Real Rado Amateurs?

This is what "Radio Amateur" should maybe be about in the 21st Century, rather than CW bugs, Echolink, DStar, collecting squares and off the shelf rigs.

From 1905 to 1950s Amateur radio was in the forefront of Innovation and Wireless Experimentation. Post Office Trunk circuit SSB applied to Radio etc after WWII.

NI Reception after 2012

Anyone near N.I. Border should consider a Saorview TV that has DVB-T2 tuner or a "Freeview HD" TV. ASO for N.I. on 24th October will dramatically increase transmission power and add more transmitter sites. An HD DVB-T2 multiplex will be added. Some sites may have a DVB-T2 "mini-mux" for a few Irish channels.

"Tatiana" a clone of "The Sweetheart"

Type 31/1 (Sweetheart) Battery Valve (Tube) Radio

Or "From Russia with Love" as we will recreate the design using the more modern and 1/10th price Russian 1j24b sub-miniature Pentodes. Since the unwitting Russian was Tatiana Romanova, I'll call the clone radio "The Tatiana"

The type 31/1, also known as Sweetheart, is one of the most beautiful clandestine receivers of WWII. It was developed for use by the SOE in 1943 by the Norwegian Willy Simonsen in the UK. It consists of a small body-wearable receiver, a separate battery unit and a tobacco tin that contains the earphones. Receiver and battery case are painted in blue/grey wrinkle paint.

DVB-T2 Lite

DVB_T2-logo The DVB Project has published details of a new profile for its terrestrial broadcasting standard, designed to support low capacity applications such as mobile broadcasting.

Version 1.3.1 of the Blue Book for DVB-T2 adds the new T2-Lite profile. At the same time the previous single profile has been renamed as the T2-base profile.

According to the DVB, T2-Lite is based on a limited sub-set of the modes of the T2-base profile, and by avoiding modes which require the most complexity and memory, allows much more efficient receiver designs to be used.

One possible use for T2-Lite enables the simulcasting of two different versions of the same service, with different bit-rates and levels of protection, which would allow better reception in fringe areas.

Download the specification here (DVB.org)

Development of DVB-h as mobile standard has basically been abandoned. It's unknown how this relates to the DVB-T2 "Lite" mux discussed for deployment of RTE/TG4 services in N.I.
