PMON - An Independent Pactor/Winlink Monitor For The Raspberry Pi

SCS, the company that created PACTOR has released PMON software for Linux to allow over-the-air monitoring of PACTOR 1/2/3 transmissions for meaning. Additionally, PMON automatically decompresses B2F/LZHUF compressed messages on the fly. This is very useful for monitoring Winlink email transfers. The program requires only minimal hardware: an inexpensive Raspberry Pi 3 Model B+ (minimum) computer and an inexpensive USB sound device. An SCS Pactor modem is not needed.

The program is a free download for radio amateurs from a Linux repository provided by SCS. Easy-to-follow instructions, program information and documentation are provided on this SCS web page.

Thank you to John Huggins and Gordon Gibby, MD for their original decoding programs, and to Hans-Peter Helfert and the SCS team for this welcome contribution to the amateur radio community!

Baja Radio Club XE2BNC Helps Hawaii Communications During SET

CREBC - XE2BNC provided a 20 meter long haul link on Pactor to facilitate Hawaii ARES. http://hawaiiares.info/

The island gateways all see each other well on 40 meters. One drill aspect was to test long haul HF forwarding in the event of regional internet outage.
To this end a reliable communications link needed to be provided from the Islands to the West coast of the US.
Most gateways tend to use omni directional antennas and when bands cooperate connectivity can be obtained on 20 and 17 meters.

New Experimental HF Propagation Map

Lee Inman of the Winlink Team has mined the server databases for useful propagation data and developed a new map showing recent HF connection paths on a worldwide basis. You can view the new map here.

Stations that do not report gridsquare positions (especially gateways) can not shown. If you aren't seeing your QSO's check your software settings. BPQ gateway programs generally do not report positions for sessions. The controls in the upper left of the map should be self-explanitory, but if not let us know. Mouse over a path line and see details of the QSO.

Please send us a comment if you like the map, and make any suggestions you feel would make it more useful to you.
