I really needed it - the stock oscillator is pretty accurate and stable. You will want to buy the soft case if you carry the rig around a lot.

So much to do with this thing! I have the remote control software but haven't even had time to play with that yet. My IC756 is collecting dust while I enjoy this FT817ND in my base station setup. I'm impressed.

Yaesu FT-817

The Yaesu FT-817 is one of the smallest MF/HF/VHF/UHF multimode general-coverage amateur radiotransceivers. The set is built by the JapaneseVertex Standard Corporation and is sold under the Yaesu brand.[1][2] With internal battery pack, on board keyer, its all mode/all band capability and flexible antenna, the set is particularly well suited for portable use. The FT-817 is based on a similar circuit architecture as Yaesu's FT-857 and FT-897, so it is a compromise transceiver and incorporates its features to its low price ($670.- at its 2001 release).[3]

The upgraded FT-817(N)D was launched in 2004. The difference between the two models is the addition of 60 meter band coverage in 5 fixed channels (USA model only), other display lighting options, modifications in the RF stage, the included FNB-85 battery-pack and NC-72B charger.

The FT-817 is a QRP transceiver.[4]

Technical description[edit]

CAT interface[edit]

A serial port with a wide range of commands is provided.[2]

Circuit description[edit]

The following circuit description is an extract from the service manual[5]

RX signals may be input via a front BNC connector or a rear UHF SO-239 connector (Yaesu calls it a type "M" connector) using a relay on the PA unit. The selection has to be made per band (HF, 6, 2 m or 70 cm) using menu selection. The BNC connector is the antenna connector chosen when the relay is bypassed.

A 70cm signal path goes through a high pass filter network, through the RF directional coupler/power detector (not on rx) to a low pass filter to a PIN-diode. In rx mode, these are turned off. The rx signal then passes through a DAN235U; this is a dual diode and when in UHF rx mode, the appropriate diode is turned on, passing the 70 cm signal through and the signal then leaves the PA board. On the MAIN circuit board the 70 cm rx signal enters a DAP236U. This dual diode get its current from the PA unit and when 70 cm rx mode is active one of the diodes is turned on. Rx signal goes through a device consisting of 2 back-to-back diodes providing protection for the receiver's front end. The output of the preamplifier is sent to a helical resonator filter. The output of the filtered and amplified 70 cm path is passed through and coupled into the receive mixer. For 70 cm receive, PIN diode bias is provided to the PA unit, through the MAIN unit and then through an RF-decoupler network, a parallel-output shift register.

A 2m signal goes to a relay and then the signals are diplexed, with 2m and < going to a lo-pass filter. The signal gets diplexed again using a hi-pass filter, separating out the 2 m signal from the HF-6 meter signal path. The rx signal passes through the VHF directional coupler/power detector (not used in rx) to a lo-pass filter and then passes by 2 PIN diodes (both HSU277). These diodes and related components form T/R isolation switches that operate similar to that of the 70 cm front end. Rx signal passes through the half which is not used for 70 cm and then to the RX RF output and is then passes to the MAIN unit. Here the signal enters and then passes through a transformer, along with a varactor and related components and forms an electrically-tuned filter/matching network, the 2 meter preamplifier. The output of the preamplifier goes through 2 electronically tuned transistors. Finally, the output goes through to get to the rx mixer. For 2 m rx, the PIN diode bias is provided by the PA unit to 2 m preamplifier.

Aircraft band Rx path (108-154 MHz) is the same as that of the 2 m path on the PA unit. On the MAIN unit, it goes through the same part as the 2 m signal, but it then goes through the diode portion that was not used for 2 m into an electronically tuned bandpass filter. The output passes through the rx mixer. The PIN diode bias is provided by the PA unit and flows through the primary transistor. On the output, current is provided and goes through the secondary transistor. Both current paths are completed using the aircraft band rx preamplifier.

WFM broadcast band rx path (76-108 MHz) is identical to the 2 m path on the PA unit. On the MAIN unit it passes through the same portion as the 2 m signal, then through a HSC277 diode. This signal then goes into pin 10 of a Sony CXA1611 FM Receiver IC. The IC has a front end, mixer, IF and demodulation and provides received audio. In order to suppress local oscillator leakage and provide a slight amount of image rejection, a varactor and a coil provide one stage of tracking bandpass filtering. Typical for single-chip receivers, the dynamic range of this receiver is poor. When using a large antenna, expect overload/intermod problems.

HF and 6 meter receive path. After relay the signal is diplexed via a low-pass filter. At this point 2 m, aircraft and WFM are diplexed. Continuing the signal passes through a low pass filter, continues through the RF Directional Coupler/Power Detector (not used in rx) through low pass filters selected by relays as appropriate for current rx frequency. The combination of lo- and hi-pass filters provide broadband bandpass filtering to the rx front end. For 6 m the hi-pass filter includes a preamplifier (always used on 6 m rx and not affected by the IPO menu setting). The appropriate high pass filter output is selected with a PIN diode with logic levels. The output from the PIN diodes are routed to the MAIN unit. Here the rx signal is applied to dual PIN diode modules (type DAP236U). One path routes the signal directly between the two modules and the other path passes the signal through a 10 db pad - the pad that is switched in as a menu item. The output is then passed through a simple lo-pass filter to another DAP236U. One of the outputs is applied to a preamplifier and the other is applied to a diode, bypassing the preamplifier. The output of the diode is applied to an IF trap. The purpose of which is to prevent 68.33 MHz energy from the antenna from getting into the 1st IF. The HF receive signal is routed to the receive mixer.

Known weaknesses[edit]

Vulnerable final transistors in non-ND model! The 2SK2975 FET's in the final stage are VERY sensitive and can easily be destroyed by high SWR, overheating, overvoltage, or voltage peaks. In the ND model Yaesu (Vertex) replaced the FETs with RD07MVS1 FET's but the problem may still exist. Be aware that the RF stage may remain sensitive to damage.[6]

The internal battery should be removed if the radio is to be stored for an extended period. In the non-ND model, a failing battery can cause the finals to oscillate which destroys the FETs. This was corrected with the ND model though it is still recommended that the internal battery be removed for extended storage to prevent this issue as well as to ensure that there is no possibility of battery leakage which can destroy internal components of the radio.

Misha sat down and began to pull off my jeans that I had already unbuttoned. I looked at him, smiling, I liked him more and more. Pulling the jeans off me with my help, Misha kissed my pubis through white panties. I also slowly pulled my panties off me and was already kissing my pubic hair, clean from the hairs.

His tongue immediately licked my lips, I moaned and spread my legs so that he could penetrate my pussy with his tongue.

All her thoughts, and her whole world were now focused on pain and pleasure, on a burning shame and a sweet, viscous sensation in the lower abdomen. Her pussy throbbed from the inside out and she knew she was as wet and bloated as possible now. She could feel her juices trickling down her thighs.
