AEM's MTP136D covers conventional P25 Phase 1 digital and analogue VHF FM across 136-174 MHz, with USB-C profile loading, 250 zones/5,000 channels and main/guard operation through one antenna connection. MTP138 supplies analogue VHF FM at 138-174 MHz with a 3.5-inch NVIS-compatible display. NIICD's March 2026 list approves MTP136D for interagency fire use among radios it does not support. Aircraft approval remains model-specific: Canadian SH24-21 and the FAA AS350 list have different scopes, and separate MTP136D Bell approvals exclude 412EPI.

Recorded applications
Interagency aerial firefighting communications using MTP136D
Special-mission aircraft radio integration
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Commercial radios. NIICD lists MTP136D for interagency fire use, without NIICD support. AEM reports 450-plus MTP136D deliveries as of March 31, 2026. Installation approval applies to the listed aircraft and package.
Commercial availability
AEM supplies radios through its sales/dealer routes; aircraft-specific STC packages and configuration must be established for the installation.

Anodyne Electronics Manufacturing: 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.
