Have you got the "SQE Test" turned on on your transceiver? You have to
turn it off if you have the transceiver connected to a repeater (which
is probably what your DEC hub is). What the SQE test does is send a
test signal after every frame, to test the collision detect circuitry,
but the repeater will see this as a real collision and will send a jam
signal.
