Reply-To: FT817@...

Happened to me several times (e.g. with the IC-706 ...). Having owned
many many Japanese ham radio FM hand helds since 1975 (my first on
was
the TR-2200G), the only hand-held I have since several years now that
totally fulfills my needs as a frequent traveller is the Yaesu VX-1,
no need for a Mark II.

I'm on my third 706 model, and if they manage to improve it even more,
I'll probably get another.

A "FT-817 Mark II" with full receive (and TX?) capability down to 100
kHz (for the European LF band), narrow FM capability between 76 MHz
and 87.5 MHz and full receive capablity up to 180 MHZ would probably
meet this criteria as well (anybody in JA listening ?).

I'd like to see a synchronous AM detector, and perhaps a second
filter. Even at the expense of the internal battery pack.
Actually, RX and TX coverage of the entire marine band would be great,
since marine radios are used for general communications in many areas
of the world.

But so far I am very happy with the version I have: a great little
radio with a lot of fun build into it.

Mine is serial #2500911, and still has the sharp edge on the pattery
opening, although I'm going to file it off today.

Kinda like the IBM PC110 which handles RT's software nicely, matches
the radio and runs on camcorder battery.... hmmm.

Hello Don & Julian,,
Something I have just tried, maybe because I read it somewhere.
This is part of another message I have just posted.
Rgds -- David

One thing I did try with my 10M Maldol whip,
and the results are interesting..
Instead of trailing @ 8' wire which was O.K, but SWR bounces
while moving, I wrapped the wire round a 1/2" dia rod, then
removed it. I then stretched the windings into a @ a 2' long coil,
that just dangles by my side.
I still can get a 1/2 bars SWR...
But it seems less sensitive to movement. YMMV.

well, sometimes it makes a perfect marketing concept to release a rig
that does not totally fulfills all the wishes (but is striking
enough to become a "must have"). This enables the engineers to work
on a "Mark II" ("now with US WX capability!") and the sales guys can
sell the newly developed radio to us who are originally happy users
of
the first release ... but still would like to have all the new
features ... and hundreds of used rigs are on the second hand market
again.

I like the idea of a downconverter as put forth by Dave and Pres.

Down to

10m FM sounds workable. Maybe W4RT Electronics could make a teeny

little

wart for the back of the '817.

I think the idea of using a separate HT or WX receiver defeats the

purpose

of getting it all inside one radio. Listening to FM broadcast

doesn't

defeat that, however.

Also, it is correct as someone mentioned that airports have local WX
broadcasts for pilots. For example, here at Cincinnati, the

international

airport has our friend, the computer voice, reading reports

continuously.

For arrival flights, the freq is 134.375. For departures, the freq

is

135.300.

Hi Rich!

Could someone please post the Radio Shack part number for the SWL
antenna used as a counterpoise? I've searched the archives and see
lots of references but can't find the original post with the PN.

According to www.radioshack.com, the part number is
278-1374. It is a 23-foot wire on a reel, with a clip that
goes over a telescoping whip. Retail price is US$ 8.95 and
available in stores or through the web site.

For mine, I cut off the clip that was on there and replaced
it with an alligator clip so it could go on my 817's grounding
post. Still need to test it out, which I will do this
weekend at home or around AZ since my car got smashed in a
hit-and-run and I can't take my loaner car to Mexico :( which
I had planned before the wreck last week.

Also, anyone know a source for a one piece "PL-259-elbow-BNC"
connector, or do I need to put 2 connectors together?

FWIW I haven't seen any.

I will echo Demetre Julian - we're not trying to drive you off - and
I suppose your comment " Due to the intemperate diatribe directed at
me by another member of this list" was directed to me - if so I
apologize if you took it as being intemperate.

But you keep insisting on things being one way when the laws of
physics have time and time and time again proven them to different.
You keep asking for help in trying to solve a problem that appears by
conventional theory, unsolveable. Also in some ways, not in need of a
solution - you might be perceiving a problem that doesn't exist.

