The Arecibo ionospheric HF heating facility will be operational for a research campaign from 24 to 31 July 2017. Because the facility transmits on the HF frequencies 5.125 and 8.175 MHz, it is possible that its signals can be heard world-wide. QSL cards are available for interested SWLThe new Arecibo ionosphere HF heater nominally transmits 600 kilowatts net power (100 to 200 megawatts effective radiated power) and has a unique Cassegrain dual-array antenna design that increases the gain of three crossed dipoles for each band using the signature 1000 ft spherical dish reflector.

The QIKCOM-1 module containing an APRS transponder and Terrestrial Alert beacon will be deployed from the ISS on 21 Aug 2017.
 
Built as a student project Amateur Satellite module at the Naval Academy, and attached to the NovaWurks SIMPL spacecraft, it will function identically to the ISS transponder on 145.825 MHz with the same ARISS alias and once they widely separate, will permit possible dual-hop experiments between it and the ISS APRS digipeater.

I’ve received community feedback that people want more guidance on running JT-modes during the SEQP. As a result, we have revised rules. There are some also changes to provide guidance in other areas as well, including using SNRs or RSQs for digital mode signal reports. None of these changes affect the scoring procedure, but hopefully they will make the operating procedures more clear. Also, I’ve been made aware that there is currently a bug in N1MM+ that prevents SEQP signal reports from being saved to ECLIPSE Cabrillo files.
