[WriteLog] Review of last test (CI-V problems)

[Mike Mellinger WA0SXV]

I've had this problem.  Was caused by a large bypass capacitor on the
RS232 line in the CI-V interface.  Anything over 100pf or so will mess
up the 19.2kb signal enough to cause problems.

The ICOM CT-17 has no bypass on the RS232 line.  Most of the homebrew
interfaces have a bypass -- many of them .01 mf.

Well, I finally fixed the "No Rig" problem.  What was happening was that
after the rig keyed after entering a qso for a brief moment it displayed
"No
Rig".  It never caused a problem.  It happened at all power levels and
into
a dummy load.  I changed the baud rate from 19200 on my IC775 to 4800
and
the problem disappeared.  Was it the CI-V interface, the radio, or the
program?