A lot of people have offered you a lot of good help and tried to
point you in the direction to where you can help yourself more.
Eventually, people tend to get weary of pointing their finger in the
same direction.

I never studied Physics in school. I had to finish 6 months after the
rest of my class due to a run in with an instructor of a required
course. I never went to college. I could have if hadn't I been lazy
and bored by school. (I used to read books in primary school upside
down because it was more of a challange - helped in later in business
when sitting accross the desk from a customer or sales rep)

But I was curious about things wireless, and I read - a lot -
practically everything I could ever get my hands on about
antennas..... and a good amount of it from antenna companies is BUNK.

When I first started reading Moxon's book, after about 2 chapters, I
had such a headache, you wouldn't beleive!!! I didn't get a lot of it
at first, or at the second reading.... but I kept at it, and
experimented - a lot of them were failures, but others were
fantastic.

I was able to work all states and about 30 or more countries with a
12' dipole made from mobile whips that was 3' off my second story
balcony of a 4 story building of wiremesh and concrete running 50
watts. That was about my 10th attempt for a good working antenna at
that QTH.

So keep at it - maybe you will find the secret - here is a hint:
Moxon talks about radials for a vertical that are shortened with
loading coils working better than full length ones.... haven't had
the time to try it, but that may be the holy grail you seek - try
using your ATX as the "counterpoise" for the MP1 - see what that
does.... I am anxious to find out - and make the lower mast of the
MP1 about 3' - that should yield between 3 - 6 db better signal. And
maybe mount it on a camera tripod so it is higher and the "radial" is
less coupled to the earth - yes - a L-pole - I think it is your best
chance.

Hi Julian,

No need to be so radical man. I think everyone is trying to help
here, not to send members of the group away. After all these Groups
are for this reason, where we can all tell our opinion and help

each

other. Nobody here is expected to be a rocket scientist and I do

not

anyone of us here is.

On the other hand perhaps you could continue this discussion to a
more specialized group such as the HFpack. If you are not already a
member of it, I think it would be a good idea joining it.

As for a QSO with me Julian I am visiting the UK on 20 July and

will

stay there for 2 weeks. Please e-mail me privately if you like to
sv1uy@y... telling me if you are going to be there.

Also I will be QRV this Sunday at 04.00z on 18,157 KHZ and at

08.00z

on 28,337 KHZ and at 08.15z on 21,437 KHZ on my Sunday trek at Mt.
Ymittos talking to Keith G4MSF and Terry G0EHX. You are welcome to
call me. Feel free to break the QSO.

For anyone interested in an amp for your 817 check out
communication-concepts.com & rfparts.com. CCI has kits & RF Parts has a
circutboard, instruction book & the parts (not kitted though) for
building an amp suitable for use with the 817. They are both reputable
companies.

Hello All,

This maybe of interest to you.
Well I've had my FT817(ON160431) since January, Started using in
February.
Due to work & personal commitments I've only posted a few things.
So I thought it about time to share some information & experiences.
Some good(for me), some bad(for me).

1. Power Output.
Like everybody else(I think), I wanted to test the power output on
all bands.
I found it to be approx @ 5.0 +/- .1W across ALL bands, this was in
February.

In early April, while testing my PSK setup, I noticed the output
power to be low.
I'd been running 5 watts approximately 5 mins on 10.150Mhz into a 50
Ohm load.
I checked all voltages, connections, cables and connectors, all
seemed O.K
I decided to switch off, Try a full reset and re-tested. Results the
same.
I quickly checked all the other bands, the following is what I found:

Freq Hi L3 L2 L1
1.925 2.60 2.30 1.10 0.50
3.925 2.60 2.30 1.10 0.50
7.250 2.50 2.30 1.10 0.50
10.125 2.50 2.30 1.10 0.50
14.250 4.70 2.30 1.10 0.50
18.125 4.70 2.30 1.10 0.50
21.275 4.60 2.30 1.10 0.50
24.950 4.60 2.30 1.10 0.50
28.425 4.60 2.30 1.10 0.50
50.200 2.65 2.20 1.00 0.40
144.20 3.87 2.28 0.87 0.50
432.20 4.37 2.07 0.84 0.29

I thought it might be heat related, So I switched off the FT817 for
about 1hr.
I then re-tested,, Voila, The power output was @ 5.0 W across the
bands.
I then put it on TX for appox 5 mins, and re-checked the power output.
Well sure enough the power output had dropped again like the above.
BTW,, The equipment used is of Lab Standard Hewlett Packard equipment.

