The radio spectrum scope (also radio panoramic receiver, panoramic adapter, pan receiver, pan adapter, panadapter, panoramic radio spectroscope, panoramoscope, panalyzor and band scope) was invented by Marcel Wallace - and measures and shows the ...

5. SWR meter - Wikipedia

   en.wikipedia.org/wiki/SWR_meter

   By analogy, the measurement cable is a crystal radio (non-discriminating receiver) representing all the radio receivers that might suffer interference from dirty emissions. Though called an SWR Meter, a low measured ratio indicates not only good match, but also clean A3, F3, or G3 emission without excessive harmonics nor spurious (out-of ...

   MacLoggerDX is a full-featured amateur radio contact logger for macOS with Transceiver control, Rotor control, Callbook lookup, QSL handling (Hardcopy / LoTW / eQSL / Club Log), DX Cluster and spotting, and basic contesting support.

7. WSPR (amateur radio software) - Wikipedia

   en.wikipedia.org/wiki/WSPR_(amateur_radio_software)

   An Agilent Modulation Domain Analyzer 53310A showing the narrow band 4-FSK signal produced by a Raspberry Pi. Occupied bandwidth is about 6 Hz; Synchronization is via a 162 bit pseudo-random sync vector. Each channel symbol conveys one sync bit (LSB) and one data bit (MSB). Duration of transmission is 162 × 8192 ⁄ 12000 = 110.6 s.

8. Signal strength in telecommunications - Wikipedia

   en.wikipedia.org/wiki/Signal_strength_in...

   For very low-power systems, such as mobile phones, signal strength is usually expressed in dB-microvolts per metre (dBμV/m) or in decibels above a reference level of one milliwatt . In broadcasting terminology, 1 mV/m is 1000 μV/m or 60 dBμ (often written dBu). Examples. 100 dBμ or 100 mV/m: blanketing interference may occur on some receivers

9. Two-tone testing - Wikipedia

   en.wikipedia.org/wiki/Two-tone_testing

   The combined test signal can be injected directly in to the receiver if the antenna is removable. A second directional coupler, connected in the conventional configuration, can be used to provide a feed of the input to a spectrum analyser. This allows confirmation that the input signal is free of intermodulation products.
