RE: [Repeater-Builder] Decibel and Telewave - Sinclair type Folded Dipole Antenn
Hi guys.. This is a good thread.. I've been wondering about the decibel UHF harness for a long time. SO.. If I'm reading Chuck right, the DB UHF elements are 100 ohms.. Correct me if I'm wrong, but doesn't this mean I could pull 2 of the elements off a DB408 and make a DB404 by simply connecting the elements by equal lengths of some good 50 ohm coax to a T, and attach a 50 ohm feedline to the T?? Can this be? Tell me if this will work guys..

RE: [Repeater-Builder] COR on GM300 8 channel reciever
Hello Henry. I believe the COS on the GM300 is active LO. Open collector.. Try using something like a 10K pull up resistor tied back to 12v. Then, when the receiver hears a signal, the voltage at the junction of the 10K and pin 8 should go from 12v to near 0. Set the ICS controller to use active LO COR. Hope I'm reading you right here. 73's Russ K4RCC From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Henry Harms Sent: Saturday, January 26, 2008 4:18 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] COR on GM300 8 channel reciever I have inherited a GR300 UHF repeater reprogrammed to 440 ham bands, and I am trying to set up a ICS Basic controller.

RE: [Repeater-Builder] Help with Motorola Radius M120 - Intermittent Recieve
Hey Scott. Thanks for writing back. You did some work for me not too long ago. I sent up a spectra-tac receiver that you retuned for me while Kevin was busy somewhere. We swapped the vibrasponder tone element too. I needed 131.8, and you took what was in it and put that one back in.. Remember? Anyhoo... I got this unit about a year ago, and it looked brand new.. Not a scratch on it. Still had that new smell too. I employed it as a IRLP link radio. It's a 10w unit. I'd often try to operate the IRLP node and it would not respond. Turned out to be this unit's receiver. I opened it up last nite. Looked totally virgin inside. I cleaned the connectors where the boards(top and bottom) attach to the chassis. I had to take the lid off what I'm assuming is the VCO compartment to get at a couple of screws to lift the board. It's the shiny lid that presses down over a couple of sections inside the radio, correct? I'll open it up again this evening and take a measurement at the test point you indicated. I'll assume I don't need a signal present to make this measurement. Might be good if you could give me a pointer to location of the RX VCO coil too, so I can tweak if it's out of spec.. Is it labeled? What voltage would be considered acceptable? 7 +- 2v or so??? It really doesn't seem temperature related. The unit operates in a climate controlled room. I may send it up to you for a look if I can't make any headway, if you work on these... 73s, and thanks again for writing back. Russ From: Scott Zimmerman [mailto:[EMAIL PROTECTED] Sent: Wednesday, October 03, 2007 2:26 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Help with Motorola Radius M120 - Intermittent Recieve Russ, If the receive is intermittent, your problem is likely NOT the LO being off-frequency. An LO that was off would rear its head as sounding off frequency or poor sensitivity. I have had some problems with the LO crystals drifting as of late, but I don't think that is your problem from the description you provided. At any rate, the second LO crystal frequency is 44.645 NOT 45.645. The IF frequency is 45.10, so 45.100 - 44.645 = 455KHz. It sounds to me like you might have a broken/cracked solder joint somewhere inside the radio or that the Rx VCO is going out of lock. Does it seem to be temperature related? If so, that would lead more toward the VCO. You can open the radio and VCO compartment and see what the voltage is on the test point marked SL. It should be around 7v or so. If not, you can adjust the Rx VCO coil to get it more in-line where it needs to be.

RE: [Repeater-Builder] cor logic circuit thoughts
Not to devalue any of the excellent options presented previously, but there is also a board made by Link Communications that will give you 'micor style' squelch, and cor output. It's not real expensive, and adds these functions to any receiver. All you supply is descriminator audio and DC. Plug and play solution. http://www.linkcomm.com/squelch.html 73 de K4RCC -Original Message- From: skipp025 [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 30, 2004 4:28 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] cor logic circuit thoughts It would not be hard to add a transistor or fet stage to the cor circuit you're having so much trouble with. Even though the circuit doesn't go below ~.5 to ground, a regular series diode or two in the Emitter lead of an added transistor (with a proper series base resistor) will ensure the transistor emitter is higher than the lowest base voltage (~.5 reported). The extra transistor should then always shut/cut off. If you want to home brew a simple open squelch detected audio cor circuit, simply run the open receiver speaker audio into a 27 ohm resistor, use a simple RC high-pass network to pass audio above say... 1KHz to a basic 2 1n4148 diode rectifier circuit driving a common 2n3904 type transistor for a cor to ground logic. Use a 4.7 or higher value Non Polar Cap to Couple the audio across the 27 ohm resistor to your controller.
