ATS-4 and SDR Cube
Two exciting new possibilities for portable HF have become available. A few hours ago Steve Weber KD1JV announced that the ATS-4 kit was available again. These apparently sell out very quickly – so if you’re interested, act now! Many people … Continue reading

SDR Cube
A summary description of the SDR Cube from a recent message from George N2APB t the NUE-PSK list:
“The SDR Cube is a single-band, multi-mode QRP transceiver. SSB, AM, CW and digital (though the NUE-PSK modem). The rig’s band is determined by the type of Softrock “RF front end” you have installed, but the default is 20m if you order that option from us. You can put it on different bands, if you wish, by using a different plug-in module on that Softrock, as is widely available in the Softrock community. Many guys already have Softrock receivers and transceivers – any of which will work with the SDR Cube, and they just install it inside the box, or provide connection to it via a plug on the back.
Several other distinguishing features of the SDR Cube really make it attractive: an live, +/- 4 kHz “bandscope” function showing live spectrum on the graphic display, binaural audio output, RIT and XIT, four memories and two VFOs, CW shaping, adjustable audio filtering with graphic filter’s display, a great level-controlled RF front end, a memory keyer supporting Iambic A and B modes, and a tight integration with the NUE-PSK modem for digital mode support.” Continue reading

How long will it be before an app is developed and released for the new iPad which will enable you to remotely operate an SDR? The opportunity to use more screen real estate more effectively must be well-suited to such … Continue reading
