Errrmmmm ... I connected it to the antenna, measure the SWR across the band in question and them based on the result I can decide
if I need to make the whip longer or shorter ... it's a great tool as it makes tuning a lot easier ...

Hi John !

The MFJ 259 is great for tuning the antenna without running down the
batteries,
but it is as big, if not bigger than the radio :)

The FT817 is a super little radio, really enjoyed the weekend, will be /P
again soon from a forest not too far from where I live ...

Cheers!

Hi All !

I really enjoyed the WPX CW contest too, didn't have a huge amount of time for operating,
but the FT817 was a real bundle of fun to use on CW contesting !

Will be out again in a couple of weekends time with the caravan and FT817, anyone fancy an FT817 sked ?

I saw Chip's comments on the success he had over the weekend with the
little rig. I can't top his record! But I did want to just mention
that I, too, enjoyed contesting last weekend with the '817.

Over a period of a little better than 10 hours, I made 60 DX (only)
contacts. All but 4 or 5 were in Europe and the remaining few were in
the Pacific (JA & VK) and South America. Three or four of the
contacts were on 10 meters or 15 meters. All the others were on 20
meters. All contacts were with a (15 ft high) 20 meter dipole and no
tuner.

I was using my new CW filter which UPS delivered only a couple of
hours before the contest began! It sure does help - especially when
coupled with the movable bandpass.

I made one contact at the end with the 1000mp just to confirm the
fact that it is easier with the "big rig". It is! But there's no
denying the special kind of fun that comes with doing it with the
little fellow.

I really appreciate how hard several of the guys worked in "breaking
their rhythm" to allow the multiple repeats it occasionally took to
make the contact. I never mentioned in any contact that the rig was
QRP. Thanks again guys!

Hi Julian !

I've had similar comments about the antenna I built at home for 160m.
I have a very small garden, hence now large wire antennas, so I constructed a 15m tall
top loaded vertical for 160m.

I had all the local G3/G4's tell me I'm wasting my time, "You'll never work anything with that" came the comments,
however winter just gone I was working South American, USA, and Far east stations that they couldn't even hear !

It just goes to show, it's worth trying anything, cos you never know, you may get it right !

The outbacker is an excellent antenna for the size, and so convienient to travel with as it
collapses into small manageable pieces.

They are quite expensive though, I think Nevada are selling them for 229.00 at the moment, Steve got his
at a special price when they had an offer on, 169.00 ... lucky sod !

We should arrange a sked for a chat on the 817's sometime ...


Cheers!

Hi Nick!

I have to say I am most impressed by the Outbacker Outreach, with 5w I could work
all the stations I could hear ...

I also take a full size G5RV and ATU with me, but not all camp grounds lend
themselves to stringing out a large wire antenna, this is where the outbacker comes
into it's own, small footprint and works a treat !

Cheers!

I was in Australia back about '94 and while in central Queensland saw a

variant of the Outbacker, mounted high on the front crash bars ('Roo

I have never used one but would not let the opportunity go by if
presented with a real deal...

Hi all !

The first time I saw the outbacker's performance was when Steve bought it over to my place with
his IC706MKIIG.

We setup the antenna on the tripod on the gravel in the back garden, run about 15m of coax back to the
shack and connected the 706, within minutes we were working USA on 20m ...

I think the problem is that many people buy them and then do nothing about a ground system for them,
like all short antennas, you got to do a fair bit of work on the ground / counterpoises to get any results.

The Tripod from AlphaDelta makes it a lot easier to get good results quickly but even it can be improved on !

Cheers!

Hi

However, you are using a decent antenna. I tried 6 today but the
rubber ducky thing Yaesu supplies is worse than useless, and won't
give a decent SWR even with a counterpoise. I didn't have any luck
using the ATX either.

Well I made a dipole out of 3 metres of thin wire, centre fed it with
a bit of 50 ohm coax (12 feet!) I had lying about, hung it at an angle
from an upstairs window into the back garden - the bottom was only 6
feet high - and I worked all over Europe on CW & SSB - I had a ball
both on Friday & Saturday!

I think the trouble with 6 is that as soon as
there is an opening, word quickly gets round and a lot of keen DX
types come on running a fair bit of power to beams. Trying to call
using 2.5w to a short whip in competition with those guys is a bit
like pissing in the wind.

I agree about the whip - but like I said above - an antenna doesn't
need to be exotic!

Try it!

Has anyone tried a telephone headset for the rig? They are small and
light.

