I would be interested in your opinion on adding digital modulation types directly to SDRSharp. Digital modes like DMR, D-STAR, P25, NXDN, YSF and others are already as common as FM, AM, SSB or CW. I know there are external plugins available to decode digital modes, but direct implementation into SDRSharp would take this program to the next level. I suppose if digital mode decoding is functional as a plugin, it should be technically feasible to implement it in SDRSharp. *What is your opinion about direct implementation of digital modes directly into SDRSharp?* Thank you for your time.

What do you use for your day to day SDR listening?

So, I have been busy integrating a new theme library (ie. skins) to SDR#. The library is not free, but if there's enough demand, we can push it. This adds ~6 MB to the download (12.5 MB unpacked). The memory usage is still reasonable (< 100 MB) and most of it is paged. The current build is still under test, and I am still negotiating the licensing terms to allow plugin developers to skin their plugins as well for a coherent and professional look. So, which theme do you like the most? Fluent Dark: Fluent Light: Crystal Dark: Crystal Light: Visual Studio Dark: Visual Studio Light:

I found this video on YouTube from Tudor Vedeanu (who is also in this mailing list) : https://www.youtube.com/watch?v=pSy0Mzz7URY I was wondering if you would be interested in a Raspberry Pi Extension Hat ( https://www.raspberrypi.org/blog/introducing-raspberry-pi-hats/ ) that provides the same functionality as the current HF+ ? Basically, it would *eliminate the USB link,* provide a *very small form factor* and possibly reduce the power usage. In the end, the resulting system can be either used directly with GQRX, GNU Radio or run the SpyServer and stream the IQ data to all your PC's. Imagine all the possibilities of this small, self-contained, high performance SDR system you can power on batteries. What do you think? Please vote and comment.

I was checking my notes for alternatives to the current Airspy R2/Mini design and wondered if consulting the community would give some constructive input. As the market is already crowded with low cost receivers and transceivers, but yet Icom manages to sell a 4 figures SDR, I was thinking of making something that is as open as possible for extensions and work good enough for the most demanding operators and pro's, all while being affordable. The idea is to replace the R820T2 tuner with one of its latest high performance siblings, then replace the old LPC4370 with the brand new i.MX RT1020 ( https://www.nxp.com/products/processors-and-microcontrollers/applications-processors/i.mx-applications-processors/i.mx-rt-series/i.mx-rt1020-crossover-processor-with-arm-cortex-m7-core:i.MX-RT1020 ). This MCU can be interfaced with a good ADC ( http://www.analog.com/media/en/technical-documentation/data-sheets/AD9629.pdf ) and has enough processing power for oversampling and decimation through the Cortex M7 core, which will bring the final resolution higher. The general goals: * Better RX performance than the general purpose low cost silicon transceivers * 12 bit RX at 10MHz bw and up to 16bit at narrow band * Coverage from 30 MHz to 1.8 GHz or more * Switched pre-selectors * Open source * Same form factor as the Airspy HF+ (same box actually) * Leverage the RF manufacturing and testing capability developed at Itead Studio * Affordable What do you think?
