This is the next video of the bonus series where we want to build a ground station for the geostationary QO-1100 satellite and contact a station in Antarctica. I will not repeat the content of the previous video. Sot it is highly recommended to watch it first if not already done.
But first I have to thank you: I asked if I should continue with the series. And you responded: The video got four times the amount of comments than my other videos. And most were positive or even enthusiastic. So let’s continue with the Bonus series.

This episode brings back so many many MANY memories. In 2006 I was introduced to our company's satellite ground station. I don't remember all the specs we operated "new" I.P. MPLS across multiple birds. But we were using unused Ka / Ku bands and channels between 13 and 40 GHz. I honestly cannot remember what the broadcast power was. The teleport's 15 meter parabolic reflector dish had this huge fence around it with massive warning signs not to stand within 20 meters from any 90° position of its aimed direction, a bird in geosynchronous orbit at 36,000 km if memory serves. It required some power.. I just cannot remember!! Btw, there is an excellent 2012 Antarctic Satellite white papers online for those that wish to read them.

THANK YOU for showing and using a torque wrench on your SMA connectors! On addition to the "real" metal kind you showed (that cost around $200 US new), there are some composite plastic ones selling for around 30 US that do a decent job. Observe minimum radius rules on microwave cables. Also, look for an HP 11693A Limiter to protect the front end of your spectrum analyzer; they show up on eBay every so often.

@@AndreasSpiess I am using the TXCO modified LNB from qro.cz, it works really well, the frequency stability is very good. I had tried others too which I had lying around, unmodified, they all worked but of course frequency drift was abysmal ! 40cm is a small dish indeed but it works, I have the CW beacon at S5-6. Yesterday I installed an oval 50/60cm dish (horizontal oval), which is giving me an extra + 1 S on the scale. My coax feed line from the shack to the dish is quite short though, only about 3 meters.

@alexandern8671
@alexandern8671 4 года назад
Another great video Andreas, thank you. I just wanted to add a bit regarding the SSB. With the conventional amplitude modulation AM we transmit the carrier (tone) and the modulation signal's spectrum on both sides of it with the amplitude of 50% of the carrier for 100% modulation (i.e. when the modulated wave goes down to zero). If we assume that we modulate with a sine wave, the power, transmitted in each sideband, is only a quarter of that of the carrier. The SSB cuts off on the carrier's power (as you can see on the displayed spectrum, not completely in practice), and on the other sideband. Overall it becomes 6 times more power efficient in this scenario (sinewave modulation). Power saving when idle simply comes from the absence of the modulation signal.

Re: Receiving signals from geostationary satellites. I have a little tiny Pioneer Inno handheld receiver for XM satellite radio, the size of a Walkman, and it can receive signals directly from geostationary orbit. Signals which are hundreds of channels of lovely stereo music, or BBC WS. I can bring it outside anywhere in North America, and listen to satellite radio. I still find that amazing. Cheers.
@AndreasSpiess
@AndreasSpiess 4 года назад
I assume those satellites work with higher power. So it is easier to receive them.
@JxH
@JxH 4 года назад
Much easier. The handheld receiver's antenna is inside a little plastic cylinder just 1 cm diameter by 2 cm high. On the other hand, the bandwidth of reception is presumably about MHz wide to accommodate so high a data rate to provide each boquet of channels. I have to keep reminding myself that the XM satellites are in geostationary orbit, so far away.

Excellent choice! Aquarius people are very easy-going ;-) My math teacher would use this case to calculate the probability out of 200'000 subscribers...

@@AndreasSpiess it depends on the point of view, from my view this is interesting to know. Anyway you showed a cheap rf power meter which reminds me of my Monaco RF spectrum analyzer which goes from 20MHz up to 2.4GHz ish and some bands at 5.8GHz. Have you heard of this product or can you tell something about it? Im wondering if its a real tool and capable to measure real power or more a gadget because at this moment i cant tell and don't know how to find out without a reference.

A lot of people don't fully understand that SSB is AM. What most people call AM is actually DSB with carrier. Interesting here in VK standard and advanced licenses get to play in this 13cm band without special licenses from ACMA. Advanced get a full 120w constant or 400w PEP. Of course our friends in USA get 1500 PEP if they get that band. That's way more power than you'd realisticly need especially when running lots of gain on the antenna. For any non hams reading this the most important thing is line of sight. This is why NASA still hears Voyager 1 and 2 and big dishes and modern DSP. They're 18+ hours away at the speed of light. They don't run a lot of RF power considering how far away they are. So RF power is not all it's cracked up to be. Can't wait to hear your QSO.

Something to point out here, these generations of amplifiers (they're all made by a single company, main chinese amp) did NOT have support for wifi modulation and bandwidths, they were straight dirty PAs. Now you can buy specifically crafted ones supporting 802.11 modulations, as well as bluetooth modulations.

Awesome. Thanks for sharing. I have a spectrum analyzer but it's only good to 1GHz so it's nice to know there's an inexpensive way to measure power. I don't think I have an SWR meter that will work up there either. Maybe I can find one in AliExpress.

Great video! At 4:00 it should say 1mW = 0dBmW But I know a lot of people just write dBm. As an Engineer I think it looks wrong to leave out the Watt.
@AndreasSpiess

You are right. One core belief on this channel is: it's easier to confuse someone than to educate someone. So I must leave out a lot...

I have never seen dBmW in literature or anywhere else. It's not wrong if it's a convention to unambiguously use it that way.
@JohnTarbox
@JohnTarbox 4 года назад
Thanks again for this excellent series! One thing that is known to the experienced hams but which may be overlooked by new players is that one must take into account cable and connector losses, particularly at frequencies this high. I assume you have at least three cables and six SMA connectors between the Pluto and the antenna given that you are using two amplifiers. Wouldn't this cause a loss of at least 3-6 dB?
@AndreasSpiess
@AndreasSpiess 4 года назад
Probably 2-3 dB or so. I use very short cables. But I have a 20 dB amplifier and theoretically only need 6 dB. So no issue.
