Could anyone point me in a direction to learn more about transmitting and receiving?

Im looking into the basics of implementing a telemetry system for my FSAE so we can get live data instead of having to wait for the car to come in and plug a laptop in. Im curious if im heading in the right direction with this community. I am aware that you need a license to transmit and that their are specific ranges that you can operate in. The files i want to transmit would mostly be CSV, or text files

Troubleshooting Help • Re: Error with SDR Sharp: «Cannot access RTL device»

No, still not working. It may be a Hardware fail?

Other SDR Devices • Re: Upgrade from an rtl-sdr dongle?

Hello and thanks for the reply.
I don't think that the "nesdr" is any better than the RTL-SDR V3, which is already a very good sdr.
An upgrade to the RTL-SDR V3 dongle would be something like the airspy or the sdrplay.
Regards,
James

Troubleshooting Help • What software to use for 100 kHz to 25 Mhz

Some time ago I purchased a SDR dongle (100KHz-1.7GHz full band UV HF RTL-SDR USB Tuner Receiver/ R820T+8232 Ham Radio) from China, see below. It looks well built and works fine between 25MHz-1,7 GHz but I am at a loss on how to get it working between 100 kHz to 30 MHz.
In the upper right part of the board I believe there is a mixer or up converter.
Does anyone know how to get this receiver to work between 100 kHz and 30 MHz?
What software should I use?
Any tip is appreciated.

New to RTL-SDR

New to RTL-SDR

I was stumbling around the Internet yesterday and came across this group . I had never heard of RTL-SDR before . Now after a full day of research and videos I have ordered one to try out . Looking forward to learning more

Trust me here in Europe its very hard to get an Stable HF Reception.
You can get some ""nesdr" from here: https://www.ebay.de/usr/nooelec?_trksid=
I dont know if the have an build in bias t.
If the have i can sell you some upconverter and Filter who I also use.
You need an Antenna for example an TECSUN AN-200 or AN200 on Ebay and If you dont want the Cable your Self the Cable for the antenna. (After 2y i gave UP and ordered the Cable from US).

RTL-SDR Discussion • Re: Icom IC-7100 Waterfall/Spectrum Scope?

And, of course a lot on this site https://www.rtl-sdr.com/rtl-sdr-as-a-cheap-panadapter/ And read all relevant pages on the site.
The alternative could be to just run a RTL as a receiver synced with the Icom.
Not sure if the direct sampling of the current V3 is good enough. I'd favour a converter.
But you need to research, there is so much, so many alternatives.

Google is good https://g6gei.site123.me/my-projects/pa ... to-ic-7100 and probably many more.
Just right for a beginner....

Help, I need to make a scanner!

Hello, I need help if y'all can point me in the right direction.

My EMS (911 ambulance) department uses 4 channels between dispatch, response, unit to unit, and ambulance to hospital communications.

All "channels" are 154.xxx and 155.xxx MHz simplex analog frequencies.

I am working on a project where I would use a RTLSDR with our report filing computer to act as a scanner. We are going to then have the feed play over the speakers so personnel can hear what's going on, etc.

I am specifically looking for a program that I can program the 4 frequencies in and the program would scan through them, stopping on and traffic, and resuming the scan until another signal is received.

If anyone is aware of a program which will carry out these functions, please let me know. I'm okay with the audio setup as I personally have a trunked 800mhz scanner program at home (unitrunker) but that program does not have the function we need for our basic VHF frequencies.

Thank you 😀
