Digital Radio Mondiale Receiver
Digital Radio Mondiale Receiver
(OP)
I am planning to build a low-cost DRM only receiver($50).
In this regard, looking for help to building a low-cost SDR which could provide IQ data and tune frequency range from 500kHz to 1.7MHz.

The SDR USB sticks were getting as low as US$6 with free shipping. The typical ones didn't directly receive below about 35MHz.
For lower frequencies, like SW, converters were offered. About $100. Offset started at 100MHz, but shifted to 125MHz due to FM broadcast interference.
Now they're built-in. And crazy cheap.
Random example from eBay.
Even if you really want to build one, it might be a good idea to buy one first.

RTL2832 R820T seem to be a common set of chips. eBay is still full of them.
There are others.
