LIME MINI USB UP-CONVERTER

#1

Unread post by IK2NBU »

Dear Friends

I set my Lime SDR as shown in the photo to have an IF at 150 MHz.
In transmission it works perfectly from 14 MHz it transmits at 164 Mhz,
while in reception at 164 MHz I receive nothing.

Where am I going wrong?

Thanks 73 Arnaldo ik2nbu

Is not a Hardware LIME problem, with HD SDR software the Downconverter work properly (see the image).
