Thanks everyone for all the replies ..
I am sure I should be able to find them now ..
Got some LMR 400 coax .. Currently using RG8/U ...
50 ft run .. Hoping for better receive on 440..
It came with N type connectors.
I tried to find LMR 450 and it seems hard to find ..
Thanks again all and see ya on the birds .. :)

Yes,
Quality and Radio Shack items are not #1, however, if you need something
ASAP--Find another place to walk into and find something amateur radio

Hi Enzo,
Yes the 1.2 Ghz uplink does work on the BBS. How many watts are at your
antenna and what is the antenna gain? I find that 30W at my 20+dB gain
antenna is not enough unless the view is clear of any trees.
I find the 1.2GHz uplink to be difficult on the BBS so keep trying!
Current logs show several users from around the world. JA, VK, OZ, WA
stations are some examples.
There is no other bird to test with.
73,
Mark N8MH

I am trying the bird on:

Does it work?
With the MSPE I can just receive numbers like:

What does it mean?
I am trying to request the DIR on 1268.700 MHz, but I do not get any
response.
I am asking because I would like to see if my system works.
Is there any other Bird that I can use the 1.2 GHz Band?
Thanks in advance.

I'd like to point out that the cables may look the same but?when tested you
may be surprised at the results.Having looked at a number of different cable
I have found a big difference in performance. After sweeping the cable over
HAM bands the SWR can?run from 1.5 up to over 6 to?one .Suggest if possible
be for installing terminate and test over band to be used. Make sure the
load on one end is 50 ohms over that band?as test results will only as good
as test equipment used.Jack WA1ZDV

Hi Enzo,
As Mark has pointed out, you need a fair ERP to get in to the mode L
receiver. I have about 2500 ERP, and can get in fairly reliably with no
trees in the way, but not as well as I did back in the KO-23 days. Because
of antenna placement (?) it sometimes makes a big difference whether the
satellite is approaching or leaving, both on packet and mode L voice.
Two things to check are your frequency and calibration, and your deviation.
Not all rigs, and especially transverters, are accurately calibrated at that
frequency. Mine are not, and I used a laboratory grade frequency counter to
get the correct values.
Also, there is a consensus that the actually uplink frequency is about 3 KHz
higher than published. I use 1268.703 MHz. The receiver is fairly wide,
but every bit helps.
Finally, make certain the 9600 baud deviation is good, preferably with a
good deviation meter.
Good luck,
Alan

Unfortunately, the quality of the vast majority of r.f. connectors sold at
Radio Shack has to improve considerably to even make a rating of "dismal"!
For example, I have run into PL-259 connectors with over 1 dB of loss PER
connector on 450 MHz.
Mouser ( http://www.mouser.com ) has various adapters as well as other
sources that have been given.

Hi Luc,
I am assuming you meant 7/8" Heliax.
45' of Heliax and a short LMR400 jumper will have around
0.6 dB of loss on 70cm so that just adds 0.6 dB to
the noise figure of your preamp (i.e. ~1.0 dB to ~1.6 db.)
With even a modest gain antenna, you probably will not be
able to notice any difference on a satellite downlink.
On 2 meters, even less difference.
73,
Tony AA2TX

