[WriteLog] Rig Interface HELP - Icom IC-746 Question

[Gary AL9A]

Clay,

Do you have anything else connected to the CI-V bus?  There has been a long 
running thread on the IC PW-1 reflector about data collisions on the CI-V 
bus caused by the PW-1 polling the radio periodically to see if the 
frequency or band has changed.  These polls can conflict with the 
communictation between the radio and the PC.  From comments in that thread 
it appears that Icom's design team only anticipates handling Icom to Icom 
communications on the CI-V bus and makes no provision for data checking on 
packets sent over the bus from a software program.

Having said that I have never experienced the types of drop outs in WL that 
you are seeing, but then I've never used WL on VHF/UHF.  What is your serial 
port connection to the CT-17?  Are you using a native serial port on the PC 
or a USB to serial adaptor?  Have you tried some torroid cores on your 
interface cables to chole off any stray RF?  Sorry I can't offer more help.

73,
Gary AL9A
