Spirit1跳频导致频偏

使用调频后导致发送的连续波频偏，CHANNEL_SPACE 是100K，一个通道偏差2.5k.直接修改基频的频偏很小。

void channel_jump(uint8_t ch_nums)
{
    do
    {
        for (volatile uint8_t i = 0; i != 0xFF; i++);

        SpiritRefreshStatus();

    }while(g_xStatus.MC_STATE != MC_STATE_READY);

#if 1  


  SpiritRadioSetChannel(ch_nums); 
    SpiritManagementWaVcoCalibration();

#else

   xRadioInit.cChannelNumber =  ch_nums;
     xRadioInit.nChannelSpace = 20000;
     SpiritRadioInit(&xRadioInit);

#endif
