Opinions regarding Yaesu FT-817ND transceiver?

Seems like a great little rig, blasts out a whooping 2 watts
of RF power on batteries, do not know if I can handle
that much power, if I decide to apply for another license.

I was W6TAM 55 years ago. (extra-class license)

I have not really shopped around for a rig yet, so do not
know how the Yaesu FT-817ND rig compares to
its competitors in the $700 price range.

Any advice gratefully appreciated -

I don't have one, though I have the 817's bigger brothers the 857D and
897D.

Two of my friends *do* have 817s, and _LOVE_ them.

Yeah, they are cute little buggers. Here, we are all way beyond
cell-phone range, so a few hams sprinkled around here can do a
lot of good in an emergency.

I will check out the 857D and 897D, just to make sure I have
covered all the bases; thanks for mentioning those models.

The original 817 had a problem with batteries. The off switch did not
actually turn off the power and the finals being able to function
from 1.8mHz to 450 mHz went into oscilation and burned out.

Has this been fixed? The popular fix at the time was to remove the batteries
when the rig was not in use.

The biggest problem with the Yaseu is the tiny screen. The ICOM 703 has a
much larger screen. The 703 only goes up to 6m though.

The 706 does have the same frequency coverage as the Yaseu. You can adjust the
output power down to 5 watts, so it may be a viable option. It also has
a more features than the Yaesu.

If you are using it in a location where size and weight don't matter that
much and nor does the increased battery drain, it may be worth the
money for it so that you have 100 watt HF output if you need it.

The ICOM rigs include a removable front panel, so you can mount them
elsewhere and just have the control head at your operating position.

Looking at Universal radio the current price for a new rig is
$600 for the 817ND, $730 for the 703+ and $945 for the 706IIG.
So you have a big range of price, power and features to choose from.

The Yaesu is the grandson of the FT-290 and simlar rigs, which were
portable VHF/UHF multimode rigs, while the ICOM grew out of shrunken
HF rigs, the Kenwood TS-50 being the first. Surprisingly, Kenwood no
longer has anything to offer in that line.

Thanks for the comprehensive rundown, I will check them all.

Regular telephone service in these mountains of northern CA
is unreliable, quite a few older folks here are in a real pickle
when the phones go out.

That is one of the reasons I decided to reactivate my ham ticket.

Main reason of course is just out-and-out fun

I haven't got a '817... I instead opted for its 100W cousin, the
'897D. The catch with all of these more modern "all-band" radios
though, is the high level of integration. While it does shrink the
size, it does mean the radio is more complex -- and thus repairs will
be more expensive and difficult.

In my case, I'm waiting to hear from the insurance company about
whether they'll cover the replacement of my set following lightning
damage that took out a few diodes in the power section, fried the
microphone preamp and finally nuked a DDS chip responsible for
generating the carrier sidetone. The end result is a radio that at
first, would not run off external power (this has been fixed), won't
demodulate SSB (sounds like an AM receiver with the volume turned
down), won't transmit AM/SSB/CW, and won't modulate a FM carrier. Due
to the usage of multi-layer PCBs, it's impossible to fix tracks that
may be damaged within the layers of the PCB... and the DDS chip in
question is no longer manufactured or supported. In short, a write-
off.

The lightning struck a tree in the neighbour's back yard, the
resulting earth potential rise caused the above damage, as well as
cooking some network equipment in our house, another neighbour's
computer, and several electrical goods within the property where the
strike occurred. So the old wisdom of unplugging everything is
especially true for the modern rigs -- not just the antenna, but
station earth and power as well!

Apart from this, they are great radios. Mine was brilliant, and I
hope to get it replaced at some stage. Interestingly, on 2m SSB, I
find my FT-290R II (with 25W linear) outperforms it on occasions, but
given the capabilities of the '897, it's worth the money. I dare say
the '817 is in much the same league, and are very popular amongst
microwave enthusiasts as they are all-mode and low-enough power to not
fry the backside out of transverters.

Thanks for your comprehensive post on "all band" radios.

Sorry about the lightning frying your expensive rig; here I have
the same problems with lightning, came to the same conclusion
as you did, namely completely unplug _ALL_ leads to my rig.



I have not yet decided which way to jump as regards buying
a rig after my long 55 year absence from ham radio:

1) Completely portable (ordinary alkaline battery powered)
very low powered rig such as the Yaesu FT-817ND

2) Larger 100 watt mobile rig such as the Elecraft K3
or the Yaesu 897D

The Yaesu 897D certainly has impressive spec's


Presently I do not have enough smarts to make an intelligent
choice between the Yaesu 897D as compared to the more
expensive Elecraft K3, when it comes to the fine points
of both those rigs.

With the Elecraft, I lose the mobile capability, however
Elecraft advocates are very impressed with that fine rig.

