Tom and all,
It's likely that we can schedule AO-51 for a JOTA repeater during that
weekend.
If the bird can support it (power budget), we'll support it!

These radios also aren't dual receive either. Once there is activity on
2m, 70cm gets muted and vice versa. I intend to use one as part of my
V/S portable setup next week for AO-51. I'll use the Wouxun for the
uplink and a old TH-79A for the downlink.

I have heard guys working the birds using the Wouxun. The only thing I
noticed was that the audio seemed a bit lower. Make sure it is in wide
deviation.
Just my two cents....

Here's a tentative schedule for Cori and me tomorrow (Wed, 22 Sept) as we
take the grid
hunters route from Thermopolis, WY, to Grand Teton NP. Emphasis is on
tentative, but with
several passes available to my QTH, including two HO68 passes, we should be
able to get to
five and maybe even six grids if we keep our stops to a minimum.
Sat / local AOS / Grid(s)
HO68 / 22/1707Z / DN53 & DN63
HO68 / 22/1855Z / DN52
AO27 / 22/1931Z / DN52
AO27 / 22/2110Z / DN62
AO51 / 22/2235Z / DN51 & DN61
On Thursday, we'll swing up along the western side of the state and hit DN41
and DN42
along the way. Our current destination will be at Grand Teton in DN43 where
we're
expecting to camp for three days.
For the 6M ops, I'm still CQing for several minutes on 50.125 MHz after each
pass, but I've heard nothing but noise. Even though I'm running the rig off
batteries on a short leash and with the car shut off, I'm also getting S8
noise. That's not unusual when I'm in or near a town, but following today's
DN54 / DN64 operation at Bald Mt. in north central Wyoming, there was
nothing around for miles, yet the S meter was sitting on 9. I'll keep trying
though.
73,
Jim, ND9M / VQ9JC

Hi folks,
So, we had a swap meet a couple of weekends ago, and I found a bargain I
couldn't refuse. Of course, now I need to decide what to do with it...
The Find was a 35 element 1296mHz antenna, well built and in excellent
condition. Linearly polarized, horizontal; supposed to be 23dBi gain.
Manufacturer, of course, is unknown. No markings, but it does not look
home-built. By the mounting hardware, it looks like it was part of some
sort of stacked array.
The problem is that I already have a 1296mHz antenna. Home-made, circularly
polarized, 18 turns Helix. Should be something like 17dBic, if the
calculations are correct.
In the shack, which is at the wrong end of 60' of 1/2" hardline and a total
of about 15' of RG-213 or something like it, I have my Yaesu 736R and its 10
watts of screaming RF power. No preamps.
Which antenna should I keep up on the rotor assembly?
Last weekend I put up the new antenna. I've made one AO-51 LU pass with the
new antenna, and I was not impressed. Several times I couldn't get into the
bird, presumably because of the crossed polarization. But when I did get
in, it was full quieting, even at low elevations. I don't recall having
this much trouble with the Helix. I think AO-51 is the only current
satellite on L-band, right?
For other uses, there's nothing terrestrial to aim at, repeaters-wise;
they're all hiding behind one or more hills, or went off the air years ago.
That leaves Weak Signal work (hence the horizontal mounting). I do have one
shot into the valley, to the North West, but probably slim pickings for
contacts. I haven't tried EME.
I'm leaning towards putting the Helix back up, and passing the new one on to
someone more able to use it. What are your thoughts?
Thanks,
Greg KO6TH

Greg,
I would keep the one that works the best.
I have been disappointed in the performance of long boom Yagi's for UHF.
Resistance loss in the elements often reduces the gain by several dB over
calculated gain. Also they are very narrow band, the helix is good for an
octave.
Art,
KC6UQH

Hi Greg et al
I have been partial with the helix for satellites.? I run 10W to a 16 turn
helix through 40 feet of LMR-400.? I rarely have an issue getting into
AO-51.? I believe AO -51 is our only L band bird, I try to "exercise" my
gear when the opportunity is there.? I experience very little fading with
the L band uplink, input to the satellite is quite solid down to fairly low
elevations.? The yagi would as you mentioned would better for? terrestial
1.2ghz stuff.

