FCC Grants Limited Use of Amateur Bands to AST Spacemobile

The Federal Communications Commission approved limited use of amateur frequencies for 20 satellites to be deployed by a Texas broadband company.

The FCC's Space Bureau said in a statement that it was giving permission to AST SpaceMobile to use frequencies between 430 and 440 MHz on an emergency basis only, The regulator said its move was in direct response to overwhelming concerns raised by amateur radio operators.

Citing potential interference among their issues, member societies of the International Amateur Radio Union, AMSAT, the ARRL and individual amateurs worldwide also argued that alternate UHF allocations exist for the satellites' telemetry, tracking and command functions. More than 2,500 comments were submitted to the FCC .

The FCC's action gives use of the amateur frequencies to the satellites for no more than a 24-hour period. The amateur radio 70cm band is used by hams worldwide for such applications as mobile FM voice, analogue and digital TV, digital data transmission, amateur radio satellites and weak-signal communications on SSB and CW.

AST SpaceMobile ultimately plans a full constellation of 248 satellites for broadband service from space.

Doubts About Solar Cycle Prediction Methodology

Like a solar storm itself, a controversy over solar cycle predictions is heating up.

As this year brings the solar maximum of Cycle 25, a different kind of solar storm has been raging - one that challenges the longstanding and prevailing paradigm scientists use to help arrive at forecasts. Sociologist and statistician Frank Howell K4FMH has done an extensive study of this so-called NASA-NOAA-ISED prediction formula, which utilizes a consensus methodology, pitting it against the work of solar physicist Scott McIntosh of Lynker Space.

In this busy, high-profile year for the sun and its activity, Frank has written extensively and presented a series of virtual talks on the subject in the US and overseas. He has also discussed the competing models extensively in his blog, K4FMH.com. Frank's most recent talk, "Progress in the Revolution: Sunspot Cycle Forecast Accuracy at Cycle 25," was given to Pennine Ham in the UK, and can be seen on their YouTube channel.

Whether the NASA team or the McIntosh team prevails, one thing is certain: Like CMEs themselves, this scientific competition over solar predictions promises to rage for some time to come.

UK Regulator Mulls Satellite-to-Cell Phone Service

Following in the path of countries such as the US that permit some mobile phones to use satellite connectivity, the UK is opting to move ahead to allow such services too.

The UK is poised to become Europe's first country offering legal satellite connectivity for smartphones. The regulator Ofcom has released a consultation authorising the move and is requesting comments no later than the 10th October 2025.

Making this service available to standard mobile phones would provide the most remote parts of the UK with the access needed to send texts, make phone calls or even connect to the Internet - functions presently not possible in areas without mobile phone coverage.

This is known as "direct-to-device" and operation would be permitted after Ofcom has provided a variation to the licences of Mobile Network Operators. The change would also grant such use to mobile handsets and any other devices that make use of SIM cards.