Decisions, decisions... g

The 897 will accommodate two battery packs and (or is it _or_?) a built-in
power supply. They're on my purchase list -- after we get the tax refund or
when I win the lottery.

The Yaesu 897D certainly has impressive spec's

Enough so that I have, and use, two of them. In their price class, they are
very impressive radios. I just swapped my Yaesu FT-450AT for one yesterday,
and that rig got K7SDW on 20 m with 10W output CW yesterday afternoon,
first crack off the bat.

Presently I do not have enough smarts to make an intelligent
choice between the Yaesu 897D as compared to the more
expensive Elecraft K3, when it comes to the fine points
of both those rigs.

I suspect that the K3 is, overall, the better radio, though it doesn't do
70 cm. At least it doesn't do 70 cm _yet_; I suspect a 70cm transverter
board is in the works, though I have no hard info on that. I'll get one
when I win the lottery.

With the Elecraft, I lose the mobile capability, however
Elecraft advocates are very impressed with that fine rig.

I've certainly read rave reviews on the K3. Acquisition is dependent on
coming into a sizeable bolus of cash, though. I'd also like to have a
Flex 5000 to play with, and an Icom 7[678]00, and a KW TS-2000, and a
Yaesu FT-2000, and some W-J or Cubic receivers, and ... .

Decisions, decisions... g

Yeah, but not the kind that hurt.

The Elecraft K3 seems to have one of the best RF front ends currently
available on an amateur radio. It does extremely well at pulling in a
weak signal, when there are very strong signals on nearby frequencies.
If you're into contesting, DX, or Field Day competition, this looks
like radio to have.

For what's worth - the FD-857D is almost the same as the FT-897D in
most respects - just in a smaller package. These two radios give you
2-meter and 440 capability, in addition to HF and 6 meters.

He he... yeah... I've gone one step further -- using solar and
batteries to power my radios now. So that's one less bit of wire that
lightning can come in on. The experience has taught me the diligence
to unplug the rest.

Indeed. I haven't looked at any of the Elecraft radios, my decision
was between the Icom IC-706MkII G, the Yaesu FT-857D and Yaesu
FT-897D. I wound up going for the latter because above all, I wanted
a radio that I could take with me portable, or stick in the rear
basket/luggage rack on my bike for bicycle mobile operation.

I rejected the Icom in the end on two grounds:
(1) Having used one during last year's JOTA... I found it difficult to
access what I considered, very rudimentary controls. I found its
menus awkward to use. I dare say it'd be better if I had the time to
read the manual more carefully, but that was my experience.
(2) Its small size meant it could not efficiently dissipate heat.
This meant the radio was prone to overheating problems. (I suspect
the FT857 would suffer this too.)

The '897 had two nice features: I could embed two batteries inside
with a combined 9Ah capacity, and there were two auto-tuners on the
market that could bolt onto the side. So I'd be able to pick up one
unit, and have almost a complete radio station -- just add antenna and
microphone. For the antenna, a squid pole works nicely, can be set up
almost anywhere and is lightweight. A dipole is also pretty easy to
carry and set up. So for a portable rig, the '897 was ideal.

My only gripe is that Yaesu for some reason decided that it would use
NiMH cells in its battery packs... Li-ion would have been lighter and
higher density. Heaven forbid, gel-cell batteries would do better
than NiMH! But that's the choice they went with, and we all have to
live with it.

I think the real questions a
(1) How often are you going to use it portable/mobile? (For me, I'd
was using my '897D portable at least once a week... and when my
handheld died -- I was using it mobile daily -- even on public
transport.)
(2) What bands are you likely to use? The K3 offers up to 6m with a
2m option, the '897D offers up to 70cm as standard. (I use 2m a _lot_)

I agree that we have to try to anticipate our needs.

The all-in-one rigs offer *so* many great features that it is
downright befuddling trying to take advantage of all the features,
in one lifetime.


In the end, emotions and expectations affect a lot of us when it
comes to these purchases, rather than hard facts.


However, I *will* say that rig performance in a crowded band
can reveal a lot about the quality of one rig versus another.

That is why I have an emotional attachment to QRP rigs,
particularly CW QRP rigs, using exotic methods to fish out very
weak signals in a crowded environment. Fun, fun, fun.


I expect it is a lot more difficult to fish out a weak SSB signal. g

Wonder if any hams are experimenting with liquid nitrogen cooled
RF front ends to their rigs, to reduce thermal noise.



Getting back to reality for a moment, I have almost decided to base
my personal choice on whatever rig has the best receiver for weak
CW signals, in a crowded band.

If all rigs are essentially equal in this respect, then I get to
consider _other_ aspects of their performance.


If one rig stands out head and shoulders above others for CW work,
then I would be strongly tempted to favor that rig.

(assuming of course diversity antennas to minimize fading)

Playing with CW is just a personal choice, in my case.
