Subject: [FT817] More Balun Questions


I have yet another Balun question.

I recently purchased the balun that is the companion to the LDG Z-11 tuner.

It did not come with very good instructions and I am looking for some ideas as to how to wire up a wire antenna to it.

Any help would be greatly appreciated.

Thanks

Good report, Barry, tnx.

Two questions for the group. I went to eHam and read the

If you were prioritizing (echhh! <g>) purchases between the
SSB filter and the ClearSpeech unit, do you have any feeling
that one would be a better value than the other?

Also, has anyone tried the version that is built into the
external speaker? Looks like it's designed for use in a
vehicle but could do duty in the shack as well?

I just bought a FT-817 at HAMCOM in Dallas a week ago. Works like a

charm. Since I am an Army MARS member, I tried the extended frequency
mod.

I did the solder blobs on pads 1-4, and cleared the solder blob on

the 5th pad. No extended TX on HF/2M/440.

Have done the power + V/M + F reset many times with no effect.

Also, when I do the power + V/M + F reset the display comes up

160m - L
1.800.00

Nothing else shows. Nothing works until you hit one of the other

function buttons, then the display reverts back to normal.

Although I haven't looked at it with a magnafying glass, I am pretty

sure none of the pads are shorted to each other.

My serial number starts with1E29xxxx

I am baffled. Has Yaesu changed the firmware/hardware?

Hello,

I agree with Bob, Just read what they say.(carefully)

I'm sure it will work a lot better than just sticking a single
50" whip in the back of the FT817 with no tuning arangement,
On it's non-resonant frequencies that is.

Subject: Re: Balun

Just a little info on your question...

A 1:1 current balun is equivalent to a transmission line running
through a choke core - by isolating one side from the other to
non-differential conditions, it prevents rf from getting back down the
feedline once it's "released" from the transmission line at the
connection to the antenna. This helps to force equal currents to flow
in the antenna legs, as they have nowhere else to go (so to speak). A
sleeve-type balun (a few cores strung on the coax at the feedpoint)
will work identically.

A 1:1 Voltage balun is a 1:1 transformer, with one side (feed)
referenced to ground (the shield) and the other side floating (the
antenna). Either works fine, but the current type has the advantage
of limiting rf on the outside of your coax in the case of reflected
power.

Voltage baluns show up when someone is trying to create a ratio other
than a whole-number-squared (1:1, 4:1, 9:1) like, for instance, 6:1
as these cannot be created with the "transmission line through a core"
model. Thus they resort to the transformer model instead.


Regards... Robert

Can anyone enlighten me regarding the difference between a 1:1

balun

marked as a "Current Type" and another 1:1 marked only as a balun?

I am

going to use either one to couple unbalanced coax to a flat top

dipole.

Subject: Web site update - THP HL-50B infomation

Hi, everyone,

I began work this morning on an amplifier section for the Tokyo Hy-Power
reflector web site. It will have four pages, total, and the one that I

think

will be most interesting to y'all is the page with info on amps for use
with low power rigs. That page is about one third done, and I have to run
otherwise I'd get it done now. The main thing, especially for those on

the

FT-817 and HFPack groups, is that detailed specs and mod info for the

HL-50B

are already posted. The page, which is a work in progress and is not yet
linked from the other pages, can be seen at:



Comments, contributions of more info, and constructive criticism are

always

welcome. I hope this page can provide useful info to those considering an
HL-50B to go with their FT-817 or other QRP rigs.

73,
Caity

Hi Frank,,

You tell me.. But I think you are, Again read it carefully.

What's "your" point of reference for small.?
anything less than say 5 over 5 stacked beams.

Just because of a(maybe)unfortunate choice of names,
It do's not change the facts or their comparative statement.

All they are doing is comparing a standard 50" whip,
with their 50" whip with a built in tuning arrangement.

I'm pretty sure if they had named it the "ABC Antenna"
this thread would not exist.

