Indeed. I've had problems with ICE 196 receiver protectors for several years. I assume the intermod is generated by the diodes in those devices, though I do not know that for a fact. The problem occurs on nights when propagation is very good both in the AM BC band and shortwave in the 5-7 MHz range. I get some extremely strong SW BC stations on good nights. All are well below the threshold but the combined affect of many signals is too much. Removing the ICE 196 clears up the intermod, so I am reasonably certain that is where it is generated. I need to either find another way to protect my front end or use band pass filters.
Sorry... I should have noted this is using Beverages +/- 600 feet long. 73, Paul N1BUG _________________ Topband Reflector Archives - http://www.contesting.com/_topband
