如何修复MYF8989XA？

有没有其他人看到这个，知道为什么或如何修复它？我在电池上运行MYF8989XA。当电池达到2.0V左右时，网络变得不可用，我试图传输。问题是其他设备无法在频道上进行通话。似乎低电压设备是恒定的TX。没有出现在我的ZENA调试。我没有频谱分析仪来检查它是否真的在恒定的TX。我试过了：在降低电压之前，我已经把微电脑复位了。当设备尝试TX时，它只会阻塞信道。当发生这种情况时，将微电路重置并不清楚该问题。增加电压清除问题。在无线电芯片清除问题上将重置引脚拉高。我在考虑在微MCLR引脚上放置电源监控IC。但是如果它锁住了通道，微型机不能通过将复位线拉高来清除它。我正在考虑读取VCC，如果低于2.1V，请将收音机保持在复位状态。谢谢，

Has anyone else seen this, know why or how to fix it?

I am running the MRF89XA on battery. The network becomes unusable when the batteries get to about 2.0V and I try to transmit.  The issue is the other devices are not able to talk on the channel.  It seems the low voltage device is in constant TX.

Nothing is showing up in my ZENA debug.  I don't have a spectrum analyzer to check if it truly is in constant TX.

Thing I have tried:
I have put the micro in reset before lowering the voltage. It only blocks the channel when the device tries a TX.  
Putting the micro in reset after it happens does not clear the issue.
Increasing the voltage clears issue.
Pulling the reset pin high on Radio chip clears issue.

I was thinking of putting a power supervisor IC on the micro MCLR pin.  But if it locks up the channel then, the micro can't clear it by pulling the reset line high.  I was thinking about reading VCC and if below 2.1V hold the radio in reset.

Thanks,
