Topband: Furnace RFI

[lmlangenfeld]

We are in the market for a new high-efficiency furnace, and I note that many (if not most) of the current models use variable-speed DC blower motors.  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
