... and also ... The one you posted the other day (which I am going to get)
NooElec - NooElec NESDR SMArt - Premium RTL-SDR w/ Aluminum Enclosure, 0.5PPM TCXO, SMA Input & 3 Antennas. RTL2832U & R820T2-Based.
NooElec - NooElec NESDR SMArt - Premium RTL-SDR w/ Aluminum Enclosure, 0.5PPM TCXO, SMA Input & 3 Antennas. RTL2832U & R820T2-Based.
I am by no means a radio engineer, but my understanding is that Airspy has a much better SNR so weaker signals can be listened to, has more sensitivity, and has more selectivity. Radios which do these things cost more hence the Airspy prices. Teamed up with Spyverter, you get the shortwave stuff without the imaging issues due to the hardware in both Airspy and Spyverter. They are also in metal cases with SMA connectors.
I guess there must be some misconception that Airspy is a high end RTL-SDR. It isn't. It is a completely different piece of hardware. There is no RTL2832 chip in it. It does use the R820T2 chip.
Airspy.us has a promo that is about over. They had the Airspy R2 for $149 and Spyverter for $39 but they are out of stock on those. They still have the Airspy Mini for $99...
Airspy.US - Your USA source for quality SDR products!
SDR# use to allow RTL-SDR to do ADS-B, but they stopped doing that and instead have a better version of that software which works with Airspy which is their product. For RTL-SDRs, the only one I ever found I liked was DUMP1090.

Irrelevant; the 1ppm is a specification on stability of the oscillation frequency, not on the frequency itself. If your frequency is off (and you really need it to be on), you calibrate it by hardware or by software and you let it rip... and if the spec is correct it's frequency will not vary more than 1ppm and you will have a stable oscillator which is very desirable, and much more important than one that is precisely on frequency in most applications, and most certainly in an SDR.
Today was an Ebay offer with 15% off and I ordered 2x Nooelec SMArt Dongles.
Does anyone know what is different? I will use it for Automated Decoding.

So now I got the bill and the say:
NESDR SMArt Premium USB RTL-SDR w/ 0.5PPM TCXO, Metal Case, SMA. R820T2 RTL2832U
NESDR SMArt - Premium RTL-SDR Set w/ 0.5PPM TCXO, Aluminum, SMA. R820T2 RTL2832U
omg... I thought the were the same oke oke oke... does it make any difference?
I ordered both separately on ebay hopefully the dont send it in 1 parcel! Separate Shipping is important to be under the Custom Tax Limit.
