In Reply to: Radio reception loss after TV digital change posted by buickanddeere on June 25, 2009 at 20:35:18:


buickanddeere said: (quoted from post at 20:35:18 06/25/09) AM and shortwave radio towers them selves are the antenna and are located on low moist soil when possible.

FM & TV towers are placed on the highest hilltops. The antenna part is just at the top and is electrically isolated from the support tower.

Just checked 810AM here two minutes ago from the truck radio in the yard. Full clarity except for the lightening strikes. There is another weak 810 in english underneath the NY 810 but I didn't take the time ferret the ID out.


Mostly correct, but there ARE AM towers that are also used for other services. This gets complicated because an AM tower is normally the antenna itself, therefore anything else on the tower has to have special treatment to isolate the thing.

I really don't understand this signal loss allegation. Other than what I posted earlier, I can think of nothing plausible.

On a side not, the radio amateurs "ARRL" have been imbattled in a losing struggle over a failed technology known as "BPL" which is "broad band over power lines" and which, I might add, should NEVER EVER have been approved by anyone for any reason. It basically turns power lines into giant noise radiators, as if they aren't bad enough already, and raises pure asch ee ell ell on SW, amateur, and other commercial radio reception. There's been a lot of "pacificaction" about "notching out" use in the amateur bands, but this does nothing for my SW listening.

Not to turn political, but the FCC did this over objections of many many people.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo. ... [Read Article]