And in the same vein, does anyone know where right-angle boots for
8-pin modular connectors can be obtained? I'd like to make an
adapater that lays alongside the radio.

I've used my old Heil BM-5 with the unit on VHF FM, and am told it
sounds fine. But even that's a bit large.

73, doug

It is a low voltage sense wire that inhibits the
charging circuit from working if the AA battery tray
is pluged in with any cells in it.

Yes, I find the B&W AP-10A works somewhat better than the MP-1.

Now you have me intrigued, Barry!
How did you mount your B&W AP-10A on the FT-817?

*** I didn't mount either antenna on the 817. Not my style. When I
am doing what I think you call PM, I go to a place a set up an
antenna, but not on the radio. I find it unpleasant to try working CW
while walking. :-)

Is there a new B&W FT-817 mount, or did you drill out the stock one?
*** Not that I know of. I see no reason at all why one could not
make a FT-817 mount for the AP-10A.

Is the AP-10A different from the earlier "window sill antenna" they
have had for a long time?

*** Yes. Long time is 40+ years!

I think the earlier one required using tools to move the frequency
band taps, and for dis-assembly didn't it?
*** Well sort of. You had to change coils in an inconvenient way in
the OLD version.

Did they change to 3/8-24 standard threads on the new one? That would
enable us to plug it into a regular mobile or MP-1 Superantenna FT-
817 mount.
*** No. The bolt in the coil bottom is a standard 1/4-20. It is a
trivial matter to make a transition part.

Is the new one an "air dux" coil?
*** Yes. The coil housing is PVC having an overall length of 7" as I
recall. The coil is 4" in length and 2" in diameter. Textbook
design.

How small does it pack up?
*** The bracket for window sill or table edge or ... is about 15"
long. The stainless steel whip is about 23" long when collapsed
(BTW, its diameter is about twice that of the MP-1 whip). It is a
bit more of a pain to pack, but is easily finds a home in my carry-on
suitcase fir airplane travel. No question that the MP-1 is the champ
of champs for packing small.

FWIW, I have frequently mounted the AP-10A on the edge of a table, a
2x4 in the clamp with a few bricks sitting on the exposed parts of
the 2x4, in hotel windows, etc.

For a 33' mast try the MFJ-1910.

Gerry,

Very interesting. I saw the picture with the car on his website. How do
you anchor this beast? Did you build a plate that you can drive your car
over and insert it into the plate? Do you guy it? Just wondering.

Thanks for this great link.

Hi,

I bought my mast @ Dayton... $99, and it is Great! The DK9SQ
mast:

I was on the beach in Wells, ME this weekend, running the 817 and
a vertical dipole... was a Blast!

colapsed, it is 3.8ft.

I bought a plastic housing unit at Home Depot for $5 and I was able to
get about 70 feet of #26 on it. I actually could have gotten more but it
foulde up some so I went back to 70 feet and had no more reel fouling
... works slick!

Check out New Jersey QRP Club's website for a great article on making
& using kites for antenna supports. It should be applicable to
balloons as well. The relevant point: use MUCH lower strength line
from your antenna connection point to the kite than you use from the
antenna down to the ground. If you lose control of the kite, the
line will break at the connection point, and the antenna will fall
straight down. Of course, you would ANCHOR the line at the ground in
order for this to work, so it would be impossible to drag your rig
off, anyway.

Howdy All,

I bought an MP-1 at Dayton and I would like to store the

Hi Jerry,

For travel operation the whip and 8 inch mast can all store
within the body of the MP-1 if you remove the slider from the
coil body and insert the 8 inch mas first. I also have a 3/8 inch
nut on my 8 inch mast and that end goes in first with the nut
at the far end. Next insert all the aluminum mast pieces one
by one with the bottom piece having the 3/8 stud on it last
and that end up. You can only insert the number of whip
sections that add up to about 54 inches. I forget how many
that is off hand. If you have extra's (most do) they will not
fit.

Sincerely,


/s/ Steve, N2CKH

Does anybody know where I can buy helium in a small spray can? A
couple of small baloons ought to hold up a decent length of wire for
an hour or two of operating. I thought about flying a kite (have been
told to do that before), but had a horrible mental image of me
chasing my 817 as a gust of wind drags it/me away...

Sam's Club ( a wholesale-type warehouse store ) or any party supply place
sells balloon kits with a 20lb-type can of helium and some balloons.

This is a fun radio and a fun list.
