It's safe to say that when they began PS Engineering in 1985, Eric Persson and Mark Scheuer (the P and S in the company name) had no idea of the evolution that aircraft audio would undergo. Almost two decades ago, the company launched the "sorely needed" Aerocom intercom, according to Scheuer, and it takes another leap forward with its combined AM/FM/CD/MP3 player, the PXE7300.
We met with Scheuer, who has flown with the new PXE7300 installed in his 1999 Piper Archer III for more than 35 hours, and we listened to a CD from Scheuer's Neil Young inventory as well as several local AM and FM stations. The audio was crisp and dynamic with a depth more akin to what you'd expect to hear in your living room than coming through an aircraft audio panel. The PXE7300 is a separate installation from the audio panel (in this case, a PS Engineering PMA7000B), and thus relies to a certain extent on the panel's quality — and that of the headsets — for audio fidelity. We listened through Bose X active noise reduction (ANR) stereo headsets, which transmit a frequency range between 20 Hz and 20 kHz, whereas the PXE7300 transmits between 1 Hz and 18 kHz. As a result we experienced almost the full range of the PXE7300 through the Bose sets.
The PXE7300 was designed from the wires up to be an aircraft system, and it shows. Similar to other PS Engineering units, just four buttons and two knobs on the face allow access to all playback functions. Sources available include AM, FM, CD, MP3 files (as stored on a CD-ROM), and five discrete programmable tracks that can be triggered by a waypoint alert from the GPS or a remote switch in the cockpit (useful for tour operators). A scan feature samples the strongest FM or AM stations, and recall and store features allow for memory presets. Other standard PS Engineering features such as Intellivox automatic squelch and automatic mute come with the PXE7300, as does an auxiliary jack for backseat users.
The AM/FM antenna is another win for PS Engineering — it's mounted inside the airframe, meaning no holes need to be drilled, and it's included in the purchase price. PS Engineering received its supplemental type certificate for the unit on October 15. Shipments begin this month. There are no limitations or placards against using the unit during IFR flight — no emissions interfere with other avionics. Installation time is estimated at six hours.

The Prop Club is a new security device that prevents an aircraft from flying by clamping a heavy steel lock to one propeller blade, thus creating an out-of-balance condition. It works best on constant-speed props, which have a flare near the hub that prevents the Prop Club from sliding off. However, a smaller version now in development will work on many fixed-pitch props as well. Dimensions will be published on the company's Web site as development proceeds. The smaller version is expected to be available this month. .he larger Prop Club is intended for turboprop aircraft and is available now.
The company also makes a Control Lock Club intended to replace the standard gust lock on most Raytheon/Beechcraft King Airs. It is used in the cockpit and serves as a visible deterrent, seen from the outside, that can thwart thieves from breaking into the aircraft. It locks the flight controls and the power levers. Both products are made of tempered steel and are plastic-coated to prevent scratching the aircraft. Future Prop Clubs may have a key option, as opposed to the current preset combination lock. — Alton K. Marsh
