[amsat-bb] TR-751

[Szegedy]

Dear friend!


I like to ask you:

If my Kenwood TR-751 is in scanning mode I hear impulse noise(about in every 0.1 second) from speaker if I near the speaker(5cm) or use a headphone if volume is 12clock position.
Can you check it with other TR-751?
What cause this problem?
Other people doesnt have this problem with TR-751.
I realised that if I rotate the main dial I hear also this sound .Why?


Thanks
