Up to 60 simultaneous decodes are possible .. but Mike may be in
ground wave range of other stations , longer times may give better
results but would / will also take thing's back to the bad old days
.
60 seconds is producing reliable results on HF , 120 seconds may be
sufficient for 500K with 8 mins qrp back up , I observed on 15 min
tx fail to decode TA , only for the next 4 min to be decoded

It doesn't matter.
The decoding of the previous transmission can take place while the
current one is being received.
My PIC source, in 100% duty cycle mode, just sends the sequence end to
end with no gap, and the decoder had not problems with that

I notice that some Opera stations beacon at intervals shorter than
the length of their beacon, which presumably means the beacon is
running continuously.
Is this useful? It does not leave any space for the beacon station,
or those near him, to receive. Or have I missed something?
