Re: Any GM's in the Glasgow area free for 3cm's R.S. sked tonight?

Neil Smith G4DBN
 

Hi Nick, sorry I wasn't at home to try a test. NBFM works really well with RS for voice, and you can even do very very silly things like running FT8 over NBFM over RS.  Huge fun.

The doppler shift can be either way, and depends on the relative velocity of the hydrometeors. If they are falling straight down with no wind, they are pretty much at constant vertical speed as they have reached terminal velocity very quickly, but it is very interesting to move the dish vertically and horizontally to map out the range of velocities you can see.

If you point at a beacon or other constant transmission, you get a sort of two-dimensional tomograph of the scattering centres of the storm as it moves. This is part of a longer recording of off-axis scatter from GB3FNY. The horizontal banding is where the beacon is sending its ID as FSK.

The full two-hour chart is at http://www.g4dbn.uk/wp-content/uploads/2018/08/gb3fny-rainscatter-20180824T1335.jpg

More info at http://www.g4dbn.uk/?p=868

Where there is varying wind or rotation, things can get very complex. My dish only has about 1.5 degree resolution, but once I get my 3m solid EME dish fully operational, I'm looking forward to a bit more detailed look at scatter.

Many thanks Tony (CBW) for my first RS QSO. 

I was not ready for the 2KHz shift and found your signal from what sounded like the noise raising up to S8/9.
Also surprising was the signal strength did not drop over a large change in aim, maybe as much as 20 to 30 degrees. Possibly showing that the backscatter point was close to me.
I look forward to be able to work Mark and Denis soon..

On the subject of remote metering, I had a water meter fitted a few months ago. I'm sure the fitter said it worked via Bluetooth, but I seem to remember that I had to have mobile phone coverage in my area when I applied for it. Anyway it hasn't caused any RFI problems.

I have just had notification that they want to fit a smart meter to
replace the recently installed standard new one.

Will it bring RFI into my station?

Will any RF I may generate from HF up to microwave bands affect it?

(It seems I can object if I contact them.)

Re: 122 GHz Chips

Paul G8KFW
 

Hi Don

 

We in the UK are making a UK order and the order should be finalised this week end so if you live in the UK  and want to be part of the 122 ghz party

Hear are the facts

 

The fully made up and tested PCB is $204 the bare board is $25 we currently have interest in the UK for 31 Made up PCB  and 6  blank boards 

 

So far the blank boards have been only ordered by people who have ordered 1 or 2 made up PCB’s

 

It is estimated that the delivery will be 6 to 8 weeks  

All the prices were estimated on an order of 10 so prices may reduce, all prices are subject to VAT and import duty at approximately 25%

 

Roger  G8CUB is coordinating  but failing that send me your contact details E mail / address/ phone number  and I will forward them on

 

The additional metal work will be dealt with separately but will require approximately £60 for a dish launcher  or a 21 db horn is also available

The  system will require a receiver  so we will coordinate  and decide on  a UK frequency later but it will be within the 144 to 146 Mhz  

FM TX will be  directly to the PCB

 

The current record for this set up is 50 Km

 

Best Regards Paul     or call 07719 208048

That's great Mark.

My takeoff is very poor and all my 3cm's has been /p except to GI where my take off is pretty good. Hence wanting to try Rainscatter or as you suggest AS.

Someone else mentioned the two Central Scotland Beacons, I had settled on looking for CSB this evening as there were no recent reports of BIG on Beaconspot, so it's good to hear from you that they are both QRV.

2.7w and 60cm dish here BTW.

I'll message you this evening and and maybe Denis can join in :)

Remember Fri 9 August, when 10% of the country was deliberately switched off by automatic load-shedding.
Just think if they could do that by randomly selecting 10% of households in the UK

Joking apart, there are rules in place about that remote cut off ability.   It amounts te the same in law as if they disconnect you 'normally' by coming to the house and removing the service fuse.

(There was a VERY long discussion about smart meters on RSGB-Technical a year or so back, a lot of details were given)

Lies and statistics.......Whilst the wonder new meters will be powered from the Supplier side of the mains, it

would be interesting to know how much they consume from the grid compared with an old style Ferraris disk

meter?

What is quantifiable however is the the power consumed by the display units, at the consumes expense!

Ok, maybe the consumption is only 1 watt in which case the annual consumption will be a shade under 9 KWh

per year, so £1-2 a year per household.

From another angle .....Sept 2018 there were 12.8 million smart meters installed.. every million translates to

an extra MEGAWATT of generation required from the grid!

Lies and Statistics!

I've not noticed anything, but RFI is pretty dire here anyway.

I'll need to look for mine on the bands you mentioned on the funcube
dongle. The Scottish Power site however says:-

"The short range radio signal is similar to wifi and bluetooth, but is
actually a low energy system called Zigbee."


My electric meter is in a metal box, but the RF seems to get out. The
gas one is plastic.

I was disappointed that you can't  access the meter data from the module
even though there's a USB lead. It would have been nice to plot it over
time.  My computer can see the USB port as unrecognised, so it is doing
