Ken: For what it's worth, I have noticed the same for years on my PowerMaster Meters that there is a bit of power drop when going thru BPF's.
In my case I use Dunestar 600's and I can see as much as 10w drop on the output of the BPF when the BPF is on and maybe a watt or so when the BPF is off. I always looked at it as this is normal. While it may be an anomaly, I wouldn't really loose any sleep as you still can drive the amp to full power. I am not so sure that the Alpha Metering circuit LED's are all that accurate to measure the slight changes in Power In and Power Out. 73 De Mike VE3YF http://www.ve3yf.com [http://www.ve3yf.com/] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
