Can you transmit with SDR? It depends on the SDR. If you have the right hardware, yes you can, but not with the RTL-SDR. Some transmission capable SDRs include the HackRF, PlutoSDR, LimeSDR, LimeSDR Mini, and more.

At any rate, what is the best RTL SDR dongle?

Currently we recommend the SpyVerter as the upconverter of choice. Although it was designed to be used with the Airspy, it works perfectly with the RTL-SDR. It uses a 120 MHz oscillator, has excellent filtering and can be powered via USB cable or via the bias-tee on our RTL-SDR Blog dongles.

So too, what does SDR mean in ham radio? Software-defined radio

Next, what can you do with SDR radio?

You can do various different things using an SDR as follows:

Receive broadcast radio.
Amateur radio.
Radio astronomy.
Track ships via AIS transmissions.
Track aircraft via Mode S transmissions.
Set up a DRM transmitter.
Build a GSM network.
Experiment with LTE.

What can I do with RTL SDR?

What are some RTL-SDR Radio Scanner Applications?

Use as a police radio scanner.

Listening to EMS/Ambulance/Fire communications.

Listening to aircraft traffic control conversations.

Tracking aircraft positions like a radar with ADSB decoding.

Decoding aircraft ACARS short messages.

Scanning trunking radio conversations.
