Can visiting amateur radio operators use SCRG repeaters?

Yes. Licensed amateur radio operators are welcome to use SCRG systems configured for public guest operation, join conversations and participate in public nets.

What P25 talkgroup does SCRG use?

SCRG uses P25 Talkgroup 47366 through the MMDVM P25 network. Conventional repeater NAC values are separate settings.

Can a Baofeng UV-5R use SCRG P25 repeaters?

A standard Baofeng UV-5R is an analog FM radio and cannot transmit APCO P25. It can use the analog FM side of compatible SCRG repeaters.

AllStar status is third-party network status. Green means AllStarLink reports the node Active. Red means the service reports the node inactive. Gray means status could not be retrieved. None of these indicators proves that the local RF transmitter, antenna system or site power is healthy.

Come Talk With Us

SCRG Repeater Use & Conversation Guidelines

You do not need a technical question, emergency, club announcement or net script to key an SCRG repeater. Most of the time, the point is simply to talk. We want a system where operators can get to know one another, laugh, compare notes, learn something, argue about the best pizza in town and occasionally even talk about radios.

Food & Restaurants Sports Current Events Ham Radio Computers & Technology Video Gaming Cars & Mechanical Gardening & Planting Off-Roading & ATVs Travel Weather Local Life Projects & Repairs Whatever Comes Up

Broad Conversation Is Welcome

SCRG is intentionally permissive about normal adult conversation. Politics and religion are not automatically forbidden topics, but we ask operators not to let either subject dominate the system or turn a friendly conversation into a grievance session. Current events are fine. Strong opinions are fine. Being disagreeable for sport is not the culture we are building.

If another operator politely asks to move on from a subject, the expectation is simple: move on. There is no need to demand to know who complained, argue about a supposed right to continue, or turn the request itself into the next twenty minutes of airtime.

A Few Boundaries Matter

Hate speech, sexually explicit conversation, deliberate harassment and conduct intended to bully, belittle, humiliate or repeatedly bait another operator are not welcome on SCRG systems.

If your idea of a QSO is making somebody else the target, this is the wrong network. You may be asked to stop, change the subject, disconnect, or take your operating somewhere else.

A note about “free speech”: The First Amendment limits government censorship. It does not create an unlimited right to use privately controlled communications infrastructure. FCC rules also expressly permit a repeater to limit use to certain user stations. SCRG’s preference is to welcome responsible operators, not exclude them, but repeater trustees and control operators retain authority to manage the systems. First Amendment background and 47 CFR §97.205.

Digital Voice

Las Vegas P25 Repeaters, TGIF DMR & Network Talkgroups

A repeater tone, a P25 NAC, an AllStar node and a digital talkgroup are four different things. SCRG uses several technologies, and this section tells you where each one fits.

P25 Conventional RF

SCRG and affiliated P25-capable repeaters use conventional APCO P25 on RF. Multiple SCRG systems use NAC 702, while selected affiliated systems use NAC 293.

MMDVM P25 Network

SCRG’s networked P25 activity uses the MMDVM P25 network. The primary SCRG destination is P25 Talkgroup 47366. P25Gateway uses talkgroup numbers to select P25 reflectors on the MMDVM network.

TGIF DMR

SCRG uses the TGIF DMR network with Talkgroup 1952 and Talkgroup 42230. These are DMR talkgroups, not AllStar node numbers, even when a familiar number appears in both environments.

Programming distinction: On an analog channel you may need a CTCSS or DCS access code. On conventional P25 you use a NAC. On TGIF DMR you select a DMR talkgroup. On the MMDVM P25 network you select a P25 talkgroup or reflector destination. AllStar nodes are separate VoIP endpoints.

No RF Radio Required

Connect to SCRG Online: QSO One, EchoLink & AllStar

You do not have to be within RF range of Las Vegas to say hello. SCRG welcomes licensed amateurs connecting through supported internet-linked amateur radio systems. QSO One is especially useful because it brings AllStarLink, EchoLink and TGIF DMR into one application.

QSO One

Windows + Android

QSO One is a free amateur radio app supporting AllStarLink, Web Transceiver mode, EchoLink and TGIF DMR among other networks.

Visit QSO One

TGIF DMR

TG 1952 / TG 42230

Connect through QSO One or another properly configured TGIF client and give the SCRG community a call.

AllStar Web Transceiver

SCRG AllStar Nodes

QSO One supports AllStar Web Transceiver mode. Search for the SCRG node or hub you want to reach and connect where Web Transceiver access is enabled.

EchoLink

N4NJJ-R / 881948

SCRG-connected EchoLink access is available through N4NJJ-R, EchoLink node 881948. QSO One and the official EchoLink clients can both be used.

Visit EchoLink

Internet check-ins are real amateur radio contacts. If you hear activity on TGIF, AllStar or EchoLink, key up and say hello. Tell us where you are connecting from. One of the best things about a linked system is hearing from operators far outside the Las Vegas Valley.

