Like I say, some are doing to teach.....   some are doing them to show you that they can repair your radio if you send it to them.   Detecting "which is which" and separating them is, unfortunately, up to us.   Do take a GOOD look at the w2aew and TRX Lab channels.   A lot of handy "basics" hiding out in those two .... at least I have found.


And I will plug THIS one... right up front.   Watching him walk down the RF-IF strip with that analyzer and explaining the mixing process and then showing you the analyzer display to back it... is pretty neat.  But then... I am "easy to impress" sometimes!!!!!
