Reverse Beacon Network Beta Testing Separate Spot Stream for FT8
The popular Reverse Beacon Network (RBN) has announced that it’s now offering — as a beta test — a separate telnet feed for FT8 spots (telnet.reversebeacon.net port 7001), in addition to the current spot feed (telnet.reversebeacon.net port 7000), which will be repurposed to handle only CW and RTTY spots. In addition, a beta version of Aggregator Version 5 that can handle FT8 spots received from WSJT-X will be available on the RBN website, with instructions on how RBN node operators can configure their nodes to spot FT8 call signs on one or more bands; this will not interfere with the ability to spot CW and RTTY call signs, the RBN team assured in its announcement, explaining its reasoning for the move. The beta test follows a limited alpha test aimed at getting a feel for the spot load and other implications of carrying FT8 spots on the RBN.
“The most striking characteristic of FT8 spots is their sheer quantity,” the RBN announcement said, citing weekday statistics from May 23 and 24 when FT8 spots represented 86% and 87% of all spots, respectively, while CW spots were 13% and 14%, respectively, and RTTY spots were below 1%. Throughput on both days totaled some 30,000 spots.
“Whether due to the startling popularity of the new mode, or to the ability to spot stations at 22 dB below the noise level, it seems obvious that adding FT8 spots to our spot flow could have a huge impact on the infrastructure of the RBN,” the RBN announcement said. “These numbers suggest that if only 20 – 30 RBN nodes added FT8 spots, those spots could outnumber the total CW and RTTY spots being delivered by the 140 – 150 nodes currently active on the network, doubling the total required throughput.”
The RBN team said it wanted to find out whether RBN servers would be up to the task before the fall contest season. Read more.
Sailor Grateful for Maritime Mobile Service Network Assistance
Phoenix sailor and radio amateur Timothy Henning, KE7WMZ, has expressed his gratitude to the Maritime Mobile Service Network (MMSN) for intercepting and handling his distress call on 14.300 MHz. Net control operator Harry Williams, W0LS, caught Henning’s call requesting assistance with an
