Many thanks to all responsible for an excellent day. My first round table which I thoroughly enjoyed will definitely return next year for the weekend. Looking forward to finishing my kit and getting out and about.

The damsons were exceptionally nice, quite a special flavour. Sitting in the nice warm lecture hall, tucked up in my coat, with a full load of damson crumble and custard, I'm afraid I slept through part of Neils "secret squirrel" lecture, despite my best efforts to stay awake!

Hi Guys I agree 100% with Daves Comments ,Great Venue , Great Food and Company . Interesting Lectures and a very good Antenna Test Range . 73 Bernie G4HWA On Mon, Dec 5, 2022 at 10:05 AM davidm0ghz via groups.io <m0ghz.david=dsl.pipex.com@groups.io> wrote: A big thank you to John & Nicky and Paul & Heather for organising this great event.

My thanks too to the organisers, presenters, testers and the cooks :-) That was a VERY tasty Cottage Pie and genuine Shropshire damsons in the crumble too :-)
An excellent day out that I'll plan to extend next year. The Antenna test range answered several questions, not least 'Offset dish angle web calculators' can be wrong...... I also picked up some excellent bits from the free tables - thanks to the donors generosity, they will live on.... Gareth |

Many thanks to everyone who helped organise all aspects of yesterday, a very productive day for me in many respects.

The noise source is an HP356C K01, ie normal drive. It has a 2.4mm connector, but will bring adaptor to 2.92mm.

Yes please Roger – I would like an idea of how my 18 GHz noise source performs at 24 GHz.
I take it that it is 28v drive?
Thanks

With Noise figure being measured at the RT. I can bring a 1-50G source, if anyone wants to measure 24 or 47G? Even higher up to 110G if there is demand?

I may drag a 24G (ish) antenna and my 10G antenna down .. I don't really have a mount made up for 24G, but it has a bracket ...kinda.

Will anyone have a wavelab set up so we could plug in and test our modules ? As this is quite a hot project ATM. John G8IKP

Bring it along. The doors open at 09:00. We can
be there quite late. Bring a PSU.

No problem. The 5W 18GHz attenuator should be
near enough to give an indication. Sometimes the attenuation is
slightly reduced at higher frequencies. I don't know what others
find. We might be able to calibrate it.

HP 8485DHi Paul, It's SMA connection and power could be as much as 2W. Don't worry if you haven't the neccessary attenuators to make a measurement, it would have been useful to check but not essential. 73 David M0GHZ |

Hi David,

What connector will you be using at that frequency and what power level will you be expecting? I have an HP 8485D power head and a 33340C 20db attenuator. The power sensor is 100pW to 10 uw i.e max -20dBm. and has 3.5 mm connectors. We may need more attenuators but my others only go up to 18GHz at 5W. I have assumed that you want coaxial and not waveguide. I would have to rummage through my waveguide bits. 73 Paul G8AQA On 27/11/2022 14:06, davidm0ghz via
