Unless I miss my guess, I would say that this is the latest incarnation
of the Minima. A general transceiver with the mixer replaced by a
multi-diode unit, the VFO a variation on the Si5351 DDS, and a somewhat
simpler circuit than the BITX40, but multiband. It will be interesting to know
what the IF is...
In other words, a new HF-1 transceiver.
