Actually, it was Dave (KG4YZY) who did the testing.  He was using a Kenwood
TM-271A and KPC3+ into dummy load with sample port and two D700s.  The
reason for the slower decoding is the D700 uses squelch CD instead of
software CD.

What's the vintage of the transmitter?

Richard Sharp, KQ4KX has done some testing and concludes that
the better setting of TXD for his digipeaters is with a TXD of 
180ms.  His testing with a TXD of 150ms at his digipeater
measured about 9% of packets were not decoded.  At 170ms just
over 2% weren't decoded.  180ms and above was 100%.
He was using a D700 for his test receiver. 

For what it's worth.
