Ah, this was on UKuWaves, not RSGBTech

As I wrote in a longer email I posted here, I did write to the RSGB about the lack of quality of articles, especially reviews of antenna analyzers in October 2015, but despite some responses from Elaine, nothing was ever published, and the quality of the reviews remains unchanged. 

I had previously (several years ago) written in about the very poor quality of the antenna column. My comments were never published. However, that issue has been dramatically improved by the new author of the antennas column, who I'm pleased to say does have a decent knowledge of antennas.


Saw your image of how you see the online pub - with overlapped text.  There's something very seriously wrong with your PC setup.
Allthough either format may not be favourable to many, I haven't heard anyone else not actually being able to see it properly

As I wrote, I do run an unusual operating system, but I'm not convinced there's anything "very seriously wrong with my PC setup".

I'm running
* Sun Ultra 27 with 4 cores, 8 thread Intel W3580 3.33 GHz Xeon CPU
* 24 GB RAM
* OpenSolaris (2010 edition) - unusual I admit.
* Firefox 29.0.1
* Firefox ePub  plugin.

Whatever the rights and wrong of PDF, it is a format used by a huge number of companies, and just about everyone has a PDF reader. If the RSGB are concerned about copies of PDF files being circulated, they could do something like

1) Put at the bottom a message - Downloaded by G8WRB from IP address 123.456.789.010 on dd/mm/yyyy. Not for redistribution. It would not totally stop redistribution, but people are going to be less likely to distribute a copy electronically to a wide audience.

2) Add a very faint watermark on the page with the call-sign of the person downloading it. displayed.

The IEEE add the IP address and date/time on many downloads.

Dave.

Re: Really easily transportable microwave dish

Thanks Alan and John,
Both ideas could work but will have to check how much room there is in the transport box when I get home. Pretty full already with 2-4-6M gear including antennas.
One idea I have seen was what looked like and umberella with a metalized coating and offset feed.
As I say not sure how good this would be at 3cm but better than nothing.
 
Will do more investigation when home and see if I can come up with a 'KISS' idea that is fairly robust. Anything after October will see 'real' gales so maybe too late in the year already.
 
Martin, GM6VXB

Hi Martin,

I am just back from France where l just used a small 10ghz panel antenna...about 1ft square and very thin...They work pretty well...managed 320km with 1.5w at sea level....would be easy to pack in the top of your box. ..

More a thought but willing to give it a go.
 
I am doing quite a few jobs offshore presently. All in pretty rare squares until
the beginning of October. I have managed to get low band gear transported
in a nice transport box 1X1X0.5 Metre. This is pretty full with radio, HPA, and antennas for three bands.
 
Now I am wondering if there are any easy designs (or built) for a microwave dish
say up to 1 Metre diameter that can be folded up into a transport tube that would fit into the box.
 
My suspicion is that the surface will not be suitable for (say) 10GHz, but if
there any designs about I am will to give it a try.
 
Next problem would be mounting it on a suitable pole in pretty strong winds.

Re: Power Splitters

They seemed too useful to throw away, they came out of 2.4ghz wireless system I took apart as a client has done away with the wireless POS scanners they use in there warehouse and gone over to a new 4G system.
I will add them to the Contest Group Kit as we will be expanding our operations next year.

The spec is not bad, 1.25:1 VSWR is 19 dB ret loss
Over that bandwidth this is quite impressive. Loss figures are OK too
So they look useable as an antenna splitter on 23 and 13cm
I would not recommend any splitter of this type (ie one without a ballast load) as a combiner for power amplifiers.
As a power combiner, this type has no isolation between input ports and that is very important when combining amplifiers.

Seems a perfect task for Andy's portable beacon, small wide beam and will update the location as you move into new squares? Maybe a small amp to boost output ?
