Hello Joe,

I noticed that too. I can decode FST4W-1800 if I am transmitting 50% of 
the time FST4W-300. I don't know if it works so well with low SNR. Those 
were strong signals. But clearly you don't need to have the full period 
to decode it.

I will soon have MF receive capability again. Tx is another thing... no 
idea when that could be ready, but I do not think it can be soon.

73,
Paul
