Arduino CW Decoder Video

Dan Trudgian M0TGN has released a video about his Arduino Morse decoder project

He wanted to create a project that would 'inspire' young electronically minded students that might have an interest in radio - (i.e the Morse code) some coding experience and some construction / electronic interest.

VHF/UHF/Microwave SDR Transceivers

50-4000 MHz SDR Transceivers were given to attendees at the recent Chaos Computer Camp. 

The @rad1obadge transceiver is a full-featured SDR Transceiver with an output power of 5-10 dBm.

It is based on a Wimax Transceiver which sends I/Q samples in the range of 2.3 to 2.7 GHz to an ARM Cortex M4 CPU.

The CPU can then process the samples stand alone for various applications (like FM receiving, Spectrogram display, RF Controlled power plugs, etc.) or send the samples via USB 2.0 to a Computer where they can be processed with the help of GNU Radio.

The extended frequency range is provided by a mixer that can be inserted into the RF path. For immediate usage, the board contains a 2.5 GHz chip antenna which can be replaced with an easily soldered Antenna connector for usage in different frequency ranges. The radio also contains an LCD and Joystick as did the r0ket from last year's CCCamp.

£6bn Radio Replacement Emergency Staff May Put Lives at Risk

A £6 billion project to replace radios used by the 999 services with a system that uses the 4G mobile phone network has been condemned as ‘reckless’ and ‘short-sighted’ amid fears it could put lives at risk.

The UK Home Office is planning to overhaul communications for emergency teams within two years. But police chiefs, crime tsars and industry experts say that the project is being rushed through to save money. 

A report by UK Newspaper - The Mail on Sunday can reveal that:

• Civil servants are insisting that police forces start moving to the new system by next year – even before there is full coverage across the country, despite warnings by Chief Constables.
• The public will be left struggling to call 999 in a disaster, as they will be using the same 4G networks as emergency services, who will take priority.
• Police insiders are concerned that the new system may not work on the London Underground, as was required after 7/7.
