Tx Block(Sink) does not support sample rate above the 2MHz

ztamosevicius commented 6 years ago

Sample rate above 2MHz is definitely supported. Why such a conclusion?

rd15armas commented 6 years ago

OK. I tested again and I have a request from you Please adjust the sample rate 4M in FM transmitter.grc and FM Receiver.grc and see the result with your own eyes

ztamosevicius commented 6 years ago

When you change sample rate in LimeSuite Source (RX), you have to change sample rate in Low Pass Filter and WX GUI FFT Sink blocks too. You have to adjust Decimation and Interpolation parameters in Rational Resampler block as well.

Check an example screenshot attached: image

Ok Please check the screenshots attached: Where am I doing wrong..

FM_transmitter.grc.zip

screenshots 1: sample rate=2.49M 249

screenshots 2: sample rate=2.5M 250
