Pi-SDR IQ
|
Dear all, ? After quite some prototypes and testing,its time to move on with a new breed of interfaces that will take advantage of the major leaps in embedded technology and add benefits to our SDR community. ? These are the Pi-SDR range. ? On this new breed, first we will have I/Q interfaces for Ensemble homebrew kits. ? The new interfaces are designed to suit the specific SDR ADC/DAC needs of Softrock/Ensemble homemade rigs. ? Also they are designed to work with a network connection giving versatile topology. That means the Pi-SDR IQ interface will just sit happily with your rig and only an Ethernet cable connection is required to your local network. And of course have hassle-free operation, ready-made configuration with ease of setup. ? There are two initial interfaces, the Pi-SDR IQ and the Pi-SDR IQ Plus, the first, a cost effective solution with CS4270 codec and the second with the top performing AK5394A/CS4344 combo. ? Each, Pi-SDR IQ & Pi-SDR IQ Plus, will have an ADC/DAC board attached on a included SBC with a quad-core ARM A7 CPU running embedded Linux. They will be given as ready-made working combo packages. ? Both, Pi-SDR IQ & Pi-SDR IQ Plus, will have all the necessary IQ Rx, IQ Tx, Headphones, Mic, CW, USB host, all jack/connections for the Softrock/Ensemble and ethernet port for connection to PowerSDR. ? ? Their specifications ? Pi SDR IQ??(CS4270) priced at 90 € IQ ADC jack, 105 dB Dynamic Range/24bits/192KHz(128KHz linear) IQ DAC jack, 105 dB Dynamic Range/24bits/192KHz Stereo Headphones/Microphone jack CW/Paddles jack SBC ARM A7 QuadCore/1.53GHz/1GBRAM/100MBEth/USB2/HDMI ? Pi SDR IQ Plus??(AK5394A/CS4344) priced at 160 € IQ ADC jack, 123 dB Dynamic Range/24bits/192KHz IQ DAC jack, 105 dB Dynamic Range/24bits/192KHz Stereo Headphones/Microphone jack CW/Paddles jack SBC ARM A7 QuadCore/1.53GHz/1GBRAM/100MBEth/USB2/HDMI ? Photos and info can be seen here ->? ? ? For Windows users, these will be accompanied by a new PowerSDR application (based on v2.53) specific to utilize the new I/Q interfaces. Its operation will be transparent, just make the cable connections, start the application and you're up and running. ? For Linux users, since there is an included quad-core SBC running Linux, they can have an experimentation environment and even the possibility to create a stand-alone rig with software of their choice. ? The exact same IQ ADC/DAC boards can be connected if required to the Raspberry Pi 3, with a rewire configuration via SMD jumpers, as they share the same pinheader (RPi B+). Raspberry Pi though will need additional audio mic dongle if it is used for TRx. ? At works are also other rig types to be supported, eg. SDR1K, KX3, potentially any rig that has I/Q connections. These new interfaces do bring a new way on how we use our homebrew rigs, and quite some work is needed in ironing-out the additional software. Regarding delivery dates, pending on demand, dispatch is estimated a month after any order is received. ? Whoever is interested can contact me in sv1eia at yahoo dot com. ? ? Best regards & 73, Christos SV1EIA |

Surprise, surprise. Another over-priced interface that provides no significant, real world performance increment over a $25 USB interface. This is the "monster cable" of the SDR world.
Your $90 or $160 is far better spent on antennas. But there is one born every minute. And stay off my lawn.......... Warren Allgyer - WA8TOD |

He means a link not on Yahoo, which I think is an absurd expectation, since you likely do not have your own website, blog, or similar to post things like this on.

Hi Matthew,
Over the years I was using the Yahoo! groups for all that, on softrock40 or the powersdr-iq group which I mainly post relevant information and had no issues. Currently holding quite a few domains but never had the time or the urgency to use and work on them, in due time though the pi-sdr.com will be available for info to anyone interested. Until then, powersdr-iq and softrock40 can be used I guess. Of course, always anyone interested can contact me directly in sv1eia at yahoo dot com 73 Christos SV1EIA |

Thanks to Robby WB5RVZ, and his valuable assistance, here are some links he graciously offered in his site, for those who need out of yahoo links.

In the meantime effort is given to have a dedicated site up and running. Thanks again Robby. Regards & 73, Christos SV1EIA |

Hi Christos,
It is already mentioned in a previous post that the infoNO I CAN NOT!!! Soon there will be a dedicated site.Fine. It seems you will provide competition to the UADC by HB9DRI:-) A much better ADC will be useless with the Softrock unless the unit is modified. That is (the stupid) point Warren is making. With appropriate modifications and a top quality soundcard, the Softrock will outperform almost everything regardless of price. When you have a stable design that is sold to many I will want to buy one in order to evaluate it with a Softrock that is modified to make the best possible use of a good soundcard. 73 Leif |

Gee...... Thanks Leif! (I think).
Actually, that was not my point at all. My point was that most SDR users cannot take advantage of the increased dynamic range due to HF environmental noise, location, and compromise antennas. For these users, spending an additional $50 to $100 is going to allow no significant performance improvement. Hence the Monster Cable reference. Love and kisses, Warren Allgyer - WA8TOD |

Are the modifications to a Softrock to take advantage of a top end ADC and sound card documented anywhere please? Thanks.

Hi Leif,
I hope your recovery goes well. The Pi-SDR IQ as a concept in general focus mainly in the ease of configuration and operation. It opens up new possibilities for those who like versatility, networking, easily using PowerSDR-IQ, remote access, even a stand alone operation (with Linux) and all those neat to have things with a decent 105dB dynamic range. Effort is given to be tailored for the radio amateur use and everything is handled in that perspective. The Plus version does focus additionaly to the performance with 123dB dynamic range having the ADC choice of commercial SDR rigs, the AK5394A. So, there are many innovations here, ADC performance is only one of them. I'll contact you privately at a later time based on your availability for a sample evaluation when all is ready. Regards & 73, Christos SV1EIA |

While improved performance in the lower hf bands will not be possible due to noise levels, I would be very happy to operate my equipment remotely...about time we hams embrace high speed networking at least for our own convince. All the legacy stuff at 300 to, gasp!, 1200 baud is a bit of an embarassment when talking to others who are into modern networking. My interest comes from being retired and traveling around away from home much more than when working. I keep looking at the pi's, bought one to try, but always find it a poor value when we can go to places like Goodwill and pickup a older windows laptop machine for $29. Yes it needs $10?for new batteries and $ 50 for a new disc drive with more capacity than a pi would ever hope to have but the keyboard, display, ethernet ,and sound card are all there...and performance and the ability to run Windows / linux programs. It would be nice to run my ?connected radios at home from the tablet I am typing this message on. Just need the last 6 foot interface from the radio to the network. With DDS any radio we have can have its frequency controlled from a distance..including my tube rigs ;<) I guess the point is do not give up on old windows machines for a fancy relatively expensive toy that is a step back in relative performance. A soft rock permanently attached to a retired computer is the best bang for the buck most people have available to themselves. Ken K1KLW On Jul 26, 2017 1:14 AM, "sv1eia@...

Hi Ken,
Pi-SDR IQ primary function is to be used as a peripheral on a Windows PC (old or new) that hosts the PowerSDR-IQ application. You can use Pi-SDR IQ with your really old good bargain used laptop. After all, its size with its box is a mere 3cm X 6cm X 9cm Networking, remote or stand alone operation or Raspberry Pi option are neat stuff that happens to be available to whoever wants to experiment with them. 73, Christos SV1EIA |
