We are pleased to announce release 1.8.0 of the API for the SDRplay RSP. This is a major upgrade to the API with new features and an improved gain map which should result in improved performance over a key portion of the gain control range. Currently this API is available for Windows only, but versions for Linux and Mac OS and Android will follow shortly. The API now incorporates automatic post tuner DC offset correction and I/Q compensation. This will almost completely eliminate the DC centre spike that was previously present in zero IF mode and also correct for amplitude and phase errors in the I/Q signal paths that can lead to in-band images when strong signals are present. There is a new gain map for the RSP which should help improve the receiver noise floor for gain reduction settings in the range of 59-78 dB. Bt Lifter L2000u Manual.

To achieve this, the IF gain control range has been increased from 59 to 78 dB. In addition, the user can now turn the LNA on or off at any point within the IF gain control range. This means that the LNA can remain on for gain reduction settings of up to 78 dB, whereas previously the maximum gain reduction that could be attained whilst the LNA was on was only 59 dB. Being able to leave the LNA on will result in improvements in the receiver noise performance for gain reductions in the range of 59 to 78 dB. The upper 19 dB of the IF gain control range have now been disabled. In practice this part of the gain control range was useless as trying to operate within this region always lead to receiver overload even when signals were very weak.

To fully exploit the features of this new API release, we have also issued release 3.5 of the ExtIO plugin. This plugin will work with HDSDR, SDR sharp (releases 1361 or earlier) and Studio 1. Automatic I/Q compensation and DC offset correction will work with later versions of SDR sharp, but we will need to update the native plugin for users of these later versions to be access the new gain map. Similarly, users of SDR Console will gain the benefit of automatic DC offset compensation and I/Q correction, but will not yet be able to access the new gain map. We hope that a version of SDR console that unlocks this feature will become available in the near future.

Until a new release of SDR-Console is available, you can copy the API into the SDR-Console installation directory from C: Program Files MiricsSDR API x64 mir_sdr_api.dll to C: Program Files SDR-RADIO-PRO.com mir_sdr_api.dll The API installer has also contains an extra certificate to be more user friendly for Windows XP, Vista and Windows 7 users. The new API and ExtIO plugin can be downloaded from our website.

Lots of great reference sites out there on this TV dongle showing how to enable a truly broadband programmable receiver. (see [.]as a great starting point) NOT FOR RECEIVING TV IN THE USA It works great with the current drivers and SDR# software on my XP desktop. The antenna is very short so do not expect any serious performance unless using something more substantial. The MCX antenna connector is hard to find, but my next step will be to mount this in a small box and solder a cable to a BNC connector. At less than $20 for the entire dongle package it would be crazy to spend as much or more on expensive connectors! Works fine on local FM stations and some Public service activity too. No success yet on 1.09GHz ADS-B signals, but that may require a better antenna.

Way cheaper than a Funcube dongle. My HackRF One works great. I couldn't be more pleased. Unless there is a standard robust software application out there for every platform that replaces all of those GRC blocks in GNU Radio Companion with some nice attractive knobs, dials, switches, buttons, gauges, and blinky lights, lol. The device arrives of course with no instructions, manuals, or software. You're pretty much on your own at this point.

And it's because this device is so versatile, it would be a never ending job to try to document all of the various ways this device could be used (many yet to be invented). You will need some technical knowledge and background in operating systems, programming, and radio to fully appreciate what this device is capable of. If you just want to listen to radio, go buy a radio.

But if you want to explore. These are cheap SDR dongles, but perform very well. I bought them to use in a SDR set up for following MotoTrbo trunking and they work fine with the software I have. There is a wide variation in frequency accuracy, so be sure that you have a way to enter frequency correction. One dongle is 49.1 ppm off and the other is 62.3 ppm off.

Once that's dialed in, they are very stable and don't need any retuning. One star off for the variation in frequency, but they are still pretty good. I'm using this on a portable set up, so I didn't want to spend a whole lot in case something happens to that.

These fit the bill. I use this in tandem with Nooelec's DVB-T dongle with the Elonics 4000 tuner. My antenna is a 43 foot vertical.

I must say this is a poor man's/tinkerer's entry into the world of shortwave listening using Software Defined Radio. I use this to listen to AM radio, shortwave broadcasters, HF aeronautical, hams on 160/80/40/30/20/15/10 meters, time signal stations, other utility stations such as FAX/RTTY/DGPS/LF beacons/ALE, etc. It is stable enough to decode FAX, RTTY (you need other software to decode these stations though). For the price what you get in fun and listening pleasure is unbelievable. Comodo Dragon Browser Portable Download. And this is from someone who is a ham for 35 years and a shortwave listener since the mid-60's. Since purchasing this product I am now a victim of sleep deprivation - cannot go to bed, I'm having too much fun using it!
