SStran AMT3000 PLL issues

RADIODIRTYSPRINGS1700 · 2015-04-27T20:05:03Z

i got a 2004 model sstran, and the PLL is not functioning correctly. i get a carrier on 1410, and just a little fluttering on the freq i actually want it to be on. i've tried changing dipswitch settings and it doesnt work on other freqs either, just 1410. has there been any revisions since this early model? this thing has been on and off the back burner since 2007. all joints got re-flowed with solder and continuity checked for shorts. IC's have been replaced. i've done kits and homebrews that have been more successful and i wouldn't be suprised to find a break in the connection somewhere on a PCB trace, since im out of ideas otherwise. not into dropping more money for a factory repair, since 98 bucks is more than enough to pay for milliwatts and im a polak bastard farmer with not a lot of money to throw at things like this. starting to think i have a lemon

hmm, well i did just build the "$12 PLL" and it works on my freq, but theres also another signal at 1240 thats about as strong, if not stronger than the one on 1640. this is similar to whats happening to the ss-tran, only the sstran has no signal where i want it whatsoever. perhaps this is an issue with my chips? idk
