I only had a technicians license, never wanted to talk to people, just play with the toys.
It makes sense, if you have issues with cheap power supplies giving garbage messy signal, think about it rough off a winding with literally no concern if it is dirty, just needs to put watts to water.
I had to be careful when working on peoples gear back in the day, my lil shed in the back of the house was close to the antenna pole, well, like 50 feet, but had line of site. Bob liked watching Dr Who on the PBS out of Petaluma, so it was a bit of a trash signal by the time it got to our lil ghetto. If I did not have the full Faraday clothe up, it would just destroy the reception. Mainly from me always playing with yep, messy multi Kw signals...
I finally got an oscillascope, old Tube type HP unit... When I saw what I had to do to clean up the messy signal, I was shocked i had ever done it.. then I scoped one of my older units.. shouldn't have been shocked, signal was garbage... Ended up doing a ghetto recall had dozens of truck drivers showing up to get their units swapped out. I could not just let that mess go...