OK, Luc. To make this decision you need to do the math. But you can
just try comparing performance by installing the preamps at the
antenna and at the shack and make your own evaluation. I'm guessing
that is not convenient as antennas are on a tower.
You mention running two coax lines "1/78". I do not know what that
is but it sounds like ridiculously small stuff like RG-174. Or did
you intend to say 7/8-inch? 7/8-inch Heliax is low loss (0.44
dB/100-ft and 0.83 dB/100-foot respectively) so that certainly helps
when installing a preamp at the shack. But without numbers it is all
hand waving and no decision is possible. How long is the
Heliax? Also, not familiar with "psp" relays. What is their
specification for insertion loss? If more than 0.2 dB they are not
very good. I use relays rated at 0.05 dB loss.
What is the NF and gain of the preamps? What is the NF of the radios
that will be fed? Get all that and coax loss figures and input them
into my spreadsheet program to find out what the overall NF will be.
http://www.kl7uw.com/emelink.xls
Add sky noise temp, Antenna noise temp, and radio bandwidth to
determine minimum signal power that produces a zero SNR.
Then you will have the figures to determine the effect.
My overall experience is you will not have the best receiving system
unless the preamps are at the antennas. You may be "satisfied" with
preamps in the shack if you never compare with having them at the
antenna. That is sort of saying driving a Ford Pinto is "just as
good" as driving a Ferrari. Both will get you to a destination, but
the ride is definitely different ;-)
Regarding the opinion of the commercial mw engineer is not
necessarily valid. Does he work with weak-signal
detection? Probably not. My qualifications are ten years as mw
engineer with NASA detecting spacecraft near the edge of the solar
system. That is definitely "weak-signal". The typical receiving
system at Goldstone had a noise temp of 16K at 2115 MHz and a minimum
detectable sensitivity of -185 dBm (the best system had -198
dBm). You can achieve -152 dBm with amateur equipment at
432-MHz. Typical 70cm ham station is -122 dBm without low noise preamps.

I know but with our weather temperature variation here minus 25C up to +34C
hand tightening is not enough it came loose and moisture
penetrate if connection are not tighten enough. When i wrote " too much
pressure" that's what i have in mind but the higher quality adaptor
resist much more than the cheap aluminium available on the wall. If i one
day i can get a torque meter i will be able to confirm how much
difference they can tolerate before dismantling.
BTW i'm only giving about 1/4 turn pass the hand tightening point. I measure
with a caliper the barrel thickness of the cheap metal adaptor
at .5mm and the higher quality barrel are at 1.5mm. I suspect instead of
using an O ring barrel blocking the high quality seems to have
thicker blocking ring.

The best supplier that I found on the web - from E-Bay is

They have a very large selection of RF adaptors, their prices are quite

Have ordered both Male and Female to SO-239 connectors from them.

Hi Folks,
I am trying the bird on:
9k6 BBS and Telemetry.
Does it work?
With the MSPE I can just receive numbers like:
B:45225614.
What does it mean?
I am trying to request the DIR on 1268.700 MHz, but I do not get any
response.
I am asking because I would like to see if my system works.
Is there any other Bird that I can use the 1.2 GHz Band?
Thanks in advance.

Hit o the list,
I own an Kenwood TS-790E that I used since there was KO-23 KO-25 UO-22 and
others 9600bd Satellites.
Ho you know with these birds with had to work as Uplink 2m and as downlink
On 70 cm so I have made modifies to these two bands using the ACC4 socket on
The back of the radio..
Now there is AO-51 that has the possibility to go at 9600bd, but sometimes
it has the uplink on 1.2GHZ.
Is there anybody that can tell me if I can add the 9600bd on the 1.2Ghz
module?
I need that it has to work in full duplex as the other one.
Thanks in advance for any help

Yes 7/8... and i received the same comment on AMSAT-EU forum and placing the
preamps closer to the shack will better protect them from the
WX issues ice/snow storm and winds plus they will put them away from the RF
transmit field who i suspect some desense happen time to time
causing also a lot of intermod as i'm at less than 1km from a
cellular/pagers/police/fire tower. i can see the tower light beacon from my
house window.
Thank's

It is a Heliax 45' lenght of 7/8"... and here is the the relay info's i have:
http://www.recycledgoods.com/18955_RelComm%20Technologies_RDL-2N1D4%20SR006_1P
2T%20N-Type%20RF%20Coaxial%20Relay%2012VDC%204Ghz%20RDL-
%20SR006_.html
There was some discussion about RelComm Technologies on the moon net in
2008: http://list-serv.davidv.net/pipermail/moon-net_list-
serv.davidv.net/2008-November/014898.html
If their figures are reliable i will put them in your spread sheet with the
preamps figures Icom AG-35 and AG-25 and the rig is the FT-847.
As i don't want to have an EME class station (Just working leo's) i will
probably not be able to tell the difference even if there is one
but as you said the only one way to be 100% sure is to tested it but this
will have to wait until next summer If the antenna will survive
our next 24hrs of predicted freezing rain...
Thank's for your help Ed
