Thanks for the reply Ken. If anyone has a couple of suitable relays or knows of a source please let me know.

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!

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.

HI Dave 
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

Nice North Sea duct on 3cm

Neil Smith G4DBN
 

I am beaming west at the chimney of Drax power station. Reflected off that I am hearing OZ5SHF, DB0VC, DB0GHZ, PI7RTD, PI7ALK at better strengths than direct, and also hearing GB3PKT, GB3LEX, GB3FNY and GB3CAM. All on the same waterfall....

Very useful facility, that chimney, just about omni.  I suspect there is an elevated duct and I am getting a better way in vias the chimney than beaming direct.

DB0VC is 763 km, OZ5UHF is 730 km, and DB0GHZ is a ridiculous 599 at 578 km.

It will all evaporate by tomorrow of course. I might be able to get on for a couple of hours, but no promises, so I won't make a formal activity post for the contest.

I take it you'll be up the top of Sleive Croob?

I'm not LOS from this side at IO74MT or MU, but could set up at
Portpatrick IO74KU61 or Port Logan IO74MR54. I could get over for about
11am local.

Now if you could drum up a couple of other GIs ...

Re: G4HUP PIC Board

Andy G4JNT
 

You might as well dump it, Mike.   If it's just a sequencer, and the device is so obsolete the usual PIC programmers , (the PICKIT family) won't even handle that one.
I have a matchbox of several 18F84 devices kept for "legacy" reasons, but they're never going to be used now.

I hope to  test my bare homemade 10GHz transverter, so only 200mW.
Apart from some experiments 45 years ago with 2K25 and gunndiodes, this will be my first real 10GHz entrance and hopefully first QSO...........
