I have even shut down anything that may make an RF signal, (or something like one) I shut down the LAN system/router/modem/computers (except one with satdump running on it) and all my ham gear, I still get those annoying spikes.

Maybe it's because my antenna is very wide band (50 to 3000 MHz) I can maybe fix up the antenna I had when I first started this stuff, a high wind caused some major damage to it,(blew the mast down) that's when I got the discone. I get great signals on the NOAA satellites, but not on the...

And a noise floor of -100 dBm with SDR console, so something is causing a noise problem using the satdump program. Here is a comparison. 137.1 MHZ with SDR console. And what I get with satdump, same settings on both programs.

Same settings and using the new SAWbird LNA and filter I have a noise floor of -66 dBm using SatDump.

I wish there was a SatDump forum to post possible bugs in the program, I have some strange noise problems that show up when running satdump, the spikes are only there when using that program, using SDR console or SDR++ they are not there. For troubleshooting info one of the engineers at...

WOW I almost got a full pass on M2-3 this morning. Still have noise problems.

I recommend two web sites to help you get focused in on Astra 28.2 at your location. This one will tell you the correct size dish for your location, just click on your location and it will give you a marker...https://satbeams.com/footprints?norad=39285 This one will give pointing information...

OK, after many many tweaking's of the settings I got something from Meteor 2-4 on the last pass, but it looks like I do need an LNA as the signal was very weak, will see what goes on when I get the new one (replacement) from Amazon. This is all I got.

After removing the dead unit and just using the SDR dongle by it's self, I'm getting beautiful signals on NOAA-18. I guess that filter was junk.

OK, my new SAW/LNA filter for 137 MHz died in service last night, didn't get anything on any satellite because of that, returning it to Amazon for replacement.

I'm still getting zip on the meteor satellites, again I wounder if they are turning them off when they go over North America. Great pass but no downlink audio.

I'm having some funny noise problems here, discovered by using the new LNA with the 137 MHz band-pass filter, the noise spikes come and go, sometimes they are right on top of some of the satellites down link, as an experiment I'm setting everything up on a different computer to see if that's the...

This is a screen shot of the Meteor 2-3 with NOAA-18 right next door to it. You can see that both are affecting each other, M2-3 at 137.9 MHZ (center of display) and NOAA-18 right next door at 137.9125 MHz. (to the right of center)

un-scheduling the offending satellite does nothing, it's still transmitting on the same frequency (or close to it) as the one your looking at, you can't mix two RF transmitting channels on the same frequency, it gobbles up the signals for both.

And it looks like the next few passes are not going to work too good as NOAA-18 and 19 will be right in the way, not much can be done till they get out of each others way.
