Have you fa/g/gots heard of LimeSDR yet?
Looks like a 250USD equivalent to a ettus b210 software defined radio.Works from 100khz to 3.8ghz
https://www.crowdsupply.com/lime-micro/limesdr
Still in funding stage but looks promising in terms of specs,and its open sauce so you can look up more on github
https://github.com/myriadrf/LimeSDR-USB/tree/master/hardware
These guys are actually making it open and I think we should try to support em.
smells like BS
the specs surpass the of existing products too much

>Have you fa/g/gots heard of LimeSDR yet?
Sure. I am considering getting one but my working hours are too long to have much of a hobby. I am a licensed radio amateur so I follow the development in this area.
>>55028602
The chip it is built around is already in production and that is the hardest part.
>>55028248
Why would I need this? I already bought 3 RPi that are collecting dust.

The irony is strong.
a
Can it run an LTE cell?
>>55030656
Are you fucking retarded?
>buy SDR device
>run fake GSM cell
>collect device information from every person comes within 300 yd radius
>even route calls through my VoIP server and eavesdrop on the conversation if they have roaming enabled and don't check that they're roaming before making a call
>FCC knocks on my door one day
>takes all my equipment
>don't know when I will be subpoenaed or arrested
$499 for the complete usable package (case, cables and antennas)
It's still competitive ofc

Confirmed for fucking retard.

You ran your own IMSI catcher ?
>>55028248
>not using the B205mini-i with 70 MHZ - 6 GHZ
nope
$249 for those specs is pretty impressive. Would easily cost you 10x that to do it yourself (just the hardware) even if you got everything right the first time. Speaking from experience here.

>>55028602
Well given most existing products are just repurposed HD TV receivers I'm not surprised a purpose-made device does it better.
>>55028248
relevant to muh interests.
looks like a potentially awesome receiver or even transceiver for hams, particularly if it can put out enough power to drive a typical linear.
wonder how well the s/w works.
>>55036730
Looking at the specs for the Lime transceiver, it does have configurable low-pass filters, but not narrow enough for a lot of ham type activity. You would almost certainly want to add an external pre-select filter for the band you intend to use. This will keep the VCOs from getting aliased back down into the passband you are receiving. The rest of the filtering could easily be done by the FIR filters on the Lime device, FPGA, and PC after that.
I'm good thanks ;)
>>55031087
It can handle almost all of the frequencies and has 4 antennas so MIMO can work. Anyone know the limitations which aren't clearly listed?
>>55036862
Ettus?
Well funded too then.
>>55037777
For this money, it is very capable. Still, here are some things that I consider limitations:
>U.Fl connectors (mcx,mmcx,sma would be better)
>Small FPGA (Xilinx Artix-7 series would enable much more DSP)
>RX gain control limited to 30dB
>Hardware design files only useful on Windows (Eagle cad would be better choice for open project)
Does Ubuntu Snappy lock this device in to Ubuntu?
