Hi Rich
I would give that a go.
Put the 3 EL Steppir at the top of the tower just above the thrust bearing
and then add the LEO antenna and the elevation rotator at a height you can
work at above the Steppir.
I think you would be pleased with the performance. I had done a similar
installation for years with the 2M above the Steppir without issue taking
into account all the normal tower cable running, etc.

Hi Folks,
Just thought I'd drop a quick note for a recent discovery I made for the
DIYers out there. Mini Circuits components are now being distributed
through Mouser! On Mini Circuits, a lot of the stuff may be cheap, but
usually comes with a minimum order quantity of 10 or 20 items. On Mouser
you can place single item orders. The flipside of this though is the per
unit cost is higher on Mouser, but totally worth it if you only need one or
two of something and don't want to eat the cost for ordering 20.
This could be a huge plus for microwave and other satellite projects. A lot
(maybe all?) of the W1GHZ transverter designs are based around Mini Circuits
components. There was some discussion on this list a while back about DIY
VHF/UHF preamps and I piped up about a PGA-103 based design that I like. On
Mini Circuits, one amp is $1.99, but again you'd have to buy 20 (so minimum
cost of $40). On Mouser same amp is $3.12 for 1. Much more reasonable if
you only need one or two.
I haven't checked every component that might be of interest, and I'm mostly
looking for SMT components at the moment. So far amps and baluns seem to be
cross listed, though a number of mixers are listed but 'out of stock' on
Mouser.....still that might just be stock ramp up delays if this is
relatively new for Mouser.
Just thought I'd let folks know. Keep your eye out for the 'buy on mouser'
link if your searching around on Mini Circuits page. Spread the word to
your microwave friends! If this is old news, sorry for that, I got excited
when I found it!

Yes, but with the restriction that it's only for US based customers.
Outside the US you can't order any of them via Mouser. Wonder what
MiniCircuits is thinking. We have a local distributor here and I'll talk
with them about this, because it's plainly ridiculous. --Hans

Hi Mark,
Not sure what your RF device is. I have seen windows change the audio gain
settings when it installs an update. It enables AGC for the FCD or it
resets the gain level. The signal ends up too strong and does not decode
because it distorts.
Otherwise review the method you are using to tune in the signal. Maybe that
was reset somehow.

Good afternoon everyone,
I'm trying to research what heavy duty Azimuth & Elevation rotators are
out there in the mark to hold a 4m dish.
Like the one in the below link from SPID.
https://www.thedxshop.com/rotators/spid-big-ras-heavy-duty-azimuth-elevation-r
otator.html
I do know that Alfa-SPID also make one.
The motor/controller needs to run with PSTRotator & PCSAT32. (I run both)

Following on from Zach's "buy from Mouser" email:)
We had a lightning strike here last Saturday on a tree about 100 feet
from the shack. Amongst a number of bits of kit that did not survive
intact was the trusty (old) LVB tracker.
Neither windows nor the PST rotator could see any USB serial device so I
assumed that the DLP-USB232-M daughter board had been zapped.
A quick Google search showed that Mouser stock an updated DLP-USB232M-G2
board which appeared to be a direct plug in replacement.
It arrived yesterday and, after a few driver updates, normal service has
been resumed and I am, once again, busy happily tracking the FUNcube birds.
I was pleasantly surprised that the dreaded "obsolescence" issue did not
apply here!
Have a great weekend

Good morning all,
I was monitoring 145.825 this morning and surprised to hear a data signal
at a time when I was not expecting to hear anything.
After a bit of research it turns out this was UO-11 ( I think ) FM 1K2
AFSK telemetry
Strong signal at FN25ig (near Ottawa Canada) AOS, at least when I first
heard the signal, approximately 2020-06-12 12:33UTC and LOS 12:38 UTC.
I think I am going to monitor a few passes and see if I can decode some of
the telemetry.

I went through some SatNogs observations for UO-11 that had positive
decodes, and 100% of the ones I looked at had either false positives due to
the ISS digipeater RF-Bombing the pass, or they just had gibberish decodes
of noise. There are also a few observations that seem to have very
noticeable signals - but no decodes.
Please do let us know how it goes.

I used to decode the telemetry from UO-9 and UO-11 for many years. As far
as I know, right now, the info is meaningless. It is not real data. I
assume the sensors no longer work.

Hello,
Regarding UO-11 there is an interesting audio capture on
https://network.satnogs.org/observations/1390588/
Sounds similar to sample on http://www.users.zetnet.co.uk/clivew/u2rpt.htm
UO-11 can be tracked from http://amsat.org.ar/pass?satx=uo-11

What caught my ear this morning was that the transmission was a steady
stream of 1k2 AFSK not the usual packet burst of ISS or other PACSAT's.
None of the usual satellites on 145.825 (i.e. ISS, PACSATs, etc) where in
view when I checked as to what satellites might be view. After loading an
element set for UO-11 and checked where it was, it's orbit matched the AOS
and LOS I had observed.
I won't have a chance to check this evening for passes but will be able to
have a listen again tomorrow morning.
I will see if I can decode any of datastream whether it makes sense or not.
cheers, Graham ve3gtc
