Hi Peter,
 
You are correct, of course!  I might join you on 21/28 MHz if finding contacts on 432/1296 MHz proves to be slow (i.e. an absence of planes for reflections and no tropo enhancement).
 
Good luck, and good DX!

I do agree, and I have given some consideration to rejoining, but I

couple of letters for publication in "your comments" or whatever they
call the letters column. I think one got published, the other did not.

One evening I got a call from the membership secretary, asking why I
had not renewed my membership. I explained to her, and since she was
not technically minded, so asked I put the comments in an email and
she would follow it up. So I sent them to her, and she forwared it to
one of the editors, who ignored it. So I followed it up, and after
some time he agreed to discuss the issues next time the technical
committee met. So again I waited, and again no response. Over the
course of 6 months or so, I'd had quite a few emails, but with no
substance. Finally I was told the technical committed had met, agreed
with most of what I had said. But the RSGB did not think it worth
publishing corrections to the articles.

Specific ones I remember, although there were others were.

1) Article about antenna loading, with force in kg. Also other units
were wrong, though I can't recall which. I pointed out it was pretty
basic school physics, which is found on the school curriculum.
Despite agreeing the units in the article were all wrong, no
correction

2) Article about an antennas, where antenna A was better than antenna
B be by X S-points. I pointed out that given the calibration on
S-meters is pretty arbitrary, it is pointless making such statements,
and why not use a calibrated attenuator or similar. I pointed out a
stepped attenuator is quite inexpensive on eBay, and even offered to
calibrate one on a VNA for them. No take up of that offer!

3) Another article about antennas, where one is told to measure the
"directivity" of the antenna by rotating it around, and again using
the S-meter. I pointed out the same problem with the S-meter, but
also this was a measure of front to back ratio, and that directivity
has a very well defined meaning in antenna theory, and it is nothing
to do with F/B ratio.


At the time I used to design antennas for a living, and used to
cringe at the "antennas column", at just how many technical
inaccuracies there were.

Apparently there is a review process of articles, but it does not
seem to be working to me, if forces can be measured in kg. I admit
only someone studying antenna theory is likely to know what
directivity is, but anyone writing an antennas column should know
what F/B ratio is, and know an S-meter is not a sensible tool.

There were many other things, and the errors, coupled with their
reluctance to address my concerns, left me wondering if it was worth
being a member.

I was not expecting every antenna article to be aimed at those who
done their PhDs in antennas (which I did NOT anyway), but I would
have hoped for a more basic understanding that what the antennas
columnist had.

Dave
you have fallen in to the academia trap,
Many hams do not fully understand what a dB really means, there is much
confusion between power and voltage, novices frequently make the
mistake of using 100 log10 Pin/Pout.
But they can think in S units, most of the time , so to give
comparisons in S units between antennas is easily understood.
Nearly all of us using the microwave end of the frequency spectrum are
quite happy working in dBs, but remember there is a difference between
the imperial dB and the metric dB.
With antennas its only when you get high in frequency or you start
looking seriously at EME , that you will start to chase fractions of a
dB.
Also if you put an errata page in Radcom it would fill very quickly.
You might as well rejoin and have a monthly dose of frustration, the
microwave columns not to bad to read.
And I still think you can get tax relief on membership, I think HRC
still accept the RSGB as a professional body, which you can claim
against tax, on PAYE they always use to increase my tax code for that.

No, sorry I will not. In fact, I'm no longer an RSGB member - I go so

Postage and packing using Royal Mail "Signed For" 2nd class is £4.20

that is fine. The postcode here is CM3 6DT.

I needed some caps for N plugs, N sockets and SMA male plugs for my 3,
6 and 18 GHz VNA calibration kits.

I found it almost impossible to get these in the right sizes, so
ended up ordering a large quantity to get the size I needed, so if
anyone wants them, I have some to spare. These are good for protecting
things like adapters, attenuators, VNA calibration kit components,
power sensors, RF connectors on test instruments etc.

50 x PVC cap for N male or APC7 = £ 8 (GBP)
50 x PVC cap for N socket = £ 8 (GBP)
50 x PVC cap for SMA plug = £6 (GBP)

The largest size, for the male N plug, will stretch a bit to fit onto
NMD connectors, although one would really want to buy larger plugs if
one had a lot of NMD connectors. But I do use them on my VNA test port
cables when not in use. They will also keep out that dereaded HP foam
when it degrades.

