Let's submit experiences and opinions of the Q900 SDR transceiver based on hands-on experiences. I have many which I hope to share and receive answers to some of the problems I have had making this rig do what the ads say it can do.

I have seen amazing videos in Chinese and in Russian and in English which show the Q900 at work. Why doesn't mine do that?

Do you have a good manual for the Q900? The oneI downloaded from the manufacturer's website, Version 2.2, leaves much to be desired. Anyone have one in Chinese?

George, W9ZSJ

Ok - been watching all the youtube videos both good and not-so-great.? Found one on ebay from a reputable seller second hand.? Hoping for the best and preparing for the worst.? I'm an avid Xiegu fan, owning and having a lot of fun with my G106, G90, and x6100.? We don't talk about the GSOC in the house anymore as things do tend to get thrown around a bit.?

Like George - looking for a better manual and what support places there are for this radio.? The WhatsApp channel seems to have gone away.

Bob KT8DX

Hi George,?

manual version 2.2 is the latest, I have not found anything else yet...

My experience sofar, is that the website is not really up to date.. I have not seen newer versions of the software although mine was delivered with a later version than on the website..

Thanks for putting the group together.? Question - are ALL Q900's problematic?? I see lots of grim info on YouTube but I also see some videos where people are finding them to be fine.? I just purchased on used on ebay and am hoping for the best.? Thoughts?

Bob KT8DX

The attached PDF contains a number of links to materials on the web which contain real information about the Q900. Many pages I have seen are just quoting ad material. None of those are listed here. Unfortunately, the best videos are not in English. We cold use a good Chinese ham who actually knows English.

You should be able to click on the links to go directly to the site. The links are live.

If you find similar (or better) sites, let us know and the list will grow.

Got my new to me Q900 today.? Initial impressions are that it is solidly built.? All the buttons work.? And I'm able to receive 20 m POTA stations.? I have SW v 3.2.1 in it and the HW is V3.0.? Is this all current as far as we all know??

I am a technical writer by education and wrote professionally for many years. I'm thinking of developing a manual for this thing around "use cases".? In other words, instead of documenting that this button does this and this button does that, I would write sections around "Operating CW on the HF Bands" or "Using local FM Repeaters".? Maybe folks on his board who have been using this radio can suggest a list of topics for the manual sections I'd write.?

Thoughts and ideas are welcome!

Bob that would be BRILLIANT.?

COZ:

Glad to see your videos where you are using a Q900 in comparison with other rigs.?
I hope we (those of us still struggling with the Q900) will be able to get some advice and help from you.

I’ve been digging into throw radio now for several hours. ?The verdict is that with the exception of 160m being around 13 watts out everything else is up to spec. ?The interface takes lots of micro button pushing but the flexibility and filtering are excellent. ?Made several cw contacts last night, and used FLRig to tune around easier. ?Cat control setup is a breeze with flrig, ham radio deluxe, and dxcimmander. ?All in all like the radio a lot. ?

the separate vhf/uhf antenna situation with the dmr module installed is a pain, but since I plan on using this on satellite maybe this will be a blessing.

still learning but very happy with the rig.

bob kt8dx

Great to hear, Bob. And, glad to hear that the usual ham apps work well in your experience. I would recommend that those who have use Fldigi do that soon. Or, install the CNSDR which looks like familiar SW reverse engineered. It is even set up for N1MM.

You have a more recent version of the firmware than I have been wrestling with. I hope I have better experiences when I do that.

I can't seem to get CNSDR to work reliably.? The CAT portion works, but no waterfall or spectrum scope.? Wish it did as it would open up more of the features on the desktop compared with other rig control programs that just partially implement.? Any secrets out there to getting CNSDR to work properly?

If you hit play at the bottom of the app, that starts the waterfall. See if that works.?

When I do that I get an error message "Object reference not set to an instance of an object"

In this menu, you have the choice of DMR and DFM. Can't find any reference anywhere to DFM.? Anyone know what this setting does??

This is how quohetec explains it.?

Have you tried going to the speaker settings and select q900 ?

Thanks, Brian. We need a DMR expert here if one doesn’t have one locally.

George W9ZSJ

Thanks for the reply George.? Does the DMR work in this radio in the US?? I think I read somewhere that it works radio to radio but not radio to repeater.? Can't verify that though.??