"Small" is what *I've* got :-) At least as far as signal is concerned

I guess I was wondering why the discussion of "frame of reference"

I had a 160 meter slinky antenna as an inverted v. It worked very
well. A rope down the center was secured to the loops at short

Hi Gang,

I've seen / used small antennas before ( the HT-750 antennas for
starters and the the PW-1 now )and have come to a conclusion; they work
but not well!

Don't take this the wrong way... they do work, ( yes I've worked DX on a
40inch whip), but poorly due to the physical/electrical size of them as
compared to a regular HF antenna.

If there is no choice then of course use a shortened antenna, but most
of the time there is an option.

Any light weight end feed wire of lenght(without coax)or light weight
dipole (or V ) with coax/twinlead will outdo the small antenna easily (
and prob fit in a zip-lock bag).

comments welcome

Subject: Small, portable, light weight Hexbeam

Group,

I found a website that some of you are probably already aware of. This
company manufactures a portable 2 element beam made of wire and fiberglass
spreaders. I believe the weight was under 8 pounds, the gain was around
4-6db, and the turning radius less than 10 feet on 20M.

They also have a 5 band beam. I haven't purchased one of these yet, but

I've

read more than a few good reports on them. It seems they are comparable to

a

trapped 3 elem./3 band yagi in performance, but with a much smaller
footprint. The wire element lengths are full sized, and they're suppose to
quiet like a quad. They also sell collapsible masts for portable op.

If any of you have any experience with these I'd sure appreciate any
comments you might have.

Their website is

Hi Jo,

My first reaction is that you have "Split" enabled some how.
I assume you have something like 146.525 on the display, and
then when you press the PTT the 7.00 is appearing.?

I don't have my manual to hand. Look in the manual for operating
in split mode.
That is receiving on one frequency, and transmitting on another.

here's a tip discovered recently that me be of help to others. I was

playing around with an MFJ and Icom mic and the Ft-817. I noticed that when
I used an rf power any (35 watts) for two meters, and the MFJ mic I would
get rf feedback on the transmit audio. Really distorts the audio! The
Yaesu hand mic did not produce the same results, it worked perfectly.

I discovered that you can remove the coiled cord from the Yaesu stock hand

mic, (squeeze thru the boot at the bottom of the mic) and you end up with a
very well shielded cat 5 cable that can be connected to the MFJ or any mic
that requires an RJ-45 connector.

Subject: [FT817] New Antenna for the FT-817 and other QRP portables...

Press Release

June 15th, 2001
Montreal, Quebec


The Miracle Antenna Company is pleased to announce the release of

The

Miracle Whip for the FT-817.

The Miracle Whip is an all-band (1.8 to 450 mhz) 50-inch whip

antenna

with integrated tuner for transmitting and receiving that mounts
directly on the FT-817. It operates with a typical SWR of 2:1 or
better across this entire range, and may be operated without a

ground.

The Miracle Whip exhibits remarkable DX performance for a 50-inch
whip on the FT-817 (and should do just as well on any similar rig).

We

have consistently worked DX stations on SSB under good conditions in

our tests; we are confident there is no other antenna its size on

the

market that will perform as well or better. In fact we believe

there

is no other antenna like it on the market, period.

The Miracle Whip uses a uniquely designed C-VAT - a Continuously
Variable Autotransformer - to match the whip to the 50-ohm output

of

the radio. Tune-up may be accomplished simply by peaking the

one-knob

tuning dial for maximim signal strength on receive - the antenna is
then tuned for transmitting.

The July issue of QST magazine will contain an article by our chief
designer, Robert Victor VA2 ERY, on building a Miracle Whip

yourself.

We have engineered an electrically similar, but mechanically
different, high-quality precision-mechanism version of this antenna
built to commercial standards to offer to our clients.

The Miracle Whip will retail for $109.95, but may be ordered for a
limited time via our website for $79.95. Groups members are invited

to

visit www.miracleantenna.com to review more information on the

Miracle

Whip and our other fine products.

Readers may submit questions regarding The Miracle Whip to
lebloke@....

Thank you!

