The buzz seems to be proportional to the transmit power which itself seems to be proportional to the reception quality I can monitor with mdbus -s org.freesmartphone.frameworkd /org/freesmartphone/GSM/Device org.freesmartphone.GSM.Debug.DebugCommand "AT+CSQ\r\n"|tr "'" '\n'|grep ^\+CSQ:|cut -d, -f1|cut -d' ' -f2 According to specs these units are # 0 -113 dBm or less # 1 -111 dBm # 2...30 -109... -53 dBm # 31 -51 dBm or greater # 99 not known or not detectable and when it is around 26 or more the recipient does not hear the buzz here anymore. Thus, to mitigate the effect I can monitor the reception quality during call and align myself so that the quality is as high as possible (just going near a window helps a lot). _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