Hello all,
I have a rather unusual question: can anyone tell me what satellite
was visible over JM49MG around 20.20 UTC of 06 Jan 2009? I have in my
log a contact via VO-52, but I received a QSL for that same contact
via "AO-07 orbit 56249". I tried with my predict program but with
current keps it gives result not meaningful for 06 January 2009.
Thanks in advance

Hello Dieter.
Try this.
Click on ... NEW CONTACT.
Scroll to the bottom of the page.
Check the - REMEMBER ME- box.
You should now be able to edit your 'own' entries by clicking on the
spyglass at the left of the screen.
Despite repeated requests, N1DID (formerly W0EEC) never updated my editorial
privilages a couple of years ago so if that 'trick' doesn't work
Dieter I'm afraid I can't help.
I CC''d this to the Amsat-bb for the benefit of others since it seems to be
a reoccuring problem.

M2 makes a 35 element 1296 MHz yagi, on about a 6' boom.
individual elements are insulated "thru the boom" with keepers.
Folded dipole driven element.
I used 2 each stacked vertically for AO-40. Yes, they are pointy.

The Find was a 35 element 1296mHz antenna, well built and in excellent

Manufacturer, of course, is unknown. No markings, but it does not look
home-built. By the mounting hardware, it looks like it was part of some
sort of stacked array.

Hi Greg, KO6TH
It is probably a Tonna 35 element yagi.

I installed one of these a few months ago, in place of my 20-turn Wimo
helix. Both are nice antennas, but I'll give the edge to the M2 yagi
(more gain and it mounts balanced on the elevation boom). I have
mine with vertical polarity. Since AO-51 is linear on L-band, it
shouldn't matter--but putting that little antenna horizontal in line
with my metal boom didn't seem to make much sense....

Hi Greg, KO6TH
If your antenna is from Tonna it must be 3,07 meters long.
Tonna make two models one for DX and SAT and the other one for ATV
By the way the gain is 20 dB isotropic.
20635 35 ELEMENTI 1260/1300 MHz dx,sat 20 dB 3,07 meters long
20636 35 ELEMENTI 1250/1260 MHz ATV 20 dB 3,07 meters long

I use a Directive Systems 25 element loop yagi and it works great for AO-51
L band. http://www.directivesystems.com I'm feeding it with 10 watts via
35 feet of LMR400. Directive Systems antennas are very well built and less
expensive than some other popular brands.

Hi folks,
So, we had a swap meet a couple of weekends ago, and I found a bargain I
couldn't refuse. Of course, now I need to decide what to do with it...
The Find was a 35 element 1296mHz antenna, well built and in excellent
condition. Linearly polarized, horizontal; supposed to be 23dBi gain.
Manufacturer, of course, is unknown. No markings, but it does not look
home-built. By the mounting hardware, it looks like it was part of some
sort of stacked array.
The problem is that I already have a 1296mHz antenna. Home-made, circularly
polarized, 18 turns Helix. Should be something like 17dBic, if the
calculations are correct.
In the shack, which is at the wrong end of 60' of 1/2" hardline and a total
of about 15' of RG-213 or something like it, I have my Yaesu 736R and its 10
watts of screaming RF power. No preamps.
Which antenna should I keep up on the rotor assembly?
Last weekend I put up the new antenna. I've made one AO-51 LU pass with the
new antenna, and I was not impressed. Several times I couldn't get into the
bird, presumably because of the crossed polarization. But when I did get
in, it was full quieting, even at low elevations. I don't recall having
this much trouble with the Helix. I think AO-51 is the only current
satellite on L-band, right?
For other uses, there's nothing terrestrial to aim at, repeaters-wise;
they're all hiding behind one or more hills, or went off the air years ago.
That leaves Weak Signal work (hence the horizontal mounting). I do have one
shot into the valley, to the North West, but probably slim pickings for
contacts. I haven't tried EME.
I'm leaning towards putting the Helix back up, and passing the new one on to
someone more able to use it. What are your thoughts?
Thanks,
Greg KO6TH
