1. Page 48, Setting the AGC Threshold, the manuals calls for adjusting R-1 for a reading of 3.80VDC on pin 5 of U2. The highest R1 would adjust to is 3.60VDC. 2. Page 48 Bargraph Current test. The manual calls for a current reading Of 0.16 to 0.18. My K2 reads 0.25 amps. That is quite a bit higher than what is called for. Any suggestions? Are these readings anything to worry about? -- Hi DW, I'll take a stab at your low AGC measurement. In the past few months a couple of builders have had marginal +8V regulators on the CTRL board. It's unlikely this would be causing the higher than expected Bar-graph current measurement, it is possible. 73, Gary KI4GGX K2 #4067 _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
