repeater

Hello all, I like to monitor commuter trains (the Metra UP-North line). I know they use AAR channel 62, which is simplex, but I've noticed they are repeater antennas on the posts next to the metal boxes. Is there a channel to talk to train dispatch? Or is it for Metra Police? Thanks!

A repeater near me constantly plays its CTCSS tone on its transmit frequency (70cm analog "ARES repeater"). The tone stops while it is repeating, so messages to its input frequency are heard properly. This is the only repeater I have heard that does this. Is this repeater malfunctioning? It...

I have a TKR850 repeater that has both a duplexer and a Motorola T1501AL pass/reject cavity filter in the RX path. It previously served as a business repeater in a metro area, so this made sense. It's now going to a remote mountain ranch where there is little RF in the environment and certainly...

Hello, there I was looking to build a repeater for amateur radio and came across the T800 I heard about the reliability and not a bad price on eBay and was wondering if anyone had any information on the programing aspect of these repeaters. Thank you

I had a few questions about this organization and was hoping someone on this forum page would know about it. What is the Iowa DMR User's group? What talk groups are used by weather spotters (if any), and are they only allowed to use them during severe weather instances for that purpose...

I am a user of ICOM IC-2730A. When I tried using repeater mode with UHF and VHF(left 438.000, right 145.100), it worked. Receive from right channel and transmit via left channel. But it did not work on UHF and Air Band VHF (left 438.000, right 126.100). Is there any way to enable repeater...

I need an antenna for a system that uses mostly Baofeng 888 and UV-82 radios on the 460 range. I know the band we are using is not for commercial use, but can we please put that aside for the moment and help with the following question. We have alot of employees over a large area (over 1,000...

I'm trying to figure out if there's any kind of solution to linking a UHF Mototrbo system with a VHF analog system. Neither system are encrypted, so I'm wondering if theres some kind of repeater or bridge that can link each other to allow interoperability even if its a DVRS system. Unfortunately...

Hello everyone. I was curious to see if the Motorola Quantar has a built in autopatch function. I can see in the software there is an option to enable or disable the phone patch function. I know Auto patch is very old but I wanted to give it a try just for a learning opportunity. I do not see...

Hello all I have the opportunity to buy two different repeaters.I only need one they are going to be exactly the same price I'm just wanting to know which one would have more features??? I know they both do p25 which I will like but aside from that which is better one is a quantar and one is...

Hey all! So I am looking into building a small repeater at my home, just as a hobby or really a thing to do. But I would like to go about this the proper way, I do understand the equipment I will need but the one thing I am not sure of is how to go about getting the frequencies. I am looking for...

I'm a bit new to all this so excuse me if my terminology is not up to par lol... I have a new SDS100. I joined a GMRS club who has several nearby repeaters. Upon joining the club, they provided me with the RX Freqs, RX PL Tones/TX Freqs and TX PL Tones. I entered what I think is the necessary...

Here is something I came across recently when it comes to the Radioddity GM-30 radio and the dedicated PC radio programming app (v. 2.06) -- see screenshot below for the App's about info... I've noticed that the default channel lists (database) between the radio (reset to default) and the one...

Hello, I'm wondering, when it comes to programing a radio to a ham repeater, do you set it as narrowband, mid, or wideband? Couldn't find much on it when researching. Thanks

Hey there, I have a problem with the installation of a simple IPSC connection. The master repeater is a DR3000. The peer is a SLR5500. The connection runs over an OpenVPN server and 4G (Latency under 90ms) . Attached is a setup diagram. I have programmed both repeaters and also set up port...

Hello Fellow Hams and Radio Enthisiasts, BOTTOM LINE UP FRONT (BLUF) LINK: Traveling Ham Mobile Radio: U.S. Ham Repeaters Common Frequencies - Google Drive Did you know that there are approximately 18,793 2M & 70CM Band repeaters in the U.S., which use only 1,303 frequencies? Imagine if you...

First time posting on the forum hello all im having a little trouble i hope someone can point me in the right direction im trying to connect my vertex vxr-9000u repeater to a trident raider ii extreme controller with a db25 cable with breakout board connectors on each end. This is my first time...

Hope this is the right place for this: We have a bit of an interoperability problem where I am at. (Bet you haven't heard that before.) The LEO in the county are on UHF, the FDs and EMS are on VHF analog. I'm curious what the thoughts of some of the more seasoned radio technicians are on this...

I am looking to build another repeater using the STM32 board. I have one built using two Motorola VRM 850 radios. It works great except I cannot get my Hytera PD782s to work with it. After hours of digging, I came across a thread about how Hyteras don’t work with Motorola’s converted to 403-470...

Hello, I am part of a school club and we currently operate Analog FM and P.25 repeaters, and since many of the club members have DMR-capable radios we wanted to look into setting a DMR repeater as well. We own one of the RepeaterBuilder MMDVM kits, and two Motorola CDM750s to use for RX/TX, I...
