Re: Jupiter GPS boards

Beware, these boards may well not have coped with teh week rollover, and could be outputting a date exactly 1023 weeks ago
That may have a knock-on into leap second compensation, and epheris determination at boot up

Try it and see - the Bell Hill beacons use one, but as it's hardly ever been turned off in nearly 20 years and has battery backup (a 20+ year old NiCd )   perhaps we're just lucky

Jupiter GPS boards

Paul M0EYT
 

Hi all,

I found a seam of Jupiter GPS boards whilst sorting through my junk shed, they are the ones with the 10KHz output, any use to anyone? You can have one (or N) for the cost of postage.

regards,

Paul M0EYT.

Thanks Kevin,
That would be quick to deploy.
Ive also been sent a link to an old Practical Wireless article  on a portable streased dish, which has some ideas.

Ive also found portable lighting for photography that uses a prestressed collapsable dish..

So ive a few ideas.

Looks good and useful on the higher bands. The only problem with kst is that a lot of ops don't log out when qrt, but I don't think it's such a problem on the higher bands.
Good work!

Hello Nick

Design for unfolding portable dish

Nick Gregory G0HIK
 

Ive done a couple of QO100 activations from fell tops now.
Ive used a 60 and a 80cm dish, anything else is just getting silly to backpack with.
I'm wondering if there are any designs for something that unfolds, about 1mtr and made from mesh for lightness and windloading I would think would be ideal.
I recall some satellites use something that unfurls and looks really cool.
But probably it would be a central hub and some canes stressed with a cord around the circumference.
Google seems not to be my friend in this case, microwave dish is not a useful search term ;).

Unfortunate accident

Chris G0FDZ
 

Hi folks

About two weeks ago my recently completed new 122 GHz system was accidentally dragged off the bench onto the floor by myself when walking past it. To say that I am not happy about it is a gross understatement!!

The mechanical damage has now been repaired but the electrical damage means that it is now longer functional on both transmit and receive.

Does anyone have a VK 122 GHz board that they no longer need, as if so I would be interested in buying it at full price (and expenses) to get my system back to an operational state again?

The old board I will try to repair in the autumn/ winter, and if successful will use that as my test source board.

If you are able to help then please contact me off reflector and we can go from there.

Many thanks and regards

Chris G0FDZ

Still trying to find a decent method for doing a more user-friendly chat feature, that presents it in a more familiar way.   It uses WebSockets so it should run fine on a phone in a standard browser, which will be handy for portable use.

I'll share the URL when it is a little further along.

Thanks Andy & Robin..
Seems they are both web based solutions..
I am looking for an app similar  to hamgps,
which live update locations.. even camera view with target search etc..
If no, I will ask my friends to go for Android hi hi :)

Thanks guys

I've found Element14 in Australia has some generic stainless steel ones and I'm finding more now I know what to look for :)

There is a tick-box on the order form of the PCB fab I use (Eurocircuits). For a while they were provided free, but now a 130 um laser cut stainless stencil is around 27 euro for this small board I’m working on (30 x 40 mm). I guess Chinese fabs offer the same for fourpence-ha’penny. There are also single-device stencils intended for development boards where just one device needs a stencil. Farnell do a range, see order code 2542988

I see lots of mentions of stencils, but I've not used them before.

Mind you I've never needed to solder something quite that small/complex as yet so I've not looked into it.

So... where do I get these stencils from ?

thanks
