If there is now no interference...the RF is getting into the system thru the bow xducer or it's xducer cable...

You can perform the same test setup unplugging the transom xducer and setting the console unit to read the bow xducer to determine if the RF is getting into the system thru the transom xducer or it's xducer cable...

There are only 5 ways RF (not crosstalk) can get into a sonar system...

*xducer
*xducer cable
*power cable
*ethernet system
*directly into the head unit....

Process of elimination....

Nice post Rickie! Got that personally stowed away for future reference! I really appreciate it when someone can simply things to my level!
