Apply some audio to leg 2 of IC104 and come back with result.

hard to read my schematic but applied a 1kh tone at R85 which I think connects to IC104 pin2. Heard a very, very faint 1k tone in the speaker but did not see any modulation in the output

    My first thought was the i.r.s. may be interested in a long term money making scam without proper taxes being paid..probably more than electronics involved.
  • @ Toll_Free:
    My first thought was why hasn't someone paid him a visit. I mean, his address is posted above.
  • @ beakster1715:
    Good news! I opened an appeal case after eBay sided with superhawkwss6. I also opened an IC3 case & sent that information to eBay. Within an hour they responded, reversed their decision and returned all of my money. Unfortunately, superhawkwss6 stole my CB radio and eBay will likely not suspend or close his account, but rather allow him to continue his criminal activity. I think I'll still file a report with our sheriff's dept (the sheriff is a friend of mine) though I know this type of crime isn't worth their time. This guy needs to be stopped and I'm certainly going to do my best to make that happen.
