This past week I got a short look at the IBM PCnet documentation. I find,
as you doubtless know, that this is a "broadband" (ie. cable TV based)
local network. Why I View With Alarmh Alarm is that it is in the six meter band,
my favorite. The PCnet carrier frequency is apparently 50.75 MHz. Since
the bit rate is 2 Mb/s, it will spread out quite a way. The thing doubtless
meets the FCC radiation specs, but they aren't very strict in terms of
an in-house PC along with weak-signal six meter reception. It would
likely wreak havoc with meteor burst reception. The saving grace could
be that a lightly loaded packet net doesn't transmit much of the time.

Has anyone had any experience with interference from PCnet? I should get
back on six packets some time soon - worked Florida that way last fall.
