Adding more capabilities to SDRUno workspaces could provide substantial improvements for using SDRPlay. Save and recall optimized radio configurations. Read more
Long Distance SSB Pioneers
Telephone carriers deserve the credit for most of the early development. They are the real long distance SSB pioneers. Read more
Radio Spectrum Processor – Good Name for SDRPlay
Radio Spectrum Processor is a good name for the SDRPlay boxes. Because they are not your normal kind of radio. Read more
Passband Tuning – SSB Receiver Innovation
At the beginning of the sideband era, engineers found interesting ways to move signals around to get different filtering effects – called passband tuning. Read more
Mirics MSi3101 Chipset – Heart of SDRPlay
The Mirics MSi3101 Chipset is the heart of SDRPlay RSP. It’s hard to believe that two chips the size of a fingernail produce such powerful radios. Read more
SSB Transceiver Era Begins in 1957
For me, the Hallicrafters SR-150 truly started the SSB transceiver era because it included Receiver Incremental Tuning or RIT. Read more
