Mark, we have a York gas pack (a/c and propane heat)(abt 4 yrs old). When in the a/c mode and the outside exhaust fan comes on, I hear a spurious signal every 25kc or so from lf thru six meters. There may be a way to fix it... some kind of filtering maybe, but I don't want to mess with it. GL on finding something quiet....73 de Bill K4JYS PS...one helpful thing is to keep the t-stat up high so it won't run as much. Saves on the electric bill too.....hi.

I am concerned about the potential for RFI from the speed controllers, and wonder if any list members have any recommendations or recent experience (good or bad) with such units.Tnx es 73,Mark -- WA9ETWSent from my U.S. Cellular® Smartphone _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
