Re: "Jittery" Audio Quality

The 2.5 seconds is not in the device's documentation. The D-Star echo test leads to this section of the manual "Note that only about 10 seconds can be recorded and played back by the local echo service." If it is only 2.5 then it explains the short messages; however, I've had the echo service fail m...

Re: "Jittery" Audio Quality

I have turned on the Standby Beep on the radio to make it obvious. Below is a 90 second clip with 19 drop outs. Lots of times the dropouts are associated with audio glitches - similar to what I hear on the echo test. I can quickly switch over to a local D-Star repeater, connect to the reflector and ...

Re: "Jittery" Audio Quality

I don't want to use an external Reflector Echo Test. My OS2 is not processing audio correctly and is failing every two seconds on either receive from a reflector or during an internal Echo Test. The OS2 has a built in Echo Test and if the unit is functioning properly will transmit back up to 10 seco...

Re: "Jittery" Audio Quality

Here is the audio from three Echo Tests (DStar using "_______E" directly to the OpenSpot2). https://www.dropbox.com/s/pj1nfs5pih5dsav/Echo_Test.mp3?dl=0 The first two tests are only 2 and 3 seconds each - yet the audio is clipped and only about the last second of the test is played back. The third t...

Re: "Jittery" Audio Quality

Just to follow up - I have repeated the echo test and it randomly plays 1 to 4 seconds of audio back. I believe there is a memory fault in the unit that causes this and is causing the audio to play back with the intermittent gaps (the "jitter" I am experiencing) - just like the echo test. Is this co...

Re: "Jittery" Audio Quality

The Transmitter is at 100% Power.

The echo test only records about 1 to 2 seconds of audio - not the 10 seconds as stated in the manual.

For example if I say "1 2 3 4 5 6 7 8 9 10" in about five seconds (via D-Star - "_______E") I only hear back "8 9 10" and NOT the rest of the message.

"Jittery" Audio Quality

I have read several posts about trying to improve the audio quality of the OpenSpot2; however, mine is so bad at times makes it almost impossible to listen to. The audio keeps cutting out - sometimes as often as every second or two - making it very frustrating to listen to conversations. I have disa...

Newbie D-Star Questions

I am new to D-Star and using the OpenSpot2. I have a new ICOM 5100 and OS2 that I will be setting up next week. I have watched many D-Star videos and OS2 videos plus read the manual for both devices. I have increased my understanding; however, there are a couple of gaps in my knowledge that I can’t ...
