I live on a boat. The Automated Identification System (AIS) is great to have on a boat. If you don't have a transceiver to send AIS packages, you should at least be able to receive and display AIS targets on your chart plotter. An RTL-SDR is the cheapest...
Setting up a SDR toolchain can be kind of a pain, in all my experience. Start Here The very baseline to start with is Nooelec's getting started guide for their RTL-SDRs. You should be able to set up CubicSDR with those instructions/driver installations,...
I’ve been working more on writing firmware to test the transceiver modules. Although I couldn’t locate any ready made libraries to drive this particular IC, there were a few none the less that helped to guide me in the right direction. Those libraries...
It's kinda shame to be RF engineer and not own a decent spectrum analyzer... Well, it's on my Christmas wishlist since I was 10, but noone bothered to buy me one so far. RTL-SDR was interesting tryout, but definitely not satisfying enough. Luckily, my...
Amateur, or ham radio operators have always been hackers. For much of the early 1900′s, buying a radio was expensive or impossible. Hams would build their own rigs, learning electronics and radio theory along the way. Time moves on, but hams keep hacking....
Things are rolling along, slowly.I've mostly been doing planning and testing, which involves a lot of running up against my own limitations. I have decided to isolate the RTL-SDR and upconverter boards from the computer (read: noise source) as much as...
48 byte packets are flying accross from TX to RX. my RTL SDR looks busy with 4GFSK at the correct frequency ! I tried bit shifting >> 24 to uint8_t and back again <
We have set up a short video to show 2 features at the same time:GollumRF JavaScript Engine andRF Jamming.We used a RTL-SDR dongle + CubicSDR as a spectrum analyzer to visualize the original frequency used by the remote control and the jamming frequency.The...
Hey!! Made some good progress since last check in on the hardware prototype devices.I received my ATAES132s, and I finished wiring the SubModule board! I threw some OLED test code on the Zero and ran I2C Scanner to verify everything is happy on I2C....
I made the PCB for an SA612 mixer module and assembled the first test build. The only thing missing is the LD1117 regulator so I am just powering it from an external regulated supply.All seems to be working well, although only tested up to 50Mhz until...
So, those oscillator parts? Over fifty bucks each. Not exactly pocket change. Unfortunately that invalidates the idea of this being the literal opposite of an RTL-SDR - I was aiming for in-the-cart cost no higher than $20.This week I got some time on...
Reflashed the RPI4 and used this info to try and get more consistent results as well as have a location to store the images. I added the website to the project under "Images Server". This is just a basic website that tracks the next satellite it...
You may find several resoureces on the web where people tried to decode Bresser Weather station data with an RTL SDR Stick.In my opinion running a Rasp Pi just for decoding some RF Weather data is a overkill of resources.There ought to be a smarter solution!!!The...
The keyboard panel was reworked, the 4 port USB hub was removed and in it's place the eth0 port was placed. A storage compartment was added to house a 1 tb ssd and rtl-sdr antennas. Supports were added to the keyboard panel to give it a more sturdy feel....
2.4GHz WiFi Pros - Building wide coverage. Lots of bandwidth. Cons - Mains power needed for most off-the-shelf low cost boards. Low power would need a custom build in all probability. Security is a concern unless upgrades to WiFi includes a segregated...
