I love this guys voice. It’s very soothing
I just surfed in and discovered your excellent channel. Well done. You have a gift for taking the complex and simplifying so that a little mind like mine ( joke ) can understand it. I look forward to your other videos. Cheers.
Thank you Arthur!
I'd love to see a comparison of the Lime SDR and the mini Lime SDR specs to some of the new SDR based receivers/transceivers.
Me too
I pride myself on my technical mindedness but every time I see a new SDR device online I feel like I'm drowning in alphabet soup. Thank you for this. Time to dust off the call-sign, put up an antenna and see what's out there.
Didn't quite understand 50% of what you presented but got enough to be intrigued. It wasn't your fault - just my ignorance of receiver/transceiver technology. A good, appropriately detailed video - thanks!
A great introduction, I'm going to look to see what other videos you have made about this superb sounding bit of kit. Thanks for your work!
I always figured that SDR is the future for Ham radio. Awesome video. Thanks.
You’re welcome! I would love to try a Flex radio, they look awesome, but very expensive!
@@TechMindsOfficial The direct sampling of Flex systems would be amazing as well..$$$
@@TechMindsOfficial Couldn't you build something similar with Lime SDR ? How would the specs compare ?
Did you say 30Mhz of bandwidth? Can we see a demo of receiving the entire FM radio band at once in a waterfall display? For example, can the LimeSDR Mini see this entire range at once? 87.5-108.0Mhz
did you find out, yet?
That would be cool to see
Enjoyed the video. I also use the lime SDR with the Portsdown and look forward to further videos on this. Many thanks.
It's a sweet piece of software. I am using it in my PhD and it's a blast. Best bang for the buck.
@@joeboxter3635 Lime Micro. You can get'em at crowd supply website. I must say it is an intermediate-range SDR, thus requiring a bit more work than a USRP N210/B210, HackRF or PlutoSDR. But for the price, you can really adapt existing tutorials to fully grasp it.
@@joeboxter3635 All are transceivers, but limeSDRs and USRPs are even capable of running a limited LTE eNB. It is not an easy task to accomplish, but there are plenty of videos about it. Cheers!!!
What is your PhD in? Total nerd speaking here
Thanks for the video. Please don't forget that before transmitting you have check the signal quality in terms of harmonic suppression and IMD. 73 de R2AUK
Amazing video. I just realized i should be a patreon. Keep up the great work.
Thanks Ali!
Thanks Matt, very useful!
Thanks just want I need. Something else to spend money on.
No it's something you WANT not NEED lol
Back ordered every place I can find it.
Couple of years late - but hey....good video
Thanks 😇 Better late than never haha. This is an introduction for some more videos on this :)
Thank you for the interesting video. It would be good to add a comparison (pros and cons) between LimeSDR Mini vs ADALM Pluto including the spectrum in the transmission mode on 2400 Mhz and an opportunity of using an external reference frequency other than 30.72 MHz. 73 de Karen, ra3apw
I searched for "use an sdr as a vhf repeater", the first result was your video, I wonder how it will perform together with a linear amplifier for that function
It's a shame that they cannot be shipped from Europe. The VAT/import duty and handling fees make it a less attractive option than it could be. It’s a promising piece of kit though. Thanks for the review.
Very nice piece of hardware!
Wow! A USB dongle that transmits directly to a satalite?
Pretty much yes, although you need a few more items to make it work.
@@TechMindsOfficial is a tinfoil hat one of those items?
Can you use it just to transmit for example 1500 MHz like a hello world program just blasting out a frequency ?
Well done. 73 KM6TRZ
Amazing, another toy to get this year...
It’s for ever ending this hobby! 😂
I own one of these and the documentations is quite clunky
Seems I should really dig in to SDR and get away from ole analog, HF Rx using discrete (oh mhe ghaD) components. all that work still in progress. Interesting presentation!
Did you have crashing problems when changing the frequency in sdrconsole? Seems to do it with the latest version.
Yep, I get the same issue. I tend to set the frequency before starting the Radio now, but it’s frustrating of wanting to scan quickly. I’m sure it will be fixed soon tho, fingers crossed!
Same here!
@@TechMindsOfficial I just read on the mailing list that it will be fixed in the next version due around the 28th January.
Hello, I would like to buy limeSDR or limeSDR mini, but I need 8 channels, the signal is a simple radio pulse, decimeter frequency range. I know that mini has 1 receiver and 1 transmitter, but could I get 8 channels with digital channel separation? could you recommend suitable models?
Please make video to compare hackRF bladeRF & limeSDR
indeed nice toy to play with :)
Hello. Thanks for posting..Can you suggest an RF amplifier to boost the Lime SDR transmit signal ?
