Re: GB3LEX operational

Is there no one out there in normal range of GB3LEX on 10 GHz who can check and let microwavers know if GB3LEX is operational or not ???

What's the (uW) world coming to . . . .

Received an e-mail from Leicster group as follows:
"Our Engineering Manager, M1NAS, has been on site today looking at LEX. It looks as though there may have been a possible low voltage from the psu in the bunker which possibly resulted in the beacon up the mast not receiving enough voltage. Once that fault was cleared the correct frequency around 108MHz was being generated and hopefully is making its way to the masthead box. 

We have no 10GHz rx capability at the moment as Geoff, G3TQF, our beacon man is in the midst of a house move."

As my 10GHz dish is not up today, can anyone provide an answer to Geoff G4AFJ's above request ?

Jt65 centres of activity VHF and UHF.

Recently someone asked me where the JT65 mode activity is on 23cms terrestrial modes. I couldn't answer and it got me thinking. I had a discussion at the RSGB conference with fellow RadCom columnist,  Richard g4hgi.
We both agreed that it would be good if we had such a frequency on 4 2 70 and 23.
So we decided to push XXX.165 on all bands except 70.165 (there are two eu beacons on that freq) as a "leave your RX on" frequency.
It's in the narrowband MGM allocation of the band plans and 65 makes us think of JT65.

See you on there!

Thanks Paul - that could be very useful.  I'll check their lists.

Good to meet you both at the Convention.

Hi Dave,

Good to meet you at the convention and thanks for the SMD course.  We have dug out an infrared oven and are thinking about a controller.

There is a good range of pipe fittings at bes.co.uk. £40 and over free next day delivery otherwise £4.95.

www.pipestock.com/pvc/pvc-pipe-fittings have a good range of non domestic plumbing stuff.

Hi Mike,

Hi Dave
 
I have several times needed that type of cap for drain pipe and been unable to find it locally, so perhaps you could publish the name of the company.
 
I too have finished working on the PCBs and am doing the metalwork. I found soldering the BNC connectors needed my 100W Weller!
 
Good to see you again.

Thanks Ted.  Really good to see you again on Saturday, and glad that you found the day interesting.  I've been talking to the company that Howard recommended abut the plastic plugs today.  They are sending me some samples, and if I can find a suitable set, I will modify the Manual to include a waste-pipe solution.  The company were very keen to help - I don't think they realised that we are only talking small quantities!

 
Take care,

Good evening Dave,

 
Very many thanks for your lecture and SMD workshop on Saturday - thoroughly enjoyable.  The posting of the E Field Active Antenna pdf on your website was very timely, as I was planning and have now done the ally box panels today.  Next time I go to my local builders merchants I will look at their 32mm waste fittings.  Some years ago I fitted an Elecraft BL2 into such pipe with end caps as well as a homemade slim jim.  Will report back if I have any success.
 
Congratulations on winning the RSGB Construction Competition - hope it helps your business!
 
Many thanks once again and hope you still enjoyed the weekend, despite all the work involved.

Following the talk at the RSGB convention over the weekend I’m trying to track down the RadCom that featured the 5.7GHz project.

 

A search in the “RadCom Serach archive” reveals nothing more recent than May 2015 for the search term “GHz” and a search for “5.7” delivers nil results.

 

Can anyone point me at the appropriate month?

Oops-
Freudian slip

The synth chip,  as anyone can see if you look at the photo,  is an ADF4153;  a conventional Fract-N type with external VCO.   Not ADF4351

Confusing numbering - with two digits interchanged.

ZL2VHX Beacon needs your help - WTD Kuhne beacon TX for 3.4 and 5.7

gm4plm@...
 

with the success of ZL2VHX beacon in New Zealand we desperately need a Kuhne beacon source for 3.4 and 5.7


If you have a spare unit you can part with them please email me as this will allow the VHX site to be easy extended to 2 more bands

this has been a great success on 10 GHz and we want to extend this further -  Kuhne no longer have this in the shop and no longer make them - so if you have a unit you can spare to help out please email me

thanks!

LFA Yagis

ian hope (2E0IJH)
 

Having just finshed some 432mhz yagis with LFA loops, Has anyone tried making a 23cm yagi with a LFA loop as the driven element.
 
My understanding is the LFA loop is a horizontal full wave loop, although this would be small at 23cm, I would guess the sides could be 4mm tube with 3m tube as the loop ends to give you adjustment.
 
I dont know enough about yagis to know if this is either pratical or possible on a 23cm yagi.
 
Just thought I'd ask the question
