Many thanks to SWLing Post<\/em> contributor, Dan Van Hoy, who writes:<\/p>\n

[Regarding the reception of DRM via smart phone<\/a>,] I happened to find this KTWR Guam post<\/a> about decoding DRM30 with a smart phone, app, and an RTL-SDR:<\/p>\n

Convert Smart Phone to DRM 30 HF receiver!<\/h2>\n

We are pleased to report successful use of an SDR Dongle used to directly receive and Decode DRM 30 over HF today.<\/p>\n

The SDR Dongle is an\u00a0RTLSDR v3<\/a>\u00a0type connected to an android smartphone using an OTG cable (phone or tablet must be\u00a0OTG capable<\/a>).<\/p>\n

The Software used:
\n1.\u00a0Android driver<\/a>\u00a0(free)
\n2.\u00a0DRM+SDR Android App<\/a>\u00a0($4.99)<\/p>\n

The Frequency of the HF broadcast is directly assigned within the\u00a0DRM+ SDR app<\/a>\u00a0with two settings
\n1. Frequency in Hertz
\n2. RF Gain (0-512)<\/p>\n

Demonstration\u00a0video<\/a>\u00a0showing Clean DRM decode of AAC Audio and Journaline data along with live metadata.\u00a0 (our signal was very strong, so only a short wire used for Antenna, DX’rs will need an appropriate Antenna)<\/p>\n

Now anyone with a smartphone and a\u00a0$20 SDR<\/a>\u00a0can receive DRM 30 HF broadcasts…<\/p>\n<\/blockquote>\n
