The QuadNet Array - D-STAR, DMR and C4FM Fusion II Done Your Way!

Our Mission Statement

The QuadNet Multi-mode Digital Amateur Radio Network is dedicated to advancements in interoperability of digital voice (DV) networks. We are interested in all forms of DV available to the ham radio operator and have implemented connections to most of them. The only thing constant about QuadNet is that it is constantly being added to, changed and improved. QuadNet is open to all hams and all hams will always be welcome anywhere in our network. Please see our Code of Conduct regarding what we provide and what we expect of you while using our network.

Our History is Rooted in D-Star

QuadNet started as an open ircDDB routing network that doesn't require registration. We contend that valid Amateur Radio license is enough to operate on the QuadNet IRC Network. We do not require a special club or repeater call sign for use on the network. As long as the call sign is valid and being legally used, we fully support your use of dongles, hotspots and repeaters (both homebrew and ICOM) on the QuadNet network. The purpose of QuadNet is to support routing. Routing is an alternate method of connecting to other D-Star users. Routing does NOT require your gateway to know the IP addresses of reflectors or repeaters to which you want to connect. You uses special routing callsigns in the UR field (YOURCALL) of your radio (instead of the usual CQCQCQ) and QuadNet figures out how to get your signal to the proper destination.

For a long time, it has been understood that you can't route when you are using a mobile rig (like a hot-spot that uses a cellphone for its Internet connection) because routing uses port 40000. Well, here at QuadNet, we have solved that. You can Group Route to any Smart Group, whether you are operating from your home, or you are operating a mobile rig!

QuadNet Nets


The Amateur Radio RVer Net happens every Sunday night at 9:00pm ET (01:00 UTC DST, 02:00 UTC standard). We are going to try a weekly net for those amateur radio operators who also enjoy the RV lifestyle or for those thinking about it and needing more information about the RV lifestyle. The original net was started by Eric Udell, KN4MCE on Brandmeister DMR TG 31652. Seeking a wider audience we were granted a time slot on the Quadnet Array. The Brandmeister DMR TG 31652 will still be available for one on one QSOs between RVers. Sunday evening was selected since many RVers are already parked and making plans for upcoming trips. The net forum will emphasize amateur radio installations and operations pertinent to RVers. We will discuss travel suggestions as well as weather and road hazard information pertinent to RVers. With respect to RVs, discussions will be generic and not brand specific. RV lifestyle and general maintenance tips will be discussed. As a resource, we do participate on the Amateur Radio RVers Facebook page.

The VK1RWN DStar Repeater Multimode Net happens every Sunday 20:30 local time. This equates to 10:30 UTC April to October and 09:30 UTC October to April. VK1RWN is the only DStar repeater situated in Canberra - the capital city of Australia. The repeater is linked to the array for the duration of the Net which provides multimode access for the Net. For all night owls or early birds in the US, please drop by and say hello. The Facebook Group "VK1RWN D-Star and Picture Net" has more details on this Net and a D-Star Picture Net held on REF091D.

The QCWA D-STAR Net happens every Sunday night at 5:00 PM US eastern time (21:00 UTC DST; 22:00 UTC standard). Net control will be Daryl, WX4QZ. One does not have to be part of the Quarter Century Wireless Association to check in.

The Young Operators Digital Voice Net happens every Sunday night at 7:00 PM US eastern time (23:00 UTC DST; 00:00 UTC standard). Net control will be Danielle KE8JNU (10 years old, Extra class operator). This net is geared toward topics of interest for school age young people, either licensed or 3rd party with a licensed operator present. But even though this is focused on younger operators, all are welcome to participate. The goal is to enhance discussion of ideas while fostering the development of operating principles and techniques for young people.


The Ham Radio Rookies Net happens every Monday at 23:00 UTC. It is a digital QSY Net, starting normally on the Ontario Crosslink and moving thru 3 stops over an hour on the way to the Quadnet Array. Come and practice your navigation skills, start or stop somewhere familiar and maybe jump through a mystery stop on the way. More details and keep up to date on the Facebook Group "Ham Radio Rookies".

The Hotspot, Raspberry Pi, Single Board Computer, and ZumSpot Net (referred to as the Hotspot Pi SBC and Zum Net), meets on the QuadNet Array every Monday night at 10pm Eastern, (0300 UTC Tuesday from early November to early March, 0200 UTC Tuesday otherwise). The net discusses topics related to Hotspots, Raspberry Pi's, Single Board Computers (SBC's, as the Raspberry Pi's are), and ZoomSpots. The net takes announcements related to amateur radio first, then questions in regard to the items noted. Then, it's opened up to regular checkins. The net also has a Facebook group. Net Controls alternate between Daryl, WX4QZ and Steven, KC9SIO.


The Amateur Astronomy Digital Voice Net happens every Wednesday evening at 9:00 PM US eastern time (01:00 UTC DST; 02:00 UTC standard). Net control will be Jason N8XE. This net is focused on amateur astronomy topics such as observing, imaging, telescope making, telescopes, binoculars, an other general astronomy topics. If you are an active amateur astronomer, or just enjoy looking up at the heavens, please join the conversation. The first Wednesday of every month will focus on those who are new to amateur astronomy or looking to get started.

