GB3SCX now with DFCWi

Ian Lamb <ianlamb@...>
 

Andy,

Thanks for the technical notes etc., listening to GB3SCX/B this evening
the DFCWi sounds like a set of old bag pipes .... out of tune at that!

Good luck with it and I hope it proves useful.

From 1100z today, the 10GHz beacon GB3SCX located on Bell Hill in
Dorset, IO80UU59, carries a new modulation type - DFCWi - to assist
in evaluation of the mode.

The beacon modulation still carries a normal on/off CW ident followed
by 15 seconds of carrier on its GPS locked frequency of 10368.90500
MHz (nominally!). This is then followed by a DFCWi transmission with
tones 400Hz higher than this for a Dot and 400Hz higher for a Dash,
ie "." = 10368.9054 and "-" = 10368.9056. (All subject to +/- 11Hz
error due to DDS resolution issues)

Dual Frequency CW, with a third idle tone, or DFCWi. is described in
more detail at www.scrbg.org/g4jnt and was discussed on this
group a few weeks ago, but is briefly summarised here, again, for any
newcomers...

DFCWi is coded as normal CW, but instead of different length dot and
dash symbols separated by breaks in the carrier to indicate
intersymbol gaps, the dot and dash symbols are made of equal length,
but instead occur at different tone frequencies. The gaps between
the symbols are greatly shortened and replaced by a third tone
frequency rather than a break in transmission. Consequently DFCWi is
a 100% duty cycle transmission mode.

DFCWi is primarily aimed at reception/decoding using a Spectrogram, or
colour waterfall display, but with a bit of practice can be resolved
by ear.

The parameters used on GB3SCX are :
Symbol Interval 0.5 second
Idle period, 10% of symbol = 50ms
Recommended tuning tones :
Idle 600Hz (or 400Hz)
Dot 1000Hz (or 800Hz)
Dash 1200Hz (or 1000Hz)

Both of these tuning-points 'sound' quite pleasent to listen to with
their tonal harmonic relationship, but make no different to their
appearance on a waterfall display.

There are several suitable pieces of display software around, but the
most versatile is Spectrum Lab by DL4YHF
http://freenet-homepage.de/dl4yhf/spectra1.html <http://freenet-homepage.de/dl4yhf/spectra1.html> .
This can be quite complex to drive, and there are a host (nay,
quintillions) of settings. A good starting point is :

11025Hz sampling rate
1024 FFT
50% overlap (this makes the display move faster and CW symbols look better)
Black/White palette (that's my prefernce, anyway!)
Horizontal scrolling (unless you want to get a cricked neck)

The 0.5 second symbol length is optimised for an FFT of 5 - 10Hz bin
size, so should give teh ability to decode at a few dB below what is
copyable by ear. Part of this experiemnt is to see if these
parameters are suitable for microwave use such as whether longer
symbols lengths might help, optimum tone spacing, etc.

A sample plot from the new beacon received and plotted with Spectrum
Lab will appear on the website within the next hour or so...

Andy,
Did you see the attachment I sent you in reply to your notice of changes to GB3SCX/B?
I am not sure if Yahoo strips off attachment to the reflector or not as I dont see my
posting on the UK reflector here.
I also sent it to your other email address and it bounced, I see you have a different
one now hi.

Just downloaded the latest Spectran - its great for decoding this. Wish I hadn't forgotton this prog!
 Much easier to get going then Spectrum lab and gives a nice horizontal trace, whose speed/resolution can be altered on-the-fly.
 
I've added a picture of the GB3SCX DFCWi decoded using Spectran to the web page.

Agreed, except that uW contests (or Activity Periods - whatever you want to call them!) do take a bit more effort than sitting at home in the "armchair" - as you well know! Having said that, I know what the ravages of time do to one's inclination and, indeed, ability to go onto some high, windy and cold mountain top....so yes, I can sympathise!
 
Agreed also about CW, although I must admit to not being a great fan of the mode - too cumbersome c/f other modes. I regret not improving my CW skills, but then senility made an early onset! It is, of course the way to weak signal working, although I had a very instructive evening, this evening, setting up a 10G NB rx and Spectran (at the local club) and taking GB3XGH (over a very locally obstructed path) with troposcatter and aircraft scatter for about three hours.... that I really enjoyed! Now that is the ultimate in weak signal reception....
 
It's a good thing that we have such diversity of skills and the freedom of the amateur licence to follow our individual inclinations. One of these days I'll get some antennas up and go "all band" again!

Hello Andy,
I have been wondering about that today, as I was checking the

additional trace to the left of the data stream. Included is a picture

Re: GB3XGH now operational

Martyn G3UKV
 

Thanks David for a v. useful 3cm bcn.
Audible 95% of the time here (IO82RR57), with very wide variations in strength - from barely detectable to S7 in past fortnight. these variations don't really seem to match up with what I would expect. eg windy, unsettled weather - S5-7 all day long (Sept. 10th), but faded out in evening. Generally benefits from any hint of rain scatter. Distance about 100 Km.
The reflected sig. (via Wrekin) which I got better than direct path from your home QTH has now disappeared - but studying the path suggests there may be a small obstruction at your end towards the Wrekin now compared to your home QTH.
BTW- the ID gives location as IO73WO, which I reckon is somewhere just off N Ireland. Suspect the "7" should be an "8" !
 
