Has anyone heard the AO-10 beacon?
?
The sat is in full sunlight until July 24.
?
Is the beacon?signal a very slow QSB as was the downlink?
?

I was watching it too and i heard someone saying HOLD HOLD HOLD fsc is empty
(or something like that)
They said they know the cause but it is another "abbreviated" word something
who was or became empty?
Better luck next time.

Hi:
I will be attending the Great South Bay Amateur Radio Club's Hamfest
tomorrow, May 9th, 2009. The Hamfest will be held at Fireman's Memorial
Park, Lindenhurst, LI, if anyone is near the area.
I'll have an AMSAT table at the Hamfest and will be conducting a Satellite
demonstration for the AO-51,14:03 pass, it is a shallow one for us, I hope I
can hear you!
More information about the Hamfest is available at:

Hello to All,
Looking for suggestions for feed lines to my preamps, could I use RG213-U ?
I am thinking this should be ok as both lines will be only about 10ft in
length.
>From the preamps, I am using hard line.
I also have a UEK3000 receive converter for 2.4 , for feedline, could I get
away with RG6, same cable used for sat TV.
the run will about 80 ft....
Getting setup for future HEO.s
Any suggestion greatly appreciated and many thanks in advance.
Norman

Hi Norman-Back in the days of A0-40 (sobsob) I used (still do) a 3731AA
downconverter with a three foot off center dish (primestar).? I ran about 50
feet of RG6 and I found at times I still needed additional attenuation.? I
applaud you getting ready for the next HEO!? If we all did that it might apply
some pressure "somewhere".

Norman,
>From a loss standpoint, almost anything will be fine over the 10' length you
mentioned. The real issue is the quality of shielding, and the placement of
the leads. You will be operating in the near field of the antennas, and you
want to minimize RX pickup from the TX antennas before you get to the
preamps. RG-213 is a single shield coax, while RG-214, Bury-Flex, and
RG-9913F have double shielding. While the double shielding is better,
especially if the cables run close and parallel to each other, many people
do fine with RG-213. Note that the generic versions may have significantly
poorer shielding.
The UEK-3000 has 30db gain, and an 80' run with the 2 meter IF output should
not be a problem. Back in Ye Olde AO-40 Days, I had a 70' run of RG-8 down
to the shack. It was there, I was in a hurry, and it worked. (If you have
one with the 70 cm IF, the answer is less certain.) Be aware that RG-6 is
75 ohm rather than 50 ohm cable, the big brother of RG-59, so the SWR on the
line will be a bit higher. However, that should not be a problem.
Glad to hear someone else is keeping the faith on HEO.

Norman,
By your questions I guess you have heard that coax loss between
antenna and input of preamps degrades noise figure (which is why we
put preamps at the antenna in the first place). You do not mention
frequencies for the RG-213 but I am guessing you mean 145 and 435 for
satellite. Ten foot probably will not matter too much on those
frequencies though the higher the frequency the more coax loss gets
(and coax loss adds to the noise figure directly; e.g. 1-dB loss add
1 dB noise figure to the noise figure of the preamp - not good if the
preamp is < 0.5 dB NF). MY best advice then, is to use the lease
length of coax in front of the preamp. Compare how it hears with the
coax and without the coax and decide for yourself.
For 2401 MHz the situation is totally different. 80-feet of RG-6
will kill the low-noise performance of the UEK3000. Install the UEK
at the antenna with no coax or as short as possible a jumper
cable. If you meant to use RG-6 from the output of the UEK that is
quite OK. I use a MKU-232A2 + Drake downconverter on 2401 and run
over 100-foot of RG-6 from the Drake to my FT-847. But the MKU
preamp is directly connected to my 6-turn helix feed for my 85cm dish.
I am considering the purchase of a 10-dBi patch antenna to use on
2401 Leo-sats as it will be easier to point and should not need as
much antenna gain. This will be coupled with a 2400 DEMI preamp and
my second Drake converter.
