Very well put, Dave - in a nutshell !
Two other quick comments . . . .

A publicised mobile phone number is a really useful 'fall-back' resource    and    
When I changed from a 3G Mi-fi widget to 4G widget, all previous problems with dropouts from /P high spots (like Clee Hill) vanished !

From a cost-per-watt perspective, the MRF13750 at ~$200 and easy availability seems a better option, as the Quorvo device is $800 and hard to get.  Personally, I would think a pair of MRF13750's into a combiner would be a better bet.

Hello Dom,

I agree completely! That's exactly why I prefer a more distributed approach!

I hope to have a QSO with you on 10GHz (and 24!) once I've organised a proper antenna system. That unfortunately has to wait until I've finished renovating my house ...

Just a thought, before you go down the OCXO route, did you see the info JNT posted on the 0.28ppm TCVCXO devices?  Probably just as stable and with a much much lower current draw, which may be an attractive option.

Re: [UKuG-Committee] 24 and 76GHz loan kit plus other stuff

I have the two 122 boards here. So let me know when you want them Neil.
I have a 47G loan system. It is just a mixer, but a fundamental mixer so works reasonably.
I am happy for it to be loaned out. Though I want to keep ownership for now, as I may need to reclaim the multiplier.  My thoughts are, get it loaned out, then look at the feedback, and see what updates can be made.

First thanks to the group for this loan equipment – it does get used regularly for both NB and DATV, the last outings was 10 days ago.

 

Secondly, any potential loaners should be warned that it is no good borrowing it unless you have a QSO partner – I’m very fortunate to live in the centre of activity and so have several potential QSO every time I take it out.

 

Thirdly, I have no idea who the Chiltern Group is and I live as near to the Chiltern Hills as you do to the Norfolk lowlands or the Wash!!!

Just a reminder that the Group has 24 and 76GHz loan equipment available free for member's use as well as 5.7 and 10GHz, the latter are in demand, but there's no one on the waiting list so you could have them within 6 months if you ask.

Please note that you will be expected to arrange collection from the existing loanee for all this kit.

 

As for 24 and 76 It has been suggested that "we" should build another set of equipment for 24 and 76GHz based on the new Kuhne units but so far no one has volunteered to build them. This is sad, as the group has the funds sitting in the bank gathering dust, and I'm confident the group would approve its purchase. So far no ones's come forward with a plan to make it happen, by saying they will put said kit together into a plug and play loan system.

 

The existing 24/76 kit has been out on loan for 3 years with the Chilterns group and they have/are doing great work with it, including ground breaking ATV use, but hopefully they've now had time to decide that they like the bands enough to build their own. (Tongue firmly in cheek here!)

I'd like to see it go (maybe) North if anyone is interested. It would only make sense to do this if either there are two sets of kit for each band, or the loanee already has a potential QSO partner with equipment.

If no one else is interested in borrowing it of course, the group are more than happy for it to remain in the hands of the Chilterns Group as it's getting great use.

 

That aside might we be better to buy a few of the new 122GHz kits from VK land?

Again, if anyone is prepared to build them into a working loan kit please email me and i'll arrange the purchase subject to Committee funding approval.

 

And finally, we as always have funds available for GHz band beacon/repeater hardware/software development, you just need to get the relevant form from the Website and send it to me.

In my time as Treasurer, I don't think we've ever turned down an application that met the criteria!

Re: Mast mounting enclosures?

John Quarmby
 

I use weatherproof (gasket sealed) aluminium diecast boxes for nearly all the masthead kit apart from a recently added 24GHz system. I have ferrites on all incoming DC leads where they enter the boxes to reduce conducted RFI into the box, and all the RF connectors are bulkhead types. I have not had any issues with full legal limit on the bands from 70MHz to 1.3GHz from antennas only a metre or two away from the boxes. If you can tolerate a bit of extra thermal resistance then PA heatsinks can be mounted on the outside of the box without overly compromising the waterproofing, and on my 9cm system the diecast box serves as the only heatsink.

The downside is weight! Plastic boxes are a good deal lighter, particularly in the larger sizes.

Re: Horn antenna

Andy G4JNT
 

A few made from PCB material over the years:
L to R:    3.4GHz around 15dBi,  10GHz 19dBi,  two off 5.76G  17 and 16dBi
Gain figures within a dB.   The larger 5.76GHz one has an interesting 'history'.   I first knocked it up for my work place, originally on 4.(something) GHz and it sat on top of Portsdown Hill gathering signals for a few months.   When it was no longer needed, since it had the same waveguide feed as used for 5.76GHz it was retuned and repurposed for a more civilised task.

Re: A poor evening up Clee Hill

If there is a problem with mobile signals it might be worth putting the phone at the focus of a corner reflector and using it as a hot spot.  The has potential to solve 2 problems.

1. Too many strong signals around
2. Too weak a signal

When I started on 70cm I used a corner reflector made of garden canes and bits of welding rod or similar.  Eventually I saved enough pocket money for a pair of 18ele Parabeams which has tons of gain.

It really helps if you make a big noise on the GHz reflector, Twitter, Facebook, KST etc well in advance and people will be aware you are about.