All plus posting and packing from the UK.

I don't have them for SMA female sockets, since 6.3 mm / 1/4" are more
readily available on eBay, so there was no need for me to buy
thousands of the things.

Re: IO91RF in Low Microwave Bands 6-Oct

Hi,

 

This weekend also sees the 432 MHz to 248 GHz event and on Saturday the 1,296 and 2,320 MHz trophy events.

 

G3OHM/P will be on from IO92GB running 400w on both bands for the Trophy period only, so like a number of other stations will have no operation during Sunday.

 

Seems a pity that it looks like we will not be having a QSO with G1EHF/P.  I guess the overall result is spread the activity, so better  for the 24 hour event but not so good for those operating in the Trophy and low band events.  

 

Regards

 

Ian

To confirm our details:

 

G1EHF, G4SJH, G3TCT, G3TCU, G3WBQ will be active as G1EHF/P from IO91RF on Sunday with:

 

23 cm = 250W to 4 x 35 element @ 9 m

13 cm = 60W to 90 cm dish @ 5 m

9 cm = 10W to 70 cm dish @ 7 m

 

We will also have 144MHz talk-back and ON4KST (separate sign-ons for 23 cm and 13 + 9 cm)

 

Hope to work you all!

 

Dave, G1EHF

The group of us who often activate IO91RF in the Low Microwave Bands sessions will be on next Sunday.
(G1EHF, G4SJH, G3TCT, G3TCU, G3WBQ) we'll post the details asap.
We couldn't make the June session as we nearly all had other commitments.

There will have to be lots of good Dx QSOs to justify the early start!

Seriously:

I am increasingly more and more alarmed at

the numbers who indicate that they are to be

active for the contests.

 

Investment apart, the time I put to these events

is increasingly becoming counter productive.

 

I know there are a few who choose not to indicate

their intentions via this reflector, but one cannot

deny that numbers are dropping off.

 

I am active every day. sickness and Christmas day

being the only exceptions.  I know that is my choice but

'Surely',  when you see the numbers active on the

reflector,  some of you could boost the

activity,  even if its only for an hour or two.

 

Like it or not, I still say that if I did not have that

window into France. This station would have been

sold off after 50 years being an active radio amateur,

starting as VQ8BY in 1963 while in Mauritius with the R.N.

to buy a Leica M9 and get a life.

 

Please, please switch on your gear, maybe you may

even enjoy it. Also answer the often debated topic on here

of   "Activity on the bands"., simple!.

Clarke masts

Hi Mike one of my friends still has a mast I believe, but I have 3 telescopic legs that will form a tripod the was used with a 50ft (or there abouts) version. I dont have the collar that goes round the mast, because that was used to mount it on the rear of a trailervan. I am open to offers if you or anyone else is interested.

...its possibly too late to consider replacing the wife. The pneumatic masts are very good, as are Tennamasts. I would not worry too much about the seals. It took a few years for ours to fail and they can be replaced. Something that will go up to over 20m with a lowered length of about 3m is very nice. With just the bottom sections, you probably won't need to guy it and it will still be a useful height.

Hi Frank
 
Unfortunately, as there is also a garage in the way the only way it could go was through the bush!

I had that problem -my greenhouse was in the way. So Tennamast made me a custom mounting so that it did not go over at right angles to the wall but at about 30 degrees!

Hi Gary, Mike
 
Many thanks for the helpful comments. I understand from talking to the rep at Newark that they do not recommend liquid silicone as this causes the seals to deteriorate.
 
OK on the price, I did consider a Tennamast which would be cheaper, but to luff it would require the removal of a rather nice ornamental bush which my wife was not too happy about!

I have three clarke mast's...
two are portable/vehicle mount and work great, as mentions ONLY use silcone as lubricant I find the spray/liquid better but they do say use grease.

the only mast I bought (SCAM12) for my new QTH to set up a home microwave station fails to pump up, this was bought as a working item!
the air seems to be leaking from the 3rd section so I need to sort that before I can mount it on the workshop.

Clarke are very good at responding to e-mails and have even sent me service docs for the SCAM (digital format)
at this moment in time I find there prices a little hard to swallow (Yorkshire man HI)

As mentioned before in breezy and or with heavier payloads they do need guying.
