v1.2 - RF Upconverter For RTL-SDR; HF Converter R820T E4000 RTL2832U

Description:

- v1.2 - RF Upconverter For Software Defined Radio. Works With Most SDRs Like Funcube, RTLSDR (RTL2832U with E4000, FC0013 or R820T Tuners); MF/HF Converter With SMA Jacks
Now shipping v1.2!  Major changes include:
    Sturdier USB-B connector supplants the micro-B connector used on v1.0
    Filters completely redesigned for 125MHz operation to move the LO away from the broadcast FM band.  Of course, a high-quality 125MHz oscillator is included
    USB shield separated from USB ground
    Other components in the RF path revised for improved SNR
- Ham/amateur radio enthusiasts rejoice!  Our MF/HF converter for software defined radio is finally available for sale, and with free world-wide shipping to boot.
- Don't let our price fool you, though.  We believe this is the best SDR upconverter currently available.  Here's why:
 
Features:
    Female SMA for both input and output for a wide array of connectivity options
    In-line SMA connectors.  Much easier to connect and manipulate than side-by-side SMA connectors
    Antenna protection on RF input; in-circuit in both enable and passthrough mode
    Solely high-quality components used in the RF signal path
    Powered by common USB-B USB for a multitude of power options
    RF-suitable power supply regulation (TPS79333)
    PTC fuse on USB power input to protect your upconverter from short circuits
    Upconverter enable/passthrough toggle switch--less fiddling with small, delicate cables and connectors
    Socketed oscillator for a simple upgrade path
    Stable 25ppm oscillator included
    LO disabled in passthrough mode
    High-quality 2-layer PCB with ENIG finish
    Fully assembled and ready to use
    Designed to fit standard off-the-shelf Hammond enclosures
    2 mounting holes for standard PC screws
    Designed and manufacturered in conjunction with Opendous Inc., an excellent open-hardware design company
- Full project documentation--schematics, PCB design files, assembly information--is freely available (see link above).  DIY'ers rejoice!  We will have a limited number of bare PCBs available for those who want to 'roll their own'
- A portion of the proceeds from your purchase will be used to support this and other open-hardware, open-source initiatives
- BONUS!  We had space left on the PCB, so rather than waste it we have added a noise source circuit at no additional cost!  We have even populated most of the components for you.  We have kits of the components required to complete this bonus noise source circuit available for a small additional fee.  Details of the noise source circuit are available with the project documentation, and a detailed image of the circuit can be seen in the pictures above.

Operation:
- Before operating your unit for the first time, and every time you run with a new SDR, we recommend running the tuning procedure located here.  It is not a mandatory procedure but may help fine-tune your, erm. tuning.  Pop the included oscillator into its socket and you are ready to go!

Operating the unit is very simple:
    Connect your antenna to the RF input
    Connect your SDR to the IF output
    Ensure your toggle switch is in the enable position
    Plug your USB power source into the USB-B USB jack
    Fire up your favorite SDR software.  Tune to 125MHz (+/- the tuning offset from the tuning procedure) + your desired frequency and enjoy!
