HF reception with the experimental driver is very poor in comparison to the direct sampling hardware mod or an upconverter, but even so Jengal was able to receive AM Radio, an SSB ham radio signal and an HF weather report with a simple longwire antenna. Teejez’s modification tells the RTL-SDR to bypass the tuner in software, allowing antennas to be connected to the normal antenna port. It works by connecting an antenna directly to the RTL2832U chip, thus bypassing the tuner. The direct sampling mod is a hardware modification to the RTL-SDR which allows it to receive HF frequencies between 0-14.4 MHz without the need for an upconverter. The modified dll is compiled from keenerds experimental branch of the RTL-SDR driver, which uses code for the no hardware mod written by tejeez. The no hardware direct sampling code was inspired by Anonofish’s discovery where he found that the E4000 based RTL-SDR could tune to AM radio without the need for the direct sampling mod (though this appears to be now patched in the newer rtlsdr drivers). Over on the Reddit RTL-SDR forums user Jengal has posted a modified RTLSDR.dll dll file for SDR# which allows the direct sampling mode to be used on the R820T without the need for any hardware modifications. The new mod seems to work better than this one. Update: There is now a newer driver that allows HF tuning without hardware mods via a different mechanism.

Defending yourself from rival miners will take time, resources and skill, with success leading to new territory and new lands. The intergalactic mining industry is a profitable one, but you are not the only miner in search for new worlds to exploit. More will be added as development progresses. Treacherous mountain ranges, luscious grasslands and huge deserts are among the biomes you will encounter. The worlds in TerraTech are procedurally generated and infinite, so there are always new lands to discover and more resources to find. Be it powerful armoured combat vehicles, unstoppable resource gathering machines, sprawling resource processing bases or a hybrid of all three – creativity is your key to exo-planetary success. Using the building blocks, guns, wheels, and wings from several Mining Corporations, you can build varied Techs to suit every purpose. Team up with other intrepid prospectors in Co-op Campaign, build and create together in Co-op Creative, go head-to-head for glory in the Deathmatch Arena or battle for supremacy in Sumo. Start your career as an Intergalactic prospector in search of profit and glory in Campaign, build to your heart’s content in Creative mode or pit your Techs against the clock in the Gauntlet Challenge. Scavenge, craft and buy new parts in order to survive and become the ultimate planetary prospector. Design cars, tanks and planes from a huge library of blocks. TerraTech is an open-world, sandbox adventure game, where you design and build your own creations through a mix of crafting, combat and discovery.
