Where do I start??

Postby ingstyke » Tue Dec 31, 2019 12:39 pm

Hello, everyone.
I have just found this forum and hope that I can draw on some expertise (and patience) to get me started.
I have always been fascinated by electronics and particularly radio. Having reached my 7th decade I have a little time spare and would like to look into amateur radio.
I have a Yupiteri MVT 7100 scanner which I bought 30+ years ago when I regularly visited air shows all over the country. I no longer go to air shows so have the scanner set up in my workshop and attached to a discone on the roof. I live in a flat, rural area and listen to military aircraft travelling to and from coastal bombing ranges and their large base.
I would now like to start listening to amateur radio and, hopefully, become licensed so that I can transmit.
I am looking at buying a used communications receiver (my budget is my pension, not huge) to improve on my scanner and give me some insight into amateur radio.
I would welcome any advice on how to progress.
I look forward to all replies.
Thank you
ingstyke

Hi there ingstyke,
It has never been easier for a newcomer to find assistance and help and tuition in gaining an amateur radio licence.
The 7100 is an iconic receiver and still very well respected, there isnt much you cannot listen to with it but I take it that you want to perhaps explore HF transmissions.
For as long as I can remember, the short wave listener has been short changed with regards to HF equipment. Receievrs are way overpriced for what they are and hard to shift on.
A better bet is to buy a tranciever, take the mic out and use it as a receiver until you get a licence...which wont take long.

That way you wont have to shift a HF rx to get funds for a tranciever.

Great radios that are quite cheap

Alinco DX-SR8T

Icom IC-718

Icom IC-746 or IC-7400 will give you VHF as well



All of the above are great performers but you will need some funds for antennas and feedline, local amateurs/club will be on hand to help you with that part, of that I am sure.
Seek out a radio club/organisation near you and I and some others on this forum hope to speak with you on the air when you get licenced and set up.

Cheers

Mike

Hi, Mike,
Thank you for your reply. I will look for a local radio club, sure there must be one near me.

I saw in n old post that Javiation used to offer a service to replace the memory capacitor in the Yupiteru MVT7100. I emailed them a while ago but have not had a reply. Do you know of anyone else who does this??

Cheers,

Steve

Hi Steve,
Its not that hard to DIY on the capacitor swap. The bum twitchy thing is getting the case apart without it cracking at its thinnest area near the battery bay and to change out the cap you need an iron with plenty of heat and some solder paste to aid heat transfer and use a quick on ,quick off soldering technique.
The PCB board where the "super capacitor" sits is double sided so if you have an iron that is too cold, fumbling around trying to force it out can cause the tracks to separate and that is a right royal pain in the arse to sort out.

You can see a very similar arrangement and dismantling steps on the earlier Yupi MVT-7000 model in my blog posts here

And a job for Jean, an 80 + yr old female plane spotter from Northants. She goes spotting with her radio 2 or 3 times a week with her grandson in tow !

You will need a 5.5 volt 0.047 farad "super capacitor" (its not a super capacitor but this what they are known as due the low stress placed upon it, typical life is in excess of 10 yrs).

You could buy the component for £3.95 from Knights on ebay and fit it yourself (some youtube guides out there) or see the comments/description in their ebay listing/ advert..they will fit it for you at a cost of just £23, phone to discuss. That seems very reasonable indeed and certainly worth it for such a fantastic radio.



Heres the advert from Knights, looks like a Panasonic part which are fine.

Doug from Knights Electrocom has been around the radio scene for ages, he has a shop out in the sticks of Lincolnshire somewhere.

Hope this helps Steve.

Good luck with finding a club near you, Im sure you will quite easy and well done indeed on setting yourself a target to get on the air in 2020.

Hi Mike,

Once again many thanks for your detailed reply.
I'm not sure I would want to start pulling my scanner apart, but if I do, I won't have far to go for the memory capacitor. I am also "in the sticks of Lincolnshire".
Looking at his website I could probably get everything else I need in the way of coax, connectors etc.

Isn't coincidence a strange thing?!?

Cheers,

Steve

Great Steve,
Doug the proprietor from Knights will point you in the right direction of a club in Lincs that will get you licenced up in a single weekend of not sooner :thumbup:
You will learn a lot regarding station safety in a very short time but once learned you dont forget.
Glad to be of help getting your scanner fixed up and best of all the prospect of a new hobby for 2020.
Doug will be open tomorrow 2nd Jan I imagine.

Mike.
