  1. Hi all,

    as an old ham radio operator I am very interested on SDR and all related to it.

    I got my ham license some 30 years ago and I was playing with TNC's,antennas,rf power tubes for a long time.

    That said,back to SDR.

    These dongles are fantastic...You can do almost everything (receiving) and they are very cheap.

    From my personal experience....the one with the Elonics tuner (E4000) is the best.

    Sensitivity..frequency range...construction...rocks!

    Just one downside...it comes usually with the standard tv connector.

    PLEASE....do not use any adapter!!!

    Just desolder that ugly connector and solder on the board a 5 cm. of rg58 and a N Connector.

    Keep cables very short...and use quality connectors....(soldering an N male connector is an art!)

    I got a lot of links on mods....converters and antennas...if You are interested....just drop me a line and I will

    share.

    73's

    IK6....

    ;)

  2. Digip...I do not own one yet...

    what i know is very stable,non very fast with Debian+lxde.

    Really think is the perfect hacking platform.

    If someone succed to connect to the PI a led display,it will be fantastic.

    Reflex...keep on working on PWNPI !

  3. I am following the evolution of the project,must say it could be the perfecy HACKMACHINE.

    It gets power from usb,good excuse to connect to anybodys pc to "recharge".

    Can plug a very inexpensive BT and show the pwnned how it can be use as a remote keyboard use an android phone.

    Wardriver drone...perfect use.

    Keylogger.....PI is very small.

    Debian ARM and Fedora is running on this device.....a custom stripped backtrack arm is a dream?

    Smart TV project.....

    Video surveillance and video streaming....security monitoring...

    I really think PI should be take as a base for 100 cool projects.

    And I couldn't imagine a better place than here,HAK5 community!

  4. Try this...for me worked a lot of times.

    30/30/30 reset

    This is the first attempt to reset the hardware if you get locked out or if you misconfigure the router. The 30/30/30 reset is supported by almost any router. Actually, I’m not really sure if that is 100% correct but it doesn’t take much time to test and that’s why I tried it and I’m posting it here. It’s called the 30/30/30 reset because you will need to press the router’s reset button for thirty seconds for three period. Firstly, while the router is plugged in and running, press the reset button and keep pressing for thirty seconds. After the thirty seconds pass, remove the power jack but keep pressing the reset button. After another thirty seconds, plug in the router and keep the button pressed for another thirty seconds. If you do this correctly, the router should be reseted and ready to be bricked again. As I mentioned earlier, I didn’t have any success with this method so I’m just referencing. It defenitely works the try.

    Then ...if the FW is openwrt based...

    You can SSH in and type

    mtd -r erase rootfs_data

  5. The "mast" of the Yagi-Uda's antennas is at "ground"..electrically and physically....

    so You can use any clamp to fix somewhere.

    The tripod needs to be very stable,because hi-gain antennas have a very sharp radiation pattern.

    Antennas do not "create" any power...they just direct the signal in front...mostly..and back...some.

    16 db over isotropic antenna (think about a sphere) is not bad at all.

    But You need to keep the cable very very short....You can waste a large amount using low quality ones!

    Also old tv parabolic antennas may be used with success.

    But remember...You will often need a laser to pont the antenna to establish a good link.

  6. 50 Watts?No...it is not a good idea on the microwave spectrum!

    First You will face big problems if you try to home-made it,teflon PCB is a must....

    shielding is difficult,switching even more.

    And you will have to use INFLEX cable to connect the PA to the antenna.

    Very unconfortable cable...to pass outside of the house.

    And You need an Ham licence.

    Connected to a proper parabolic antenna,we used to test for EME communications.

    ...1 Watt with a modified tv parabolic antenna,

    will give a boost enough for your tests.

    Working on high gain antennas is the right way to go.
