The FR has signaficantly better signal when held out of the window.=20 When holding out of the window during a call, it takes a short moment then buzzing disappears quite suddenly. Going back into the room again after a moment the buzzing returns suddenly. So it comes and goes in discrete steps and it lags behind the change of position. BTW: Not that I would know anything about these things. But would it be possible to lower the TX-power of the FR to see how far down you can go without loosing connection?=20 I have active speakers in my room that catch GSM signals. I noticed several times that the noise in the speakers when the phone is registering is louder with the FR than with a Motorola V3x with the same SIM. --adJ1OR3c6QgCpb/j Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkiYXlMACgkQS1FjE303ERzsLwCfZyGK2WWLAr4yLsoyPLHfncIg ncEAoI9U5Bylp1krTVHANneJM8yU+RT9 =ZXjk -----END PGP SIGNATURE----- --adJ1OR3c6QgCpb/j-- --===============0610733123== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support --===============0610733123==-- ]