The Ham Nation After Show Net happens every Wednesday evening at 10:00 PM US eastern time (02:00 UTC DST; 03:00 UTC standard). Any and all licensed amateur radio operators are welcome to join us to talk about topics covered during the show. Net control stations are Andrew WA8LIV, Craig KC8VJK and Steve K8SAS. Ham Nation Website


The K5TAL - TALARC Net happens every Thursday evening at 7:00 PM US central time (23:00 UTC DST; 00:00 UTC standard). K5TAL is the club call of American Legion Post 1992, Gautier-Vancleave, MS. TALARC is the American Legion Amateur Radio Club. All hams are invited to check into the net and you do not have to be a veteran to check in. Operated as a means to communicate with other vets/hams regardless of the DV mode they have.


The Trains Net happens every Friday at 8:00 PM eastern time (00:00 UTC DST, 01:00 UTC standard). Net control will be Daryl, WX4QZ. It will discuss anything and everything related to trains and railroading, along with a railroad trivia question.


The Medical Amateur Radio Council meets every Saturday at 15:00 UTC for discussion among members and guests. This MARCO net on the Quadnet Array augments MARCO's HF-based nets and provides a mechanism for members and guests to join discussions without the limitations of HF propagation. MARCO promotes good will and fellowship among amateur radio operators, worldwide, who are professionals in the healing arts, or who have an interest in the various medical, dental and allied fields which constitute the healing arts. On-the-air network operation is considered an integral part of MARCO activity, and is conducted for the purpose of discussing and exchanging medical and technical information, and, wherever possible, to be of public service by assisting medical emergencies and other priority traffic. The first net will be on Dec. 5, 2020.

The Food Net happens the third Saturday of the month at 4:00 PM US eastern time (20:00 UTC DST; 21:00 UTC standard). Net control will be Daryl, WX4QZ. H.A.M. stands for "Have Another Meal", and you don't call us late for dinner! And considering both Field Day operations, and hamfests, you need to keep the operators and visitors happy, and not hungry.

The Multi Mode Digital Voice Net run by Jeff VE6DV happens every Saturday at 4:00 PM US mountain time (22:00 UTC DST; 23:00 UTC standard). If you can't make it to the net live, you can catch a recording of the previous weeks net at Soundcloud. If you are a Facebook user, check out the D-STAR Users group and join in on the discussion there.

QuadNet Array

Some Important Preliminaries

Be sure to look at the routing FAQ for a more detailed description of Routing. Make sure you get to the bottom line: If you don't want to do routing, you don't need QuadNet.

Refer to the getting started page for detailed configuration information.

Please only connect one system to QuadNet at a time. Also refrain from running multiple systems from the same IP address. Think of the QuadNet network as a telephone directory that has a unique IP address for everyone (and everything) that is logged in. If two different logins point to the same IP address your end will probably have trouble getting the addressed data to the correct node. Also, if a user has multiple logins from different IP addresses, the QuadNet server won't necessarily route your data to the proper IP address.

Finally, it has been reported that some gateway software can inadvertently send incoming routed data to linked systems and this can be a real problem. In the routing world of QuadNet, if you need to link to a reflector, you should instead route to a group that is linked to the desired reflector. For example QNET20 C is always linked to XRF757 C. It is always a great idea to unlink from all reflectors and repeaters when you are using routing!

Software compatible with Quadnet

There are far too many packages to list here. Google or Bing can be your friend in finding new packages coming out all the time. If you are new to this, we can recommend PiStar. PiStar supports a variety of small, single board computers, including the popular Raspberry Pi as well as most of the devices listed above. With a Web interface, PiStar is easy to configure and run. There are also links to YouTube videos on the PiStar Website showing how to set up and use PiStar. PiStar with a DVMega is an extremely popular combination and give you a true multimode repeater/hot spot. Routing on D-STAR is fully supported for both the DStarRepeater and the MMDVMHost!

Of course you can build your own system from the ground up. If you are interested in a multimode repeater/hot spot, a great place to start is Jonathan Naylor's MMDVM Git repository. This repository is in very active development and only experienced builders will be able to complete all the requirements necessary to build a system from scratch. A DStar-only repeater or hot spot can be built from Jonathan's older, but still popular DStarRepeater+IRCDDBGateway software and is available on Hans DL5DI's OpenDV repository. Again this takes some skill and tinkering to complete.

Our own N7TAE has a new system called QnetGateway that supports MMDVM and that can be easily built on a Raspberry Pi. see the N7TAE QnetGateway repository. If you have never built up a system from scratch before, this is a fun place to start, and, of course, QnetGateway fully supports routing! To gain inside information about QnetGateway, join the QnetGateway at

The QuadNet Group also offer help with your setup or help with troubleshooting when problems occur. The contact us page has several ways for you to reach out.

73 and have fun with D-STAR!
