Ham/amateur radio enthusiasts rejoice! Our MF/HF converter for software defined radio is finally available for sale. Don't let our price fool you, though. We believe this is the best SDR upconverter currently available. Here's why:
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
A maximum input level of +1dBm with LO at +7dBm
High-quality 2-layer PCB with ENIG finish
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. 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.
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!
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!

Also, I would like to know if this thing is capable of VLF reception?

Value Quality Performance
Works as intended and within 5 minutes had a working short wave receiver.
The up-converter looses 10db but this is to be expected, but I didn't notice as there is so much to pick up on the HF bands.
I would strongly recommend placing the up-converter and card into a box and with a bit of soldering run the lot from one usb port.
As for delivery, being in the UK the converter took almost 3 weeks to arrive. Not a problem with NooElect but the postal service. the up-converter had a nice holiday in Miami for several days. maybe overseas purchasers should be made aware that it can take up to 4 weeks to arrive. not a problem but would have been nice to know.

- Excellent item! Works as advertised. Review by Larry F. (n3lt)
This item is a great purchase for someone getting into SDR for the first time. I received mine on Jan. 24 and have just finished initially testing it with their SDR Starter Bundle which includes a DVB-T Dongle. It's performance has been excellent. The hardware combination of the upconverter, the dongle and the free download software, SDR# (not included with any purchase) work well together. It was easy for me to get it all going with no hassle other than my own ignorance. The upconverter certainly works as advertised, and its construction quality is very impressive for any amount of money. I consider this to be a wonderful buy. I, therefore, give both NooElec service and the up-converter a "5-Star" rating due to its performance, ease of use, and quality construction.
Thanks Again NooElec for a quality product and excellent service.
