[TenTec] RF Speech Processor "TX IMD"

[k6jek]

I've been a ham since 1962 long before incentive licensing. There were plenty of terrible signals on the band back then. 

CW signals were raspy, chirpy, clicky, and drifty. 
AM signals were FMing, had RF in the audio, had audio distortion, and drifted,
SSB signals had terrible opposite side band and carrier suppression, bad audio and drifted.
Splatter was common.
Harmonics radiation was common, broadcasting on several bands at once.

Spectrum displays are becoming common on high end radios. This may be a boon since others may tell you when your signal is bad. Of course they'll be wrong because they don't know the definition of bandwidth but they didn't know it fifty years ago either.

And yes, unfortunately, I know that I have just described 85% of all US hams.  I would much prefer that those 85% had never been licensed, or had been required to learn and demonstrate genuine technical proficiency to become licensed (I don't care a whit about whether they know code).

Ideally, including some hands-on operation and troubleshooting.  Putting testing in the hands of people who have an interest in how many new hams there are is the worst possible way to run things.  Having a limited number of publicly-available test questions is a deplorable farce.
