, 2011

The IDC-136-KIT is a 136kHz direct conversion receiver. Most of the SDR software

can be used with this receiver. It is quite easy to build within a couple of hours and

you can get ready to start receiving on the spot.

Specifications (subject to change without prior notice):

RX Coverage: 106kHz ~ 154kHz (when a 48kHz sound card is used)

LO Frequency: 130kHz (8.32MHz ÷ 64)

Operational Voltages:

～

13.8VDC

(The enclosure shown is not bundled. You need to prepare separately.)
