I've been adding optional timestamps to the waterfall. Here you see very high resolution as well.

Here you see the BBC Radio 4 transmitter on 198kHz with the Economy 7 signal on the carrier. For more info: http://en.wikipedia.org/wiki/Economy_7

A preview of version 1.1 is available here: http://www.sdr-radio.com/Downloads/BetaKits.aspx

This is a 'warts and all' kit so that users can see that some progress is being made. There is also a lot of work taking place behind the scenes to support the new netSDR and SDR-X2. There should be a major announcement from RFspace before the end of August which will blow your socks off!

Polyphase Resampling

simon@hb9drv.ch — Wed, 14 Jul 2010 17:41:00 GMT

As part of the DSP design deep in the bowels of the console it's necessary to change the sample rate of the data being processed.

The general description of the polyphase resampling algorithm can be found, for example, in "Multirate Digital Signal Processing" by R. Crochiere and L.Rabiner, Prentice Hall, 1983.

By changing the code I use from an open source implementation to the implementation provided by Intel in the IPP library I've cleaned up the audio a great deal as shown in this screenshot - look at the AF Spectrum in the bottom left.

Kenwood TS-590S

I saw the nice new TS-590S today at the Ham Radio show in Friedrichshafen (Germany). Looks very nice, I am sure it will sell by the shed load. Otherwise the show was a very big disappointment.

HF Radio Integration

simon@hb9drv.ch — Mon, 24 May 2010 15:25:00 GMT

I'm now starting the HF radio integration, with luck it'll be available for testing within two weeks.

Kenwood, Elecraft, Yaesu (new) radios
Use SDR connected to IF out or kept in sync with the HF radio
Simple to use
Complex to code

Let's see what happens :)
