About this file
This file is a Questions and Answers (Q&A) document for a Request for Information (RFI) regarding American Forces Network (AFN) Europe radio connectivity. The Department of the Air Force's Defense Media Activity (DMA) is seeking solutions to deliver stereo audio programming ("The Eagle" service) to remote, isolated FM transmitter sites in Europe after their current Direct-to-Home (DTH) satellite service is discontinued in March 2026. The RFI explores potential technologies for audio delivery, with specific technical requirements including audio types (AES3, analog stereo), secure encrypted connections, and potential source pickup locations in Riverside, California, Fort Meade, Maryland, or via internet streaming.
Key technical challenges include delivering audio to highly isolated transmitter sites with no existing internet or cellular connectivity. The preferred solutions would involve either satellite transmission or establishing commercial internet connectivity that allows secure audio streaming using government-furnished equipment (GFE) audio codecs like the Tieline TLR6200-4W. The RFI is explicitly seeking industry input on two primary questions: how to deliver stereo audio to remote European locations and how to provide commercial internet via satellite to these sites. While remote monitoring is not a current requirement, DMA would be interested in such capabilities if a solution providing sufficient bandwidth could be developed.

Q&A
| Question # | Question | Answer |
| 1 | Can you please provide the required Audio types? (e.g. MPEG, AC3, AAC, DTC, Etc.) | One of the following: |
a) Sufficient Internet bandwidth so DMA can use a GFE Tieline TLR6200-4W audio codec passing ~256kbps audio stream (preferred),
b) AES3 (48 kHz or 44.1 kHz), or
c) Stereo analog audio.
| 2 | Is Encryption required or preferred? | Connection should be secure and encrypted to prevent unauthorized parties from disrupting AFN's audio streams (adversarial actors/nations/states to US interests). If DMA is using GFE audio codecs, DMA will encrypt those streams. |
| 3 | Is there a required or preferred source pickup location? (e.g. March AFB, Usingen, etc.) | Depends upon timeline for DMA transition activities: |
a) DMA Riverside - AFN Broadcast Center (adjacent to March ARB) (current)
b) DMA Headquarters - Fort Meade, MD, (MP expects to transition to Ft. Meade in late 2026 or in 2027) or
c) Stream from a DMA facility via Internet with GFE audio codec to AFN Europe transmitter site.
| 4 | Do all the remote sites where the radio channels are inserted into the local transmitter have reliable internet connectivity and space for a 1RU decoding device that would allow the reception of an Internet based secure audio stream? | No. Identified sites are isolated from both DoD and commercial connectivity of any form (including cellular/LTE) – envision a small shack in some farmer’s field out in the middle of nowhere. This RFI is focused on exploring alternate options for delivering the AFN audio programming to the isolated site via satellite – whether it be TVRO or or commercial Internet. If Internet connectivity was available, DMA would use GFE audio codecs like the Tieline TLR6200-4W. |
| 5 | What are the various ways that high quality and reliable feeds of The Eagle stereo audio can be received and be used as the source feed that would then be re-distributed to these European locations? Is it available via multiple paths so that there would be a primary and backup feed available for re-distribution? For instance, is it available as a reliable stream on the Internet, Satellite downlink, and/or other methods? | This very question is what this RFI is asking of industry. One of two questions: |
a) How would industry deliver stereo audio to an isolated remote location in Europe if handed the AFN Eagle programming from a CONUS facility?
b) How would industry provide commercial Internet via satellite to the remote location? Once reliable Internet access was available, DMA would use GFE audio codecs like the Tieline TLR6200-4W to pass the AFN Eagle audio securely to the remote location in Europe.
c) Redundancy is already handled on an alternate satellite path.
6 Is there any data, available remotely and securely via the Internet, to provide a feedback loop to the provider on the status of the remote transmitters? -- For instance, data that shows the transmitter site has power, is on-line, and that the transmitter has a valid input and is healthy. No. There is no site condition or equipment status data available from the isolated transmitter site. If the selected industry solution was able to provide commercial Internet via satellite to the remote location that had sufficient bandwidth after delivery of the AFN Eagle programming, DMA would likely explore a secure method for control and monitoring of the site. However, remote control and monitoring is not a requirement for this RFI.
