My Perseus is also down. Looks like a communications issue with mine, like the USB port is dead. To be honest I have not tried to have it fixed yet, I keep meaning to, but not yet. I guess the biggest reason is that I just do not miss it.
The Perseus is a very good receiver, and until I got my WinRadios it was my primary SDR, with my SDR-IQs and -14 as secondary’s. But after I got the G31, and later the G33, the Perseus only got used as a remote node. I left it online 24 hours a day for others to use, and seldom actually used it myself. Now I split my use pretty evenly between the RFSpace NetSDR and both Excaliburs. The SDR-IQs and -14 really only get used for scheduled recordings or to watch specific things for extended periods of time. The Elad FDM-S2 almost never gets turned on.
As for the RadioJet, I did not like the original 1102 because of its narrow 24 kHz spectrum display. It may have been a very good receiver but in several of the areas where SDR can stand out it was limited. The 1305 + does look interesting, since it looks like they took the original 1102 and added built in RTL Dongles to the mix, this gave them the excellent performance of the 1102 plus the width of the RTLs. They mention being able to use other SDRs in their software, to stitch them together, WinRadio, Perseus, etc, and that could be very interesting. SDR receive capability from 20 kHz to over 1700 MHz is pretty intriguing. The upcoming RFSpace CloudSDR will have that kind of coverage also, but possibly using better hardware. I suspect, from the RadioJet description that the radio is 8 bit above 32 MHz, but there is no detailed technical description to go to.
T!
