This is a Sole Source (Including Brand Name) Justification document for simplified procedures for certain commercial items. The document justifies a firm-fixed-price sole source purchase order for Quasonix telemetry transmitters and receivers to support flight test activities at Edwards Air Force Base under the 420th Combined Test Force. The contracting officer is Susana Dryer at AFTC/PZZF, with approval dated May 6, 2026. The estimated contract cost falls within the >$AT and <$750K funding level, and the purchase request number is F1S0AY6104A002.

The requirement includes five specific line items of Quasonix equipment: a single-channel compact receiver (QSX-RDMS-1C37-QO-1111-04-14-EQ-ET), a maximum likelihood stream combiner (QSX-MLSC-12-IP2), five fan-cooled heat sinks (QSX-AC-34-HS-28V-SP), five L/S/C-band telemetry dual STC transmitters (QSX-VQR8-1110-10-64-24AL-C7-DP-HR-LD6-STC), and three dual-channel 1U rack receivers (QSX-RDMS-3R1D-E1-1111-00-14-CS-EQ). The justification demonstrates that Quasonix is the only vendor capable of meeting the specific technical requirements due to the transmitter interface and frequency transmission characteristics required for the current mechanical and electrical design. Market research confirmed no suitable alternate part numbers or authorized resellers besides Elotek and AeroGear. The document certifies that fair and reasonable pricing will be determined per IAW RFO 13.106-3, with comparison to previous purchases and market research conducted through GSA, Internet websites, and federal supply schedules.
