Hi Dave,

I think you make a very good point, in respect we have technical support in the form of RF/electronics side of things
but you are very much on your own when it comes to hardware unless you are lucky enough to know the right people of pay for items to be fabricated.

On the flip side with this diverse hobby there will be a broad skill set and varied interest from one person to the next so maybe teaming up with others and doing a "skills exchange"

As for the tilt question I think you asking for the angle for an off-set dish? in which case it all depends of the size/brand and so on of the dish... for example is it a old BSB dish or maybe a newer type oval "sky digital" dish? there is no standard answer?
a table of known dish off-sets may be of help here on the UK microwave group site.

Finally given your situation why don't you scale back on the antenna front on a more forgiving configuration to get you on the air,
I think the best options for this might be a prime focus dish to get round the off-set angle OR a large horn which will reduce wind loading and be easier to aim.
You could even consider mounting in the loft if you have enough room? no wind loading/weather proofing to worry about or for around £60 (when I bought mine) a slotted waveguide with around 9dBi gain.

I am happy to give you a hand with ideas and fabrication a solution and may even have a suitable dish or point you in the right direction for the horn.

Can we adopt a more positive note on this stream. It seems to have been hi-jacked into into back-biting and complaining!!  I thought that a new beacon in the outer reaches would be good! ;-)

Remember it is only a hobby - not a way of life!

I think I will go back to receive only on this and become a SWL again!

I'll be taking a few of my 23cm driver kits (see www.g4bao.com) to Friedrichshafen. I'll be there for the whole event.

If anyone wants one, either find me in the "throng," call me on site on 439.100 77Hz CTCSS or leave your contact details at the RSGB stand or with anyone wearing a "Camb-Hams" shirt  and I'll find you.

Sadly I'll be in Friedrichshafen all the time you'll be QRV as will two other potential 10GHz QSOs to JO02!
Shame, as I still need GD on 3cm. Hope you have a good weekend!

Some of the camb-hams should have /p hf and sats over there so I'll tell them keep a look out on 40m for you and sats if you're taking such

GB3MHZ signals

Dave <dave@...>
 


Now that the GB3MHZ signals has, from my view of it, settled down again and the new frequency stability has been implemented, I now think that I know how far off frequency my 23cm system is...
 
If I take it that you should receive a signal from GB3MHZ at an audio offset of 600Hz in CW mode, then setting my receiver so that the beacon signal is centered on 600Hz in an audio display seems like a good idea.

So, if I set the incoming audio, in CW mode, on my Kenwood TS2000X when monitoring the GB3MHZ beacon signal, then any difference in what I see on my dial to what the beacon should be transmitting on, is an error in my receiver.  Unless the beacon transmitted signal frequency is wrong, of course, but let's not go there.
 
Currently, and for a long while now, the beacon is steady at 600Hz audio frequency, in CW mode, and my dial frequency is 1296.831.43 MHz.  So my receiver, and I suspect my transmitter, on 23cm is about 830Hz high of the 'correct' frequency.  So, my system is at least 1.4kHz (600Hz plus 830Hz) away from where I think that it should be.

Any Ideas?

Dave <dave@...>
 


OK, here's a project that I'd like to throw out for input...

I have a DB6NT 10GHz to 432MHz G3 transverter system which is capable of 5 Watts output but, currently, only has the normal MKU-G3 input (I might consider investing in a preamp, if funds allow) which is sitting here doing nothing at the moment.
 
I did package it up into a box, with changeover relays and delay switches, but could never get my head arround the mechanical problems...
 
The electricals I can cope with, it's the mechanicals that I struggle with.  Like, how to mount a dish on a pole above a rotator, or on a tripod.  In the WBFM days a short length of waveguide and a penny feed seemed to work well, but now I'm trying to find lengths of low loss semi-rigid and then trying to mount the feed horn, which was made for me and I gratefully use, onto some arm in front of a dish and then tilt it down at an angle that I can't remember to make it work.  And then mount the whole contraption on top of a tripod, or even worse, on a pole above a rotator.
 
For me, it's these bits of nformation, advice and help that seem to be lacking from the talks, demonstrations and information packs.  The one on the RSGB Microwave beginners project was OK, but when I tried it on a slightly windy hill, it swung about all over the place and was uncontrollable.
 
So, what I think I'm asking for is a bit more mechanical engineering input please. What angle do you need to tilt things for horizontal beaming, how do you mount heavy things so that they don't fall down in the 1st strong breeze and mechanically what sorts of hardware do I need to look out for, or persuade my partner and/or local authority that I really do need?

There have been a number of new beacons in the past few years,
personal and otherwise where groups have bothered to make the effort,
notably in GM and the North.

So the only excuse anyone has for not having a beacon in their area
is lack of people prepared to make the effort put one together, find
a site and get it licensed.

Don't wait for someone else to do it for you ....

Whilst the ex-GB3CEM beacon hardware sounds like a good idea, in

by G4BAO. No one had suggested any other real use for the HW at
the time of Russ' passing and GB3PKT was in great need. A few
impractical and ill-thought-out ideas had been briefly mentioned
but no one stepped forward to take on the their suggested
projects. Now the beacon sends its signal out east across the
North Sea and west across the UK towards Wolverhampton from a
really nice location and although we couldn't get the callsign
changed to Russ' it does send his name in the CW steam. Right now
it is a good signal on rain scatter and has been heard across
much of the UK on its west antenna lobe.

Hi Brian,
 
Hearing your beacon GM3WOJ for the first time today, basically a weaker version of what your audio feed demonstrates, same scattered type signal, but really weak 41s at best, in and out.

Hi Nick,

Interested in your thoughts on it. I have noticed that the signal picks up in the evenings as it is getting dark.
The wx is pretty settled at present and it will be interesting to see what happens when we get some good going rain! In my experience it rains most of the time on those high peaks!
I will leave the audio streaming, but I need to find some more energy efficient way of doing it as it involves running a PC and my FT736 plus 3cm transverter.

Plan A was to stream IQ data from a dongle/PLL LNB and raspberry pi but the upload speed on my internet couldn't handle it. I need to look further into that.
