BEST SDR FOR MAC PC
Different tuner chips offer slightly different frequency ranges, but each accepts similar commands and thus can be controlled similarly.Īt first sight, there are many more PC and Linux apps to support RTL SDR devices. The Rafael Micro R820T (or equivalent, including the improved R820T2) is the radio tuner sub-system, for which the RTL2382U then performs analogue to digital conversion, and supplies data to the USB port. The groundwork was then continued by Antti Palosaari and Osmocom in 2012, since when many systems have been put to use as proper SDR.
BEST SDR FOR MAC TV
Originally and still used for digital audio broadcasting (DAB) and FM radio and TV reception, Eric Fry started to look at their use for more generic SDR in 2010. Conventional communications receivers with similar capabilities are far more expensive and bulky. Although some cover a smaller range of frequencies, most should be reasonably sensitive from VLF of around 100 kHz right up to microwave of around 1.7 GHz.
RTL radios are tiny, cheap, and really simple, but perform surprisingly well. One significant consideration with most RTL SDR kits is that the antenna ports on them are usually (very) miniature (SMA F), and you will need an adaptor to connect any other antenna to them this can be solved by a specialist ham radio store, or careful browsing in your local Maplin, etc. If you want more, then I recommend that you seek advice from a specialist ham radio supplier, and purchase a wideband compact antenna which you can mount high outdoors.
However for initial test purposes the little whip aerial supplied in some RTL SDR kits should be sufficient to get you started. Antennas are an enormously complex topic, and the large telescopic mast and antenna arrays in my garden illustrate the lengths (and height) to which you can go if you wish. The basic rule is that the more metal that you put up in the air, and the higher it goes, the better will be signal reception. Most apps which work with RTL SDR devices work with most such devices, so you are likely to be able to use any of those apps provided that you can get them to compile and link.
BEST SDR FOR MAC SOFTWARE
Although this is potentially frustrating, the cost involved is thankfully very low.Īnother advantage of using an RTL device, besides its low cost, is its generally good software support, even under OS X. Not all devices using the R820T and 2823 chips function the same, though, and there is no good way of knowing whether yours will, without putting it to the test. These can come as a simple USB stick or dongle, but mine has a miniature USB port which connects using a standard USB cable to any USB2 port, drawing power from that port.
BEST SDR FOR MAC FULL
I bought a “Yosoo UV HF RTL.SDR Radio USB Tuner Receiver R820T+8232 CW FM 100KHz-1.7GHz Full Band RTL-SDR Receiver”, which is one of a class of devices based on the Rafael Micro R820T tuner and Realtek RTL2823U chips known as RTL (the abbreviation for Realtek). If you want full transceive features (and have an Amateur Radio licence, as anyone transmitting without a licence is likely to be prosecuted), then you will be looking at a price well above £1000. To that you need to add the cost of antennas, but the best software is still free. It is, though, remarkably cheap at its most basic, with good USB systems costing as little as £20 ( $20). Software-defined radio (SDR) is still at the geek stage, so don’t expect to buy a polished consumer kit from Apple’s online store just yet.
