Since the DC voltages for U7 are correct, and the crystal is oscillating, you most likely have a problem on the band board - either a soldering problem or if you have the 4 band board, a problem with the lead tinning or positioning on T1 and/or T2.
If you do have the 4 band board, did you position the trimmer caps initially with the slots parallel to the long side of the board? If not, do that and check again. 73, Don W3FPR On 9/25/2011 1:36 PM, K7MH wrote: > With an RF probe, I did not get any reading from the first test point, PRE > (premix) nor the latter test points in the manual. > I do get a good reading on pin 4 of P1 on the filter board which should be > the premix oscillator signal. > I do get the correct voltages on U7 on the RF board when checked per the > voltage table instructions. > > I do not get a reading on pin 6 of P1 on the filter board which should be > the premix signal output. > > Any suggestions would be much appreciated. > I will double check some things. > > Mike K7MH. > > -- > View this message in context: > http://elecraft.365791.n2.nabble.com/Voltages-for-Q5-and-U8-tp6825928p6829593.html > Sent from the Elecraft mailing list archive at Nabble.com. > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
