[Elecraft] KAT100 LEDs Gone Wild

2004-11-20 Thread Unifiedtx
I thought that installing MCU1.05 there would be ample RF sampling rates taken to avoid erratic LED displays. The updated firmware seems not to be the solution. With a 50 ohm dummy load on the KAT100 output only the leftmost LED lights up and K2 SWR is 1:1 regardless of power or band in

Roy, Getting a really good RF ground for a 2nd story shack may require more than a 1/2 inch copper pipe, it may be a good ground at DC, but actually may have a high impedance at RF (depends on the frequency). The easiest thing to try is a quarter wave counterpoise wire (open at the far end

Roy; Try adding several feet of coax between the tuner and the antenna and try again. It appears you may have a voltage maximum occurring at the tuner - adding the coax will move it out a ways. There are just some impedances and feedline lengths that tuners have a difficult time
