[RF hardware limitation] Freq 390MHz Locked
[RF hardware limitation] Freq 390MHz Locked
good night, with the native radioditty program, I heard commercial frequencies in the range of 390 mhz onwards. When disabling the bandwidth limit, I am unable to subscribe to the 393,000 freq. Would anyone have any tips on how to resolve this?
Re: Freq 390MHz Locked
The RF hardware can't technically operate below 400Mhz in the UHF band.
Its possible that your radio may in operate outside of the frequency range for the RF chip, but if we were to change the range that people can select, we would probably get bug reports from people when their radio did not operate on those frequencies because their RF chips didnt work on those frequencies.

Code: Select all
const frequencyBand_t RADIO_FREQUENCY_BANDS[RADIO_BANDS_TOTAL_NUM] = {
{
.minFreq=13400000,
.maxFreq=17400000
},// VHF
{
.minFreq=20000000,
.maxFreq=26000000
},// 220Mhz
{
.minFreq=40000000,
.maxFreq=52000000
}// UHF

Good night, I understand but the question is: wouldn't the radio be able to simply have RX on this frequency without TX? In the original firm I can put that frequency to listen
