prasadnoolu commented 1 year ago

Hi, i have RTL-SDR and SDR++ application to see the responce from the radiosonde, i have programmed RS41ng firmware into my radiosonde and i tried to tune my sdr++ to below frequency, but no luck **// Transmit frequencies for the Si4032 transmitter modes

define RADIO_SI4032_TX_FREQUENCY_CW 432500000

define RADIO_SI4032_TX_FREQUENCY_PIP 432500000

define RADIO_SI4032_TX_FREQUENCY_APRS_1200 432500000**

My SDR is not detecting any signal in the programmed frequency range, can anybody help me on this.

Try only one mode first, say CW only and see if that works. I don't know if it supports multi-mode transmission.

config.zip Try this config.h, transmit CW at 432.500MHz

Hi I am able to resolve the issue by changing some settings in the Hours and SDR++.

Thanks for your help. Prasad

Ok, sounds like it was an issue in SDR++ settings. Closing.
