Nearby APRS
Fixed position ยท APRS
offNo GPS in the radio? Give it a fixed position: Kelly sends it over P25 to the P25X Reflector, which beacons it to APRS (aprs.fi) and the network map as your Callsign-SSID. "Internet" sends it straight to APRS-IS through the Kelly bridge instead.
Locate a radio
via the P25X gatewayKelly asks the P25X gateway to poll the radio's GPS -- a Tait SDM location poll for a Tait radio, LRRP for a Motorola APX -- and the fix lands on this map. Auto goes by what the network has heard the radio as; it needs to have keyed up on a repeater recently. A Tait answers only when its location format is Tait SDM.

records ยท trophies ยท missions ยท club leaderboard๐ P25 bridge
Kelly joins your LoRa node (Meshtastic, MeshCore or LoRa APRS) and your P25 radio. Bridged texts are plaintext and carry your callsign, so they ID. A [P25 text never goes back to P25 and a MESH text never goes back to the mesh.
โ ๏ธ Direct mode only sees the texts this radio receives. It can't see radio emergencies, status messages or site alarms on the P25X network. Only the gateway's Tools > Mesh alert bridge sees those, so a rule for emergency, status or alarm does nothing here.
Rules (the same JSON as the gateway's Tools > Mesh alert bridge)
Addressing: on the mesh, @VK4SIR hello goes to that ham's P25 radio. On P25, @mesh @VK4GJW hello goes to that ham's mesh node, and @re thanks answers the mesh station that last reached you.
๐ง Packet paths & golden packets
Hearing a station far away is one-way. A golden packet is the other half: a packet you sent that reached it, proven by its answer. Hover a station on the map for every hop its packets took (โฌ heard via, โฌ route to it, ๐ฅ two-way).
๐ช Golden Packet token
One signed packet the club passes station to station. Each hand-off is a DM your node signs, so a token belongs to a radio, not a browser; the P25X gateway keeps the ledger and refuses a second hand-off of the same token.
๐ Contacts
Your node keeps its own contact list. Share a contact one hop over the air, swap contacts as meshcore:// links (the MeshCore phone app reads them too), remove one, or rename your node.
๐ Mesh trends
What your node has heard over time, kept by the bridge (--mesh-history): signal, traffic, airtime, battery and how often DMs get through. Pick a station to see its own history. Hover a chart for the value at that time.
๐ก Repeater management
Look after a MeshCore repeater over the air, through your own node: log in with its admin password, then read its battery, noise floor, airtime and the stations it hears, or run its commands. A wrong password gets no answer at all, so a failed login takes about 16 seconds.
๐ Rooms
A MeshCore room server is the mesh's notice board. Log in (its guest password, or blank to read only), and it sends you the posts you haven't had, one at a time. Your post goes to everyone in the room.
๐ป Channels
Your node's channels. Public and #hashtag channels are open to anyone; a ๐ private channel's QR code is its key. Add one from a QR, a picture, a pasted link or a #name: Kelly shows it first and adds nothing until you press Add.
๐ง Set up a node over USB

โ๏ธ No node? Ask the gateway (Meshtastic)

P25X radio aliases
โRadioID.net issues one DMR ID per callsign, but you may run several radios. On P25X each extra radio swaps the leading 5 of your 505 DMR ID for a radio number 1-4 or 6-9: 5051568 โ 1051568 (TP9400), 2051568 (Motorola). Kelly looks an alias up under its DMR ID for the callsign and name, and keeps each radio's own ID everywhere else. MMDVM / BrandMeister don't do this -- switch the rule off on those networks.

P25X code plugs
โThe status and preset-message lists every P25X radio is programmed with -- the same lists as the P25X dashboard's Code Plugs page. Statuses and presets go over the air as numbers only, so a number must mean the same thing on every radio. The TM9100 holds 16 of each (its hard maximum); the TM9400 holds hundreds, built around the TM9100's: the same first 16, then extended. Copy (TSV) grabs a table tab-separated (header + rows) to paste straight into a spreadsheet or the programming application's grid.
TM9100 programming
idleRead or program the code plug of the TM9100 Kelly is connected to -- no Tait programming application needed. Each time, Kelly asks you to power-cycle the radio: switch it off and on again with the cable still plugged in, and Kelly catches it as it starts up. A read takes about two minutes, programming about one. Afterwards the radio restarts by itself and Kelly reconnects.
Read a radio
Reads the whole code plug and saves it as a Tait .m91p file -- a backup, or a ready-made setup to program into other TM9100s.
Program a radio
Pick a .m91p file Kelly saved from a radio. Files saved by the Tait programming application are in a different layout -- program those with the programming application. This overwrites the radio's whole code plug.

