I experienced the 50Hz warble on received signals when I used the 25A power supply on my newly-built K2. I constructed a 3A-supply using the Linear Technology LT1085 and, most importantly, a toriod transformer. The supply can be stood on top of the K2 without any problems. I've since tested a switching supply which also gives no problems. Several K2 users have complained about poor modulation reports. Many of my contacts have given my rig unsolicited good comments on the modulation quality. I'm wondering if it can be attributed to the very good regulation of the power supply - only 50mV (in 15V) drop at 3A. Or perhaps it is the MD-2 microphhone (now discontinued) in combination with the K2s excellent design?
