Hamtronics USB Computer Control

The project illustrates the use of USB connection which is a more convenient way to interface to a computer for the Hamtronics receiver.

Complete WLAN Solution for AVR and CPU

The project illustrates the use of Atmel AVR microcontroller based system with a Prism WLAN interface.

Transceiver Circuit with SSB 75 Meter

The circuit has been designed to produce a transceiver that switches the 4-element 1500 Ohm external BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T operation.

VHF Receiver Using Single Chip

The project was based on the KA22429 that is equivalent to a TDA7021 to create a small and cheap FM receiver.

Adding Zigbee Radio to NSLU2 (Slug)

The project illustrates the deployment of Zigbee radio on a small Linux box like the NSLU2 known as the Slug.

AM Voice Transmitter with Simple Design

The AM transmitter can be used near an AM radio that is tuned to 1000 in order to hear the sound source from the user in the AM radio or send voice and music across the room or street.
