I actually love the L band SDRX, both the full board version, and the stand alone - it’s the most stable of all SDRs I’ve used in that band. HackRF, and many of the other pricey SDRs don’t come anywhere near it for sensitivity and stability.
It’s a great SDR to use for quite a bit of action on the L band, esp with the onboard LNA. I use mine to play around with a few sats in the band. Whilst I can’t list the specific software (as border to border, laws are different) - there’s some fantastic software about for various things you can do with it. Examples -
There is a myriad of free software for decoding the open-to-all SDR ECG messages. Marine warnings and alerts are plotted live on maps, interfaces are great with most decoder software titles.
Emails sent via some…cough satellites on the L band (not to name any) and the various Telcos on multiple channels are not encrypted, and some of the software packages will literally just beep as your (or someone else’s) inbox fills up.
AERO messages (JAERO software) appear swiftly, and the software triggers a search of the database to find which aircraft type/company is sending the message. The program interprets various code, and is quite interesting to watch.
Freight companies, shipping, aircraft, emails, warnings, SOS, Military exercise warnings, the list goes on. That L band SDRX receiver is brilliant - I love mine.
You don’t have a useless bit of hardware, you’ve got a very stable and sensitive L band receiver, which can be easily modified to be a fantastic wide band SDR.
