I bought one of these on Aliexpress and it actually works very well for what it is. The menu settings took a bit of time to get used to, but fortunately I wasn't expecting the moon. Had two QRP POTA contacts using 5 watts with good reports on each. Is it like a top-line Icom, Yaesu, Kenwood or even Elecraft? No, it's not - but for what the UHSDR is, it works very well. This will be my portable rig going forward. 73 de WQ1C
I've been toying with getting one of these mcHF clones mainly for the caravan and maybe a bit of pota as I never go out in the field. Audio sounds ok, The cost seems great for what i need. Cheap enough to hide from the XYL.
Thanks
I have a mchf sdr, it was my first hf radio, it work perfectly every time and I've used it on digital modes hitting a vk station from the UK using wsjtx, I've not tested the freeDV myself due to the same reason but maybe one day, anyhow another great video from Tech Minds keep up the good work.

Thanks for the nice comment, appreciated!
I have the icom ic 705 that radio looks great for the money great video a usual 👍
I have the RS918 with stock firmware and it works wonderful, I'm planning to dump the latest onto it and see how it performs.
What is the difference between mchf and rs918?
I built a V6.3 mcHF radio. Love it. Shame that it became a victim of Chinese piracy.
Hi you will know how to configure the radio properly if you’ve built it.. there seems to lack any comprehensive video info guide on setup..
Amazing little rig for only £300 thanks to M0NKA making the design open source. I also run DF80E's firmware on mine which is incredibly feature rich and stable. I've had hundreds of hours of fun experimenting with mine and worked the world on it. Built in USB soundcard/serial port and all the inputs and outputs you'd expect on a modern rig. Oh and it decodes RTTY and CW on the screen. Why anyone would want to spend £1000 more on an IC-7300 is beyond me.
Hello there :) i ordered one of these today, i had a concern about the cw decoder, did you say it has one onbord ? 73 from Norway
I built a 0.6.3, and bought the Amber TRX clone of it also, which i believe uses the same OVI40 board as this one.
Great channel you have got here. I love it 😍
Thank you 🙏
LOVE IT
I really wanted to buy the kit but missed the boat by a week! It is a shame that Chinese pirates managed to shut down this kit manufacturer. Some of us like to build...
I bought one of the clones - only because the mcHF was not available at the time.
The Rx & Tx quality are good - but I found the firmware really flaky - to the extent I've not switched it on in over a year! I'll download the latest firmware & give it another go though.
What settings do I need to change to get both the scope and waterfall to show up at the same time? Stock std radio bought a month back. Thanks
I bougth a derivated from de original MCHF proyect called R928+. The firmware its not the same for this QRP but exist groups and people can work new releases with more features. I have this QRP for three years and the last year and half I been using this rig for Digital QSO (FT8 mainly) its great for me and dont have intention to change for another QRP.

Thanks!
You mentioned this item is based on a Radio Kit. What’s the name of the kit? As my knowledge and skill level slowly creep upward, I’m finally to the point in this hobby, that I want to attempt an SDR transceiver build. Do you know of any websites or storefronts that sell anything like that?? If there’s a kit version of the radio you demoed in this video, point me to it. I’ve bee wanting to build one so bad as to seriously consider cloning and building Analog Devices old PackRF SDR. I’ve found a lot of little soldering practice kits but I want step it up a bit. Any input will be greatly appreciated. Thanks for the videos. Always interesting, informative and fun to watch.
I bought one of these.. love it.. but have not been able to transmit on it. Power & SWR meters do not register a signal.. will the updated firmware change all the presets to optimise the radio? I know it has PA configuration at 5W and FULL but I’ve not got into that yet.
What type of antenna did you use for these tests?
Saludos 🇨🇱
Looks interesting 👍
Hi i got one of these, i got it from Bangood, i dont have touch knobs, does yours have it ? I also dont have the touchscreen? Hmmm... when i got it it had the newest software and therfore i could not transmit on 11 meter, so a friend og mine changed the software to an early version, and now the 11 meter works like a regular cb radio, but i still wonder where my touchscreen is, i dont csre about the knobs, since the buttons does the same job. 73 from Norway.
Does this transmitter also work on the 11m band because I believe I see in the manual that it is not possible to transmit on the citizens' band? Can someone inform me?
I updated my firmware and now the MCHF cannot receive. The radio itself works fine but no signal ... Only carrier noise. What is wrong? Is there any way you can send me a Calibrated file to be uploaded to the radio please!
TX bandwidth? Ex: IC-7300 is limited to 2.9K but not FlexRadio.
2800. Hardcoded
It seems to me that the screen is very similar to the Q900
Screen is much larger on this radio and the user interface is completely different.
@@TechMindsOfficial How would you compare the overall experience and performance between this radio and the Q900? I'm considering purchasing one of them, most likely the Q900 fully kitted. Your review of the radio is very good and I'm looking forward to seeing more videos from you about it! Thanks!
We can't get hold of him? Monka I think that's the makers name. A friend of mine was previously in contact with him. Now he is not responding to his emails. I don't think these clones shut down the kits. I'm not sure what happened to Monka but he has gone silent?. Perhaps he took the jab? Who knows? I just ordered this radio from China. I think the clones may be the only source now from MCHF RS 918. I stand under correction. It'll be my first HF radio. I'm new in the HAM world. ZS6HOF from Gauteng South Africa
Can you adjust the output power on this radio
Yep, it is adjustable.
Not bad for £300. What is the build quality like?
It's actually very good, well, the one I received was. :-) Cheers
Out of the box is the radio ready to use or you have to set manually the operating parameters?
With mine I set the parameters to what I wanted them to be. The menu is a bit extensive, just make note of that.
The develloper of this fantastic radio is M0NKA stolled by a lot of chinese companies ...
I think you mean Stolen..? Anyhow, can't steal something which is open source. Plus, looks like M0NKA is not selling the kits any more.
@@TechMindsOfficial Stolen mea culpa! You are true but it seems only the software was open source! But its an old story now, nevermind! 73
Hi, someone have problem with hot surface in transmission? 73
You still happy with this radio?
I bought one from Bangood and it's useless. I can hear low back ground voices. But it doesn't receive or transmit. On Reddit it says don't expect a refund or replacement. So a word of warning.
How much did you pay for it?
About 1.50 and a packet of peanuts, oh and an E-bike and a tour around Manchester.. (Link in description)
It doesn't take much effort to understand this is stolen design. The software was open but the hardware wasn't. Sleep well. Rewarding the thief and shutting your eyes is no excuse.
Plus the Chinese versions which I have had are really crap.
