The CD drive is a sturdy unit designed for the aviation environment. It plays only a single disk, but if you create your own MP3 disks, you can fit more than 250 songs on a single disk. The AM/FM receiver is designed and certified to not interfere with the VOR/LOC frequencies-not an easy task for FM-and has special logic that helps it discriminate between broadcast signals on the same frequency. At altitude an AM/FM radio receives competing broadcast signals because frequencies are assigned based on the receiver being on the ground. That means in the airplane you can get overlapping signals on the same frequency, which jumbles the signals together. The PXE7300 identifies the strongest signal and rejects any others on the same frequency, so you hear only one radio station at a time. Another airplane-owner-friendly feature is that no external antenna is required. A thin "strip" antenna can be mounted inside any cabin window, where it is out of the way and probably out of view while still providing excellent AM/FM reception.
The PXE7300 is priced at $1,495 complete and ready for installation. For more information, call 865/988-9800 or check out www.psengineering.com.
