A closer look at the products, services, operating features, and documented applications that shape the organization’s role.
Aircraft communications equipment
MTP136D and MTP138 aircraft mission radios
What it enables
AEM supplies panel-mounted radios for special-mission aircraft. The MTP136D supports P25 digital and analogue communications across 136–174 MHz; the MTP138 serves analogue VHF FM channels from 138–174 MHz. AEM describes both as pin-compatible replacements for legacy equipment. The March 2026 SH24-21 extension adds Bell 206/407 installation coverage alongside listed AS350 variants. Applicability still depends on the aircraft model and approved installation configuration.
