FM Transmitter in GNU Radio with HackRF

[@EricHelgesen1]

When doing pure simulations in GNU radio you need to use the throttle block, or else the scheduler will run as fast as it can, even if the sample rate is 44.1k. That may explain the distortion mentioned at the beginning.

[@fjs1111]

You're right, if you don't use a throttle the CPU can get nailed to 100% and freeze.

I'm having a hard time understanding how the sink blocks work to actually transmit. A center frequency is specified for the sink, then how does the block modulate the incoming signal onto the center frequency to transmit?

[@georgecollins2905]

152 MHz is not in an Amateur Radio band. Only FCC type accepted transmitters can legally be used on that frequency. George CT

really very amezing sir thank you so much sir

[@MichaelVorbeck]

thx 4 top video + explaining, i worked in new gnuradio with the QT stuff and the Soapy HackRF Sink, there use SampleRate of 4e6 not 44100*100, doesnt accept and gives error results

[@01ericowen]

Unfortunately, the WX GUI is no longer in GNURadio.

[@user-hx7dc9uz6s]

Use the QT widgets

what is the solution if the sound is not clear?

[@ZacMitton]

why would use wide band requency modulation to modulate a signal thats being de-modulated using single side band Amplitude demodulation? And also, I tried it and it worked 😆

[@Sky_Pony_1_mic_sierra]

I was with you til 152 mhz was in the amateur band

how to make an fm radio transmitter using RTL-SDR hardware?

[@iamalanyang]

Since there is no builtin TX port at al. There is no way to transmit with RTL-SDR hardwar. It can only RECEIVE.

hello, how to build the UHF/VHF TV Transmitter using hack RF?

[@RadioabUse]

will try to find one.

[@brunonovais8801]

omg is missing wav source on my GNU Radio Companion

[@brhm9736]

How do I make this project work

[@brunonovais8801]

@@brhm9736 what is missing for you ?

[@adriancueto2490]

me too

[@BenCooke419]

It's under "File Operators." Stupid place if you ask me.

[@ZacMitton]

nice audio file lol