I agree. For my home-made mag-mount antennas, if they don't blow off
the car, I can make them larger. So far, I am up to a Bug-Catcher made
out of various masts and coils. The longer the better.

Mark,

The Hexbeam is excellent and real. In short, it was the only antenna
to hold up for Chuck at Bouvet Island. It is a bit pricey, but worth
it. I have the 5-band one ready to put up soon. Friends that have
it simply are very pleased with the Hexbeam.

Group,

I found a website that some of you are probably already aware of.

This

company manufactures a portable 2 element beam made of wire and

fiberglass

spreaders. I believe the weight was under 8 pounds, the gain was

around

4-6db, and the turning radius less than 10 feet on 20M.

They also have a 5 band beam. I haven't purchased one of these yet,

but I've

read more than a few good reports on them. It seems they are

comparable to a

trapped 3 elem./3 band yagi in performance, but with a much smaller
footprint. The wire element lengths are full sized, and they're

suppose to

quiet like a quad. They also sell collapsible masts for portable op.

If any of you have any experience with these I'd sure appreciate any
comments you might have.

Their website is

Hi Gang,

I've seen / used small antennas before ( the HT-750 antennas for
starters and the the PW-1 now )and have come to a conclusion; they

work

but not well!

Don't take this the wrong way... they do work, ( yes I've worked DX

on a

40inch whip), but poorly due to the physical/electrical size of

them as

compared to a regular HF antenna.

If there is no choice then of course use a shortened antenna, but

most

of the time there is an option.

Any light weight end feed wire of lenght(without coax)or light

weight

dipole (or V ) with coax/twinlead will outdo the small antenna

easily (

and prob fit in a zip-lock bag).

comments welcome

best

Subject: More Balun Questions

I have yet another Balun question.

I recently purchased the balun that is the companion to the LDG Z-11

tuner.

It did not come with very good instructions and I am looking for some

ideas as to how to wire up a wire antenna to it.

Any help would be greatly appreciated.

Thanks

Subject: Re: Need transmitting help!

My first reaction is that you have "Split" enabled some how.
I assume you have something like 146.525 on the display, and
then when you press the PTT the 7.00 is appearing.?

I don't have my manual to hand.

I couldn't figure it out even with the manual ;-) I have been just
playing around with this thing so decided to just do a HOME + POWER on
and start all over. It seems to be working OK on 2 meters now. Jo

Any light weight end feed wire of lenght(without coax)or light

weight

dipole (or V ) with coax/twinlead will outdo the small antenna

easily (

and prob fit in a zip-lock bag).

The problem is an available supporting structure of a dipole/inverted-
V OR an end fed wire (which also needs a counterpoise of some sort
[and that will re-start a whole different subject all over
again]) ;) isn't always available! That is the point that keeps
getting missed. Or maybe the real-estate isn't available - YES a
dipole will work better - but frequently it is not practical or
possible to put one up!

I think it was here or the HF Pack group that the "Black Widow"
fishing poles came up last week. I have purchased 2 of the 20'
versions (about $45 total delivered from www.cabelas.com - ordered
Saturday, had them Tuesday ).

I have fashioned a mounting horn out of 1 1/2" PVC pipe to hold them
in a V (upright, not inverted) and plan to try my design using wire
wrap wire for my trials - if it works, I will used 26 gauge flex-
weave from Radio Works.

What I have modeled using NEC4WIN is a triangle loop fed at the
BOTTOM with a gap opposite the feed point. Each leg is about 19.5 '
up the V and then 14 ' towards the opposite side accross the top with
an insulator in the middle - probably use a rubber band for lite
weight and tension.

With it mounted at 30" - inches not feet - picnic table-top heigth -
the modeling shows some nuls off the side, but better performance
than a full size 1/2 wave resonant dipole @ 20' on 10/15/20/40 and @
40' for 80. Lower angle of radiation and more of it at the horizon!
In fact, on most bands, the angle gets lower when ground mounted.

