ZL · VK · Pacific — on air now

Aotearoa's home for digital amateur radio.

DRGNZ supports New Zealand hams working FT8, JS8Call, Winlink, packet, and the rest of the digital spectrum — from first decode to building your own gateway node.

The Spectrum

Digital modes worth knowing

From weak-signal contacts bounced off the noise floor to email over HF, each mode trades bandwidth, speed, and robustness differently. DRGNZ members run all of these on a typical weekend.

WEAK SIGNAL · HF
FT8 / FT4

Structured digital modes built for working stations deep in the noise. FT8's 15-second cycles make it the busiest mode on HF; FT4 trades sensitivity for speed in contests.

KEYBOARD-TO-KEYBOARD
JS8Call

Built on FT8's signal robustness but designed for free-text messaging, relay, and store-and-forward — useful for keyboard QSOs and basic emergency traffic.

EMAIL OVER RADIO
Winlink / VARA

Send and receive standard email with attachments over HF or VHF using a Winlink RMS gateway — the backbone of DRGNZ's emergency communications capability.

VHF/UHF DIGITAL VOICE
DMR

Time-slot digital voice linking NZ repeaters into national and worldwide talkgroups via the Brandmeister network — two conversations, one channel.

VHF/UHF DIGITAL VOICE
D-STAR & System Fusion

Icom's D-STAR and Yaesu's System Fusion (C4FM) bring callsign routing and reflector linking to local repeaters, with GPS and short-message data alongside voice.

OPEN SOURCE VOICE/DATA
M17

A fully open-source digital voice and data protocol built by hams, for hams — no licensing fees, no closed codecs, gaining ground across the Pacific.

PACKET / MESH
AX.25 & APRS

The original ham data network — still running NZ's APRS tracking and digipeater infrastructure, and the base layer for emerging VHF mesh experiments.

LOW SPEED / RELIABLE
PSK31 & Olivia

Narrow, low-power text modes for conversational HF contacts. Olivia's heavy forward error correction pulls a copy out of conditions that would silence voice entirely.

CLASSIC RTTY
RTTY

Radioteletype predates every mode on this list and still fills the contest bands every weekend — the mode digital radio in amateur service was built from.

Start Here

From silent shack to first decode

You don't need new gear to start — most digital modes run from a laptop, a sound-card interface, and the rig you already own.

01

Get licensed

Hold any current NZ amateur licence. DRGNZ runs study groups for those working toward their callsign.

02

Interface your rig

A USB sound-card interface (or rigs with built-in USB audio) connects your transceiver to free software like WSJT-X.

03

Install & configure

WSJT-X, JS8Call, or your DV hotspot software — DRGNZ's wiki has tested config files for common ZL setups.

04

Get on air

Join a Tuesday net, ask in the Discord, or just call CQ. Most digital operators are glad to help a new decode along.
