DCI/TRBO-6 (Comm 1) and DMR-MARC (Slot 1) are available on both uStream (our primary service now) and on Radio Reference.  Comm 1 has the priority except for most DMR Nets held on Saturdays at 1700 GMT (archives available).  Net archives are available also for both RR and uStream (hit and miss effort).

FYI:  For the Ker-Chunkers out there...there is a delay from live TRBO audio to actual uStream  output of a few seconds but Radio Reference is typically about 30 seconds but has been as short as 15 seconds or as long as 9 minutes. 

The audio levels are fully conditioned to compensate for the many TRBO radios with hot audio (piercing local audio at times) which overdrives the streaming feeds.  The audio are set to pass 300-3000 Hz at 0 dB, audio above and below is attenuated 12 dB and then all audio above 0 dB is compressed 3:1.  With 8 dB of headroom locally, this limits +9 dB TRBO audio levels to just +3 dB, well below the limit of the streaming servers.  This hopefully will provide excellent audio whether listening on a high fidelity audio system or the crummy speakers in smart phones.  See our AGC audio test page for more info.

If you wish to listen via your smart phone, iPad, Tablet, etc, you can go to this mobile feed with your browser or get an Adroid app like Scanner Radio.  ustream has an Android app but we have not had sucess in it's use.  More info will be posted as apps are tested or recommended.  Comments welcome from users of other smart phones, pads or tablets.

uStream broadcasts DCI/TRBO-6 and DMR-MARC with priority to Comm 1 while scanning both networks.  uStream is the better service as it provides video of a TRBO radios' display which is rather cool as you can watch the talkgroups, user ID's, RF and Scan activity as well as hear very good audio.  The downside is that 30 second commercial as inserted randomly.  Take a look/listen: uStream of DCI/TRBO-6 & DMR-MARC 1.  It is problematic for DCI to continue with uStream video due to our limited uplink bandwidth.   We would encourage others to take up this task to stream DCI/TRBO-6 and/or DMR-MARC as it would benefit the ham community generally.  Inquire within if interested on how we have attacked this streaming project.

No changes are anticipated to the current DCI/TRBO-6 TRBO-Link portal with the existing EchoLink implementation.  Normal TRBO-Link activity will continue.

LEGACY:  As of 12-11-2011, DCI began feeding "Comm 1" and  DMR-MARC's "Goup 1" via scan on a single control radio. As soon as the second control radio comes online, the audio will be split so that the left channel will be "Comm 1" traffic and the right channel will be "Group 1" traffic.  Both will be available simultaneously with equal or no priority.

This initial streaming implementation requires a single TRBO control radio that scans both Talkgroups; "Comm 1" and "Group 1".  "Comm 1" has the priority over "Group 1" and the feed is monaural.  This is temporary until a second control radio is available to dedicate to this streaming project's right audio channel.  The initial audio rumble has been cleaned up and the base response reduced.  The audio level into the RR server is set fairly low due to the wide dynamic range and many TRBO radios that are overdriven by their operators.
