Hi all, Having received and fitted the replacement voltage regulator that solved my previous K1 problem, I've moved on to the first DC checks on the RF board (page 30 in my manual.)
I'm performing the checks with the board connected to a stable supply at 13.8 volts. The first two checks pass fine, but the second two state that I should be reading between 3.8 and 4.2 volts on U3 pin 5, and between 7.6 and 8.7 volts on U3 pin 6. I'm actually measuring 3.66 volts and 7.54 volts, respectively. Normally these might count as 'close enough', but given the quality of the manual (and my soldering!) I'm inclined to think I've gone wrong somewhere! Can anyone offer a suggestion as to what I might have done? Thanks and 73, -- Mike, M0PRL. ______________________________________________________________ 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
