Another UKuG contest takes place this coming weekend - the June edition of the Low Band events on 1296MHz, 2300MHz, 2320MHz, and 3400MHz.

Times are 1000 - 1600GMT (1100 - 1700 BST) on Sunday 6th June.

The weather forecast looks set fair for Sunday, and as this contest coincides with a microwave contest in many European countries there should be some good DX available.

As usual I will compile an activity list, which will probably be published Saturday evening, so please post your plans before noon Saturday. Usual format please:

Callsign: G3XDY
Locator: JO02OB
Bands: 1296MHz 400W 4 x 23el
2300/2320MHz 200W 0.8m dish
3400MHz still QRT (replacement transverter awaited)
Talkback: ON4KST & direct CQ on 1296MHz
Times: Various throughout

If the relays are still available, I could make use of them in my BAO 45w amp.

Thank you.

OZ5SHF QRT maintenance

Ole OZ2OE
 

Hi all

The OZ5SHF beacon system will be QRT for service/repair starting from tonight May 31'st. This will affect all beacon signals from 1296 MHz to 24 GHz.

I'll announce here when they are back in the air.

73 Ole OZ2OE


Wanted: WR-102, square flange, to co-ax or WR-112/WG15 transition

G8FXB
 

These seem to be rare but does anyone have a spare WR-102 to SMA, N or TNC transition or a WR-102 to WR-112/WG15 transition, please?
Here are the dimensions of WR-102 https://www.atmmicrowave.com/wp-content/uploads/flg_102cvr.pdf

Thanks,
Graham

Thanks Tony,

I had that one as a backup plan but would prefer one like the original which has
a low-pass filter on board. Looks like Alan has what I need.

Neil,

You can buy one completely built for £7.99 + P&P from the UK:  Ebay 123816843596

Hi all,

Not quite Microwave but the next band down.

My 70cm transverter amplifier has expired (Tant capacitor has burned up, destroying part of the PCB).
Does anyone have a surplus, unbuilt, GM3SEK amplifier PCB lurking in a cupboard?
These are the ones for the larger modules like the RA30H4047. Sam, G4DDK used to supply
them but has none left.

Hi Neil, not a bare pcb, but I do have one that has been built but I am not sure for what band.. If you would like that send me your Postal address off list.

Hi Andy,
Two pcb’s and two programmed PICs
would be ideal.

No, I'm not doing those in that form, at least not directly.
Take a look at appendix A of the AUdio keyer and see if that meets your requirements.
I'm only supplying PCBs with a programmed PIC - not made up or as full kits

go to http://g4jnt.com/BcnKeyer.htm to get your.

All additional components - with the exception of the SOT23 voltage regulator (which isn't essential anyway if you can run it from 2.5 to 5.5V) are available from the Chipbank

Re: 13cm surprise

I still have a some spare relays from the spectrum analyser dismantle last year.
Work up to 18GHz, 28V non-latching coil

£18 each if you're interested.

There's a photo of them all somewhere in the archives of this Group dated ~ June/July last year, but I can't find it

Hi Simon,
In the absence of any other responses, I will answer your question.
Yes, you need a relay to switch the antenna from Rx to Tx. At 2.3GHz it has to be a real coaxial relay designed for the job.
Most people use SMA relays made by Transco, Dow-key, Sage, RLC, Narda etc. All are similar in design and are compact and effective. Though these companies may have merged or changed names over the years, they are still available on the surplus market. Even if many years old they are still  a good bet. I think it is fair to say that very few of us would be looking to buy these new, as the price would probably be horrendous. You could ask here and someone may offer you one at a better price than is sometimes asked on ebay!

Re: 3cm?

Hi Ben, it's a nice sunny day, so doing the washing, making lunch, watering the plants, walking the dogs, taking Caroline out and generally doing Weekend things. Weekend contests are very awkward for me at the moment. Pity that all that lovely ducting last night has fizzled to nothing.  I can't even hear GB3CAM, not a squeak out of PKT or KBQ except a sniff or two of aircraft reflection.

Paths to the south-west are dreadful from here at the moment, I can only just hear myself on Mow Cop WebSDR. Pleased to make it with GI6ATZ/P IO74 and G0HIK/P IO84 over the highest bits of the Pennines.

Huge reflection from Clive GW4MBS in IO71, but only a sniff of tropo, then no more planes. I'll try to get back on later when chores are all done.
