Re: [Repeater-Builder] Re: Speaker Level Mixing
Back in the sixties, I worked for a background music provider. He used dual coil speakers for his customer installations. Reason for the dual coil was: Voice coil one: was for the music which the individual area user could control the music level. Voice coil two: was for the public address system which the area user was not able to control. In the 2-way radio application, four separate radios could use the same speaker.

RE: [Repeater-Builder] Mobile Repeaters?
So from what I gather from all that replied, and I thank you from the bottom of my heart BTW for the multitude of information. So a Maxtrac one VHF and UHF will do the trick? I was looking at some of the setups on eBay that have two mobile radios (mostly Motorola) with a duplexer hooking the two radios together. Does there not have to be some sort of controller for it to work as well? Has anyone used this sort of setup and had it work the way it should? I have done some research and gotten lost in the shuffle of info on the net hence why I joined this list to get a better understanding of what it takes for repeaters to work but to also have the space I need to be able to have the van used as a command post as well.

It worked great. I could use everything at once, and the fidelity of the ham equipment through the car speakers was good. (I actually used a 30 watt stereo amplifier to obtain enough audio from the ham rigs to drive the car speakers through blocking resistors, complicating the installation some. I've attached a j-peg of the schematic, if this list will accept j-pegs. The schematic doesn't have component values, I think the resistors were 20 ohm, 10 watt, and the capacitors were 1000 uF, 50 volt. Basically I put a blocking resistor on each side of each speaker wire from each rig (actually from the output of the stereo amp). I put a capacitor on each wire from the car speaker (4 total, 2 left and 2 right) to block the DC that this audio system put on the speaker wires from getting to the ham rigs. What did you use to block the AC..(Audio) from feeding back into the other radio?... That's the trouble with most of these post, and all of them using transformers. You are still driving audio back into the other output stage. That will sooner or later distroy the audio output PA !!! I've replaced many expensive PA Moduls becaue someone pulled this number. The only way to do it right is to load each`output with a resistor, AC couple the audio (using caps on both sides of the outputs) into a mixer circuit and then amplify the whole thing. There was a little interaction between the radios, with volume dropping just a little when the second radio is turned on. I found that acceptable. But an active mixer is certainly a more elegant way to go. 73, Gary KN4AQ _ _ Gary Pearce KN4AQeditor, SERA Repeater Journal Cary, NC www.sera.org 919-380-9944 [EMAIL PROTECTED] [EMAIL PROTECTED] AOL/Yahoo Instant Messenger: KN4AQ Radio (send e-mail to be put on my buddy list) Yahoo!

[Repeater-Builder] Speaker Mixing with transformers
Here's another method... Radio Shack sells a 600:600 ohm transforer pretty cheap. Pick up one for each radio used in the circuit. You will need to follow the mixer circuit with a small audio amplifier. As mentioned before, amp kits are sold from MPJA, Altronics, Mark V Electronics and others. Motorola makes/made a 12 watt amplified speaker that might be used. Terminate each of the radio speaker outputs into a 22 ohm 5 watt resistor. Parallel one each, the primary of a 600 ohm transformer across each resistor through a 10uF non polar cap. Done on the primary side. On the secondary of each transformer used, tie one lead from each to a common ground or return point. Place a series 10K (typical) resistor in series with each remaining transformer seconday hot lead, tied to the trailing audio amplifier input. Doesn't get much simpler... cheers, skipp www.radiowrench.com/sonic Yahoo!

Re: [Repeater-Builder] Mobile Repeaters?
Same story here! About 2 years ago the transmitter for my FM commercial station (10KW) went down VERY HARD!! My full-power backup was also dead due to completely different problems. So I had to run the station on 75 watts from an exciter. We received only a few phone calls complaining. We have two translators, one heard our low power fine. The other was hearing a different station when we were on low power. It took me four days to get the main transmitter back on the air (including replacing the 100 Amp AC 3 phase fuse box!!) The back up transmitter never did come back to life and was recently parted out. It was a Collins made in 1968! A few weeks ago, I accepted delivery on a new 10 KW Harris FM/IBOC Split level system. -- Original Message -- Received: Fri, 31 Dec 2004 11:34:35 AM CST From: Chuck Kelsey [EMAIL PROTECTED] Years ago an FM broadcast station near here had their 5KW transmitter go down. They quickly bypassed the PA and ran 10 watts. Grocery stores in a 40-mile radius subscribed to their SCA store music. Not one of them experienced a problem - no complaints at all. That's my story, and I'm sticking to it ;-) Chuck WB2EDV Yahoo!

At 01:02 PM 12/31/04, you wrote: Once upon a time you could buy 6 X 9 speakers with two voice coils, each 8 ohms or so. Haven't seen one for years, but they may still be out there somewhere. Used to use one for just what you are wanting to do, run two rigs into one speaker. 73, Al, K9SI Not just 6x9s, but several sizes. Remember, Google is your friend. I plugged the string [dual voice coil OR dual coil speaker] into google and got over 26,000 hits. Here's the jewels from the first thirty: http://www.vintagevibes.net/Speakers/DVC_speakers.htm Here's a source of 6x9, 4x10 and 5x7 inch speakers at a decent price: https://www.the-direct-source.com/product_info.php?products_id=492 This web page lists prices on the DVC speakers: http://www.doubledparts.com/price_guide.htm Here's a 6.5 round one, but it's high priced http://www.ginelectronics.com/JA-Audio-dual-voice-coil-speakers.htm I also found a 10 one but who needs a speaker that large in a vehicle?
