AM Antenna Problem
I have Sony stereo recever in my office. FM reception is ok, but I get zero AM. I have experimented with AM loops (the plastic loops that typically come with receivers, of which I have several sizes from receivers I have owned in the past): reception of the one station I am targetting improves a bit with a loop flat against the window glass, but not enough so to make it listenable. I tried the Terk Tower amplified AM/FM antenna - that was worse than the loops - no signal at all.
Any antennae you would recommend for this purpose? Anything I could home-brew that would be better? I am targetting 640 khz? If the building - note that this is a Fortune 500 corporation - was designed to keep 802.11bg signals in (wireless networking) - could this be part of the problem? how can I overcome it (without breachingthe integrity of the walls). Thanks, J |

Thanks, J You'd probably need an outside antenna of some kind. This station doesn't stream on the web? |
The station does stream, but streaing is blocked by the firewall at
work. It is hard to believe that there are no alternatives - I hear the station (faintly) when the loop is placed (and oriented properly) on the window sill. Is there a website dedicated to passive AM antenna design out there? The other experiment I have not tried i connecting the ground terminal lug of the recever to the electrical ground of the building, while keeping the loop tied to the othe lug. Will try that next. |
I can pick up 640 kHz on my radios.I don't know what kind of a station
it is though.I hear some Spanish music but it comes in faint.The station is either Northwest (Colorado,perhaps?) or Southeast of me. cuhulin |
Check out the new Sony gadget at, www.smarthome.com/6346.html
With that new Sony gadget,you can access your computer from your home and online radio and tv stations too anwhere in the World,or so the advertisement at www.smarthome.com claims.They sell a 7 inch screen model for $899.99 and a 12 inch screen model for $1299.99.I want me one! I think they require broad band internet access. cuhulin |
It is KFI640 in LA dude. I am 45 miles away - not sure where the repeaters
are if tehre are any. wrote in message ... I can pick up 640 kHz on my radios.I don't know what kind of a station it is though.I hear some Spanish music but it comes in faint.The station is either Northwest (Colorado,perhaps?) or Southeast of me. cuhulin |

Since their tower fell down they've been on half power through a little 150' or so stick. Why is hearing Limbaugh and Doctor Laura so important? |
David,

640 kHz is in the LA (Los Angeles) area? I didn't know that,but I Say
that is great.That shows I can pick it up at night time wayyyyyyy over here in Jackson,Mississippi,about 2,000 something miles away.I am fixin to go to the Goodwill thrift store for a while now.I need to get my junk fix. cuhulin |

That must have been the sound of that spring inside your skull breaking loose............ The frequency of 640 Khz is occupied by more stations than you can shake a stick it. I haven't looked in my station log, because it isn't real importatnt to me, but I would bet there is at least one in every state. If you think you can get a Los Angeles station in Jackson, Ms., I have a 34 tube Zenith Transoceanic I would like to sell to you. Les I've heard KFI in Houston. |
I made a typo,actually,it is a 620 AM radio station in the Jackson area
I was talking about. cuhulin |
I can easily pick up some AM radio stations in Texas.San Antonio and
Dallas and Beaumont and Houston are no sweat for my radios to pick up and neither are some AM radio stations in Louisiana (New Orleans and Schreveport) and Alabama (Birmingham) and Tennessee (Memphis and Nashville) and Georgia (Atlanta) and Arkansas (Little Rock) at night time.I can pick up WNOE in New Orleans in the day time,although WNOE does fade in and out in the day time. cuhulin |

Les I wouldn't have put it quite that way, but I do agree with Les's point - whatever station you are getting on 640, is is very, VERY unlikely it is from Los Angeles.

I made a mistake on the 640 khz statement, that is a clear channel frequency for stations with 50,000 watts of transmit power, here is the list of stations on 640 KHZ. Les Where did you get this data? WLVJ ROYAL PALM BEAC FL 7500 460 DA-2 REL 5/98 This station is on 24 hours a day and plays big band music from "The Villages" in Lady Lake Florida. It changed hands a couple years ago and is no longer a religious station. It is a pain because they over modulate and splatter the lower part of the AM broadcast band. -- Former professional electron wrangler. Michael A. Terrell Central Florida |
Well,I guess I don't know where all of the 640's are in U.S.A. I can
easily do a www.dogpile.com for them and look them up.But,the 640 AM radio station I was listening to definetly was either Northwest or Southeast of me.I know which way is North,South,East and West and in between those points of my Compass without needing to actually look at my Compass.I had the back of my radio aimed to the Northwest to pick up the best signal from that 640 AM radio station (wherever that particular AM 640 radio station I was listening to is?) because my couch faces due West and that was the easiest way for me holding the front of my radio in front of me.It would have worked the same way (it isn't rocket science,boys and girls) even I had been holding the back side of my radio in front of me. cuhulin |
I passed through Lady Lake,Florida once.Lady Lake is not far Northwest
(I am not cheating and looking it up first in my Rand McNallly Road Atlas) out of Orlando. cuhulin |
The Villages is mostly a retirement community in Florida.y'all might not
believe it,but I do have a snail mail brochure here in a clear plastic wrapper I ordered from their website.This week,I am gong to snail mail it to that married Irish woman wayyyy over yonder across the big pond.OK,now call me a liar.Oh,by the way,a few years ago,I told her she can have part of my half acre in Interchalen,Florida for free.She told me she just might take me up on that offer someday. cuhulin |
If they are playing Big Band Music all the time,Hey,that is Great! There
Should be more Big Band Music Radio Stations all over U.S.A.! on AM and FM Radio Stations.There is a Radio Station like that here in Jackson.Rock On,The Villages,Rock On,Lady Lake,Florida,Rock On! cuhulin |
I ordered the Select-A-Tenna M-541 last week, received it yesterday,
installed today and, voila - it works exactly as advertised, I can now get KFI640 loud and clear inside my office. Very hapy with it. This is in a completely different league compared to the Terk line up at Best Buy. Thanks for the tip, RHF! Namikis |
