The ferrites in my BL2 (mounted at the K3 output) get quite hot at times. In warm weather or during a contest, I have a fan blowing on the BL2. I believe that rated BL2 insertion loss is for transformation of 50 ohms to 50/200 ohms (depending on the switch setting). Rarely does ladder line present either 50 or 200 ohms resistive, so actual insertion losses (heating) are greater than rated. 73, Paul W8TM ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
