All
I'm hearing a weak slow beacon or perhaps data type signal on 144.175 MHz, I first heard it on Saturday when I listened briefly but it's still there today. I'm only listening on a simple vertical aerial so I doubt it's something exotic and I haven't the means to decipher it - is this something I should know about or is someone using the talkback frequency?

GB3XGH GB3MAN Beacons freq drift

David Wrigley <zen130696@...>
 

The GB3XHS antenna was for a few days tilted and the 10GHz signal would have been seriously attenuated. This has now been fixed but what was not noticed immediately was that a cable connector pulled out of the Palisade GPS receiver.

This means that the ZAZ GPS system is in holdover and all three beacons will currently be subject to a frequency offset of up to 100Hz or so. Hopefully weather permitting this problem will be fixed in a day or so.

Raymond,

If you are likely to have South take-off I would like to try from IO92. Do you have CW?

Hi all,



I will be in Scotland Tay Forest (Pitlochry) this week, if I can get up to any of the summits (weather permitting) is there any interest in 23cm contacts, only 8W and stacked twin-eight array. Sorry for the low power but will be backpacking.

Ray,

I could come on from Edinburgh. I have a good take off north and am LoS to a number of summits in that area. The beacon GB3EDN should be loud as well. My Mob is 07969668147

I'll look out for you, work permitting, if you let the list now approximately what time and day and where you will aim to be operating from.
 
I'll probably only have 10W myself, so CW might be the best option.
 
Good luck - Dave (G0DJA)

I look forward to hearing you on 23cm, Raymond.

Fine weather at the moment.

It's always a dicey business travelling to the far Eastern Counties Chris!

Re: Aircraft reflection

Richard Ferryman
 

I have looked more closely at my signals from GB3USK and there are weak traces from HF of carrier showing on the waterfall. Thes become stronger as they move LF. I did find a couple that were quite strong and have recently had several periods where the carrier and CW shifted signal were steady and strong with a dead straight trace for up to 5 minutes so obviously tropo. I looked at aircraft activity and the majority of flights on that bearing seem to be outward bound from Heathrow to Europe and beyond.
Just obtained a new 1.2M spun aluminium prime focus dish for 3cm so will be concentrating on that band for a while - when I sort out the feed. It has a focal distance of 457.2mm and an f/D of about .38 so may not be ideal for my octagon LNB but is built like a brick s***t house!

I seem to remember reading that it depends on whether the aircraft is flyning towards you, or away from you, that decides if the signals go from HF to LF or LF to HF. I'll have to dig through the referrence folder and re-read up.

That's why I thought the sinusoidal display in SpectrumLab would be circling airfraft going away and then coming back at me, if you see what I mean?

I too see straight lines next to the main trace. I wondered if that meant the aircraft was flying across my line of view? Or, maybe hovering, as in helicopters?

Here is a link to a trace I've just taken from signals from GB3MHL, signals seem a bit "up" on normal as well. Considering that this is without a preamp.

I have also been observing aircraft reflections. I have been monitoring GB3USK down here in the depths of Dover. Due to the high surrounding chalk I am looking at about 20 degrees elevation. 'USK comes in predominantly via aircraft reflection with odd periods of tropo. Aircraft reflections last up to some 30 seconds with doppler starting on frequency and moving LF by 200Hz to 300Hz before fading out. Sometimes both signals are audible so I get a traight line on the waterfall and the doppler shifted trace simultaneously. I have always been puzzled by the fact that the doppler shift never seems to to go HF of the 'USK frequency.

23cm yagi

Rex MacRae <cathar.gnostic@...>
 

I need to find a design for an adjustable driven element for a long yagi. Lots on the net but I need to get the SWR <1.2:1 on 1296.6 which most just don't do. Folded dipoles and 'T' matches work but are not good enough. The wheel doesn't need re-invented, who knows the best way to make one?
Thank's in advance.

DMC 7GHz link part needed

Hi all,

I'm looking for a gain block from DMC 7GHz microwave link unit, either the TX path buffer, or the RX LNA, if you have one / both in your junk box, please get in touch!

Woe is /P

Christopher Bartram <cbartram@...>
 

I went to IO72sa this afternoon for my first /P outing of the year, and set-up the gear. It was also the first time I'd tried my new dish support, which uses the car roof-rack. That was very successful. After setting the dish azimuth calibration, turning the receiver on produced a readable troposcatter signal from GB3CCX, on-beam and on frequency at 170km. That's the first time I've heard any beacon at the site.

I was becoming excited, but I needn't have been. The antenna relay decided not to switch to transmit ... Perhaps it is trying to tell me something!

I tried a one-way test with GM0USI in IO76. Nil at 450km.

I'll be back, but not this weekend, as the visit to the cold, albeit sunny, hillside seems to have re-awakened some flu-like symptoms which developed after my recent trip to East Anglia.
