QO-100

[Julian Macassey]

Are there any lurkers here using QO-100? Terrain
permitting, I'm thinking of giving it a go.

Where are you located? I don't know whether it will be usable from
where your callsign suggests you are.

56 degs North (Dundee), judging from all the dishes I
see screwed on the side of buildings, it looks like I should get
access, trees and nearby buildings permitting.

Ah, so not in W6- (or even N6-) land. I had no idea that you were in
the UK.

It tells me that you are in GM-land, but I can't find any information
on where exactly.

Yes, but I was after a position to <0.05mm

Only on receive on 10 GHz . I've an SG-Labs transverter and a 20W
amplifier I use on 13cm but not got round to trying it on QO-100.The
SG-Labs transverter can be programmed to work on the up link. SG Labs
sell a 20W amp for QO-100, but mine is the 2320 version, but it will
work up there with reduced output.

I used an 80cm dish, but you can hear it just pointing an LNB. I
modified an LNB to feed in an external 25MHz LO. IF was a funcube dongle
.

There's a time of day when the sun is at the correct azimuth for dish
alignment to see if buildings get in the way.

I'm thinking of the Bullseye LNB for my 10 GHz downlink.

I've an SG-Labs transverter and a 20W
amplifier I use on 13cm but not got round to trying it on QO-100.The
SG-Labs transverter can be programmed to work on the up link.

I'm leaning towards an SDR for feeding the LNB, which I
can also use for general SWL use.

SG Labs

AMSAT have a 5W amp. I am planning on being about 2
Meters from the dish, so keeping all the RF parts besides the
LNB and uplink antenna inside the flat and warm and dry.

I used an 80cm dish, but you can hear it just pointing an LNB. I
modified an LNB to feed in an external 25MHz LO. IF was a funcube dongle

From what I read, a dish about 1 Meter would be ideal
and not so big that questions would be asked.

Scratching the back of an envelope, it looks all looks
very affordable.

There's a time of day when the sun is at the correct azimuth for dish
alignment to see if buildings get in the way.

Good to know. How do I find out how to do that?

Https://eshail.batc.org.uk/point/

Put in your location and get the azimuth angle.

Mine is Azimuth: 143.8° (145.3° magnetic)

Elevation: 21.5°

https://gml.noaa.gov/grad/solcalc/

Then adjust the time at your location so that the solar azimuth is the
same.

Mine is 11.12 British Summer Time for today.

If you are really clever, you can get a date and time when the sun and
the satellite are in the same position. This occurs in Spring and
Autumn,

10.49 BST on 12th October,

I'm sure I found a site where it was a lot simpler to work out. It
needs a reverse solar time/azimuth calculator

The Great Repeater in the sky.

Bleep-dah-di-dah

I think it was listening to the traffic on it that put me off going
further . I'm a sort of "try anything once" guy. I was the same with
Oscar 7 - a couple of QSOs and that was it. Some day I'll try EME.

Is Oscar 7 still alive? IIRC It was heard a few years ago in sunlight
because the batteries had gone o/c.
