Software Defined Radio Kits
on: November 22, 2010, 21:42

I have built several of the software defined radio kits put out by KB9YIG. These are small PC boards that connect to an antenna, battery (or power supply) and the sound card in your computer. With a normal sound card you have a bandwidth of 48 KHz and with a high end 24 bit sound card you can see a 96KHz portion of a band.

Best way to see what this is about is to go to VE3NEA's website

and, after reading the info, download the software.

The receivers are extremely selective and quite sensitive. There is also a new QRP transceiver kit for 30 and 40 meters that works on SSB, CW and digital modes.

Now for the good part: the receiver kits cost US$11 and the transceiver kits US$32 including shipping.

Many hams use the panadapter display in the SDR software by building a receiver kit tuned to the IF of their station transceiver.

You can see some photos by looking me up on and following the link to my photo album.

Please do not hesitate to contact me with any questions.
