Well then, if the goal is to communicate -- and I'm _really_ not
trying to revive the usual code v. no code war here -- use CW. CW is
one of our tools, and this is what it's best suited for.

Anyone game for a FT817 Users net on the air?...for tests, and such?

There you go again Pres, being both right and wrong at the same
time. :-)

Your right in that I should have said WWV. However, WWVB is alive
and well, and is the 60 kHz station that is still in business but
lacking one tower, but soon to have it back and full power again.

WWVL???

Thanks for jogging my memory too.

I did a quick WWVB (10 MHz) test with the MP-1 and the B&W AP-10A

It's a tiny nit to pick, but you mean WWV at 5, 10, 15 and maybe

20MHz, and

WWVH in Hawaii on similar frequencies.

WWVL is the VLF emitter at 60KHz

WWVB is defunct

Right frequency, wrong call. WWVB is going strong (or, not as strong
as normal) on 60 kHz, WWVL was on 20 kHz but went silent in July 1972
according to the WWVB history page....



From there you can get to the other pages for WWV and WWVH, and
even to the other time services - including a way to update your
computer's clock over the Internet, either with a free program
for Windows systems or by configuring your OS to do it (newer
Macs with OS >= 8.5, most Unix/Linux systems, etc.).

WWVB seems to be working OK, since I have a couple of clocks at home
that use WWVB to adjust the time - and those clocks look just as
accurate as my GPS receiver or listening to WWV/WWVH. Maybe not
accurate enough to guide a cruise missile :) but certainly OK for
logging or simply seeing what time it is.

Back to work.....

Joe,

Many thanks for the step by step instructions. As a totally naive satellite
wannabe, it is a big help. Could you supply the URL for the G6LVB website?

But you can get 5W out using the existing 9.6V pack if you want to.
The problem is charge capacity (which is why the 817 defaults to 2.5W
when running on batteries) not voltage.

Julian, G4ILO

I worked my first totally portable satellite ops last night with my
FT-817. I worked several stations on A0-27 and copied CW from F0-20.
I heard packet replies from the ISS but didn't have my tnc connected.
Yes you can work most of the satellites with the FT-817 but you have
to be patient. Best of all, you do not need to program any memories.
Here is my stations configuration:
1)FT-817
2)Home made antenna similar to the Arrow Beam.
3)CT-67 Interface
4)HP-100LX palmtop (any pc that will run DOS will do).
5)InstantTrack software from AMSAT. This will cost you $25/$30
depending on your membership status. This is a great piece of
software and the purchase price helps AMSAT.
6)The latest KEPS (from AMSAT or ARRL).
7)The modified version of InstantTune from the G6LVB web site (Thanks
Howard).

First: Read the manuals, install the software, learn how it works,
succesfully update the KEPS. Get it working without the radio.

Second:Install the modified InstantTune and configure it. You may
need various RS-232 adaptors and a null modem. Get it working with
your radio on the bench. Don't try communicating yet. You may find
the sound of the radio being tuned somewhat annoying but the nature
of the FT-817 means you'll have to live with it. In addition, do not
try to configure the FT-817 with the function key while the tracking
software is in control. You will get very frustrated. Disable the
tracking control if you want to configure the FT-817.

Third: Spend time listening and tracking satellites. When you are
successful>

Fourth: Make contact, have fun.

Fifth: Listen for me on Field Day, QRP Satellite from EM28lq

Sixth: Support AMSAT.

Greetings All:

Recently, as a result of other discussions concerning using fishing

cam across this web page from Giovannini Antennas on a neat (at

least

I think so) portable mast, strong enough to support a small beam.
See the following link:



I queried via e-mail shipping costs to Canada. Needless to say, I
just about had a coronary when the response was $US160 via UPS and
that package is too big for the mail and can't be shipped by

I found a German retailer, at www.wimo.com who has the same thing,
more specifically at:



After three e-mails, I have given up because whenever I ask for a
quote, he goes off on some tangent and never answers the question.

I

can only assume that his failure to provide a shipping quote is a
strong message that he just can't be bothered.

Are there any other options that I have to get this masting to

Canda,

or am I stuck with UPS. (Actually, I am not stuck, because I will
not deal with UPS because they add a brokerage fee to anything they
ship into Canada. Maybe $US160 isn't outrageous for a courrier
company, but I don't need this tomorrow - I can wait.)

In advance, thanks for any advice.

Wow! I guess I opened a can of worms with my question. :-))

Perhaps I should have made clearer my intent.

817 data says output pwr is 2.5 w with internal 9.6v batt.
it also says output is 5w with ext 12v.

You CAN have 5w with 9.6v... for a shorter time. Set the power to where the
icon FLASHES... that's the higher-than-high power setting of 5w on internal
batteries

Thanks

After building a Z11 tuner and beeing very pleased with it, I looked
forward for a smaller one, for portable use.

Everybody knows, that the Z11 is a optimal supplement for the FT-817,
so why not using a similar tuning cuircuit as a manual tuner.

I did built it from scratch into a very small box (even smaller than
my homebrew ZM-2) and fasten it with a rubber band together with my
ultimate cw accessorie box (external keyer and dc distribution.
Tuning is acomplished first by maximum receiver noice and after
keying the TX to lowest SWR on the bargraph. It?s done really
quick and you are able to record the switch and condenser settings
for further tune up.

This tuner was able to perfectly tune a 20m random wire (from the
window of my shack down to the garden) on all band?s from 160m to
10m. I got even a match on 50 MHz! You see, 20m is a good length
always!

Look to the file section at "FT-817 Accessories"
for further information.

Your use of Yahoo! Groups is subject to

I am not sure if it's mute, but it is moot, since the internal
charger is supplied by 13.8 VDC from the back connector and is
basically a constant current source...it would not be able to charge
an internal 12 to 13.8 VDC battery..

Why not just change the power level? You do this via the menu setup
and a,b,c keys. You can do that and get 5 watts with the internal
battery...even the alkalines...but NiMH are much better in terms of
maintaining voltage with the high current draw.

I have to agree. I tried a pair of 20 meter Maldol whips configured as a
dipole and fed with coax. It worked but then I tried a 15 meter wire dipole
fed with ladder line to a Z11 autotuner. The tuner has no problem loading
this on all bands from 40-10 and even at very low heights (6 - 8 ft) it
works much better than the loaded whips. It easily rolls up for carrying
around. Cost of two Maldol whips, $90.00. cost of the dipole, pennies!
