[aprssig] Has anyone else seen this?

[Rory Burke]

The D7 I'm using has battery save disabled.  When listening with the  
D7, the first one beacon from the D710 is never decoded. The second  
and subsequent ones always are decoded. I've also sat within a few  
hundred feet of the local digipeater and witnessed the same result -  
the first beacon is ignored, and the second and subsequent ones are  
digipeated.  I have parked within 50 feet of the local i-Gate. The  
first beacon is ignored. The second and subsequent ones are i-Gated.

After running further tests, I've determined that if I change the TX  
Delay of the internal TNC - Menu 601 - from the default of 200ms to  
300ms, the manual beacon is decoded first time, every time, by the D7,  
the local digi, and the local i-Gate.
