Creating a low bitrate wireless data network running over VHF using the UV-5R and potentially a Raspberry Pi to provide remote internet access potentially to a base station at the university.

Proposed plan
* Linux tun/tap diver to create IP interface
* find/create a Mac layer protocol for use on the VHF bands
* Create an encoder to encode the MAC layer packet into audio signals that can be sent over the radio.

Extension ideas
* Routing protocol for out of range nodes/to have multiple base stations
* Pi Backpack that connects to UV5R and provides a wifi access point / network node.

SUWS Antenna Array

2024-01-19T15:27:53Z

Drn: Added new project for Amateur Radio focussed installation to replace SOWN Zepler

{{Project
|Title=SUWS Antenna Array
|Status=New
}}
[[SOWN Zepler]] has been up for quite some time. Its Wi-Fi aspects have never really been used initial due to the pure state of the antennas and more recently due to pervasive high-bandwidth data access provided by 4G/5G. Therefore, replacing this with a fully Amateur Radio focused installation make more sense.

This new installation be deployed on the roof of Zepler but we may be able to find a better location. So for now let us just call it the '''SUWS Antenna Array''' (not to be confused with the [[SUSU Antenna Array]], which never happened).

Equipment Servicing

2023-12-23T16:34:33Z

Drn: /* Tasks */

== Tasks ==

* Replace connectors on inverter.
** Currently has binding posts.
** Suggestion of replacing with banana plus.

* New banners with correct domain (i.e. suws.org.uk) on them.

* Replace PL259 cable.
* Replace opperating paperwork
** Tyler has generated these.
** David will get these from Tyler and laminate in January 2024.

* Obtain adapters for VNA.

* Build power cable for Tuner/Load.
** 8v regulator needed.
** Tyler have a cable he found with the paperwork which may have been intended for this.

* Repair IC7000 microphone.

* Repair FT920 audio cuttoff dial.
** Has been bashed and is now turning smoothly.

* Create contact sheets for non contest contacts.

* Repair the battery.
** Tyler has what looks to be a damaged battery cable he found with the paperwork.

* Build cable to link sounder to other devices.

== Other Faults ==

* HF/VHF/UHF on IC7000 reports infinite SWR into the 20m EFHW
** EFHW confirmed OK with another radio.

* FT707 appeared to be a bit off frequency, according to Charlie.

This is a first opportunity for new people to get involved, so we will mainly focus on explaining what SOWN does how it works and the software and hardware we use.

'''Meet at north entrance of Building 32 at 3pm. If you are running late contact us on #sown on SUWS' Discord server.'''

== Things for new members ==
'''If you can, bring your own laptop with you.'''
* Tour of the B32 server room SOWN is in.
* Set them up on SOWN's SSO (Authentik).
* Show them round NetBox and how it provides a digital representation of SOWN's presence in B32 and B53 server rooms.
* Show them Icinga and how we monitor the SOWN network.
* Add them to the SOWN organisation on GitHub.
* Explain any other SOWN technologies in which they are interested
* Get then to assist with some of the tasks below.

== Task list ==
* Fix the RAID check on GW-B32. (Hopefully just re-running Ansible playbook).
* Get some VMs migrated/converted from VMS-B32-1 (Wok using KVM/QEMU) to VMS-B53-1 (LXD).
* Test the new USB to dual serial cable needed when we deploy new servers to B53.
* Merge users who have multiple accounts on SSO.
