The VFO functions good
|
Alas, several people have had bad parts during the build. I've built four units and have been lucky so far, and two of those were the cheapest I could find. Also, one of them had the later 612 on it, which of course, worked just fine. My first contact on one was in southern GA, about 700 miles and got a 579. That was exciting, even for an old guy like me. When yours gets its voice back, I think you'll be amazed at what you can hear. During the DX contest last year, I heard a lot of European stations, and that's with my crappy end-fed antenna.? Jack, W8TEE From: "wayne.dillon@...

So, got some time on our fancy digital 'scope here at work to check out the DDS VFO and it is working perfectly (J3 adjusted to 5V p-p) so I guess it's the 49-er. When I bought it off of E-Bay it was the cheapest one at a little over $9.00 and to be honest the components were not the best (some of the 0.1 caps measured out at 0.067), I have ordered a second one from another vendor - $13.00 this time and I'm going to go through all the components B4 I insert and solder them. Could be a wonky NE602 I suppose, I have a few in stock so I'll try substitution. However, that said it did put out 1.8 watts into a dummy load when keyed. Just gotta get it to hear something now. I'll let y'all know how I make out. 72/3 fer nw es God Bless de Wayne - NQ0RP

Aw, crap! I knew that and it never crossed my mind. Gees...another year or two and I'll be able to have my own Easter egg hunt. Jack, W8TEE From: "ab1br@...

I replaced that jack with a mono type and? have audio consistently now. ?Good Luck, Jim, AB1BR
