Despite my programming issues with my LimeSDR mini it seems that I am able to tune well below the 10mhz range that’s specified. I’m listening/receiving some FT8 transmissions at 7.074mhz. Can others also receive below 10 mhz?

I believe the mini only goes down to 10mhz. The bigger brother goes lower.

You can go below 10MHz with LimeSDR-Mini as well. Just RF matching network is not optimized for this freqyency range.

@Zack,

How far down can the LimeMini tune…? Let me know on that - I assumed that the RF ASIC wasn’t capable of tuning below 10 MHz but if it’s 7002-based it can tune like the flagship LimeSDR. Again, let me know -

Hi @martywittrock,

LimeSDR-Mini is LMS7002M based. Hence tuning limitations are the same as for LimeSDR-USB. But, as I said before, RF matching networks are not optimized for frequencies below 10MHz.

@Marty It seems 40m HF reception is decent. I haven’t tried much below that.
