Also if anyone is intending on getting involved in EME we would love to hear about it! You could even write a short article to go on this website.

There is a wealth of knowledge within the club so just come along and ask!

My venture into 4 meters

On the 11th of march I bought a Simoco SRM9000 from Mike G4CDF. (Thanks Mike!) I finally had a 4 meter rig and he also let me borrow a 4m loop to get me started until I could make my own. I was pretty much working to get it all setup as soon as I arrived back home.

First question when putting any amateur station together is of course how on earth will this all go together and where can I put it?!

The antenna itself is not small and would not be the kind of thing I can just hang in my window. It also has a pole fixed to it for mounting vertically with a horizontal spacer between it and a mast. This made things more difficult as it could therefore not just be laid down on a first floor roof ridge which is close enough to my shack. Instead I settled for persuading my parents to let me stick my military fibreglass mast up on the corner of the house. Amazingly, it blends in quite well and just looks like a piece of guttering down-pipe that is rather small…. Oh and it also has a large chuck of metal hanging off to one side!!

So I have an antenna sorted and a mast for the antenna to go on. I setup the radio connected to the power supply that I have running my other radios on the desk and it immediately sprang to life. Great… I have a radio, an antenna, a microphone and speaker and power. I knew I was missing something.

Aaaaah…. Coax!!!

Next problem – how to get coax into the shack without drilling holes in the wall or doing anything else that seems to annoy my parents! So here is my solution:

It got a little cold last night because the window is now open just a crack for the coax to come through so i enlisted the ever useful duct tape method!!

Finally I was ready to get a QSO on 4m so I then experimented with all the buttons and I think I hit scan and heard Alison G8ROG doing a test. I quickly replied and sort of knew that I would manage to contact her given we are just across the valley from each other. Perfect 5/9 signal!!!

I was given various pieces of advice including about the local nets and events throughout the week and frequencies (Thanks Alison!!)

The important ones to remember are:

  • 70.425 – Local net frequency
  • Nets are on Tuesday evening’s at 20:30 and most members are from RADARC but it is not exclusive.
  • GB2RS news is also read out on a Sunday morning with a net on the same frequency afterwards.
  • Vertical Polarisation is the norm but some use horizontal

So my next steps now are to re-program the radio and have a browse through the settings and of course join in the nets regularly.

If you are interested in getting into 4 meters then there is a wealth of knowledge within the club. Just come along to one of our meetings and ask! We will be happy to help!

There are also some great resources for the Simoco SRM9000 series of radios on the Simoco post linked here

Listen out for me on the weekly nets and I look forward to speaking to you!

RADARC AGM 2016

The RADARC Annual General Meeting was held at Woodford park on Thursday the 8th of December. A great evening was had by all and was kicked off by Simon M0ZSU, and we started with a Chairman’s report. Overall the club has had its challenges over the last year however we have managed thanks to the brilliant help from volunteers from the rest of the membership.

We have a thriving membership of 87 members and we have been growing steadily.

Over the last year, a team of volunteers from the membership have formed a new group that was to take over the organisation of meetings. This worked out well even with the shift of Simon to being Chairman after the unfortunate loss of our previous Chairman, Pete Milton, G8FRC.

We also now have a new website setup by James 2E0JPM which will bring us new functionality and options for the future.

Our plans for a club shack are also still on the table and we are looking to re-start this project soon.

We plan to have much more variety and new styles of talks/evenings in the coming year and hope that we can develop the club to entice new members, young and old.

The New committee was confirmed with a vote by membership lead by Nick Challcombe. All of the committee have been “sworn in” for another year. The new (and old) committee were thanked with a large round of applause from the membership.

Overall, we as a committee would like to say thank you to the membership for their support and understanding over the past year. It has been a struggle but we have coped well. We look forward to the next year, 2017, and hopefully we can grow the club and the hobby.

Join us throughout 2017 for new and exciting talks!

At the end of the AGM we had the Trophy and award presentations and finally Cheese and wine!

Below are some photos from the evening:

Reading Hackspace

Reading Hackspace Visit

On Wednesday the 23rd of November a group of members from RADARC headed down to find out more about the Reading Hackspace, known as “rLab”.

Upon arrival at the small industrial area in the centre of Reading, a small unit with nothing more than a door and a couple of windows sits quietly in the otherwise dead industrial area.

It is 8pm and we approach the door to be greeted by a member of rLab. They led us up the stairs and told us that there would be someone around to give us a tour. My first thoughts… WOW…

The first room we came to was the electronics and desk area. People are sat working all around the room on everything from CAD designs and soldering through to Hard disk recovery and coding. We instantly started asking questions and getting to know a little bit about the group.

Once someone became available we were led around the building being shown all of the awesome equipment, tools and machinery they have there. It was one hell of an eye opener to see that this whole community runs off membership donations and kindness. There were lathes, laser cutters, 3D printers and much more.

We then went back upstairs to the electronics/workbench area and “mingled”. There were some people playing around with LED light boards, clocks, Raspberry Pi’s, Arduino’s, Hard disks, coding on (very) old hardware and much more. We got a demo of the laser cutter which was seriously cool too!

All in all it was a very nice evening and we all look forward to getting to know the hackspace community. We hope that they will also come to find out more about RADARC in the near future. As always, everyone is welcome!

Stay tuned for more posts about our events in the future!

To do on wordpress

This is my personal page to remember which things need fixing/changing before this site is finished and ready for use.

  • Contact form email to send to. The email address that the contact form sends to is currently not set or is set as a personal address.
  • fix calendar API problem
  • check settings and confirm correct security settings
  • add users for all main members/committee/admins
    • It is worth developing a policy on usernames for committee members etc so it is obvious who it is.
    • Look into adding members to the system without them having to register.
  • gallery? create one using a plugin or just forward access to a proper gallery at something like gallery.radarc.org or www.radarc.org/photos etc.
  • Sharing settings: social media accounts for the club? im happy to run a twitter account if we want it? this will raise profile of club and allow integration to wordpress to post on twitter when there are new posts.
  • New pictures for committee members for the committee page
  • contact forms for any other aliases we want
  • Sift through all other info on the old website and copy/re-instate on new site
    • simoco page?
    • do we want to move “old news” into an archive? if so… where… how?
    • continue to port all history over
    • For sale page? or just leave that to be posts in the main feed…. (probably best like that)
  • Populate with articles, past and present

Hello world!

Welcome to WordPress.

And… welcome to RADARC.

This is the first ever post on this WordPress and im looking forward to how well this site can be used.

If anyone finds this post in the future, well you’ve found the internet equivalent of a time capsule… a blog post of no use to anyone buried at the bottom of a blogging site…

Anyway, a warm welcome to the RADARC WordPress and i hope you enjoy my stay!
