Jim: I built one years ago. Mine worked. It was one of my first
successful HB projects. It was great fun to get that thing to oscillate. I'd set the freq counter aside and listen around the xtal freq with your receiver. It may be oscillating faintly up or down a few khz from the freq marked on the rock. And it will probably be too weak for the FS meter. Good luck. Hang in there. 73 from London Bill M0HBR "jim&julz" wrote in message ... Greetings... Has anyone here actually built the MMM and had success w/ it? I've tried it 2 times on the bread board and each time ... nothing. I have followed the schematic perfectly, but I get absolutely no output at all (per the frequency counter, and FS meter). The only thing that I can think of that might be off, is the crystals that I'm using. They're not specifically transmitter crystals... just ones that I've scrapped out of junk. I was using a 10.145Mhz Xtal w/ the 30meter coil directions. Is there actually a difference w/ xtals, other than frequency? Also for the variable cap, I'm using a variable cap from an old am/fm radio... I assume this will work. I was just wondering if anyone has tried and failed, or tried and succeeded. Any help would be much appreciated. Thanks Jim |