| Service | Downlink | Uplink | Tone | Notes |
|---|---|---|---|---|
| Voice (crew contacts, ARISS schools) | 145.800 MHz FM | 144.490 MHz (Regions 2 & 3, incl. Australia); 145.200 (Region 1) | none | Split -- the crew listen on the uplink |
| SSTV events | 145.800 MHz FM | -- | -- | Usually PD120 / PD180; announced on ariss.org |
| APRS digipeater | 145.825 MHz | 145.825 MHz (simplex) | none | 1200 baud AFSK packet |
| Cross-band FM repeater (when active) | 437.800 MHz FM | 145.990 MHz FM | 67.0 Hz CTCSS on the uplink | Doppler on the 70 cm downlink is about ยฑ10 kHz |
The uplink tone for the cross-band repeater is 67.0 Hz, not 88.5 Hz, and the 145.800 voice downlink has no tone. Listening needs no licence; transmitting to any ISS uplink needs an amateur licence -- and this page never transmits.
Doppler and why the steps matter
The ISS moves at about 7.66 km/s. As it comes towards you the radio waves bunch up and 145.800 arrives a few kHz high; overhead the shift passes through zero; going away it arrives a few kHz low. Received frequency = 145.800 MHz ร (1 โ range rate / speed of light).
The ISS transmits wide FM (about ยฑ5 kHz deviation, a 25 kHz-style signal). On a wide (25 kHz) channel a 3.4 kHz offset is mostly tolerable; on a narrow (12.5 kHz) channel the signal is already wider than the filter and a few kHz of offset pushes it off one edge -- loud distortion and dropouts. Stepping 2.5 kHz (the bank) keeps you within ยฑ1.25 kHz of centre; CCR's 500 Hz or 1 kHz steps keep you within a few hundred Hz. Your radio rounds to its own synthesiser step, so check that it supports 2.5 kHz channel steps on 2 m.
Band plan: the Australian 2 m band uses 25 kHz channel spacing for FM simplex and repeaters, with 12.5 kHz narrowband channels in between; satellite frequencies 145.800-146.000 MHz are kept clear for space use.
Programming table -- 5-channel Doppler bank
| Channel | RX | Offset | When | RX tone | Bandwidth | Mode |
|---|
Program these as receive-only analogue channels (TX inhibit) in the radio's programming application. Since the real shift tops out near ยฑ3.4 kHz, CH1 and CH5 (ยฑ5 kHz) mostly catch the first and last seconds of a low pass.
Setup guide
- Position: set Kelly's fixed position (GPS page) or let the radio's GPS fix it; or use the browser location / type it in on the Radio Automation tab.
- Elements: press Fresh elements once with a radio connected -- the P25X gateway fetches the ISS TLE from CelesTrak (about 170 bytes over the air). Kelly refreshes it at most once a day.
- Radio link: connect the radio over serial (Admin โบ Serial) or the IP bridge, in Command or Transparent home.
- CCR mode (best): needs a VHF Tait with CCR enabled in its programming (Tait Radio API). Kelly enters CCR at AOS, selects analogue FM, wide bandwidth, opens the squelch and tunes the receive frequency in Hz -- then leaves CCR at LOS (the radio reboots) and goes back to your channel.
- Channel bank: program the five channels above, set the zone and first channel here. Kelly opens the squelch with the monitor function and steps channels as the Doppler moves.
- Test: tick Dry run, press Bench test pass and read the command log. Then untick Dry run and run it again with the radio on the desk. Then arm it.
๐ DNP3 Demo
A substation, its DNP3 outstation (RTU) and a SCADA master, all in this page. Switch plant on the Substation tab, control it over DNP3 from the SCADA Master tab, and read every frame byte by byte in the Packet Inspector. Run it all in this page, or put the DNP3 on air: this Kelly as the outstation (RTU) with the NUC or another Kelly as the master, or the other way round.
NUC as the master: on the dashboard's DNP3 MASTER page set the site IP to this radio's repeater, the outstation address to the one above and the master address to match. Its breaker TRIP / CLOSE switch F1 here.
Every frame goes up to the P25X gateway, which passes it down to the outstation's radio. Another Kelly as the outstation needs the gateway's DNP3 forwarder.

idleNew versions of Kelly Page come from the P25X gateway over P25 packet data -- no internet needed. A release is about 500 kB: roughly 20-25 minutes of repeater time, sent in pieces of about 2 minutes with gaps so others can talk. Choose Quiet hours to fetch it between 10 pm and 6 am: leave Kelly running and connected, and it picks up where it left off -- even after a reload.
Install writes the update straight into your Kelly Page folder -- the first time, pick that folder (the one with index.html in it); after that it's one click. Every file is checked before anything is written, and Kelly reloads when it's done.
