Re: 20 element fm antenna

Good for a rural area. I imagine if you turn it 5 degrees off a readable signal , it will be GONE ! :shock:

Re: August 16-22 Tropo Summary

How did the Toledo FM station get the same (long held) call sign as the Cinci AM with 50 kW ? I have seen only a fewinstances of this duplication in the US, very unusual.

Here is my report from Commerce Township (halfway between Pontiac and Milford) ;. 560, S7 and recovered mod just above noise level 570, S5 Fair mod recovered. 580, S3 no mod recoverable (tried narrowing filter a...

Still see no CP or anything about a downgrade at WMVP, on the FCC AM Querry page. Or the Radiolocater listing :shock:

Re: WMVP Downgrade

Ju I know there is a AMBC transmitter site with (maybe) 6 towers for WYLL 1160 near Joliet, They still can be heard well in the Detroit area at night, even with one small lobe in night pattern our way. Now that WCXI 1160, 15 kW has moved into my neighborhood , WYLL is no longer heard here. :shock:

Re: FM Antenna Price Inflation and Performance Deflation?

DIY antennas are my thing. But the price of wire, coax, twinlead, light metal tubing, and various insulators , have gone out of reach with the current economy. I am starting to forget "L in Ft = 468/F in MHz" !

Re: WMVP Downgrade

Just took a look at RadioLocator and the FCC AM Querry pages, and WMVP has no CP listed for this downgrade ! Must be inside info! I recall when it was WCFL. Drove past the three mismatched towers (not quite in a line) many times when I lived there. I know there is a AMBC transmitter site with (maybe...

Re: TV AMP

I would try a bigger and higher antenna before investing in a preamp. A preamp may be best for overcoming the losses of an extra long coax line from ant to TV. Like a circuitous routing for a Coax cable thru the house , before it gets to the TV receiver. An other example, when I moved to the far sub...

Re: Hum in am signal

I have worked with remote controlled Two Way Radio base stations with telco links for 4 decades+ and even a high resistance leakage on one side of a DC pair can induce hum into the audio. A "split pair" with one wire from one twisted pair in a cable, to the other wire from a different pair connected...

Re: Another antenna question

I hear the AM pretty well on my Amateur radio recievers with a 250 ft Dipole but I was looking for some FMHD reception as welll with a JVC aftermarket auto radio . Just hoping to get away from the noise on AM. The high Z input for a car radio, on the AM side, is a problem. 50 or 75 Ohm coax feedline...
