An attenuation vs. VCONT plot could tell us how close to the abyss we are with the voltage levels we have there. But we can leave this task probably to the hardware team in Taipei. > Right, no I didn't put the shield back.

From the GPS debugging efforts I saw in HXD8, I would expect GPS to resent a lack of shielding rather heavily. By the way, the antenna switch circuit is identical to what we used in GTA01. I wonder if anyone noticed usually bad sensitivity there ? - Werner _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