I believe there's now a rf front end available check out the limesdr or crowdsource site
For the TXRX to the local repeater can you tell us what hardware you used (eg antennas, rf filters, rf amplifiers, cables)?
Looks to be a very interesting project. Do you know of any amps for 10-20mw in and 10w + out? I would love to see this for APRS, Winliink and 2mSSB
Are these things really backordered until Feb of '22? They seem to be a great option for an SDR Transceiver.
thats neat could be very useful indeed
Super interesting, thanks. You mentioned using it as an exciter ... what will you use for the RF amp?
If I’m going to QO100 then a popular choice is a modified 8w WiFi amp which are relatively cheap, it will need something between it as I’m pretty sure the LineSDR mini won’t drive the amp enough.
I have that same usb hub and its not working. Device not recognized
Great videos m8, De M0RAY, Mid Kent, However, I do wish you would talk a little slower in them. I'm finding that I need to play them several times over, & then look for them again having seen the ones that interest me most.
Kind Regards,
Ray,
M0RAY.
Hi Ray, thanks for your comment and watching. My older videos were a little fast, but my more recent videos I have slowed down to a more manageable pace. Thanks again 🙏
Just slow down video playback in UA-cam, Ray.
I listened to this video at 2X speed no problems.
How about going down to DC? Starting at 10Mhz closes the door on a lot of Amateur communications. I'll just stick with my Ettus N200!!
Very nice
Good job bro.....nice video
Thanks! 🙏
it would be very interesting if it would run from 10 khz! Now we need to have a downconverter......
If I use this to transmit HDMI video, is there any way we can introduced AES encryption? Furthermore, can Lime SDr Mini can communicate with regular Lime board? I am assuming yes.
Have a like. Nice presentation.
Thankyou 🙏
Hello sir, I wanted to use the raspberry pi & portsdown as an independent transmitter so that when it boots up it automatically starts transmitting the webcam image through the limesdr. This way it wouldn't need an LCD anymore.
Is this possible to perform the commands through a linux script and automate this process without the use of LCD?
What’s a good web based software solution to make this into a remote listening station / ham radio. I’d like to be able to have this connected to my roof antenna on a shot cable and then access the RX and TX of local 2m and 70cm ham repeaters from any computer or mobile device inside the house and not be tied to my shack. Like a remote head that runs over IP network... either web based software or some kind of application or iOS app.
Since no film is used, it would be live video, not live footage.
Hi friend am need your help am running a radio scanner thro my laptop for digital frequency am using dsdplus. Just asking how to upgrade the software to run conjunction with me radio scanner.. Any help would be very appreciated. 👍👍👍
Hi Pete, take a look at my TRX 1 video, I take the Audio out from the headphone/discriminators jack and take it into the pc audio input, mic socket, then use DSD+ to decode digital. That might give you an idea of what you need to do .)
@@TechMindsOfficial hi friend.. I have the discriminatory.. Is the dsdplus software the only one for the digital frequency. Or is there any other software maybe better quality.. Many thanks peter
Have you got the Fastlane edition of DSD+ ? It’s way bette then the standard version. If you don’t have it, take a look at the read me file that comes with the free DSD, it will tell you how to get the Fastlane edition :)
@@petesyoutube8680 I had little luck with old dsd version and descriminator in a scanner. Recently bought two nesdr smart dongles. They took a bit of setup finding drivers, but work great! Have been following and decoding trunked digital Motorola system for a few days on a "mini pc" I've fitted in a Pelican case. It has been working good (have one problem now I think I caused). If you are wanting to monitor trunked digital with unitrunker and sdr there is a video that was very helpful to me. It's by Tahoe Steve, titled "Unitrunker, DSD+ Plus, & Virtual Cable Installation & Config for Digital Trunked Scanning"
Hi@@juliogonzo2718
Thanks for the info more than welcome. 👍 Am running a unidan bearcat radio scanner.. But it as the disclaimer in it for the digital frequency on me laptop I have got dsdplus.. So do you think it would be better with the dongle
Many thanks peter
I would want to put an amplifier behind it and try it on 2 m
What is a good amplifier in this case?
@@ErnestGWilsonII Do you need a pre or post band pass filter if you use an external amplifier ?
I'd like to know more, are you going to use filters?
@@miomatteo Someone should do a video on how to properly use SDRs with external filters and amplifiers.
Amplifiers that take in mW andoutput watts are typically much higher than those walkie talkie amplifiers too. A 150 - 174 MHz one @ 600 mW in - 100 watts out from Cresend is around $2500. Pretty sure the low split ones are the same price.
anyone can show me, where i can buy this device? iwant to build mini BTS with range 1Km..

LimeSDR, LimeSDR, LimeSDR = 350€ for the setup.
