A few of my favourite multiband recievers. More information will be added as the collection grows.
This is a hybrid SDR reciever, when connected to an HF rig can display a waterfall - the Spectrum DSP M4-Plus has a touch sensetive 5-inch XGA LCD. The M4+ version with intergrated extension port allows access to support wide-band allmode transceiver, covering 1.6 to 54* MHz, including FT8, WISPR & SSTV, when fitted with HF head unit.
