Re: [AMRadio] AM on Ants(forgot to ID)
Hi Brian: you should have a great signal, just get that rascal up at least twenty feet and you will be surprised, My power co sold me two new 45 Ft poles and placed them for a little under $ 900 That height models very well for all bands, yes, it is too high an angle for 80 but really good for 20 and up and certainly very usable for 80. I also found that if you have to go through a wall, my garage with steel siding and finished interior wall, short lengths of hardline make a great feed though. I used 3/4 inch and the exterior is a tight fit in holes punched through the siding. length is about 8 inches. I gave up on trying to get something in the trees!! This pulls up and down in a matter of minutes if I want to try something else. yep, 90 ft poles would be much better, but the cost becomes absurd, several $K per pole. open wire feeders are very easy to make, the round clothes hangers that sell by the 50 pack make great spreaders. cut, drill, feed the wire through,. wrap with small guage wire and cover the wrap with RTV. near zero loss. always best to feed in the center, but I am using a 260 foot wire fed 60 + feet from one end.

Re: [AMRadio] AM on Ants(forgot to ID)
By the way, Maybe I did not mention this, I am putting out about 450 watts P.E.P. with a resting carrier of 150 watts. I am working on the antenna today. Thanks for all your input.

Re: [AMRadio] AM on Ants(forgot to ID)
de N0DGN, First, a DX-60 will drive a pair of 3-500Zs with a carrier of almost 300W. It isn't important whether a SSB station mumbles about the carrier not being nulled out. An AM rig is "supposed" to have a carrier. Then the antenna issue is dependent on whether the limits of property size, tree height, and or tower/pole height aren't always what is the most desirable. If one can't afford a tower, try to contact the local power company. See if you can get a "used" pole. sometimes when they do have them, you can get them to either drop it off,, OR if you talk "real" nice, they'll bore the hole and set it for you.

Re: [AMRadio] AM on Ants(forgot to ID)
(forgot to ID myself) Also, if you are using controlled carrier AM modulation, your unmodulated low power AM carrier may be down in the mud, but your fully modulated signal is very easily heard. Sometimes the receiving end will complain about signal strength, and I think this has more to do with the type of detector in the RX, where the carriers only function is to charge the RC circuit after the detector. Controlled carrier can sometimes sound like SSB, and I used to get told all the time, when using a DX60 on 20 meters, and phasing type SSB rigs where still abundant, that my carrier was not nulled out completely.
