The problem: I remarked we have been spending a lot of time lately on problems that could be solved with much less effort if we all agree to adopt a minimum of discipline. As this mailing list grows, there will be less and less people interested in reading about problems they have already discussed, solved, and beaten to death in this same mailing list. Here's a quick reminder for everyone having problems with SDR software and computers. Unless you describe exactly what you are doing, in which context, with the exact hardware and software configuration, the odds of someone giving helpful advice are close to zero. The social media (and mailing lists) have the undesirable ability to amplify noise because there are naturally more people who have opinion than people who have actual knowledge. So please, read this post carefully. What do I do first? Use common sense. Determine if it is a support topic or a general discussion: Airspy Hardware related => Contact the support; Everything else goes to the list. For support related questions, prepare your list of "Steps to Reproduce" and send it by mail to The Support. For general discussion/best practices, try to avoid duplicates: Use the search bar to find an existing topic/answer/advice that solves your problem or improves your life. Don't jump on other's threads. Statistically, "Mee too" is never an actual "Mee Too". You are just making things difficult for all. Use separate threads for separate problems. A "segfault" has nothing to do with the noise from your Plasma TV or PC PSU. Try to keep the content technical. People from different cultures will read and ignore your untranslatable joke, but will definitely understand the tech stuff. How to report a problem: Steps to Reproduce Be precise Include exact data used during testing for easy reference, including hardware, OS and user software versions The steps have to be in the exact order Mention pre-requisites when applicable: Software dependencies, glibc, modified kernel, etc. Do not write composite steps. The devil is in the detail. Always recheck your steps to reproduce on a new system with the default configuration Make sure the sentences are short and unambiguous Thanks for reading to the end!

Understanding USB and PC noise 30 messages

USB cables radiate considerable noise greatly raising the background noise floor gawd awful to say the least. EBAY is one source having listings of triple shielded USB to Micro cables, some as short at 6 inches. What a difference a cable makes! Background noise radiated from the USB cable is practically non existent. Now the downside: A simple long wire antenna readily picks up considerable noise, even from the short triple shielded USB cable in close proximity to the USB cable. I've enjoyed great success drastically (understatement) reducing USP cable noise feeding the Airspy HF+ with a Mini Whip placed at some distance away from the receiver and laptop computer feeding the Airspy HF+. To put this is perspective---the original unshielded cable radiates noise so severely, that the considerable noise is transmitted to the mini whip placed fifty feet away. By the way, ferrite "clampons" have proven useless in reducing USB cable noise radiation. Last, but not least, ditch the switching power adapters for powering the laptop. These things are a disaster in terms of noise. Go battery power and a laptop computer if possible. Another suggestion, turn off the AGC and add reduce gain on the slider control. There is a point at which "spurs" across the visible spectrum suddenly disappear if IMD (false signals) is taking place. (Eliminate the noise, and what a pleasure it is listening around to high quality signal content!

Better RX for VHF/UHF 89 messages
#poll
A new poll has been created: 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
A new poll has been created: 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? 1. Yeah, that's a good idea! 2. Actually, I need two. 3. I want to contribute to the design. 4. I don't need more performance. I have enough radios.

Hello guys, For some obscure reason firmware flashing does not work for me on Win10 but it is ok on Win7. It looks like on Win10 nothing is found to flash (flash.bat behaves the same if Airspyhf+ is plugged in or not) despite SDR# works correctly. Any idea? 73 Giovanni Iz5pqt

No SDR# User Manual... Really!! 23 messages
#airspyhfplus
#sdrsharp
I have an Airspy HF+ that I enjoy using very much. It's a great radio!! I decided to try SDR#. Loaded it on my Windows 10 box, looks like a nice application with a lot of ways to tweak and adjust it.
I have an Airspy HF+ that I enjoy using very much. It's a great radio!! I decided to try SDR#. Loaded it on my Windows 10 box, looks like a nice application with a lot of ways to tweak and adjust it. I started digging into it and decided I needed to read the User's Manual and learn as much as possible about a seemingly great piece of software. Started looking for a manual and discovered that apparently there isn't one... !!!???!!! What's up with that!!! I apologize if there is a User's Manual and I just haven't found it yet, but I emailed my distributor asking them for a manual and they said the only documentation available for SDR# was on the Airspy.com site. I've been all over the airspy.com site and haven't found a user's manual for SDR#. If there is a manual available would someone kindly point me toward it? If there isn't a manual... WHY NOT?? It's ridiculous that I have to go to a forum to get information message-by-message about how to use a piece of software.

BW limits with Spyserver
Hi, is it possible to change the max BWs in SDR# when using R2 with Spyserver (not full IQ mode)? It seems to be limited to 156.25kHz in WFM mode, 4852Hz in USB/LSB modes and 9765Hz in all other modes
