About this file
This is a Question and Answer (Q&A) document dated 11 August 2026 clarifying technical requirements for CLIN 0001 of a federal contract opportunity related to P25 Phase 2 Trunking communications equipment.
The document addresses three key technical inquiries regarding transmit power, modulation, and emission code specifications. The government confirms that 50mW minimum power output is a hard requirement for CLIN 0001, which allows mission-based power adjustment for lower emissions when necessary, and rejects the proposed alternative of 250mW minimum. Regarding modulation, the government clarifies that 8PSK digital phase shift key modulation is required for Trunking system operation, while 16QAM is optional and enables faster, denser transmissions but is not mandatory. The contract supports two distinct platforms with specific emission designators: BST35 requires digital 20K0D7W and analog 11K2F3E, while MP50 requires digital 20K0D7W, analog 20K0F3E, and GPS 16K0G1D. The emission codes support various functions including AES256-encrypted digital talk group communications (20K0D7W), emergency GPS beaconing and AIS dissemination (16K0G1D), UHF Search and Rescue communications (20K0F3E), and standard narrowband FM VHF/UHF capability (11K2F3E).

QUESTION AND ANSWER (QA), dated 11AUG2026
1. CLIN 0001 specifies a transmit power of 400mW configurable to 50mW. Can you confirm whether the 50mW minimum power output is a hard requirement, or whether a minimum configurable output of 250mW would be acceptable?
50mW is a hard requirement. This allows us to adjust for the mission set to lower the power, if necessary, if we require lower emission.
2. CLIN 0001 specifies modulation 8PSK/16QAM. Can you confirm the required emission designators or whether this requirement is specific to P25 Phase 2 Trunking operation?
The digital phase shift key modulation allows for the use of the Trunking system. QAM is not a requirement, but it allows for faster more dense transmissions.
3. Is this for a P25 Phase 2 Trunking application? Can you tell us what emission codes it needs to support?
Yes.
BST35 uses digital 20K0D7W and analog 11K2F3E MP50 uses digital 20K0D7W and analog 20K0F3E and GPS 16K0G1D 20K0D7W – Allows for digital talk groups communication encrypted with
AES256
16K0G1D – Allows for emergency GPS beaconing and dissemination through AIS 20K0F3E – UHF to allow comms through Search and Rescue 11K2F3E – Standard narrow band FM VHF/UHF
