Amateur Radio DMR Has Come To Maine With The Augusta Maine c-Bridge

7/15/2016 ...    We have Two New Talk-Groups       NETAC1     TG 8801     and     NETAC2     TG 8802
These are both NewEngland only TAC channels, TAC 1 & TAC 2 .          
See the TalkGroup Page for more info  

      Note: Wednesday (5/25/2016) NH SW is now PTT activated for Some Repeaters on the Augusta C-Bridge..     

Note: Please remember DMR System is not like a analog repeater system, with multiple talk-groups you must leave a 5 to 10 second pause between transmissions so other people can brake away to another talk-group on another repeater in the system, or join in your conversation.
To put it in plain language, you could be tying up the time slot on the entire system if you do not leave a pause between transmissions.

Note To: Users of DMR

We encourage new users to visit the VU meter at http://norcaldmr.org/listen-now/
You will need a Chrome browser and you will need to transmit on the Audio Test talk group 9999.

Some users are really loud, Others are low. Some radios like the Tytera MD-380 and the CS700 have no audio adjustment and the operator will have to get used to a distance from the microphone.
On some MD-380 radios you may have to back off the microphone. CS700 get closer without being breathy...or send it in for the upgrade.

CS750/CS751 CS800/CS801 has ability for the user to change the microphone gain. Use the VU meter, to customize your microphone audio to fit your operating preference.

Motorola Radio, Users, Please see this page 'Audio Calibration', at http://www.dmr-marc.net/FAQ/audio.html

The eventual outcome will be a well balanced network, requiring less diving for the volume control. If there is complaint about DMR, it is the lack of RX AGC (automatic gain control), plus the lack of an audio level standard in the DMR Specifications.
The VU meter is the best we can do to help us for now!
