AVQA – Avoiding a crisis on the emergency frequency

A "resolved" radio issue turned out to be far bigger. AVQA revealed severe jitter affecting eleven radios across two sites, including both the main and spare emergency frequency radios. Had a real emergency occurred, controllers might not have been able to respond. AVQA isolated the full scope within hours, safety issue caught in time.

AVQA – Identifying an ATC hazard

After swapping an old analog radio for a new VoIP one, an ANSP could finally monitor RSSI remotely, and AVQA immediately flagged a high noise floor on multiple frequencies. Engineers traced it to a faulty electric fence around a nearby horse pasture. Turning the fence off confirmed it instantly in AVQA. Case closed.

AVQA – Quickly pinpointing an interference source

A controller complained about constant squelch on the emergency frequency, 121.500 MHz, with no actual transmissions. AVQA isolated the issue to a single receiver, showing the noise floor rising above the squelch threshold day after day. An on-site investigation found the cause: a defective power supply near the receiver. Case closed.

AVQA – Uncovering a codec mismatch

A controller calling an airport tower heard nothing but silence, even though every audio packet arrived. The culprit: a codec mismatch. The airport's device sent G.711 A-law while the ANSP device expected µ-law, the very codec the airport itself had proposed. A stark reminder that safety-critical comms can fail silently.

AVQA – Tracing phantom calls to a defective cable

A customer's DVR kept crashing, and the vendor got the blame. AVQA traced it to "ghost calls," recordings under 100 ms with no audio, amplified by frequency coupling. Searching for short squelch events pinpointed the source: a defective radar cable near the RX antennas causing EMI interference. Mystery solved, DVR saved.

AVQA – Detecting an interreference with ATC frequencies

During a trial, AVQA picked up unusually high squelch power every morning, a strange pattern the ANSP already knew about. A public radio station's transmitter was interfering with ATC frequencies nearby. The customer had it under control, but was glad to see AVQA could detect and alarm on it too.

AVQA – Revealing an ED-136 violation

A real deployment showed MOS repeatedly dropping below the ED-136 required threshold of 4.0. AVQA helped drill down to the cause: packet loss and severe jitter. At the call level, 1 in 11 packets was lost, not enough to be obvious to controllers, but enough to flag for the network provider before it became a real problem.

AVQA – Catching a gateway violating RTP standards

AVQA flagged a strange pattern: perfect voice quality during calls, but a MOS of 1.0 during idle times. Drilling down revealed the gateway sent non-standard keep-alive packets, breaking the sequence numbering RFC 3550 and ED-137 require. Radios saw this as massive packet loss. A clear compliance violation, caught before it caused real harm.
