Many thanks to SWLing Post contributor, Dan Van Hoy, who writes:

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

Convert Smart Phone to DRM 30 HF receiver!

We are pleased to report successful use of an SDR Dongle used to directly receive and Decode DRM 30 over HF today.

The SDR Dongle is an RTLSDR v3 type connected to an android smartphone using an OTG cable (phone or tablet must be OTG capable).

The Software used:
1. Android driver (free)
2. DRM+SDR Android App ($4.99)

The Frequency of the HF broadcast is directly assigned within the DRM+ SDR app with two settings
1. Frequency in Hertz
2. RF Gain (0-512)

Demonstration video showing Clean DRM decode of AAC Audio and Journaline data along with live metadata.  (our signal was very strong, so only a short wire used for Antenna, DX’rs will need an appropriate Antenna)

Now anyone with a smartphone and a $20 SDR can receive DRM 30 HF broadcasts…

Trans World Radio to retire shortwave services to South Africa by December 31, 2019

(Source: Trans World Radio via Marcus Keulertz)

Due to changes to the media landscape and subsequent decline in demand for shortwave radio broadcasts in South Africa, TWR will be reducing our English morning broadcasts in the 49, 60 and 90 metre bands on October 27th – followed by a retirement of these broadcasts on December 31st.

We thank God for the impact these broadcasts have had over the last 45 years and wish to remind listeners that you can still enjoy listening to TWR’s English programmes on Satellite (DStv Audio Ch 855), Medium Wave (1170 AM from 8PM CAT) and via our TWR Africa App and TWR Africa Website.

For any assistance, or to request our new reduced English SW schedule, please reply to this email, and we will gladly assist you.
