did you record sound in a room or at field? I hear classic 'windows sounds' on a start.

yes, i record in room and u are right , and from second 8 to 15, u can hear the hsss very well, in the tm808 this hssss is normal or not???

[kt315]

it's strange for me you record the sound in conditions of strong EMF (electro-magnetic fields) around. can you record the sound far away from your home, streets, electric power lines, computers, TV sets, these real idiotic 'energy saving lamps', mobile phone transfer towers, on your clear-analog tape recorder? (not these kinda 'digitally-yours' blue ray, mobile phone, i-phone, laptop, etc)

wish you success

the sound may be go from TX antenn/coil, try to reef out screwing more stringly there. some people are suggesting to weld them out in all.
