Hi Eric, Never been reported as far as I know. I just tried a few tests on a SM1000 I have in front of me. In each test I'm replaying 120 seconds of this mornings broadcast to the SM1000 from a laptop:
i) Stock firmware from factory. Played 120s no problem. ii) Reflashed using stock sm1000.bin firmware from link on sm1000 page. Played 120s no problem. iii) Latest sm1000.bin. This includes the menu system Stuart developed late last year, some recent patches, lots development of (non sm100 specific) FreeDV over the last year or so. Towards the end of a 120s session I'm occasionally hearing a problem very similar to what you report, e.g. garbled speech and errors and then recovers after 20s or so. iv) Back to stock firmware, Played 120s x 3 - no problems. So looks like it's not yr hardware. Tricky one to track down, as it takes so long to occur (at least for me). Guess a first step would be back track to earlier versions of SVN, find out if it's sm1000 specific, or if it also occurs on x86 versions. Might be interesting to monitor the free cpu cycles, stack, or try to trap the problem in some way. Can anyone else repeat this problem on their sm1000 with any version of firmware? Best to test with a wave file played from a PC, rather than an off-air signal. Thanks for the report, David On 11/09/16 16:55, [email protected] wrote: > Ok, > > Slightly modified SM1000 code.