It also looks like it has some pretty good high angle stuff too on
the lower bands for NVIS - with the zeinth pattern sort of a 3 leaf
clover shape - now if I can get the Z-11 to match it on those bands -
first try will be with the tuner right near the feed point and NO
balun - we'll see - think I'll go pick up a 4:1 balun just in case.

Could/will use my SG231 with my Icom stuff for higher power - sure
that will match it.

So here is a self-supporting antenna that looks like it will perform
well, cover a broad range bands, is fairly light weight (I'll weigh
it later), will be easy to mount, doesn't require a
counterpoise/groundplane and is easy to build and will work with an
automatic tuner - so once it is up, no adjustments are necessary -
this sounds too good to be true! Maybe we should call it the Miracle
Whip-beater antenna!!!

Will keep all posted - but plan on having it working for June 30 HF
Pack schedules. See you on the air.

Subject: Green Wire Mod -- Do you have 3 or 5 wires?

I just did the Green Wire mod on my FT-817 this morning, and I found
that popping out the green wire with a pin was easier than I had
expected.
Before doing it, I checked the information in the FAQ, and it says
there are three wires, one green, one black and one red.
Interestingly enough, I have FIVE wires: one green, two black and two
red. I presume the pos and neg lines are doubled (parallel) to reduce
the voltage drop and current loss.
My white plastic connector is a five pin. Could it be I have a
newer or different version of the rig here in Australia? Or does
everybody actually have five wires (but three shared connections)?

Subject: MOD problems

I just bought a FT-817 at HAMCOM in Dallas a week ago. Works like a

charm. Since I am an Army MARS member, I tried the extended frequency mod.

I did the solder blobs on pads 1-4, and cleared the solder blob on the 5th

pad. No extended TX on HF/2M/440.

Have done the power + V/M + F reset many times with no effect.

Also, when I do the power + V/M + F reset the display comes up

160m - L
1.800.00

Nothing else shows. Nothing works until you hit one of the other function

buttons, then the display reverts back to normal.

Although I haven't looked at it with a magnafying glass, I am pretty sure

none of the pads are shorted to each other.

My serial number starts with1E29xxxx

I am baffled. Has Yaesu changed the firmware/hardware?

when the whole thing was so obviously a joke at the expense of
gullibility, wishful thinking, and overly-high expectations.

Very well done for a joke.!!!
I can not vouch for the availability or legitimacy of the product.

Guys, guys. I don't believe it is a joke. Go read the info at the
pages. They have photos of the gadget. It's much too much trouble and
work and expense to be a joke.
If they really have come up with a variable transformer that does
tune all that range, then it's a fan-bloody-tastic breakthrough. Are
we all too clever or cynical? Are you all going to tell me I'm too
gullible or stupid? Laws of physics, etc...

We're not quite yet set up to "take the plastic" but how's this...
We'll accept equivalent payment in aussie dollars (exchanging is no

We'll ship to you airmail for 10.00 additional (our normal charge

Comes to 89.95 - as I read the exchange rates, ($1 AUS = .52 US)
that's about $172.00 AUS. Please let me know if I'm way off on these

Drop me an email with your full address, tell me you're putting

Hows that..?
Hope we get to send you one. Thanks for your interest and good

Subject: Re: More Balun Questions

I am looking for some ideas as to how to wire up a wire antenna

Brian, it should be pretty straightforward. You run a coax
patch from the last device between the transmitter and the
antenna (probably your Z-11) and attach the wire antenna to
the balun. If you are using 450 ohm ladder line, you can
solder banana plugs on and the spacing of the conductors is
such that you can plug them into the ends of the binding
posts. If you are using something else, you can either
solder banana plugs on and plug them into the jack ends of
the binding posts, or you can unscrew the outside part of
the binding posts and there should be a hole through which
you can insert a wire (one per binding post) and secure by
tightening the binding posts.

Hope this is clear; come back again if not.

Jo. I have just got to laugh WITH you. The first couple of weeks when
I was getting used to the little beastie, I had to do that reset
quite often. I'd get the FT817's settings all mucked up somehow and
couldn't figure what I'd done. The manual is far too obtuse.
Kind regards,
