I bought an L-Band Patch Antenna and have set up Jaero. (also ScytaleC for marine observations). All working very well thanks to Frugal Radio's clear and concise instructions. A tip I would like to share regarding maximising of your reception is to use a satellite finder app. I used one called Satellite Finder and once the patch antenna was fine-tuned my SNR is 26 -30

Thanks for another interesting video. I'm sure you've noticed that there are some 600bps channels on the 54W bird where the majority of aircraft are USAF transports and tankers. Other channels seem to be aimed at a particular geographical area, such as South America. I caught quite a few USAF VIP aircraft, including AF1 during the recent G7 summit on 600bps and 10,500bps channels.
@FrugalRadio3 жыл бұрын
Nice catch with AF1 Tim. That's fantastic! I've picked up several SAM flights in the past. Yes, have definitely noticed plenty of USAF activity on the 600bps transponders. Hadn't picked up on the geographic ones before though. That's interesting to know. I noticed several South American aircraft on the 600 channels, however I mostly monitor the 10500. A future project will be to ingest all transponders at once and set up a filtering system for certain messages. That's a longer term project though! Thanks for your support of the channel.

Just wanted to say another huge Thanks to you Rob for this Video. Finally I got this this weekend to setup my Inmarsat gear using the L-Band Patch antenna that you reviewed a few months back, after falling over all the newbie Inmarsat hurdles like the Bias-tee on/off software ( that really should have been packaged with the Airspy download ) I finally thought that I was there but no I was ripping my hair out why won't this bloody thing decode, why haven't I got any signal, dam it time to Re watch Rob's video in Inmarsat Decoding, hanging off of every word listening to every details to make sure that I had done what it was that you were talking about then finally I heard the one small ( well quiet large actually ) detail that after 2 hours of stuffing around that I had missed..............................................I had not turned up the Gain in the Airspy RTL-SDR, I did this feeling like a complete novice and bingo away we went, have now been happily been decoding Inmarsat for the last few hours with lots of interesting results including Mil stuff Thank you again Rob for a very detailed Video Note to self...............Watch twice act once. :-) Rgs Wayne.

Are you getting a good decode on the 10500 transponders? That's where most of the activity seems to be, at least on the other 3 Inmarsat birds. I've never been far enough East to pick up 143! What kind of SNR are you getting? When I get round to permanent mounting at the new place, I want to run simultaneous decodes on multiple transponders. It has worked in my experiments, but trying to keep up with all the data is almost impossible. So I'm going to experiment with text-based filtering and categorizing. I installed one of the software pieces that will do the work last night!

G'day again Rob @@FrugalRadio so this weekend just gone was my 1st foot steps into Inmarsat just using my work laptop I left it running for 12 hours until 6am this morning on a 1200BPS transponder and woke up this morning to some really interesting data but until I get "An Inmarsat Antenna" permanently mounted and installed I won't know if I can get any of the 10500 transponders or not. I'm really keen to expand my knowledge, use and decoding of Inmarsat data including looking at how the "Control" channels work I wish there was software like there is for trunking where you could just monitor the Inmarsat control transponder and when it spits out a goto frequency for a voice call the software just takes you there. I'd be really keen to know who you go with your project please keep me in the loop. Based on one of your videos I have just recently purchase a heap of Nooelec gear so as time allows with family & work I plan on putting some of it to good use. Also really pived that the database is no longer available & from the research that I've done no one seems to be able to find the code to rebuild a new one which leaves me with the question why is it no longer available it really takes away from the main software That being Jaero. You mentioned that you had a database....... I've tagged your KZbin channel you in several posts that I answered on several groups that I belong to some of which you are also a member of where people are looking for help understanding Inmarsat. The problem with this hobby is that there is so much abandoned-ware. I'm also cautioning people about just what they post up in the fear that Inmarsat will just go "Right we are encrypting the whole thing " and we will lose everything. Stay in touch. Rgs Wayne

Ok, strange. Possible that it is solar interference, but more likely just more background noise received by day. Or perhaps you are receiving reflections, rather than direct from the satellite path. Check that you have the fish pointed directly at the SAT, and are not picking up via a window reflection. Also use a shorter coax run if you can, or replace the extension coax with something less lossy. Also verify clear line of site to the satellite, eg no trees getting in the way. What antenna are you using? The RTL-SDR L band patch? NooElec kit? Modified GPS?

@FrugalRadio2 жыл бұрын
The higher bandwidth signals are more difficult to receive as they are weaker. The 600bps ones are the strongest. The 8400bps are the most difficult to pull in, as the power reduces when a transmission begins. For 10500, make sure your SDR bandwidth is correct (should be around 11-12 KHz - the whole signal should fit within the bandwidth window). You might also want to keep a close eye on the signal to noise ratio (SNR), and JAERO Eb value. Move your antenna to get these as high as possible. The stronger the signal, the higher chance of decode. Also check your volume output level on your SDR software. If the volumes light is green in JAERO It's fine, but if it is a different colour, you'll need to adjust.

If JAERO isn't getting audio, check that the correct soundcard is selected in the JAERO settings. Then check the volume slider in SDR#. If JAERO is receiving audio, you will see a green light at the bottom beside Volume. If the light isn't green, the volume is probably too low in SDR#. If it goes red, the volume is too high.

No worries. The audio is a little more difficult to set up. You tell JAERO to decode at 8400bps, and set your bandwidth accordingly. As long as you have the correct libraries installed (I don't remember what they're called), it will produce audio. I haven't made a video specifically about it. One thing to note is that the 8400 channels come and go. They also dynamically reduce power after an audio connection has been initiated. So you may hear part of a call, then see the signal lower and possibly drop completely. Have fun experimenting!
