Digital Radio Mondiale Receiver Digital Radio Mondiale Receiver Sachin Anchan (Mechanical) (OP) 9 Oct 17 07:23 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. RE: Digital Radio Mondiale Receiver MacGyverS2000 (Electrical) 9 Oct 17 15:06 Plenty of cheap off-the-shelf SDR kits out there... some even in the <$100 range (but not by much). $50 may be asking a bit much unless you design every inch of it. Dan - Owner http://www.Hi-TecDesigns.com RE: Digital Radio Mondiale Receiver VE1BLL (Military) 9 Oct 17 17:06 DRM is a format (several related formats) used in various frequency bands. AM, SW, FM and perhaps L-band (not sure). 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. RE: Digital Radio Mondiale Receiver VE1BLL (Military) 9 Oct 17 17:14 It's worth noting that the common consumer chips do not directly sample at RF. The USB SDR sticks include a tuner stage that down converts the RF to an IF frequency. RTL2832 R820T seem to be a common set of chips. eBay is still full of them. There are others.
