    FCC Investigating amazon for selling "outlawed products.

    "Mission creep is usually considered undesirable due to how each success breeds more ambitious interventions until a final failure happens, stopping the intervention entirely." Your correct, it's news, no issues with that. As for radios..... The thing is the rules are written to prevent...

    If your lucky enough to live through several solar cycles you find that lots of other dx'ers have passed on by the time the next one rolls around. Work them while you can. 73 Jeff

    FCC Investigating amazon for selling "outlawed products.

    Just this month there was a blurb on KTLA about thieves using wireless jammers to disable security cameras and break into high end homes around LA. Thievery is high tech today, there are guys boosting your wireless key fob signal out to the car, starting it up and driving away. This is happening...

    Looking for info on Texas Star 350DX

    That's fine for output, it should live a long life at that level with a fan. It has the variable on the front, leave it open and control drive with the radio. Enough drive to get 200 on ssb and limit the carrier out of the amp to 60/70 on am. They will do more but its a very safe level to run...