Nice 🤣
HackRF One 65€ 😄
Yeh, but you’re missing the full duplex support with the HackRF :) Anyhow I use Pluto now
@@TechMindsOfficial I understand but LimeSDR does not cover the band up to 6ghz and the khz band like the HackRf One.
The high cost of LimeSDR and the low bandwidth does not justify the price. However in some applications the LimeSDR is better for sure
Unfortunately it's really expensive. I went with the HackRF, I wish the HackRF was full duplex
Adalm Pluto is full duplex
Pluto doesnt support HF band!
@@Mark300win Check out Ailunce HS2 or Q900 SDR
Would it work for WSPR?
In theory yes, don’t think there is a direct WSPR app as of yet, but can be done with piping audio from WSJT to SDRangel and then using Vox. It’s on my list of videos to create :)
can it be used for GNSS Spoofing?
Hi, nice video. I noticed that the UI of SDR Console is a little "sticky". This means that it periodically freezes for a short moment. Do you know why?
Yup, I experience that too. Even with the later version of SDR Console. It's not just the LimeSDR it does that with, it's most connected radios. Wish I could figure out why too, also I get crackly audio, but my computer spec is way higher than needed. I was going to reach out to Mr Brown, but I expect he is busy.
It does tend to skip a bit also. Try SDR++. Much more lightweight
Where can I get one
I'm trying to get a device that simultaneously transmits and receives, duplex transceiver that has ports for external mic input and audio output that sits between my audio interface and smartphone that I Bluetooth connect to my smartphone (just like an earbud) but that allows me to tie the smartphone into my audion interface for wireless Bluetooth phone calls. I know how to do it hard wired with an attenuator, and made a video on that. I don't know why there is not a fairly inexpensive device that is seen by the smartphone as something resembling Bluetooth earbuds with mic, but the device instead of being a Bluetooth headset is a device with ports for sound and mic. I know it's easy to build, but I don't want to do it. I'd prefer to buy the device, without spending $700 for a Rode Procaster II. I have all kinds of interfaces and just need the Bluetooth adapter that does that one function in the Ride Podcaster II. Hate spending that much for one little function.
very interesting. price is a little high for me
Compared to what?
Please!
Take a class demonstrating how to update the Lime Sdr Mini firmware on Windows 7 and 10.
Also with all the necessary configurations of the Lime Suite Gui to operate the QO-100.
Thank you!
73 from PU2OZK
How much its cost
How do you RX/TX under 10MHz?
Can i decode dvbs2 signal from satellite and can I also decode gsm signals?
DVBS2 yes! Try using SDRangel. GSM, sort of, but not fully, I think
Hey did you face underrun and overruns in gnu radio using full bandwidth or sampling rate ?
There was scenarios where the RF output became choppy, but I’m not sure if it was an issue with the LimeSDR mini itself or the PI doing too much work. I think they mention it should be okay upto a symbol rate of 2000 on a pi 3, but I think that’s too much for the pi. just a shame it’s not supported on the Pi 4 yet!
Tech Minds can you check tx rx rate test on windows machine and share the redults on 30 Msps
Sure! Will get back to you
Tech Minds plz check full duplex and tx and rx separately too if possible
I show full duplex in my video, altho very brief
What can hams rock on 2.4ghz power wise in uk?
I think that's just wifi
@@NapertI don't think u are actually a ham. I think u talk about needing license 2 cover your ass. Most ism band is international and wifi has always been a sketchy thing to run as a ham u would know why it u had a license. Also it would have been good practice if not legally required to say your call during the portion u transmitted for
😃👍👏👏👏
How much?
Almost 200 euro. That's a pricey rf hotspot.
Just find the specification of LIme SDR For its specs the price is OK if nto to say cheap wiki.myriadrf.org/LimeSDR-USB
...and compare with any other SDR of this range. NO transmit , smaller freqs range , smaller bandwidth and many more for 230+ euro..
BUt for sure i will not buy it because i m not interested in using it
WERE DO YOU GET IT?
He mentioned in the description
Kickstarter...
Sdr
I dont like hacking and im not hacker but this tool can hack any tv i heard that on another video
*Separate*
300 dollers🤔
Badly mudulated! WHO CAN UNDERSTAND IT?
Andras Bato whats over modulated?
There is no such thing as “the interweb”
Harrzack obviously! 🤔
I have posibility other same to limesdr. Is very expensive .73 ce3vna
very expensive kit
20mW is not going to go far. I don't see the point, especially not for $300.
If you want to go further then you use an amplifier. I have successfully used this to transmit a signal on 2.4 ghz through the QO100 satellite which is 1000’s of miles away from me. Video coming soon btw
No Case, won't Buy it!
