Is there SDR for the GHz range of signals used by modern equipment?

You can get an AD9363 clone of the USRP b210 online for like, 300 USD?

The AD9363 stock is only supposed to be 325mhz to 3.8ghz but stuff like the plutoSDR which uses it manages to get the transceiver all the way from 70mhz to 6ghz like the more expensive AD9361 used in the real USRP B210s

Benefit is you can transmit stuff too, not just receive unlike the RTL-SDR which is RX only

Is there anything like this that can go down to 15 MHz or lower? including transmit and several analog modes of modulation USB LSB NFM WFM AM CW at least

If I understand what you're saying, you can do any modulation scheme with sdr, it doesnt depend on the model

Groovy. Are there any limiting factors such as processor speed and what is the best software that does it all on Linux? I have no idea what ratio of magic smoke is in the software vs. ratio of magic smoke is in the hardware.

There are levels to this that can get very expensive very fast depending on what your intent is, and how comfortable you are with programming various FPGAs.
