If nobody comes up with a receiver, try pixmania, I believe they still carry brand new analogue receivers made by Metronic for £28.

 

[dcselec]

I used to receive quite good signals from the local 23cm repeater a couple of miles away from me using my old Echostar SR50 and a homemade Yagi with a homebrew preamp. After the initial interest, I became a little bored with pictures of members' shacks U-zzz

I might try having a go at receiving the digital transmissions from the repeater.

Scroll down on the page to see the live digital transmission.

Only early days yet but I hope to be able
To receive and transmit as I am licenced
will keep updated as things go on just have to
take care with my nest of antenna and dishes
to keep the station commander happy (wife) Hi
Dave
Thanks for all the replys it helps

Hi Llew
Do you have any details of the amp you used
I would like 35db+ gain to get the box going with the antenna
as with no lnb im sure you know they are quite deaf thats the next step then its the antenna have to be home brew very strange price if you try and buy one
Thanks
Satcom1 Thanks for the reply not enough gain there wil
be no lnb connected just an antenna
Thanks
Dave

Hi Dave

I managed to find the preamp I made after rooting at the back of my junk cupboard.

It's a little worse for wear now, having removed it from its box a while ago, breaking the output capacitor in the process. I used striplines etched on a glass fibre board.

I haven't got the original circuit I'm afraid, all I know is that the transistor was a NE21936 bipolar UHF type, the Zener biassing diode at the top 8.2V. The ferrite beads had resisistors inside supplying the voltage to the transistor. Power supply was (I think) 10V.

I've no idea what the gain was of the preamp, all I know is that it was adequate, as I used to be in line of sight of the top of the repeater's mast before apartment blocks obscured the view.

Not really enough info I'm afraid for you to build it, although if needed, I can check the value of the other components if you want.

My antenna was just a lash-up using heavy-guage copper wire for the elements, all pushed through a hard plastic rod for the boom

Thanks Liew
No worries im sure I will find a circuit on the web
I have managed to find antenna design that will be ok
for rx/tx all I need now is a load of time and no work to do
round the house
Thanks Dave

 

[Llew]

OK, yes plenty of maybe more sophisticated designs on the web. Best option is a DIY antenna no doubt, considering the prices quoted for Yagis.

Keep us up to date on how you get on Dave.

Pluged in the box today its not very happy think
the time spent in the garage have not helped
so it should be back to the top reciver wanted but that
only got one reply so might try fle-bay good news
I have the same prop as Liew 3 story block of flats
but got a pump up mast ex-army and a rotator at a brill
price so thats this weekends job to install that if I get
it done will post a pic with a 20 meter dipole on the top
so be able to play radio for a bit

Ok Dave, as we don't have a section dealing specifically with Ham radio, anything related to that subject would probably best be posted here -
