Cmalton:

SUWS uses Internet Relay Chat (IRC) as one of its main mechanisms for communicating with each other outside of meetings and other events.

== Connecting ==
SUWS has two IRC channels
* '''[irc://irc.sown.org.uk/g3kmi #g3kmi]''' on '''irc.ecs.soton.ac.uk'''. [[title::#g3kmi| ]] for Amateur Radio
* '''[irc://irc.sown.org.uk/sown #sown]''' on '''irc.ecs.soton.ac.uk'''. [[title::#sown| ]] for SOWN and wireless networking
There's usually somebody around at most times during the day to talk to in both of these channels.

=== Emergency Backup IRC Server ===
In the event of a serious power or network failure rendering the IRC server inaccessible SUWS have delegated [irc://irc.freenode.net/g3kmi #g3kmi on irc.freenode.net] and [irc://irc.freenode.net/sown #sown on irc.freenode.net] as the backup channels.

==Clients==
There are numerous IRC clients available. Below are some of the clients used by members of SUWS. If none of these suit, [http://www.google.co.uk/search?q=irc+client irc client - Google Search] may be able to find you something better.

* '''Windows:'''
** [http://www.mirc.org mIRC] is one of the most popular GUI clients available.
** [http://www.icechat.net/site/ IceChat] is also another good GUI client.

* '''Linux:'''
** [http://www.irssi.org Irssi] is a powerful shell text based client that can be run in Screen (so you never miss a minute of conversation!)

* '''Mac OS:'''
** [http://colloquy.info/ Colloquy] is an open source GUI client for Mac OS X.

* '''Cross Platform'''
** [http://chatzilla.hacksrus.com/ ChatZilla!] is a good extension to XUL based applications, such as [https://addons.mozilla.org/en-US/firefox/addon/16 FireFox]
** [http://www.xchat.org/ XChat] is a GUI client that can be run on Linux, Windows (for a fee) and Mac OSX as well.
** [http://www.pidgin.im/ Pidgin] is a universal chat client that supports IRC on Windows and Linux platforms
** [http://mibbit.com/ Mibbit] is a web-based client

==Logs==
Logs for #g3kmi are available [http://irc.cmtechserv.co.uk/logs/irc.zepler.net/g3kmi here]. Logs for #sown are available at http://www.sown.org.uk/irc/. More information about SOWN's IRC channel is available [[sown:IRC|here]].

The Intermediate callsign was a bit of an accident - Ofcom's website accepted it, and wouldn't let me change it afterwards....

That said, it describes me well - Paintball-playing nutcase!

UV-5R Programming

2012-11-28T21:07:55Z

Cmalton: /* Programming via the PC */

== Programming by hand ==
[http://www.miklor.com/uv5r/UV5R-ProgMem.html Original article]

That article isn't as clear as it should be.
Here's a quick summary of how to program GB3IW:

# Ensure you are in Frequency Mode
# Ensure you are on the A channel (top half of the display)
# Ensure the Band setting (Opt 33) is set to the correct band, in this case UHF.
# Key the output frequency as follows: 4 3 3 2 2 5
# Ensure Options 10, 11, 12 and 13 are set to Off
# Delete the memory via option 28
# Save the memory via option 27 (MEM-CH)
# Press * (Scan)
# Key the input frequency of the repeater: 4 3 4 8 2 5
# Press Menu
# Select T-CTCS (Opt 13)
# Change the CTCSS to 71.9Hz
# Scroll to MEM-CH
# Press Menu, ensure the channel number is the same as before, press Menu

You have now saved the channel.

== Programming via the PC ==
At the time of writing, CHIRP is capable of programming UV-5Rs - future versions may not be compatible with newer versions of the 5R, or indeed, older versions!
The serial number of the model that this was tested on was: 201204R41345

'''***NOTE: it seems there are new UV-5Rs that DO NOT WORK with CHIRP, and you MAY brick your radio.... You have been warned***'''

First of all, a few points on this:
* Plug the USB cable in before turning the radio on, else you can end up stuck in transmit....
* The 5R needs to be in Memory mode - you can tell if this is the case by small digits on the right of the display telling you which memory you are on. If they aren't there, press VFO/MR once to enter memory mode.
* CHIRP is experimental on the UV-5R - '''Do not''' expect this to work 100% reliably, and if it doesn't work, it may brick your radio.
* I'm assuming you've got CHIRP installed already.
* Make sure you use the latest CHIRP nightly. Latest release is not good enough!

Now onto the instructions
# Fire up CHIRP
# Click "Radio" -> "Download from Radio"
# Choose your serial port for the PL2303 (clone-of) that your OS will have detected, for me it was /dev/ttyUSB1
# Choose Vendor of "Baofeng"
# Choose Model of "UV-5R"
# Click OK
# You will get a warning message - click "Yes"
# The red light will flash on your rig as it downloads the memory map.
# After the download completes, the radio will reset, and a new tab will open in the programmer window.
# Edit the memories by double clicking on them (note that there are 127 memories, but CHIRP will only show 50 by default - extend the range using the values at the top of the programming window if needed.
# When done, save your template, and then choose "Radio" -> "Upload to radio"
# Choose your serial port for the PL2303 (clone-of) that your OS will have detected, for me it was /dev/ttyUSB1
# Choose Vendor of "Baofeng"
# Choose Model of "UV-5R"
# Click OK
# You will get a warning message - click "Yes"
# The green light will flash on your radio as it is programmed.
# Again your radio will reset, and the channels will be programmed.

Once again - at the time of writing '''CHIRP is experimental on the UV-5R''' - your mileage may vary!

[[File:MayFestival2011 desk.jpg|frame|x400px|right|An outdoor Amateur Radio Station ([[G3KMI]]) with a range of transceivers.]]
Amateur Radio is the hobby of using designated Frequency bands to communicate with other licensed Radio Amateurs around the world. This can be for experimentation, training, or just a good chat with someone thousands of miles away! Amateur Radio also provides a service, aiding emergency services with communication networks whenever need arises.

More Information for newcomers to the hobby can be found at the [http://www.rsgb.org/newcomers/ Radio Society of Great Britain].

A great introduction to the 'DIY Magic' of Amateur Radio by the [http://www.arrl.org/ ARRL] can be found on YouTube [http://www.youtube.com/watch?v=vlDwVhx7miQ here].

For information on Amateur Radio Licensing, click [[Amateur_Radio_Licensing|here]].

== Club Activity ==

We are a young club, so we are pursuing anything suggested by our members and trying new ideas whenever we can. Many of our members are freshly licensed so we have yet to try everything!

Operating as our Club Station, [[G3KMI]], we have so far participated in the following:

* HF (mainly 20m)
** SSB DX
** PSK31 DX
** SSTV
* 2m (144 MHz)
** FM Simplex
** DSSTV nets
** [[Repeaters | Local Repeater]] nets

Cmalton: Add basic UV5R info

The UV-5R is a cheap radio produced by Baofeng, and can readily be obtained for £40 from eBay (sinotel had a LOT of stock).

Unfortunately, without a USB cable it is a complete pain to program.
See [[UV-5R Programming]] for details.
