[ct-user] Simple (I hope) networking question
Tue, 30 May 2000 10:05:41 EDT
As a test setup in preparation for FD, we (N6HC and W1HIJ) set up a two
station network using CT9.44 for WPX CW. Station 1 was TS950/TL922 with a
386, station 2 was an FT990 with a Pentium II. Station 1 had radio control on
com1, network on com2, packet on com3. Station 2 had radio control on com1,
network on com2 and packet remote. Everything work perfectly --- EXCEPT that
when xmitting on station 2, occasionally the computer of station 2 would
switch to 20M regardless of what band the radio was actually on and
regardless of what band station 1 was on. The switch would only last for a
second or two and then it would revert to the correct band. As a general rule
this was only a distraction, but occasionally it meant that a dupe check was
incorrect, if for example a station being worked on 15 by station 2 had been
worked on 20 but not 15. Refusal to log on 15 (i.e. the band station 2 was
actually on) because of incorrect dupe check results happened once or twice.
Station 1 never experienced the glitch and it was not correlated with
transmitting by station 1.
Suspecting RFI, we reduced power on station 2 to 10 watts and tried rerouting
all appropriate cables, none of which had any effect. Only 1 or 2 extra
ferrites were available to try, but the effect was nil as well.
Any thoughts on causes and cures?
