Hope there are some 2-C experts out there who can give me some alignment advice:
First Question: For step A on page 18 of the manual, to center the 50 KHz BFO, my generator doesn't go down that low, so I set it to 100 KHz and cap-coupled to pin 1, V5 and got a audio note, presumably from the 2nd harmonic of the BFO. Adjusting T-11 zero beat the note. Seems like this is pretty similar to using the 100 kHz crystal calibrator procedure at the end of the first paragraph. I just need to see if I did it right. Second Question: On step D (VFO alignment), they mention "sliding the dial". I think they are talking about simply sliding the the vertical hair-line, but is there any way to adjust the main frequency dial independent of the VFO to get it right on the money (with the hair line centered)? Maybe this would be over-kill....I am only one division off the same direction on 3.6 and 4.0 MHz. Thanks very much. I have a cople of 2-C's on the operating table, I have stripped this one, it is back together, and working. Just need to touch up the alignment, and paint the cabinet. BTW, the three crystal oscillators were all perfectly on the money. 73, Mark N5KAE _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