So power output dropped on certain bands by @ 40%, This was not right.
So off the unit went to Yaesu/Vertex/Standard, With all the above
details.

Well 3 weeks later, back it came, I ran through all the above same
tests.
Bad news, :-( It still had the same problem, power output vs
frequency.
So I called Yaesu and spoke to the Service Manager.
After lots of discussion regarding duty cycle he agreed to
investigate again.

Well after another 2 weeks, Back it came, I ran through the same
tests.
Good News, After 5 mins of FM TX the power remains @ 5.0 W all bands.
I used FM(for expediency), it will give a 100% carrier just like PSK.
The problem was related to the ALC circuit, according to the Yaesu
Tech.

2. Spurious "In Band" signals, some of the "louder" examples I found:
7.245Mhz, 3.895Mhz, 28.873Hhz, 50.242Mhz, 144.215Mhz.
The Radio was connected/terminated into a dummy load.

Well these have been reduced by approx 25-50%.(subjective)
Service report(first trip to Yaesu) indicated that "chip capacitors
added".

Finally,, Some good stuff(for me).
Got all my gear for Voice/PSK together in a Laptop Case.
I have the CUP36 PSU, HB PSK I/F into the data connector.
I'm more of a, Go some where, Setup, Operate, Packup, type of
operator.

At home I mainly operate the FT817 5W on 10M into a HB dipole at 25'
feet.
I've had some very good(I think so) contacts, with some QSL cards
already.
some examples(all on SSB):
3D2AG, 9A1CCY, A35NB, BV7ID, BY4CL, CO2KK, FO/DL1AWI, KH0/JR3TVA,
P29CC, PY2GD, S58N, T32RD, T77C, UA0FO, V31DY, V73E, VP5AZ, VP9KD,
YB0LBK, YV5DEH, ZK1JD, + quite a few VK's, ZL's, JA's, and 29 States.

Something(I personally find) that really helps on QRP contacts:
- REALLY, and I mean REALLY "EMPHASISE" the /QRP after your call..
Most of the above contacts said either, "QRP Only" or station
with "QRP".

Portable dipole/whip antennas for /PM...
I've briefly played with some modified large 6' TV "Rabbit Ears" for
10M.
One thing I did try with my 10M Maldol whip, and the results are
interesting..
Instead of trailing @ 8' wire which was O.K, but SWR bounces while
moving,
I wrapped the wire round a 1/2" dia rod, then removed it.
I then stretched the windings into a @ a 2' long coil, that just
dangles by my side.
I still can get a 1/2 bars SWR... But it seems less sensitive to
movement. YMMV.

Well that's it from me for now..

Oh by the way,, What about the FT817 itself,(excluding the power
problem)
A fantastic little compact and versatile radio, with lots of
opportunities.
The performance and operation is what I expected from a radio in this
class.
I'm going to keep it, and use it. Hopefully with no more problems or
failures.

Yes, Niggles & quirks.. But like always .. Caveat Emptor.

Once it's out of warranty, I plan to:
- Put a mini BNC on the rear panel, instead of the front panel. If it
will fit.
- Add a ADSP unit in the waste of space(IMHO**) battery compartment.

Best Regards
David - KG6CIQ - Northern California

** If I go out for the day, The internal batteries don't last a full
day.
So I plug in an external 12V pack , may as well use that empty space.
I have an AMCOMM ADSP unit, that I plan to take the board out of.

