@late2L3 @cemaxecuter What's the analog frontend in your book? The $20 LA9310? No, that's just honestly priced. The catch might be 8 Gbps PCIe bandwidth, maybe?

@cemaxecuter @BatchDrake Might want to drop the 300 grams worth of heatsink for the application :D But yes, you can use the local transport interface to get data to the iMX and process it there -- and it could be a 100/150 MHz wide spectrum, no problem.

@F4DAV @cemaxecuter @5N63S We can run a full 5G UE node when splitting the work between imx and vspa! Unfortunately yes, the nda is still in the way.

@FlUxIuS @viperbjk @cemaxecuter @ryzerth @enjoy_digital NXP has been nothing but amazing to work with. Here is why we discontinued Granita:

@redplanet00 I wonder if maybe the pre selection filters are what’s causing this? The ADC sampling frequency should only affect the baseband interface and nothing else. Lime baseband gains are fixed in our code. Maybe the same issue is present at 61 MSPS, just more difficult to see.

@TrippyTunesTV Yes, we are showing the way for the future of open, digital fpv. The right people will get behind it, eventually.

RT @rtlsdrblog: An Initial Review of the RFNM Software Defined Radio

@aang254 @rtlsdrblog I believe the blog post is talking about images coming from a poor IQ LPF, rather than the IQ imbalance problem (that yes, is a matter of automatic calibration).

@CJHandmer Check out the "making of" video from a decade ago. The world wasn't ready.

@simonroses Both boards are wideband and can do 2.4 GHz, but we recommend the $179 Lime, as the Granita RFIC is still showing limitations.

@nemanjan00 @ryzerth 2/3 months after we have raised enough to make it viable (~50k). We will manufacture less hardware if it comes to that.

@cemaxecuter Is there any toggle in CyberEther to enable the automatic DC offset inside our Soapy module? That's going to get rid of all four visible spurs here, not just the DC one :-)

@viperbjk Small comment: the jtag is for the la9310, not the imx — but if you need an imx jtag you can solder it to some test points (useful for the m7 core).

Here is a demo video showing a 3.7ms latency UE running with LimeV1 boards:
