Who would have thought that taking back control and leaving a single market would have a cost.

Should make the people who voted leave pay the extras for us. That would be fair.

I’ve got a parcel coming from KUHNE ...they dispatched on 15th of January ....it’s sat in Frankfurt with UPS ever since ...UPS web page now says possible delivery in February.

strangely another parcel from Italy via UPS ordered the same day arrived within 5 days .

I could try some R.S. from home on 3cm's if anyone IO83/GD/GI is on.

The idea for the 13cm power change is to attempt to balance out the numbers in each category for 2021. Same objective with the 6cm change.

On 13cm it's to provide more competition for those with just barefoot DB6NT/SG, or transverter plus small amp, to compete with similar in SAR. Leaving the Spectrian and Nokia folks too battle it out in SAO...

- I must reassemble my 13cm bits, to join in!

I’m expecting to be QRV on 13, 9 and 3cms. My planned improvements to the dish for 9cms haven’t happened yet because I’m a wimp !

 

Weather forecast round here for Tuesday evening looks like quite windy and maybe wet.

I'll attempt 3cm and 6cm SSB from home, for the January SHF UKAC.

 

Will have KST, Zello and 144.390MHz SSB.

Not holding out for many QSO's, but we shall see.

 

Hopefully the snow will have melted by then, otherwise assembling all of the portable kit on the back lawn will be somewhat interesting.

 

Hope to work a few of you local to me in IO91 so sub-100km paths, and maybe out to 150km.

Who else plans to be on?

While you are waiting for a key (as am I .. ) feel free to give my badly written alternative a go.


I apologise for the various inadequacies ... I hope to find the enthusiasm to sort of few of them out soon.

I have installed the 9cm kit on the versatower so the 1M dish will be
at 35ft or so.
There's 15W at the masthead, GPSDO locked; I trust that it will not be
as lonely as during the summer (at 5M AGL!)
I regret I have nothing for 13cm but will be on 'KST from the outset
so anyone beaming towards sunny Essex should try to raise me on there
for SSB tests.
TIA

Will be on, wx permitting, 13, and or 9 and or 3cm.

I'll be on 13cm, hopefully a little more stable than previous attempts now I have made a copper box for the transverter with proper feedthroughs, it may be less prone to oscillation.

I have a PA for 6cm coming that I will be trying EME with, but I may try a little terrestrial with it also, but not ready for this month.

Gap Waveguides

Chris Bartram G4DGU
 

Hello Ethan

The problem (for me) with components involving metasurfaces, such as in a a gap waveguide is that they need a different sort of approach to conventional TEM/TM/TE waveguides. Although I'm more-or-less comfortable with conventional waveguide structures, I don't feel competent to give an answer, as my involvement with metasurfaces has been rather cursory.

There is quite a literature on the subject, and it is probably worth starting a search on-line away from the amateur literature. If you can find back issues of the IEEE Microwave Theory and Techniques Society Magazine, you may well be able to find an introductory paper. I think I remember reading rapidly through one a couple of years ago. There are also a several books on metasurfaces - but be prepared for some difficult (at least for me!) maths.

Iin another life, I did have some experience of electroforming. Trom what I remember, copper requires a lot of care, and the careful selection of plating currents to get to a suitably small 'grain' size in the deposited metal. Particularly am mmWave frequencies, this will be very important in getting the lowest losses in an electroformed structure.

I hope these are useful comments.

Hi ,

The 723 regulator is an excellent device and  much better than the 317 regarding noise
