RC, All those voltages look fine to me.
I am not certain where you found reference to 6 volts on U1 pin 3, the voltage chart in the manual shows it as 4.78 +/- 10%, so you are within normal. The <20 mv voltages can (and likely should) read 0 volts. The '<' indicates that the voltage must be less than that numerical value. some DMMs may pick up noise on their leads or otherwise show a small voltage when no true voltage actually exists, so the manual figures try to allow for that occurrance. 73, Don W3FPR > -----Original Message----- > > KX1 ser #1056 > Alignment and Test Part I. > pages 28 and 29 > ~~~~~~~~~~~~~~~~~~~~~~~~~ > everything checks out ok > ~~~~~~~~~~~~~~~~~~~~~~~~~ > > I am however concerned about the voltage checks. > U1, pin 1 5+- 0.25 Vdc........read...4.87 > U1, pin 3 6+- 0.25 Vdc........read...4.87 also ( this one bothers me ) > D2, anode: Supply Voltage.....read...13.36vdc > D2, cathode: Supply Voltage-0.3 Vdc aarox ..read.. 13.06 > > ~~~~~~~~~~~~~~~~~~~~~~~~~ > I am however concerned about the voltage checks. > D2, anode: <20mV AC rms....read... 0 > D2, cathode: <20mv AC rms ..read.. 0 > U1, pin 1 <20mV AC rms....read... 0 > U1, pin 3 <20mV AC rms....read... 0 > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > ANd I did use 3 differant DMM to confirm these readings > ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ > Any advice accepted tnx de "rc' kc5wa > > _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
