It’s been a while since I last played with this, but I’m wondering if someone has a recommendation for a really good #SDR - receive only, a mix of #hamradio, #CB, #APRS…. Something with wide bandwidth so I could record say, all #FMRS or #GMRS channels at once, or listen to the whole #900Mhz #ISM band for #LoRA and #Meshtastic chatter.
I’d probably run it off a #RaspberryPi 500, so USB is preferred rather than PCI-E.

The RF heart of an old CT1 analog cordless phone.
So those 3x dielectric filters are all it has for a duplexer.
2x LMX1501 PLL's for TX and RX oscillators.
MC3372 FM IF on the receive side.
Maybe I'll bother beeping it put some day.
I do have 950-1400MHz VCO's in that case... 😁Sure, LMX1501 is rated to 1.1GHz only, but so is the MB1501 PLL and MB501 prescaler used in tons of Nokia equipment and those push fine to 1300MHz hamband.
