New Perseus 22 announced
« on: June 24, 2022, 1040 UTC »

Perseus22 is a 4 channels, direct sampling receiver with a continuous frequency coverage from 10 KHz to 225 MHz and a typical image rejection larger than 70 dB.
All channels are synchronously sampled by an high SNR, 14 bits A/D converter and processed by a software defined digital down converter, implemented on an FPGA, which outputs are routed to the host PC by a USB 3.0 controller, allowing wide-bandwidth IF applications.
The frequency coverage is split-up in 2 groups of channels (two for VLF-HF frequency range, the others for VHF), each one capable of diversity, which can reduce noise in order of tens dB. All channels includes an analog RF frontend equipped with attenuators, preselection filters and amplifiers.
The receiver enclosure is machined from solid aluminium and finished with a fine, non reflecting, black surface treatment.
RX: Elad FDM-S2, Grundig Satellit 700
Ant.: HDLA 3 (Active Loop)@315°, EWE @270°, ALA 100LN, MiniWhip
QTH: JO31 (Germany)

Could such a receiver (with two identical antenna inputs sampled in sync)
be useful for diversity receiving ? And varying directional effects ?

And much more, with the right software and two antennas separated the right amount, could it be used to dynamically cancel thunderstorm crashes ? (Even if the crashes are coming from various directions from second to second ?)

Was wondering if/when they'd reprise the Perseus.
