DRM+ SDR
Read full descriptionHide full description
Decodes DRM (Digital Radio Mondiale) signals coming in through the external microphone input (LINE-IN) or DCP file input. (We need to supply DRM signal to microphone input.) The DRM+ SDR app is for DRM30 decoding with HE-AAC, OPUS and xHE-AAC. The paid DRM+ SDR app decodes sound, metadata, slideshow, web browsers. This app does not support decoding Journaline data in DRM signals. The DRM+ app requires a RC high pass filter audio line as well as a RF front-end module with antenna, tuner, modulator, IF mixer, AF amplifier. If a call is received while the app is running, please remove the audio line connected to the external microphone jack.

Verdict
The clearest difference is price: EchoLink at Free against DRM+ SDR's $4.99. DRM+ SDR's advantage is update cadence (every 2 months vs every 4 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
