N1MM Logger+ Announces a New Website

Amateur Radio contest logging software N1MM Logger+ has a new website. Changes include fewer pages, better search capability and bug/issue-tracking visibility and reporting, and a comprehensive, easier-to-use listing of all supported contests. The N1MM Logger+ online manual now consists of 31 web pages, reduced from the previous website’s 104. An expanded menu eases navigation to the desired page directly from a drop-down menu.

“The program’s features are continually changing, and the manual may sometimes fall behind the code when this happens”

All of the logger’s more than 400 supported contests are contained within one table that can be sorted, searched, and filtered.

First on-air test of FreeDV 2020

David Rowe VK5DGR reports on the first on-air tests of the new digital voice mode FreeDV 2020

Brad (AC0ZJ), Richard (KF5OIM) and I have been putting the pieces required for the new FreeDV 2020 mode, which uses LPCNet Neural Net speech synthesis technology developed by Jean-Marc Valin. The goal of this mode is 8kHz audio bandwidth in just 1600 Hz of RF bandwidth. FreeDV 2020 is designed for HF channels where SSB an “armchair copy” – SNRs of better than 10dB and slow fading.

Mark, VK5QI has made a 3200km FreeDV transmission from Adelaide, South Australia to a KiwiSDR in the Bay of Islands, New Zealand. He decoded it with the partially working OSX version (we do most of our development on Ubuntu Linux).
