The highest safe sample rate is 2.56 MS/s but in some situations up to 3.2 MS/s works without USB dropping samples (RTL2832U drops them internally).
Because the devices use complex sampling (I/Q) the sample rate is equal to the bandwidth instead of just half of it.

This resampled output can be up to 3.2 MS/s but 2.56 MS/s is the max recommended to avoid losing samples. The samples themselves are unsigned and you subtract 127 from them to get their actual value.You'll almost certainly notice a stable spike around DC.From this a 28.8 Msps stream at 8 bits is produced.That can be resampled inside the RTL2832U to present whatever sample rate is desired to the host PC. The actual output is interleaved; so one byte I, then one byte Q with no header or metadata (timestamps).A visual introduction by 3Blue1Brown, Quadrature Signals: Complex, But Not Complicated by Richard Lyons) This is complex-sampled (I and Q) by the ADC.
The Sigma-Delta ADC samples at some high rate but low precision.

Originally meant for television reception and streaming the discovery and exploitation of the separate raw mode used in FM reception was perhaps first noticed by Eric Fry in March of 2010 and then expanded upon by Antti Palosaari in Feb 2012 who found that these devices can output unsigned 8bit I/Q samples at high rates. rtlsdr as we know it today was created by the osmocom people in the form of rtl-sdr and osmo SDR, keenerd is the author of many other rtl_* tools: rtl_fm, rtl_power (heatmap.py), rtl_adsb and code changes accepted into the mainline. The dongles with an E4000 tuner can range between 54-2147 MHz (in my experience) with a gap over 1100-1250 MHz in general.

Although setting up email account in Nokia N900 is quite straight forward, but if your outgoing email server requires authentication, there are few options which need to be defined correctly before you can start sending emails.
Pressing power button would not have any effect at all! Nokia N900 has numerous exciting open source applications but not all of them are available in the Official Application Catalogs. With Linux based Operating System, Nokia N900 is very powerful smart phone, and best IMO, available in the market.
