Vocabulary
SDR
SDR - Software-Defined Radio (Software Defined Radio). A radio transmitter and / or radio receiver using technology that allows software to set or change the operating radio frequency parameters, including, in particular, the frequency range, type of modulation or output power, with the exception of changing the operating parameters used during normal predefined work with preliminary radio installations, according to one specification or another system.

POR performs a significant part of the digital signal processing on an ordinary personal computer or an FPGA. The purpose of such a scheme is a radio receiver or radio transmitter of arbitrary radio systems, modified by software reconfiguration.

Software radio has great utility for military applications and wireless services, as it allows you to serve a large number of radio protocols.

Equipment for ERP usually consists of a superheterodyne receiver, which converts the signal from radio frequency to intermediate, analog-digital and digital-analog converters (ADC and DAC).

It is disconnected, a firewall too, I execute everything from the administrator. I do not use antiviruses.
When I put it for the first time, I put it on top of firewood from the disk, now the disk is successfully lost.

Of course I ran
Zagid himself does not want to install, google, found dll separately, shoved, the effect is zero. Found a similar misfortune and everyone is advised to first put their own firewood
Before reinstalling Windows, this was not. 4 years worked with a bang.
The window remained the same vin7 (64)

Well, the topic is kind of like "Ham radio" is called. If I didn’t write there, please forgive me, and kick where I should, then I’ll suggest the necessary topic.

* black_stalker22 spiral? It doesn’t look like the color code of the resistors ... Ask here: Save, help!
I am not an electronics specialist



Rep: (84)
This is not a marking. The paint is burnt on your resistor and you see a resistive layer. All markings also burned out. The resistor value can be measured with a tester. If it burns, then measure by the surviving parts. Or see the diagram. Are you changing it? Put more power, but rather look for the cause of overheating.

Wire resistor. It seems that the wire in it is all burnt out. Judging by the small number of turns, most likely there was little resistance.

Yes, I probably didn’t see in the photo that this is a spiral groove. Such things happen on film.
