Rookie
question here. I under stand the differience to be that on the “D” version the DSP circuitry, is
an standard where as on the standard 857 it’s an option._How would you know
if a 857 had the optional circuitry?, How important or useful is the circuitry?
Thank you for any help anybody can offer!!

The FT-857 didn't originally include the DSP daughterboard, but later on Yaesu included the board with?the radio.? You can determine if the board is installed?by pressing the DSP button next to the power button then pressing one of the three buttons on the bottom of the display (DNR, DNF and DBF).? If the board is installed pressing one of the buttons will display DSP on the top row of the display next to the voltage indicator.

Wow, I didn't know about that feature, I do have the "D" model.
That's good to know. Thanks Larry

The FT-857 series is an amazing rig on a saga proportioned marathon run. It may have been in production longer than any amateur radio transceiver in history, and still going.? Believe it was first introduced about 2001.? I recall a QST review in Nov 2003 of the new "D" model.? One of the distinctions of the non-D model was the ability to do the MARS/CAP modification by the "hidden" menu.? That changed with the "D" model.? My personal FT-857D was among the earliest of the "Ds," has performed flawlessly for over 16 years both mobile (for many years) and in base station with not a single hitch.? Today the panel display has one single pixel wide vatical streak - that's all.? ?It has been MARS modified, added TCXO, YF-122S, YF-122C filters, and replaced the power cord connector with PowerPole.? Brown wire disabled.? Amazing receiver for its time, and operated full break-in CW like a champ.??It joined me in retirement, now resides in a faraday container tucked away just in case.? I take it out every few months for a wake up, and leave on power supply for a day or so then back to storage.? ?Don't mobile anymore, and base station is now an FT-991.? Phil / K4PO

Hello, I do not have a FT-857 but as I understand my FT-897 is the same machine in a new box. So my question is: Do I have FT-897 or FT-897D? I was told the D version has no "D" letter on its face so it is not easy to see the difference...
Waiting for help, Pirx

as I understand it, there is no 897D, the plain 897 is a lower power version of the 857D and has all the same features.

There was an FT-897D.? The FT-897D?is the same as the mobile/portable FT-857D, but has the TCXO-9 high stability oscillator installed.? The TCXO-9 oscillator was an option for the original FT-897.? The TCXO-9 was not included in either the FT-857 or FT-857D, but is available as an optional plug in board.

I got my FT-857 mid 2000. The only places it hasn't been operated is maritime mobile (which will not happen) and portable, which I intend to take care of this summer. I have the IR 2.4KHz filter and have considered the TXCO module and may still install one as I may try FT8 from a picnic table. My unit was mostly mobile with the ATAS-120 which I ditched the included whip for a Larson Kool Rod VHF whip, I lost UHF but that is of no interest to me.I have never had any issues from the rig (touch wood) mostly OP problems, the manual soon sorts that out. I think the FT-101 series may have lasted longer than the FT-857. If a new ham is looking to get one of these rigs, do not modify it in any way and if you want the MARS mod done, get someone knowledgeable to assist you. Other than the filter, I have not touched the inside of my 857, I've no need to, it has provided many hours of enjoyment and as long as I can press the buttons, it will stay with me, also in the shack are an 817 and a FTdx3K. The 857 is a decent all-round rig, marginal for contesting, great for rag chewing and not too bad at DX'ing. It is my longest owned radio ever.

The only difference between the 857 and 897 other than the casing is the 897 has the ability to house a battery for portable ops, circuitry between the two is identical save for the battery circuitry. Same electronic specs, same menu structure, same accessories, same max and min power outputs. The 897 power output drops when fitted with the internal battery, the infamous "brown wire" is used to sense battery power which decreases the maximum power out for both rigs (857 & 897).
In fact, this may add confusion, the 897 and 857 circuitry are the high power version of the 817 except for some differences, the finals for the 817 are the drivers in the 857 and 897.

Sorry Tony, you are not quite correct, not an option, the difference is the 857 came on to the market first, followed a year or two later by the 857D, once the "D" version was available, the non-D version was no longer produced. You are correct however about the difference between the two.
Another thing that reared its head in the USA was that the 857 version aimed at the Japanese market managed to make its way into the US market, it had a maximum power out of 25Watts, this unit was marketed to the Japanese Novice hams as they had/have a power cap of 25 Watts.

Ok, ? I’ll clear up my first submission. ? If I recall, the first FT-857’s, the DSP module was an option, but within a year or 2, it was included in the FT-857’s as standard sales. ? I bought my “857” in 2003 already in production a few years in, with the DSP module included and no longer as an option, it had become standard in the “857” and at that time, without the 60 meter channels in the memory location (60m not available yet in Canada or USA). ? Later, the “D” model came out with the DSP included, and then 60 meter channels in the memory location. ? I still have the original 2003 shipping box without the “D” on it as FT-857. But my later 2017 “D” model does have the “D” included in the model number on the box as FT-857D. But on both radios, production of 14 years apart, both only have FT-857 on them, no “D” in the later model year. Weird huh? ? And yes, there was a Japanese version of lower power ? I should have made myself a little clearer. lol ? ? --------------- Regards, ? Tony VA7TF ?

Nice recovery Tony.
I'm surprised with all the chatter about the 857 and 897, thought all the points and questions were long time put to bed, new blood I guess, good to see the younger crowd getting interested.
Stay safe Tony, perhaps when I get my station set up we can have a chat.

I find the digital filter useful on my FT-857D as I have and continue to receive terrible interference from British Telecom's Open Trash. All the HF bands are wiped out anywhere near a telephone line with their Internet Service Provider over phone twin cables leaking radio crud.
