(meteorobs) Possible final year of tv transmitter scatter in US

[stange34 at sbcglobal.net]

Off the top of my head without thinking it out....

It might be possible to use a "pre-selector" for the old analog frequency 
which has gone digital.

That preselector would be designed for the specific frequency previously 
used but is capable of signal pulse integration with a fairly long time 
constant. The purpose of the integration is to sum the pulse transimissions 
into a reasonably flat carrier frequency for the existing receivers being 
used.....(just a quick thought). I am sure there is a way to counteract the 
move to digital...... I do not have time to work in RF with my existing 
responsibilities.
