GB3TX overhaul

Posted on by James M0ZAH

Today, Tim and removed the repeater hardware and installed a temporary repeater on UHF. This means at this time GB3TX UHF is on the air (430.8125) CTCSS 94.8Hz. This repeater supports NFM, D-Star and Fusion (local only). Hopefully we can get the network working and use the digital modes over the internet.

The other equipment is now home on the bench. I’m integrating a new controller and will perform extensive bench tests before returning to site.

Signal reports for the UHF repeater welcome. It’s running the same power as the original hardware so the signal should be around the same.

Repeater details:
TOT: 4m
HOG: 20m (Please let the repeater transmitter drop at least once every 20 minutes).
Keychunk: 3 seconds
Pip keychunk: 2 seconds
CW: DE GB3TX is sent on first key up.

MX0WVV UHF linking project

Posted on by James M0ZAH

The future is fun! As part of our linking project at Wymondham, we plan to grow into the Norwich too. These repeaters will be linked to GB3TX and consist of UHF base stations. See further down for locations and planned frequencies.

Why?
You will often hear the “we have enough repeaters” comment. While that is true, we plan on providing linking on top of the traditional repeater network. Our aim is to cover as much of Norfolk as possible, creating a local linked network. This brings local users together preventing silofication.

External linking
As always, we allow external linking. However the predominant use is for local repeaters in Norfolk. Repeaters will disconnect idle links and return to their ‘home’ connection.

Donations
We don’t often ask for money, most of our projects have been self funded. However in this case, things are starting to get expensive. Any donations are gratefully received. Please contact Jim M0ZAH via email (qrz.com).

Location, Callsign, O/P Frequency, I/P Frequency, Tone
Thorpe St Andrew MX0WVV 430.900 438.500 94.8
Horsham St Faith  MX0WVV 430.925 438.525 94.8

Easter Saturday 2m FM Low Power Challenge

Posted on by Rik M7GMT

Andy 2E0DIQ is doing his usual fine job of drumming up activity in the area with another event aimed at getting stations of all levels out portable and having fun with radio.

Details as follows:

Easter Saturday 30th March 1200-1400hrs 2m FM Low Power challenge
To operate on no more power than Foundation licence allows (10w currently, 25w when Ofcom allows, should be by Easter)
To set up /P in a place of your choice, to run an antenna of your choice, at a height of your choice. You cannot operate from your home QTH.
The aim, to exchange callsign, signal report, and WAB square with as many others as possible in a 2hr timeframe.

Walkie talkie challenge:
As above, but power not exceeding 5w (ie no plugging radio into an amp). Walkie talkie to walkie talkie contacts – give it try?

The point of the exercise is to create a level playing field for all operators, of all licence levels and to have fun testing and trying out radios and antennas in the field.

Christmas Repeater Crawl 2023

Posted on by Rik M7GMT

Tis the season to be jolly, so what better way to spread the festive cheer than a good old pub repeater crawl!?

The idea is to have a few drinks, visit as many local repeaters as the group can reasonably reach, make some noise on the air, and generally have a bit of a laugh.

We’ll initially be meeting up on GB3NZ at 20:00 on Saturday 23rd December 2023 and working our way around the list below, ending up back on the Team Wave “home” repeater of GB3VW.

Order (subject to change):

  1. GB3NZ
  2. GB3NB
  3. GB3NR
  4. GB7NB
  5. GB7DS
  6. GB3AH
  7. GB3VW

We could also link the digital repeaters together via the Team Wave MEGAREPEATER, so people can come in from whatever box works for them. Looking forward to meeting up with you all, and please let everyone know by sharing this link. Hope you can join us!

GB0WFD – Winter Field Day 2023

Posted on by James M0ZAH

TeamWave will be taking part in the WFD using the call sign GB0WFD.

Below is a message from our Mattermost system.

Thankyou to all of you for your support as at the beginning of the journey with The TeamWave collective. We are happy to announce our first meet up for this year on Sunday the 29th of January. We will be taking part in winter field day as GB0WFD at the NZ and VW site in Wymondham. It is at Standley steel stockholders NR189JD all are welcome but we will be working out of a little shed so please let us know if your interested in coming along.
Within the TeamWave ethos you are encouraged to come along and work the station. Get hands on with us and play some radio. We will be messing around with antennas in the field and there will be tea and coffee provided. If you would like food please bring it along with you. If you would like to come along please let us know in the DXpeditions feed.

If you’d like more information please contact us on our chat system.

Packet Radio SSID and Alias convention

Posted on by Rik M7GMT

SSIDs

SSIDs are used to identify separate services running under the same call sign. For example, you may have a node, a BBS, and a chat server all running on your home packet station. All three can’t operate as exactly the same call, so an SSID is added on the end to differentiate between them.

There isn’t a fixed convention on which services should use which SSID, but as a group, it would be helpful if we had a “standard” we used, just for clarity. It doesn’t really matter what the standard is, as long as we document it, and stick to it.

With that in mind, I would like to propose the following :

  • M7GMT – Your “raw” call sign without an SSID (this implies -0). Your personal terminal. Use when you connect to other systems, are having a chat, etc.
  • M7GMT-1 – BBS (mailbox). This is somewhat of a convention already, with many TNC’s in-built mailbox defaulting to -1.
  • M7GMT-3 – Chat
  • M7GMT-5 – Node

We can use SSIDs 1 to 15, so if there are other services that several stations run (e.g. DX Cluster), we can add a new line here to keep things organised.

Aliases

Aliases are used as a “friendly name” for packet stations, allowing you to connect without having to remember whch SSID you need. For example, my node currently has the alias WYMOND (for Wymondham), so you could connect by typing either connect M7GMT-5 or connect WYMOND.

Aliases can be up to 6 characters, and should be unique on the packet network. The idea is for these to be memorable, so I would be interested in your feedback on the following formats:

  1. WAVExx – WAVE followed by a 2 letter ID. First letter is first letter of city/town/village. Second letter is type: D for digipeater, N for node, B for BBS, and C for chat. Examples:
    • WAVEWD:MB7NAF = Wymondham Digipeater
    • WAVEAN:M7GMT-5 = Attleborough Node
  2. WAVxxx – WAV followed by a 3 letter ID. As option one, but this allows an extra character for station ID, which would help prevent potential clashes as the network grows. Examples:
    • WAVBCC:GB7MSX-3 = Burgh Castle Chat
    • WAVWYD:MB7NAF = WYmondham Digipeater
    • WAVATN:M7GMT-5 = ATtleborough Node
  3. TWxxxx – TW followed by a 4 letter ID. This allows even more flexibility for the station ID, but is perhaps less clear that they are all associated. Examples:
    • TWBUCC:GB7MSX-3 = BUrgh Castle Chat
    • TWWYMD:MB7NAF = WYMondham Digipeater
    • TWATTN:M7GMT-5 = ATTleborough Node

Discuss

Again, what we settle on is less important than sticking to the standard. I would love your feedback on this, other formats to consider, and so on.

Happy packeting!
