Yep thats the 11 meters I remember..not missing anything. I am not saying his audio is not good just it's too wide for the band being used, causing interference and sad to say illegal. If someone wants to do this get a ham ticket and run 75 meters where the guys are running old broadcast xmitters which smoke any audio you will hear on 11 meters.
Seems there may be a few assumptions here that are not accurate. The level of skill I see being applied on 11 is increasing each year while that on the ham bands goes down. Passing the test today is no indication of knowledge since it's been so watered down.
Any idea what would happen if they started making some of the wrong multiple choice answers be the correct answers for other questions on these tests? Know how many people don't even know the questions but memorized all the answers to get an extra class?
When was the last time you got on 75 and found more than one or two AM conversations going on? Try firing up on that mode outside of a 20 KHz "window" and the slopbuckets start whining quick but they can't stay out of that AM window.
Then what do you do if you find belching in the mic all the time offensive or don't like making 20 minuet transmissions and waiting an hour to get a turn? Talk on another frequency? Not likely on the ham bands. What frequency do you use when you want to take the "dragster" out to the track for some competitive fun?
With respect to the best sound coming from antique broadcast transmitters, consider the limitations of that modulation transformer before you bet the farm on this. Today I am hearing stations on 11 with better fidelity than the boat anchors could produce. Series pass modulators and pulse width modulators easily surpass the fidelity of the best old boat anchors.
On 11 I've seen an audio generator send a tone that dropped well below the audible range and proceeded to just bounce the S meter up and down about once a second and they could reach 100 KHz. bandwidth if they didn't use brick wall filtering to control the high end cutoff. Every technology is applied from digital to a rack full of analog audio gear and every rig from a Cobra 29 to a $5000 custom built Dave Made transmitter are used.
People on 11 are more and more curious about the inner workings of their electronic equipment. Unfortunately, more and more hams become untechnical appliance operators. I'm not casting a broad net over both groups or picking sides, just pointing out some not so obvious differences. You'll still find some of the dirtiest transmitters in the world on 11 and you can still find Elmer's on the ham bands with more technical know how than most of us will obtain.
