Rather than hum, it sounds like noise on the sidebands of the signal -- becoming less broad as the distance between the K2 and the amp increases. This is easily heard when you monitor your transmitted signal on another receiver. The K2/100 is absolutely clean barefoot.
Perhaps the field from a hypersil xfmr is greater than a "normal" xfmr. Both Alphas I have tested my K2 on, at home and at a friend's QTH) have hypersil HV xfmrs. I even removed the KPA100 and ran my 10-watt K2 into the amp with the same noisy sidebands occurring on its CW and SSB output. There IS a problem! 73, de Earl, K6SE _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
