Oh I agree on non-popular government mandated issues. In general they
are never viewed as popular. However until some authoritative branch
steps in, there is no incentive for any forward action.
Majority of hams are cheap and will buy the cheapest radio available,
then complain about the performance and lam blast the company for
producing such a product saying "hey I spent $1000 for a radio and it
doesn't have this or it doesn't do that".
None of the organizations mentioned has any regulatory authority. I
agree in many cases a "boycott" demanding better performance might work,
but there will always be "scabs" that endeavor to break the back of those
working for betterment of the masses.
To that end, just as the FCC mandated with digital TV broadcasting in the
US, "on a certain date all analog transmissions must cease". Although
there were some and still are some issues with the digital technology
both on the transmission and reception end, mostly within a few months
things quieted and are running mostly smooth. As a result we have much
better TV picture and sound today. I didn't like spending $2300 for a
new HD TV at the time but today I'm glad I did. {As as side note, if
you've not seen HD TV off of the air but only experienced cable or
satellite service, then you've not seen good HD TV.}
I view once a significant number of new low IMD radios are on the bands
we would begin to notice in improvement in conditions. Of course until
many of the old ones are retired, we wouldn't benefit from the total
advance of technology.
