McMichael Rally 2021 – CANCELLED

I am sad to say that once again I have to announce the cancellation of the 2021 McMichael Rally.There are many factors involved, but the main one is the delay in ‘unlocking’ the government announced on Monday, which means the government rules which will be in force at the time of the rally do not allow the event. The committees involved cannot with all conscience continue planning the event for 2021.

The rally is a unique type of event which is both social and commercial, and attracts a large number of people from all over the UK and this number would have been likely to be increased further by the lack of similar events for some time. Safety has to be the foremost consideration.

Myself and the committee are very disappointed as I am sure many of you are, but let’s look forward to next year.

73, Simon M0ZSU, RADARC

Andrew M5ARC SK

Andrew M5ARC became SK on the 17th March 2021 following his illness over the past 12 months.

Andrew and Alice had released a lot of his radio equipment to the club before he had to go into a care home.

Andrew did a lot of contests with Tom G0VQR and Andy M5ALC (SK) and the club in the past.

The funeral will be a private family one and Min G0JMS will pass on any thoughts or memories of Andrew to the family. The club’s thoughts are with the family.

Andy Levy M5ALG SK

We were sad to hear of the passing of Andy Levy M5ALG on December 27th 2020.

Andy was a major factor in the McMichael Rally Committee for over 15 years as Booking and Organising Manager, with his cheerful welcome to all, he was in to contesting being first licenced in 1995 as G7UET.

His other interests were the Christian Aid Walk, Motorcycling and Sea Cadets.

Our thoughts are with his wife Maureen M3AGI and family.

RADARC on Discord

Hope you are all keeping safe and also well hydrated in this heat!

Some members may not know that RADARC is now running a Discord server. Discord is an internet-based chat tool that runs quietly in the background, and is great for those times between meetings that you just remember something you want to discuss, either to someone specific at the club, or as an open discussion. It’s much more lightweight and quick turnaround than email is.

It’s available for Windows, Macs, iPhones and Android phones, is free, and pretty easy to use once you’re up and running. There’s been lots of interesting chat already on lots of different topics, and you can mute what you’re not interested in. The only thing missing is you!

If you’re interested, ping someone on the committee directly for an invite, or email committee @ radarc.org.

Motorola MC Micro Audio Connector

I have designed a 3D printable audio adaptor for the Motorola MC Micro radio. The design cab be downloaded on Thingiverse here :-
https://www.thingiverse.com/thing:4495393

The design consists of 3 parts. The first is a grip which wedges between the internals of a 9 pin d-sub plug and the chassis of the radio. This isn’t strictly necessary but does help to avoid the plug vibrating loose. The internals of different plugs might vary so this grip might not always work but the design is made available in Tinkercad to tweak if required. I tried making a plug which would go all the way around but the minimum thickness of plastic most printers use is 0.4mm and there was insufficient space for this to work.
The second is a plate which holds the phono socket while making it easy to access the nut to do it up tight.
Finally there is a simple spacer piece to stop the end of the phono socket touching the d-sub contacts. This part is 20mm long and can simply be scaled to a different height when printing to compensate for a phono socket which has a much greater or shorter required depth.
All designs can be customised in Tinkercad :-

Parts Required :-
1* 9 pin d-sub plug
2* M3 * 30mm screws
1* phono socket

You will need to remove the metal surround from the d-sub plug. You might be able to snip it away using some cutters but I used a dremel type device with a small cutting disc to chop through it at the top and then peeled it back using a pair of pliers. If you do this please wear safety glasses as these small discs can shatter very easily if they catch and the sharp pieces can go flying off at quite a speed.

Step 1 is to push in the d-sub plug and then push in the grip behind it.

Next take the phono socket and solder wires to it and the solder ring. Make sure you do this before fitting as the heat will very easily melt the plastic.
Fit the phono socket. The plastic tends to deform a little under constant pressure so even with a spring washer it might loosen a bit after a while so I would suggest adding some silicone to fix everything in place and help stop the socket from rotating.

Feed the wires through the spacer and solder them onto the d-sub plug onto the speaker contacts.

Screw everything together and fit a phono plug onto the end of the speaker wires and it’s ready to test.
