Hello all: I am building a remote KPA100 in an EC-2 enclosure. The KAT100-2 has already been built and tested correctly.
My K2 is S/N 5717 with firmware 2.04P. Problem: All the test point voltages are nominal (+/-10%) except U1 pin 27. The voltage listed is 5.8 … I got 3.99 volts. Everything else in the section of initial tests is flawless. U1 pin 20 = 5.04 U1 pin 28 = 5.56 U2 pin 10 = 13.65 U4 pin 1 = 13.65 U4 pin 11 = 5.04 All of the other values are 0 as noted in the checklist. On initial power up, the K2 power supply voltage was 13.8 and current 0.36. Any hints on where to look for the problem? Thanks. gene WG7GW ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
