[CQ-Contest] CT-17 Problem

[Tom Wagner]

There are two standard serial cables.  One is a
"straight-through" cable, the other is a "modem
eliminator" cable.  You want the former.

You can use your multimeter to see if you have
continuity on all required pins. A quick google
search yields this nice diagram:

I didn't check for accuracy, but if your cable has
the receive and transmit data reversed, you have
the wrong cable.

I presume that you are using a "real" CT-17, and
that it is powered properly.

Jeff -
Is the address set correctly in the software? I don't know what it is
for the 756Pro, the ProII is 64 hex.
There's nothing special about the cable.

measure between +4 and +5 volts.  When you turn on the CIV transcieve option
from the menu on the radio and turn the VFO the voltage should  drop
somewhat.  I have double checked to make sure the baud rate is set correctly
on both the radio and programs. I have also checked my computer and there
are no conflicts on the serial  port - COM1.

that I have for my TS850S radio control box - just a DB25 - DB9 cable. I am
using a 3.5mm mono  plug from the CT-17 to the CIV jack on the radio.  It
powers up just fine when 12 volts is applied.