Thanks for your efforts.
 
BTW2: Listened very carefully for 24GHz bcn from Brown Clee (IO82QL), but not heard, even when Peter (G3PHO) gave the right frequency that day. (Sept. 9) Just a bit too far I guess.

Hi Mike,
In answer to your questions:-

Power is ERP 20W as before.
The antenna has been improved - not for overall gain but for a reduction
in the variations in the horizontal plane and for a better pattern in
the vertical plane. Plots will be on the website as soon as I get time.
A write up on the antenna construction will follow.

Location is 4.5Km E from my address, that is about 1.5 Km south south
east of Rochdale town hall. approx SD900120 The beacon is located on a
factory roof at a height of about 9m above ground level. Ground level
there is around 140m ASL. This is slightly lower than my QTH but the
hieght of the antenna means that the immediate terrain is much better
with a clear view out to the Pennines and much improved with respect to
the North. There is also an adjacent 150 ft mill chimney which could
provide some useful reflections. Certainly at my QTH it doesn't
matter where you point the antenna - it gets the beacon - using a bare
dual mode horn 2.5 NF preamp with no dish. It even receives it when
pointing vertically upwards - indicating either appalling
construction/screening on my part or probably reflections from the roof
construction.

Re: dish building

Chris Ruddy MM0KOS
 

Hi all

Thanks again for the replies, the dish would be used for EME and
its not just for me, there is a group of us with a good mixture of
bands and knowledge on HF, VHF, SHF all the way to laser. The main
reason for asking was to get the up and down side of others
experience in building or having bigger dishes, now i can see or
best think, the best way to go is a stressed mesh dish but this
depends on the location we choose for /p work and how exposed it is
to the WX in GM. We intend to use it from 23cm upwards to 10ghz for
EME but we also have beams for 23cm for tropo use, maybe at a later
date we will consider higher bands.
I am just about capable of 23cm EME if I get my finger out and
complete the 2x GI7B amplifier, build the dish i have here and mount
the allready built septum on it.
I have also looked at patch feeds for multi band purposes and have
build one for 23cm but dont know how successful it will be, i need
to get a spectrum analyser on it and have a fiddle to see if it will
perform, if not ill try again and then try other bands on it too.
With regards to scatter point i would be more than happy to write a
small piece for you on how we get on with the project but may be a
little time before we get fully going and hope to have some sort of
web page on line soon with pages showing the current projects that
we are working on justnow

Thanks Gordon and all the others again 73 have a nice September
weekend

Hi Chris--I was interested in the thread on dishes and the various
replies you received as I hope to try EME sometime---hopefully next
year. I also have been wondering whether to build, buy a kit, look
for
a surplus dish or buy a petalised TVRO dish. A lot depends on the
following.

1. The frequency or frequencies you intend to use.

2. Is the dish mainly for tropo or EME.

If you are mainly interested in the lower bands---23 & 13cms then
4m
is a good size. However a dish this size made from GRP would be
quite
an undertaking compared with more common stressed dish made from
alloy. A solid dish this size would be subject to some very strong
forces even in light winds. Reading your post I got the impression
(might be wrong) that your intended use is for a tropo system. If
this
is the case you might be interested in using a plane parabaloid fed
with a twin double quad feed. If this sounds gobledigook look up an
article by G4CYA, Chris Otley. I had some input to this design
though
Chris built the working unit and wrote up his work on his website.
If
your intended use is tropo this antenna has a number of advantages:
ease of contruction and wider horizontal beamwidth. Look at the
article--it should be easy to scale for 4m and could easily be made
sectional for transport.

If you are mainly interested in the higher bands things are more
of a
problem as the profile of the dish becomes more important. Upto
6cms a
dish with fine mesh would seem a good bet. Along with the info you
have already been supplied with, check out SAMI Dishes. This
company
do a very nice 3m dish for around $700 (£350) though shipping and
import might double the cost. ( Still cheaper than 3m RF Hamdesign
I
seem to remember). I'm not aware of a UK supplier of similar
dishes.

At 10ghz or above 1.8 and 2.4m sectional dishes are available--best
price currently around £140 (2.4m) from a company in N. Shields.
Most
commercial dishes have f/d ratios around .4 making them suitable
for
EME---making your own dish would give you freedom to design the
f/d to
match other feeds.

Good luck with your project--whichever route you choose. Please
write
something up for Scatterpoint when you have an operational unit and
let us all know about it. 73s and best wishes Gordon G0EWN

As over the last few days my rotator has mysteriously started working, albeit

Heard it a last week on 1296.890 John.
I believe a DL spotted it as GB3IOJ (!) thereabouts at the weekend.
