M17 Foundation Responds to Statements made by MMDVM Project Maintainer

/

The M17 Foundation has responded to a number of grievances and rumors expressed by Jonathan Naylor (G4KLX), the maintainer of the MMDVM project. Along with dropping M17 support from the MMDVM project earlier this week, G4KLX posted statements critical of the `M17 Project's management and technical implementation.

The response from M17 is a point-by-point rebuttal of G4KLX's statements.

With M17 support removed from MMDVM, amateur radio operators potentially lose access to the M17 digital voice mode via hotspots and repeaters.

The M17 Project is an open source digital voice and data protocol that is positioned as an alternative to digital modes that require use of proprietary encoders.

MMDVM is an open source project that enables amateur radio hotspots to support multiple digital voice modes including D-STAR, DMR, YSF, P25, NXDN, and POCSAG.

National Bodies Protect 70cm Band

ARRL The National Association for Amateur Radio® has filed comments with the Federal Communications Commission (FCC) to oppose part of an application that would impact the 70-centimeter amateur band for telemetry, tracking and command (TT&C) of satellites. The application, from AST & Science, LLC (AST), requests “unprecedented authorization to 430-440 MHz for a constellation totaling 248 satellites to communicate with five ground stations using up to five channels with up to 256 kHz bandwidth.”

The formal opposition, filed by ARRL’s Washington Counsel, asserts that the permission AST seeks to use the 430 – 440 MHz band “should be denied because AST does not demonstrate need for TT&C spectrum beyond that available within existing allocations.”