It is still available along with a "cheat sheet". I ordered one the
other day. I don't remember the price but it seems to me that both were
about $20 US post paid in the states. My 817 arrived yesterday & I'm
still reading the book.

Thanks to all for the interesting responses on receiving WX at 162

MHz on

the '817.

Here is something that just struck me:

1 - I beleive the only post on this matter are coming from US Hams -
there are members from other countries - do you guys not have marine
weather broadcast at 162.40 Mhz and up???

2 - I am in the marine radio business, and EVERY marine VHF that I
have seen since they became synthesized has had weather channels in
it - even the ones from Europe... and the usually have a function
that changes them from US/Canadian/International band plans - but
that only changes some of the channels from duplex to simplex. The US
market is large - but....

I just went to the Icom UK web site and the M1EuroV handheld shown
there has a WX button - same as the M1V I sell here.

I know there was "buzz" at Dayton about the '817 being engineered

for Japan,

but I don't think so. Why would they do that knowing the larger

global

market is out there? Doesn't strike me that engineering for just

one

country would make good business sense in today's world.

Oh - I don't doubt it - it can be VERY DIFFICULT to convince the
Japanese factories of anything. I am sure Chip and others at Yaesu
USA had to do a lot of work. Thank you Chip - I hope you get the
credit you deserve.

Back when Kenwood had the TH21 series handheld, KW Japan was
convinced that it was not necessary to put in a way to change the PL
tones and that it was impossible to do. I was at a meeting with
Kenwood USA personel, and Kenwood Japan, when the KW US guy asked me
for my TH41AT that he knew was in my coat pocket. He also knew that I
had installed a dip switch in it to select the tones. "Impossible,
eh?" he said as he put it down on the table in front of the
engineers. Note pads out - shortly, the TH21BT series appeared, with
a dip switch.

Icom Japan did not want to build a remote head version of their
marine SSB, which is a VERY large radio - something that can't fit
into a proper location on a lot of small boats (35' - 50' cruising
sailboats mainly). The US sales manager asked me if I could build one
out of the standard radio. I did, and a similar event occured. Now
that remote head radio is well over half their sales in the yacht
market.

Find a copy of the Japan version of CQ magazine - I haven't seen one
in a number of years, but I'll bet you'll be amazed how much stuff we
never see here.

ARS does NOT work after the mod.

You can still do MANUAL repeater offsets the normal way. Go to menu
row 4 (RPT REV TON), press A once for minus offset, twice for
positive. You should turn off the ARS setting (SETUP menu items 1 &
2). If you leave ARS on after the mod, use the RPT button to set the
offset, and then QSY, you lose the offset you just plugged in!

Turning ARS OFF after the mod allows the radio to retain the offset
if you QSY.

(this is much more confusing to read than it is in practice. sorry!)

I understand that after the TX mod auto offset is lost unless ARS

Well, think of it this way. When you do the TX-anywhere mod, you lose
country information. Therefore if ARS is on, it gives a simplex offset no
matter where you are. If you turn ARS OFF, then whatever repeater shift you
last selected is what you have. Pretty much like NO ARS at all.

Another way, a mod'd radio has no ARS and don't try to turn it on.

Does anyone remember 72-ohm twinlead? I used to love the stuff for
antennas, but haven't owned any for years. I asked for it all over

Dayton,

inside and outside, and the general answer was there is no market for it

at

this time so nobody stocks it these days.

vaguely, yes

Lots of folks seemed to remember it. It's thin, light, very flexible, easy
to use.

Does anybody know where I might buy some?

Have you tried "Press the Wireman"? ( not me <G> )

Didn't MFJ sell something like this several years ago? Seems it was
a box abt. 3x2x1 w/male bnc on one side & female on the other with an
on/off switch. I think I remember looking at this, then hearing
about the wideband rx mod for my IC-O2AT & deciding to try that
instead. I'm sure they discontinued it when those darned radio
manufacturers started building in wideband rx. ;)
