Well I thought I was going to be coming on to post what I'd found with the VFO problem...but now, the Info 080 is back. As far as the VFO, I discovered that if I removed the two screws that connect the control board and front panel board (so that they're not drawn snug to each other), the VFO works. It almost seems like the back of the optical encoder board is somehow shorting to the control board? I don't know...I put a couple pieces of electrical tape on the back of the encoder board and gently connected the two together with the screws and the VFO was still working.
At that point, I went back to the Part 1 tests and alignment, and started working through Part 1 and Part 2 again. Everything was once again fine up until the exact same point - when I switched bands to the 80 meter band, before tuning to 4000.10, the Info 080 message popped up again. I said several things I won't say here, then proceded to do the frequency counter check anyways just to see where I am. I didn't actually make a note of the value but the frequency was somewhere around 10800, a range of 8 to 10 MHz is specified so this would be marginally acceptable (?) I guess. Just out of curiousity, I went ahead and checked the voltage on the left end of R30 (as described in the next step) and found it to be almost exactly 0.00 V - and adjusting the slug inductor made no difference. Prior to the reappearance of the Info 080 message (but before the VFO working again), I had checked this value, and again didn't write down what the exact numbers were, but I had some sort of reading and was able to make adjustment over a wide range using the slug inductor. Finally, I tried restarting the radio (figuring I knew what would happen), and the Info 080 message appeared immediately at startup, and I noticed that relay activity is one again nonexistant. Now I'm rather discouraged. I didn't check further but I wouldn't be surprised if I'm once again seeing the same problems with voltages on U1 and such. Knowing the little bit I know about computer troubleshooting, it seems that I can narrow the problem down to something that's resulting from the switch from 40 meters to 80 meters while doing frequency counter checks...but I have no clue at all what that problem could be. My best guess, since relay activity comes and goes with the Info 080 message, and these problems start when I change bands during these tests, is still some sort of problem with U1, as I've been over solder connections several times. -- View this message in context: http://elecraft.365791.n2.nabble.com/Info-080-message-started-with-RF-Alignment-and-Test-Part-II-tp7564545p7564649.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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
