Hi, I had a few problems in the past (builder's mistakes hi!) with my K2.
Today, I suspect that these problem affect the AGC on my K2.... when setting up the CAL HI and LO, my actuel readings are CAL HI set at 013 and CAL LO set at 184 when U2 PIN5 is set to 3.8V. I also found she using the K2 that the AGC a little bit too generous or "exited"... hi !! I found an old post of Don giving many values with a K2 used for the the test. I set the U2 PIN5 at 3.74 like in the post and do a few measurement with 3.74V value. There are a few differences from the Don previous post, listed below (Don's settings are on the right) : RF gain Full CW U2 PIN1 = 3.77 instead of 3.74 U2 PIN2 = 3.70 instead of 3.44 U2 PIN3 = 3.73 instead of 3.42 Q12 B = 3.9 instead of 3.68 Q12 C = 7.88 instead of 8.22 RF gain Full CCW U2 PIN1 = 4.39 instead of 4.30 U2 PIN2 = 4.39 instead of 4.30 U2 PIN3 = 4.38 instead of 4.30 Q12 B = 4.66 instead of 4.58 Q12 C = 7.88 instead of 8.22 Q12 E = 4.38 instead of 4.29 Control Board P1 PIN5 = CW 3.74 CCW 3.98 U6 PIN3 = CW 3.45 CCW 4.40 Are these values are inside the normal range ? Am I too picky with my expectation ?? Hi !!
