[Repeater-Builder] LOOONG audio runs

I have a odd situation where I need to run long audio cables between my repeater controller and two repeaters. In this case, the repeater controller will be connected to 2 repeaters in the same cabinette. The other two repeaters will connected thru about 140 feet of wiring to the other side of a

In the united states Class C & Class D CB were always on 26/27 MHz. Class A & Class B CB was 462/467 MHz. -- Original Message -- Received: Fri, 26 Feb 2010 08:26:19 PM PST From: "Chris" To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Re: Tram Titan III 3 Information?

[Repeater-Builder] Re: New to 900mhz,, PL or DPL?

Thank you for all the replies and great information. I have another question on code selection. Other than 411 being a code used for open repeater, what is the criteria for picking a DPL code. Also it looks like PL being preferred to DPL is not RFI specific as I have seen on frequency lists

Or, how about putting old linear technology behind us, and embracing the LM2576T-ADJ switching buck regulator? You can buy this puppy ready-made for about $14: Just change the 8200 ohm resistor to fix the output voltage. The LM2576T-ADJ is rated at 3 amperes. 73, Er

Re: [Repeater-Builder] Re: Micor UHF Repeater Base 9.6 vdc current requirement?

Hi all. Built up a copy of the DC supply that was in a old Micor manual.  Used the caps and filter choke from an old supply.  Add a LM 317 with heat sink.  Added MOV's and additional hf caps.  Seemed to work fine. This fed a full micor repeater with all the normal modules.  Worst case 9.6

I was recently given a HAL "ID-1000" identifier. It's a 1RU cabinet device with connections and test jacks on the back. Seems to be diode-matrix programmed. Wouldn't mind setting it up for my call and maybe using it for something down the road. Does anyone have a manual or any idea how it is pr
