| AGC |
Automatic gain control |
| |
| ATT |
Receiver front end ATTenuator |
| |
| Carrier |
A steady radio frequency signal that is modulated to add an information signal to be transmitted. |
| |
| DBF |
DSP Bandpass Filter - enhances the receiver’s selectivity by allowing signals to go through it only if they are within a certain range of frequencies. It attenuates signals above and below this range. |
| |
| DNF |
DSP Notch Filter - helpful in removing one or more offending carriers from the audio passband |
| |
| DNR |
DSP Noise Reduction - enhances signal-to-noise ratio on weak signals |
| |
| DSP |
Digital Signal Processor - |
| |
| IF Shift |
Adjust the center frequency of the IF filter’s passband response. |
| |
| IPO |
Intercept Point Optimization - bypasses the receiver preamplifier |
| |
| PSK |
Phase Shift Keying |
| |
| RTTY |
Radioteletype - Digital mode where radio signals sent from one teleprinter machine to another machine. |
| |
| SSB |
Single Side Band - A common mode of voice operation on the amateur bands. Single-sideband signals use the upper sideband (USB -- that part of the signal above the carrier) or the lower sideband (LSB -- the part of the signal below the carrier). SSB transceivers allow operation on either USB or LSB. |
| |
| SWR |
Standing Wave Ratio - A measure of the impedance match between the feed line and the antenna. |
| |
| TCXO |
Temperature Compensated Crystal Oscillator - stable master oscillator so that the frequencies indicated by the radio's display are acurate and stable as the radio warms up. |
| |
| Watt |
The unit of power in the metric system. The watt describes how fast a circuit uses electrical energy. |
