That agrees exactly with my 20+ years experience in packet radio. 300
ms TXD will almost always work where 200 ms will work only with the
better equipment. So for general use, 300 ms is a good compromise
TXD setting. For 9600 baud, 200 ms is a good base setting and 100 ms
is possible if a bit of effort is made to build a good system.
