2023年12月10日 · There is also Iridium sats on L-band that you can decode if you are using an SDR. (lots of videos out there on how so I wont waste space here.) Some voice stuff on there to. @dlwtrunked's suggestion about watching the C-Channel tab on Jaero is a good one. I've just gotten into all this myself as I got an L-band patch antenna recently.

2021年11月13日 · Oddly enough, the RTLSDRv1 L-Band patch work better with a dish... they are smaller. From bottom to top. v1 patch. v2 patch. 7 turn RHCP helix prototype 1. 7 turn RCHP helix prototype 2. (Not shown is a 4 turn LHCP for mounting on dishes - also 3D printed). Here is my v1 hitching a ride on my C-band dish feed:

2020年4月7日 · Hi All, I decided to embark on making a few test antennas for Jaero/L-Band Aero Satcoms. Here is the link to the construction notes in my blog L-Band DIY antennas for Jaero – Mersey Radar Thanks for looking.

2020年3月24日 · Sorry I am months late in responding. It is in below (uninteresting parts deleted for size). Note that the GES is HEX below (from JAERO); but "in reality", is is OCT and should be displayed as 3 digits so that the first indicates the region number (not the same as the satellite ID):

2019年11月20日 · Hello, I live in Brazil and I use a 50cm satellite dish and an external GPS antenna, to receive the Inmarsat L-band satellite. I use the 54w, I have a very strong signal. I use sdr-console V3 and Sdrsharp software to decode scytale-c and winSTD-C standard Demo. Dongle: RTL-SDR V3.

2020年10月18日 · C band yh thats my next project/dream only way seems to be a dish but for L band voice i use i home made helical about 26 turns with a airspy and L band nooelec bare bones lna mounted indoors in roof space but as i'am uk pointed at inmarsat ..helicals are no problem to make as long as you can find the correct diameter tube ,,look up some of my ...

2021年3月1日 · Hi. Does anyone own a similar antenna, and what kind of reception results does it achieve? Here is my CROSS DIPOL type antenna. I will give the dimensions of the antenna below. I'll add that during assembly I was inspired by the description and video from this page. Antenna CROSS BAND The...

2023年6月29日 · I have been monitoring Inmarsat voice and data channels for some time both at C and L band. I noticed recently (mid May) a big reduction in the number of 600bps channels on Alphasat. At the same time virtually all USAF Europe voice channel traffic moved from Alphasat to 3-F5 at 54W ( Strangely US Navy Europe traffic still on Alphasat).

2020年6月26日 · This is an update of my earlier list. Some notes: 1. I have converted IsatM2M LES to the standard convention (thought sometimes HEX is used in this service for MES). 2. Note that the LES may be remotely operating an earth station elsewhere to see a satellite. 3. Some LES numbers are used for...

2020年12月20日 · Changing it to a header of "Frequency (MHz)" would make display of things like C-Band and L-Band illogical. Click to expand... SDR# show Hz suggest to make is Hz C band/L band the DOT give idea 1500.00000 of 150.00000 or 1.50000
