I have a solution for this now (thanks to Andrew Weekes for the pointers).
It looks like the signal is actually being picked up by the headphone cable (not internally). It goes into the 1/8" jack and then gets amplified back out by the headphone amp. The behavior seems different depending on the type of phones - Sennheiser HD 600 phones only exhibit the problem if the cable is actually wrapped around the antenna, whereas Sony MDR-7506 picks up the signal easily. YMMV. Anyway, the fix is pretty simple but it does require soldering: attach two 33pF caps to ground on the headphone jack - make sure to keep the leads as short as possible - surface mount caps are best. This eliminates the problem for my test case, irrespective of antenna arrangement etc. If you're comfortable doing this yourself, I've posted some step-by-step instructions here: http://www.seanadams.com/sb2_headphone/ Otherwise please contact [EMAIL PROTECTED] if you want to have the repair done by us. -- seanadams _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
