Default Converter ac noise

Hi all
My new apex 26ft trailer converter is generating lots of noise.Just with trailer plugged in at house,It generates noise on my hf receiver in my hamshack.
Today i hooked up oscilloscope and my old ts440 txc in trailer.I monitored ac line on scope and get lots of noise when transmitting.without tx,the noise level in rcvr is s-8.I guess i need some good ac line filters to get rid of this noise.
Has anyone else had this problem?
Bob

Welcome aboard.

I haven't had any noise issues from the converter. Had one LED light that spewed some junk but it failed in short order. Are you running the rig off coach 12 VDC? I usually run my Kenwood TS570 off either a car battery or an Astron M35 power supply. No noise problems.

I have at one time or another on my ham radio career put ferrite chunks on just about everything.
