[CQ-Contest] CT-17 Problem

[Hisami Dejima]

Hi

I think that CT-17 is working. 
It is difficult to measure the pulse by Volt meter. 
If it is not 0V and unsteady, it will be good. 

As for CI-V of ICOM, 
it is important to synchronize an CI-V Address.
and faster baud rate is good. 

My setup is as follows. 

--- IC-756PRO ---
CI-V Baud Rate:19200
CI-V Address:5Ch
CI-V Transceive:ON
CI-V with IC-731:OFF

--- N1MM Logger ---
Speed:19200
Pnarity:N
Data Bits:8
Stop Bits:2
DTR{pin 4}:Always Off
RTS{pin 7}:Always Off
Icom Code {hex}:5C
Radio/VFO:1


BTW
LOGER32 is the good tool of CI-V troubleshooting. 
You can monitor of the data exchange by 'Radio Debug Window'.