Las Vegas Built. Connected to Buffalo.

SCRG Hub 42230 & Buffalo Amateur Radio Repeater Association

Hub 42230 is also part of a relationship that matters to SCRG well beyond the technology. Sin City Repeater Group has developed a warm working relationship with the Buffalo Amateur Radio Repeater Association, Inc. (BARRA) in Western New York. BARRA has served the Buffalo and Niagara Frontier amateur radio community since 1967, and its repeaters are operated as open systems for licensed amateurs.

Several SCRG members are in the Buffalo and Niagara Falls area, and SCRG Founding President Bill N4NJJ is originally from Buffalo. The connection has grown into an ongoing exchange of friendship, technical knowledge, repeater experience and on-air conversation between operators more than 2,000 miles apart.

AllStar makes that relationship easy to hear, but the network link is not the point. The people are. If you hear Western New York operators on 42230, say hello. If you are in Buffalo and hear Las Vegas coming through, do the same.

Front-Panel Programming Guide

How to Program Las Vegas SCRG Repeaters into a Baofeng UV-5R

These instructions are written for the classic Baofeng UV-5R family menu system with memory channels 000 through 127. Baofeng has sold many radios under similar model names, and firmware behavior can vary. If the keys or menu numbers on your radio do not match these instructions, stop and identify the exact model before continuing. A programming cable and CHIRP are usually faster, but every step below can be completed from the radio’s front panel on a compatible UV-5R.

Analog FM only: A standard Baofeng UV-5R is an analog FM handheld. It does not transmit APCO P25. Angel Peak and Low Potosi support P25 in addition to analog FM, but the instructions below program only their analog FM operation. Centennial Hills 445.375 MHz is also programmed here for analog FM.

Why the procedure has two saves: On the classic UV-5R, an empty memory channel is first created with the repeater’s receive frequency. The repeater’s transmit frequency and transmit tone are then written to that same memory channel a second time. This is normal UV-5R behavior. Do not create separate receive and transmit memories.

Before programming any of the three repeaters

Press VFO/MR until the radio is in Frequency (VFO) mode, not Memory mode.
Press A/B so the upper A display is selected. Classic UV-5R memory programming must be performed from the upper display.
Make sure the A display is on the UHF band. On UV-5R versions with a BAND key, use it if necessary before entering the frequency.
Turn Dual Watch off: MENU 7 MENU select OFF MENU EXIT.
Leave receive CTCSS and receive DCS OFF for this beginner configuration. They are not required to access the repeater and leaving receive tone squelch off simplifies troubleshooting.
Choose an unused memory channel. If you are unsure whether it is empty, delete it first: MENU 28 MENU choose the channel MENU EXIT. Use the same channel number for both saves below.

Angel Peak | N4NJJ | 448.325 MHz | 107.2 Hz

Radio receives:
448.325 MHz

Radio transmits:
443.325 MHz

Effective offset:
-5.000 MHz

Transmit CTCSS:
107.2 Hz

Program the memory

Complete the preparation steps above and choose an empty memory channel. We will call it CH.
Enter the repeater output frequency on the upper A VFO: 448325. Confirm the display reads 448.325.
Set transmit CTCSS: MENU 13 MENU select 107.2 Hz MENU EXIT.
Store the receive side in the empty channel: MENU 27 MENU select CH MENU EXIT.
Now enter the repeater input frequency directly: 443325. Confirm the display reads 443.325. Do not change the 107.2 Hz transmit tone.
Store the transmit side into the same CH: MENU 27 MENU select the same CH MENU EXIT.
Press VFO/MR to return to Memory mode and select CH. If the display is set to show frequency, it should show 448.325 while receiving.
Listen before transmitting. For a test, identify normally, for example: “W1ABC testing through Angel Peak.” Do not repeatedly key the repeater without identifying.

Digital users: Angel Peak also supports conventional P25 using NAC 702. The UV-5R instructions above do not configure P25. Use a P25-capable radio for digital operation.

Low Potosi / Sin City 700 | N4NJJ | 449.700 MHz | 107.2 Hz

Radio receives:
449.700 MHz

Radio transmits:
444.700 MHz

Effective offset:
-5.000 MHz

Transmit CTCSS:
107.2 Hz

Complete the preparation steps above and choose an empty memory channel CH.
Enter 449700. Confirm 449.700.
Set Menu 13 T-CTCS to 107.2 Hz: MENU 13 MENU 107.2 MENU EXIT.
Save 449.700 as the receive side: MENU 27 MENU CH MENU EXIT.
Enter 444700. Confirm 444.700.
Save 444.700 as the transmit side into the same CH using Menu 27 again.
Return to Memory mode with VFO/MR, select CH, listen first, then make an identified test call.

Digital users: Low Potosi also supports conventional P25 using NAC 702. A standard UV-5R can use only the analog FM side.

