VRX-Virtual receiver-A receiver having SDRPlay hardware
SR-
DEC-
HI Z - High impedance

I feel like adding one of the quite (I looked hard and searched the .PDF) undocumented things unique in SDRuno:

PDBPF = Police Department Beer Purchasing Fund, or maybe (just guessing here) Post-Demodulator/Discriminator Band Pass Filter = audio bandpass only working in NFM (Narrow FM) mode.

I thought I'd explained it reasonable well, guess I'll add a glossary at the end....

DEC = decimation
SR =? maybe left out a letter? SR = signal report, SNR= signal to noise ratio, SDR= software defined radio

there are some acronyms that get re-used depending on what technology you are talking about:
USB = upper sideband (radio), universal serial bus (computers)
LSB = lower sideband (radio), least significant bit (computers)

there are acronyms that get their meanings changed over time:
CW = continuous wave. at one time this meant morse code, but newer technology now refers to this mode as OOK (on-off keying)
and CW means the signal is on all the time with no modulation, or is modified with a different type of
modulation, as in FMCW which is a CW signal that slowly sweeps in frequency, and is used in various
types of radar

SR = Sample Rate
