Brutish Sailor Posted October 22, 2013 Share Posted October 22, 2013 Ok, so heres the issue. Doing research now. Tuned into a station (clear as day) and great reception on my digital dial. NOW, I try to "seek" it through the seek button, and its a no-go. http://www.youtube.com/watch?v=qozBR65-sfQ Any ideas here? Broadcasting mono via Yagi antenna.

GKIye Posted October 22, 2013 Share Posted October 22, 2013 Rob, Watching the video it looks that the classical station is the issue - On FM there can appear mirror frequencies = This is not legal, but possible (sources can be anything, ... but also for example the weather : example = if too hot ... or a transmitter who has a bad setting etc etc) - a mirror on a specific frequency multiplies in space ... example = mirror A at a range of 2.20MHz doubles to mirror B at 4.40MHz etc ... important both on the right and left side of the frequency spectrum - depending on de power (KW) of the transmitter of that classical radio station the range can expand ... - Check Your video once again ... To my point of view the difference of the mirror to Your frequency is lesser than 1MHz (Right or wrong ?) - So far ok ... - but a stereo frequency at FM "needs a space" to transmit ... That space is to both the left and right channel 0.75MHz times 2 = 1.5MHz of needed space to create a comfortable transmition and reception So two stations has to be separated from eachother with at least 1.5MHz, but in reality 2 stations don't affect eachother if they have a bigger space Conclusion : if station A is at 90MHz ... the nest station has to be at 91.5MHz ... However 91.8 would be better etc etc Practical : if 90MHz is the main frequency, but it is using in reality "space" from 89.25 untill 90.75 MHz to transmit a stereo signal Visit and listen @ BW !

GKIye Posted October 22, 2013 Share Posted October 22, 2013 I did some WIKI This is what You need to transmit : http://en.wikipedia.org/wiki/Dipole_antenna and not a Yagi antenna Yagi was mainly used as "reception" antenna for TV, to transmit it broadcasts a signal in "only one direction" Check picture : Yagi : http://en.wikipedia.org/wiki/Yagi-Uda_antenna This gives You an idea of my explanation : http://en.wikipedia.org/wiki/FM_broadcasting This is how it goes at the USA : http://en.wikipedia.org/wiki/FM_broadcasting_in_the_USA Visit and listen @ BW !

PapaBearPW Posted October 22, 2013 Share Posted October 22, 2013 I don't know for certain, but could it be that the seek function only stops on stereo channels? The ones it did stop on all had ST shown in the top right of the display. Edit: Oh. So it may have something to do with the antenna you are using to transmit with? http://www.lunarcaster.com Link to comment Share on other sites More sharing options...
Brutish Sailor Posted October 22, 2013 Author Share Posted October 22, 2013 I would kinda agree against the Yagi, but the location I was at? LIKE.....30 miles away from site. Thats with an IPO of 135. It kicks some ass. Considering it reaches from East county to the Shores of San Diego, not bad. Its a shively 6025, and it got the green light from the manufacturer as an FM antenna (they field tested it at site) Keep in mind, were broadcasting in mono, (from a shoutcast server, going to transmitter) But even around site, same thing. Papabear: One of the neigboring frequencys I locked into was in mono. By therory, ANY carrier signal can be locked into on Seek. I can lock into my FM reciever pluged into my truck, staticky because its too far away from the antenna, but this? clear signal, and no lock.

PapaBearPW Posted October 22, 2013 Share Posted October 22, 2013 I understand that. I'm just not too sure how the seek works. I would think it would simply lock on to the next strong signal it finds. I just don't know if there are different modes of seek for example. As to the antenna, I don't see why that would be an issue either. If you are receiving the signal clearly when you manually tune it in.... Odd problem indeed... http://www.lunarcaster.com Link to comment Share on other sites More sharing options...
PapaBearPW Posted October 22, 2013 Share Posted October 22, 2013 Maybe it has something to do with polarization? Is the antenna set up for vertical or horizontal polarization? If the fins are horizontal, you could try turning it 90° so that it radiats vertically as AM and FM radio use vertical polarization...just a thought. http://www.lunarcaster.com Link to comment Share on other sites More sharing options...
Brutish Sailor Posted October 23, 2013 Author Share Posted October 23, 2013 Its actually tilted on its axis. 45 degrees. HMMM. interesting concept. It would cost a ton to change its configuration, once you do, the FCC requires a licensed engineer to verify its position true, and We would have to re-submit paperwork (FCC req for full powered station) KNSJ.org / 89.1 FM San Diego Link to comment Share on other sites More sharing options...
PapaBearPW Posted October 24, 2013 Share Posted October 24, 2013 If you ever figure out what the problem is, I would be interested in hearing about it. http://www.lunarcaster.com Link to comment Share on other sites More sharing options...
James Posted February 17, 2014 Share Posted February 17, 2014 I think you can Google about this problem and there are lot of experts available who can solve your problem. Thanks WHy are you bumping up a topic from last year to just say "Google it?"