Centennial Hills 375 | N4NJJ | 445.375 MHz | 107.2 Hz

Radio receives:
445.375 MHz

Radio transmits:
440.375 MHz

Effective offset:
-5.000 MHz

Transmit CTCSS:
107.2 Hz

Complete the preparation steps above and choose an empty memory channel CH.
Enter 445375. Confirm 445.375.
Set Menu 13 T-CTCS to 107.2 Hz: MENU 13 MENU 107.2 MENU EXIT.
Save 445.375 as the receive side: MENU 27 MENU CH MENU EXIT.
Enter 440375. Confirm 440.375.
Save 440.375 as the transmit side into the same CH using Menu 27 again.
Return to Memory mode, select CH, listen first and make an identified test call.

Quick Reference

SCRG Repeater	Receive / Output	Transmit / Input	TX CTCSS	UV-5R Capability
Angel Peak	448.325 MHz	443.325 MHz	107.2 Hz	Analog FM only; P25 requires a P25-capable radio
Low Potosi / Sin City 700	449.700 MHz	444.700 MHz	107.2 Hz	Analog FM only; P25 requires a P25-capable radio
Centennial Hills 375	445.375 MHz	440.375 MHz	107.2 Hz	Analog FM

If the memory will not save: Verify three things first: you are in Frequency/VFO mode, the upper A display is selected, and the target memory channel was empty before the first save. On the classic UV-5R, those are common causes of failed manual programming.

If the repeater does not respond: Confirm that the memory receives on the listed output frequency and transmits on the listed input frequency. Confirm Menu 13 is 107.2 Hz. Make sure you did not accidentally create a simplex memory by saving the output frequency as both receive and transmit. Then consider RF coverage: a handheld inside a vehicle, hotel or reinforced building may hear a mountain repeater while still being unable to reach its receiver.

UV-5R programming section reviewed October 2, 2026. Menu behavior is based on the classic UV-5R family memory architecture. Radio variants and firmware revisions can differ; identify your exact model if the controls do not match.

Programming Terminology

Ham Radio Repeater Programming: What the Fields Mean

Output Frequency

The frequency your radio receives. This is normally the number used to identify the repeater.

Input Frequency

The frequency your radio transmits to the repeater when you press PTT.

CTCSS / PL

A continuous subaudible analog tone used to access a repeater or control receiver squelch.

DCS / DPL

A digital coded squelch method used by some analog systems. It is not interchangeable with CTCSS.

P25 NAC

A Network Access Code used in conventional APCO P25. It is not an analog PL tone.

AllStar Node

A network identifier for an AllStarLink-connected node, repeater or hub. Click published nodes in the table for status.

Talkgroup

A digital network destination used by systems such as DMR and networked P25.

CSQ

Standalone

A machine that operates independently rather than being continuously tied to the SCRG linked network.

Frequently Asked Questions

Las Vegas Ham Radio Repeater FAQ

Can visiting hams use SCRG repeaters?

Yes. Licensed amateur radio operators are welcome on SCRG machines configured for public guest operation. Join conversations, participate in public nets and introduce yourself.

What can we talk about on SCRG repeaters?

Almost any normal conversational topic is welcome, including food, sports, current events, radios, computers, gaming, cars, mechanical projects, gardening, off-roading, travel and everyday life. Politics and religion are not automatically prohibited, but we ask operators to keep them civil and avoid letting them dominate the system.

What conversation is not welcome?

Hate speech, sexually explicit conversation, harassment, bullying, repeated personal attacks and behavior intended to humiliate or bait another operator are not welcome.

What if somebody asks to change the subject?

Change the subject. A polite request to move on should not become an argument over who made the request or whether someone has a right to continue using private repeater infrastructure for that topic.

Can I connect to SCRG without being in Las Vegas?

Yes. Depending on the network and access method, operators can reach SCRG through AllStarLink, QSO One, EchoLink and TGIF DMR.

What are the SCRG TGIF talkgroups?

SCRG uses TGIF DMR Talkgroup 1952 and Talkgroup 42230.

What is the SCRG P25 talkgroup?

SCRG uses P25 Talkgroup 47366 through the MMDVM P25 network. Conventional RF NAC values are separate settings.

What is the SCRG EchoLink node?

N4NJJ-R, EchoLink node 881948, provides EchoLink access associated with the SCRG environment.

What do the colored AllStar dots mean?

Green means AllStarLink reports the node Active. Red means it does not currently report the node as active. Gray means the status request could not be completed. This is network status, not proof of RF transmitter health.

Can a Baofeng UV-5R use the P25 side of an SCRG repeater?

No. A standard UV-5R is an analog FM radio. It can use the analog side of compatible SCRG repeaters but does not transmit APCO P25.

Why are some repeater access settings not published?

A small number of systems use managed access parameters for technical, site or operational reasons. Those values are intentionally excluded from the website source. Contact SCRG for current programming when appropriate.

Do I need to be an SCRG member to use the repeaters?

Membership is not required for ordinary guest use of systems made available for public amateur operation. Individual machines may still have managed access requirements.
