For Soundcard Input: select "CABLE Output (VB-Audio virtual cable)".SWR stands for “standing wave ratio” and is a measure that can be used to tune an antenna for a particular frequency. The closer the SWR is to 1:1 at the designed antenna frequency, the better the antenna will receive (and transmit). In his video Adam shows how he measures the SWR of an ADS-B antenna which he has built and is selling.

Also, with an additional piece of hardware called a directional coupler the standing wave ratio (SWR) of antennas can also be measured. Measuring the response of a filter can be very useful for those designing their own, or for those who just want to check the performance ...Example - SDR. SDR for a 10 inches ASTM D2241 - PVC Pipe with outside diameter 10.750 inches and wall thickness 0.168 inches can be calculated as. SDR = (10.750 in) / (0.168 in) = 64. A SDR 64 means that the outside diameter - D - of the pipe is 64 times the thickness - s - of the wall. with a high SDR ratio the pipe wall is thin compared to ...SWR aka Standing Wave Ratio is calculated for the reflection due to an impedance mismatch along the transmission-line. This is more relevant to Tx because of the power levels involved. Ergo, SWR calculation will only be applicable to a receiver insofar as a 1:1 (or as close as may be achieved!) indicates the signal incident on the antenna is ...20151028. Preface: This manual is for the mcHF transceiver, the original design by Chris Atanassov, M0NKA, as an open- source SDR (Software Defined Radio), both in terms of Software and Hardware.

VOLUME:A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously. SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.The RFNM is an upcoming software defined radio that has some impressive high end specifications only seen in SDRs costing thousands, and at the same time the creator claims that it will be priced at a steal. While no pricing has been set, the creator noted in a Reddit post that pricing will be 'closer to $500', bringing it's price similar to SDRs like the HackRF, bladeRF, LimeSDR, PlutoSDR.fractional SWR values from being plotted correctly by European users. v1.3.0 - February 5, 2013 -- Added list box with plotted SWR values. v1.2.1 - February 5, 2013 -- Changed to restore original frequency after analysis. v1.2.0 - February 4, 2013 -- Added ability to change maximum SWR shown on Y-axis of chart.
