If it's there all the time and without much Doppler, maybe it's a geo.

“THIS HORN WAS A PART OF CHAPARRAL COMMUNICATIONS ENGINEERING DEPT. AND WAS BEING USED AS A TEST STANDARD HORN.”
The dipole looks too small to be C band but the F type is not good for Ku. Is there an LNB in the back...
@Terryl Don't give up with Satdump, is can be reliable, I used it continuously for a month or more when STA was close. Most of the following is based on other use of Satdump but I found an RTL stick and looked at that. One problem is that there is no IQ correction to remove the zero term in...
I suppose it could be an EMC problem but it would need to be a big spike from something that couples to the lines. You could try something like a 10n capacitor across the pulse inputs to ground and/or a resistor, say 1k between inputs and ground. The resistor will drop the impedance of the...
Set FFT max to something like -40 or lower and I think you'll then see the noise floor more clearly. You've only got 8 bits dynamic range with an RTL-SDR. Try it on 88-108 to get a feel for it.
It's the same in Linux but I've never used that feature, I use WXTrack for Earth orbiters and F1EHN...
@Terryl Under the 'Recorder' tab select 'Device' and you should see your SDR in the list. Choose frequency, sample rate, decimation etc as required.
Under 'Processing' choose the pipeline wanted.
Under 'Recording' record baseband if you want to post process later (can be useful if you don't know...
Superb pics, I've put it on the list of stuff to try.
I've only used it for Syracuse beacons, Stereo A & Osiris Rex.
I found it works very well with Satdump on a local PC and SDR++ server on a remote Pi4 .
1244, 2.4m Ku TX/RX data and installation manual
Feed locations .67m to 3.8m 0.6 & 0.8 f/d
Offset angles .48-2.4m various shapes & f/d and includes reflector dimensions
Shipping info .98-1.8m Useful as it gives broken down size and weights and how many will fit in 40ft containers
Just sorting the shed. I got the stuff from a skip diver.
The arms are 1134. I appear to have 2 x 1134 complete kits but with the wrong az-els and a spare set of new feed supports. The az-els have hole spacings of 235mm horizontally (the same as 1134 etc) and 372mm vertically (too far apart for...
Thanks. That pretty much confirms that the arms are for the 1134. I also just found a couple of new kits to attach the feed to the arms (see .pdf).
I think that the az-el mounts were nothing to do with the 1134s but just happened to be in the same skip.
I'm trying to identify a random collection of dish bits from the shed, including a couple of az-el mounts that look like the ones in the attached pics. They came with a couple of Prodelin 1134 which have similar arms to those pictured and 0.8f/d feeds. The mounts don't fit the 1134. The feed...
