Hi: My K2 #6425 was ordered in February and is now fully operational, with almost all measurements and checks within limits. The only issue is the output of the 8V regulator, which is at 7.56V (5.5% down from the nominal 8V). If I am right, this low voltage is the cause for...
a) AGC threshold adjustment: U2 pin 5 voltage only goes up to 3.62V, not 3.80V; b) S-meter adjustment: Can never get S-meter LED below #2 or above #9 to turn on. I had to order some spare parts from Elecraft, and to be safe I asked them also to send me a tested replacement for the 8V regulator - which is on the way. My questions are... - Wouldn't the low 8V level be the cause of the above symptoms (a) and (b)? - Any reason I should or should not replace that 8V regulator, anyway? 73 - Kristinn, TF3KX -- View this message in context: http://www.nabble.com/K2%3A-Low-8V%2C-and-adjusting-AGC-and-S-meter-tp17179721p17179721.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
