Keith:

I am sorry, but I couldn't agree less with your request to move this
to the NVIS group.

As you mentioned, it was this group that has generated the most
interesting disucssion on that topic. I can think of no better way
to kill that discussion than to move it over to there. I think that
the synergy found here in that discussion has more to do with the
greater number of members of this group than there is with the NVIS
group (about a 6 to 1 difference). As a result, there is a greater
pool of experience to draw from this group, many of whom couldn't be
bothered to subscribe to a separate group. However, if there was
something of NVIS that peeked their interest, or may have something
to add, that opportunity would be lost because that individual would
not be on the NVIS group. Indeed, there was some more discussion in
the HFpack group, attributable in my opinion, to the greater number
of members in that group than in the NVIS group.

I think that with all the other off topic discussions that have
occurred on this group with little or no adverse comment, I fail to
understand why this particular should be banished, when the
advantages of letting it stay here are so overwhelming.

Anyway, I hope all the people who have been nice enough to comment

about

this will join John and I in carrying on this conversation on the

NVIS

board.

Jason NF6E also mentioned the calender which I hadn't really

considered but

sounds like a great idea.

Bonnie, I hope it will be OK to mention upcoming tests on this

understand and will try to get everyone to move the general

NVIS to the NVIS forum.

Everyone, I hope you will all join me in continuing this

Welcome to the group. I think most of us have been surprised at the
capability of the 817 and really enjoy QRP.

Yes, welcome!

Some of use are familiar with QRP and although not surprized that "qrp
works!" we are surprized how good of a radio the 817 really is!

Hi all,

Very good idea to use the calendar for online activity/meetings.

Just having this radio for a few days, and I did not believe that 5
Watt of power was going to make DX possible.

To test the radio performance on HF, I made an dipool antenna of some
electricity wire. Not realy a good antenna, and it was situated in
the middle of high buildings.

Then we made a call for DX on 7Mhz and 14Mhz bands. Nothing happend.
Then I replied on a DX call form Yougoslavia, Belgrad. We where
successfull, and got a 7/5 report on the signal.

I was suprised enough to deside the FT-817 and realy interested in
QRP right now. So count me in on this list for some time.

Thanks, great site with allot of good antenna info.

Don, Radio Works manufactures a big line of current baluns. If you go to their Web Page at www.radioworks.com I'm sure you will find the answer. It's my understanding that a current balun does a better job of balancing the currents in the legs of a balanced antenna when fed with coax.

Group,

air meetings? Perhaps antenna tests or just to let the group know

I assume the same calendar can be seen by all members.

Just a thought.

I can think of one - a horizontal half-wave radiator located one-

You are correct in concept, Jim. However, due to ground losses, in
order to be more efficient than a dipole at quarterwave height,
(efficiency is critical for utilization of the FT-817's QRP power
level) the zenith-oriented stacked dipole array you mention for NVIS
needs to have its lowest reflector or phased dipole element at least a
quarterwave above ground. However, you can achieve similar NVIS
gain antenna results simply by feeding two dipoles with equal
feedlines, with both of them about a quarterwave high, and separated
by at least 5/8wave spacing. Or easier yet, simply use a fullwave
horizontal loop at about a quarterwave height!

May I suggest that the excellent "NVIS" group on yahoogroups has
unlimited on-topic bandwidth to continue this exciting discussion. In
fact there is such a discussion going on there at his time we could
join in on. I look forward to engaging discourse on that forum, and
encourage other ops to meet there for a continuation.

IMHO, the FT-817 forum should be left to discussions of
FT-817-specific topics. The only thing that relates this very
interesting but diverging topic to FT-817 now is that the original
spark of the thread was an experiment that utilized FT-817 rigs as
transceivers.

There are 2 different sized center pins, because one is 50 ohms, and
the other is 75 ohms.

The smaller diameter is 75 ohms. From the equation

Z = 138 log10 (D/d)

where

Z = characteristic impedance for air insulated line
D = inside diameter of outer conducter
d = outside diameter of inner conducter (in same units as D)

I can't get the rubber ducky to connect to the BNC elbow I successfully
put onto the front of the radio.

Then the elbow has a problem. If it is seated nicely on the radio the
previous comments about difficulty seating a BNC on the radio do not apply.
But you may want to do the mod anyway

Thanks

GO BILLS!

it works OK. If it does, then maybe we have some type of issue with

the 817 connector since I too have experienced some resistance to
twisting and locking on BNC's to the rig.

Has anyone else had problems like this?

Yes, the FT-817 front panel has a clearance problem with many BNC plugs.
They do not seat fully.

Do NOT force the plug on, you will strain the ears on the socket. Rather,
remove the front panel ( easier than it sounds ) and ream out the front
panel hole. Seethe FAQ link below.

There is a photo of a handle for the 817 in the files section, titled
swiss_universal_handle. It looks pretty good. Where do you buy one?
Any other experience with it?

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.


thanks

Why not set up a filter and put all the e-mails into a folder.

That way,

when you have a chance, you can see the e-mails.

No inbox clutter!

Another good option...and one I am using right now..is to read the
messages right off the e-group list. It's easy to follow the threads
that way. Jo K5HOY

Interesting, the birdie on 436.025 MHz is S9++ but only when I connect
the whip antenna. It's very weak without an antenna connected. Checked
with another radio, when I switch the FT-817 off the signal on 436.025
MHz disappears completely so it's definitvely generated by the FT-817.

David,

Does your FT-817 also show birdies on 70cm (e.g. 436.025, 438.100,
438.900 and others)? I've noticed those birdies with 4 different

FT-817

at the Hamvention but didn't get any comments or confirmation from

other

hams regarding this problem.

Which birdies on HF did you find? The one on 7.240 MHz is very

weak with

my rig.

David,

Hello Tom

I did not do an exhaustive search, I just reported the most obvious.
I found the following very loud ones:
3.895Mhz, 7.245Mhz, 28.873Hhz, 50.242Mhz, 144.215Mhz, 432.261

The Radio was connected/terminated into a dummy load.
After a trip to Yaesu they have been reduced by approx 25-50%.
(subjective), the service report indicated that
"chip capacitors added".??

Thanks David,

The birdies on 3.895, 7.245 and 28.873 are very weak on my FT-817. The
ones you mention on 6, 2 and 70cm don't appear with my rig. But I
notice birdies on 438.100, 438.900 etc. which are quite annoying. Will
check with Yaesu if those could be reduced.

Hi John,
They are unfiltered & require the addition of filters to keep

the FCC & your neighbors happy. I am thinking about 1 of these amps
myself. I guess CCI at least gives you schematics for the LPFs.

73, Fil W8FIL

Hi Fil,

For those under the FCC rules, building the CCI amp (or the like),
even with the addition of filters, etc., violates Rule 97.315 -- you
can not buiild an external RF amp from a kit if the input is < 50 W
for full-rated output. The definition of "kit" as used by the FCC is
remarkably broad. I note that under the rules, it is OK for the kit
to be sold to you, you just can not build it. In contrast, if you
find a suitable amp that you can use directly that is already build
(kit or otherwise) or you can mod the amp to meet the FCC emission
regulations, it is OK for you to buy, own and operate it. However, it
is likely illegal for the person to sell it (exceptions are ham
dealers, ham-to-ham, ...) to you are anyone else. This is why THP
does not sell their amps in the US.

Roll your own design and build that legally (and maybe have a lot of
fun too).
