This guide covers installing WPSD, connecting Wi-Fi, choosing a UK hotspot channel and matching the radio.
438.7750 and 438.7875 MHz are listed as alternatives if the preferred channels are unavailable. Listen first, use low power and always check the current RSGB 70 cm band plan ↗ before transmitting.
Follow these steps in order. Get one network working before adding others.
These values describe the RF link between the radio and hotspot. Set up the channel before talkgroup routing.
WPSD uses DMRGateway. Your primary network keeps the ordinary talkgroup number; a non-primary network uses a seven-digit radio talkgroup beginning with its prefix.
| Network | Prefix | Radio contact format |
|---|---|---|
| Primary network | No prefix | The normal talkgroup number |
| BrandMeister | 2 | Seven-digit number beginning with 2 |
| System X | 4 | Seven-digit number beginning with 4 |
| TGIF | 5 | Seven-digit number beginning with 5 |
| XLX | 6 | Seven-digit number beginning with 6 |
| DMR2YSF / DMR2NXDN | 7 | Seven-digit number beginning with 7 |
| DMR+ / FreeDMR / HBLink / custom | 8 | Seven-digit number beginning with 8 |
| Automatic custom rewrite | 9 | Seven-digit number beginning with 9 |
Example: if System X is not the primary network, its Talkgroup 2350 is selected from the radio as 4002350. If System X is primary, use the ordinary 2350.

Change one setting at a time and keep a saved profile from the last working state.
Try the hotspot's IP address from your router's connected-device list. Check that the phone or computer is on the same network and that a vendor image has not changed the hostname.
Recheck that DMR is enabled, Apply Changes completed, the master is reachable and the correct hotspot security password was entered.
Compare the radio and WPSD frequency, colour code, slot and simplex/duplex direction. Confirm the radio is using your assigned DMR ID and low power.
Give each simultaneously connected hotspot or application a different two-digit ESSID from 01 to 99 so the same DMR ID is not presented as the same endpoint.
Do not guess large offsets. Follow the modem supplier or WPSD calibration guidance, change RXOffset or TXOffset in small steps and retest.
Use WPSD's supported configuration fields. Applying the main configuration can rebuild DMRGateway, so restore a known-good profile instead of relying on undocumented edits.
A normal home router does not usually need port forwarding, but guest, hotel or workplace networks can block the outbound traffic a DMR master requires.
You can explore the dashboard without transmitting, but an assigned DMR ID and the appropriate amateur radio licence are required before using amateur DMR networks on air.
No. The current RSGB band plan also identifies 438.8000 MHz and lists 438.7750 or 438.7875 MHz as alternatives. Use a permitted, locally clear channel and make the radio match it exactly.
Normally no. WPSD starts the connection out to the selected network. If a restricted network blocks that outbound traffic, opening an inbound port is not the safe fix.
Yes. WPSD uses DMRGateway and network prefixes, but it is much easier to prove one primary network first and add the others individually.
It is a two-digit extension used to distinguish several hotspots or applications sharing the same DMR ID. Use a different ESSID for each device that may be online at the same time.
No. WPSD is a separate project with its own software, manual and support channels. Follow WPSD documentation for a WPSD installation rather than mixing instructions from another dashboard.
Use the official WPSD manual, WPSD project and RSGB 70 cm band plan for current settings. Software, networks and band plans can change.
