arecord loopback solution
Simple solution Just use:
arecord -f cd - | aplay -
If you wanna play while saving:
arecord -f cd - | tee output.wav | aplay -
This will help with the latency:
arecord --buffer-time=1 - | aplay --buffer-time=1 -

Dan Robinson comparing Russian Malahit DSP-2 to the Chinese clone
Dan Robinson wrote an article comparing the Russian made original "Malahit" DSP-2 (~$200) vs the Chinese clone who have upped the version number to DSP-3, but will be referred to as the "HFDY V3" (~$180). The original Malahit DSP-2 from "Malahiteam" is a portable SDR with built in speaker and touchscreen. It has a frequency range spanning between 50 kHz to 50 MHz, 50 MHz to 250 MHz and 400 MHz to 2 GHz.
There are several clones out there, but Dan notes that the Chinese "HFDY V3" version appears to be superior in terms of build quality with its high quality metal construction, high quality knobs, two antenna jacks for AM and FM, good internal shielding, and front firing speaker with beautiful gold grill. These are all improvements over the Russian made version, however it's important to note that the Chinese clone version comes with older firmware that must be carefully updated first, in order to obtain the same features as the original DSP-2.
Overall in terms of performance, after the firmware upgrade, Dan finds no difference in performance between the two. Dan goes on to mention that both the clone and original suffer from grounding problems and sensitivity to touch especially with shortwave.
Finally he notes how Malahiteam are planning a new higher end more expensive product which will include an optional add-on for enabling reception up to 6 GHz. The estimated cost of the new version will be $480 with the 6 GHz add-on, and $42o without.
Dan adds updates to his Malahit SDR and variant reviews