The days are gone when people leave their rigs on the "calling channel" listening to white noise.  In fact on the GHz bands those days never really existed due to the extreme directivity of antennas, limited range and low activity. Most QSOs have and always will occur via rearranged skeds.

Realistically, with the current level of activity, the only time you'll get a QSO from a random CQ above a GHz will be if
(a) conditions are up, (when people will be looking for activity)
(b) during a contest, or
(c) when people know you're on/ going to be on.

Hope this helps you

Re: A poor evening up Clee Hill

At the weekend we had plenty of activity on .390.  Indeed we had a justified complaint that we were not QSYing and therefore hogging the frequency. Then the 2m Yagi blew down.  We did have a pile up on KST as well as 3 stations calling at the same time on 3cm.  No-one came back to us on Zello.

Thanks for the QSO Neil.

I heard your calls on Zello, but I had visitors last night so was unable to operate at all.

There is certainly a strategy needed to prioritise the long-distance contacts, as in the last couple of contests, I've missed stations around the 300km mark because they were tied up with other bands or contacts, and I should have asked a bit earlier and kept asking.

Using 13cm as a springboard and working up the bands is certainly a good strategy, but with the exception of stations within 150km or so, hearing any off-axis CQs is fairly unlikely even on 13.

I keep a nag-list of the stations I expect to be active who are over 200km away so I can start asking for contest QSOs once they have worked their locals, and also watch the user list on KST.

I've not seen any "only talking to my own group/friends" behaviour on KST, although a couple of stations never respond to my requests, but I suspect that is because they are working flat out on multiple bands and know they have a terrible path to me, so prioritise easier contacts, or perhaps have connection problems.

I keep a close watch on whether messages are coming through late on the web KST, and do a disconnect/reconnect which then gets me back to normal response time and sometimes delivers meeps that were stuck somewhere in a buffer.

Hopefully I'll be around for the next SHF UKAC session. I'm usually available for tests at any time on 3cm unless it is very windy here.  I can do speakymode, on-off beeps or digimodes of most varieties and even DFCW and QRSS for those with extreme patience.  Just not to IO91 because Trees.

I arrived late last night to the KST party after 9pm local, but yes there is a challenge to get the busy folks attention, now that there is so much activity. I'm not complaining about that btw!

SHF UKAC used to be less stations on 13cm, and the other bands were side-shows. Now there is so many more on 13cm, scores on that band are impacted by so many more requests for 9cm and 3cm, and to a lesser extent 6cm KST requests.

The trick is to run 13cm, and use that as a sprinboard to acquire contacts on the higher bands. For that use case 13cm becomes the talkback.

Running 3 or 4-bands, and answering all the meeps politely in sequence, I imagine is nigh on impossible for most stations. I too had mobile connectivity problems (on O2) which meant KST froze or just didin't work at various times.

Well, that did not go quite to plan.  I dragged the 3cm gear out to Clee Hill and got set up, only to discover that I could not get an internet connection on my phone for KST ... quite why I have no idea, maybe I need to try a different provider.

No matter, with 100W of 2m I was confident I would raise someone on 144.390 even with a vertical mobile whip .. but apparently not.  I called for around an hour and then tried .200 and had a brief chat on SSB to a chap in Coventry .. and on FM S20 had a good 57 contact with a chap in Swindon, so I was confident the 2m was working at least ... tried another half hour on .390 and came home, I shall try again .. next time I shall take a selection of mobiles on different providers to find one that does get internet connectivity up Clee Hill!

It was a nice evening anyway :)

Hello Dom,

I agree completely! That's exactly why I prefer a more distributed approach!

I hope to have a QSO with you on 10GHz (and 24!) once I've organised a proper antenna system. That unfortunately has to wait until I've finished renovating my house ...

I too went portable yesterday evening with 6 and 9 cms. But with KST continually disconnecting and no one interested in trying the difficult path to the South-West I gave up just after 9. Most of the activity seemed to be on 13 so will take 13 out next time plus one other band. Only have space for two bands!

Conditions seemed pretty poor with the usual beacons down in strength.

Ah, pity your KST was playing up, my best direction had you seen my plaintive calls, hi.

And I should add that I should (hopefully) if this amplifier arrives from Poland have sufficient power to go portable on 13cm next time, maybe that will help. 100+W from Clee should do nicely!

Hi,

I am aware of the move towards pre-arranged skeds, however until I have some confidence in the equipment, I don't think making a long list of pre-arranged skeds is a good idea.

I had planned to use KST, but as noted, was unable to get a connection to the internet. One of the motivations to me producing the kst2you software was to be able to use KST directly from a phone without needing a laptop, so I do "get it", I just need to find out what network works best up Clee.

I'd be interested to try a few non-contest skeds prior to the next expedition ...

It really helps if you make a big noise on the GHz reflector, Twitter, Facebook, KST etc well in advance and people will be aware you are about.

The days are gone when people leave their rigs on the "calling channel" listening to white noise.  In fact on the GHz bands those days never really existed due to the extreme directivity of antennas, limited range and low activity. Most QSOs have and always will occur via rearranged skeds.

Realistically, with the current level of activity, the only time you'll get a QSO from a random CQ above a GHz will be if
(a) conditions are up, (when people will be looking for activity)
(b) during a contest, or
(c) when people know you're on/ going to be on.

Hope this helps you
