WebSDR.org - background information. SDR technology makes it possible that all listeners tune independently, and thus listen to signals; this is in contrast to the many classical receivers that are already available via the internet. WebSDR was first conceived as a means to make the 25 m radio telescope at Dwingeloo available to many radio ...The "QMX" (Q RP Labs M ultimode X cvr): a feature-packed, high performance, five-band (80, 60, 40, 30 and 20m) 5W CW and Digi-modes transceiver kit, including embedded SDR receiver, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference.QMX may be used in CW modes standalone, or with a single USB cable to a PC for digi mode operation.Mostly for rolling codes like keyfobbing stuffs. So if you can afford it, or can afford waiting, LimeSDR (mini or not) and maybe a decent laptop with decent battery or just an rasp. Am no specialist though. But an portapack is basically, in 2022, just TX'ing over FM radios or so.
