Hello everyone, another new guy here. So I got this receiver as my first shortwave receiver. I have been playing around with it for at least 2 months. But it has some problems. I have read this thread and I don't see any solutions here so I will ask instead.
The first problem is that longwave doesn't work. Well it does work but it's almost deaf in that area. I barely hear any NDBs nor any broadcasters. There are several longwave broadcasters that I should be able to pick up when I've tried with other receivers. However with the S750 it needs to be very late at night, at least 23 hours local time (11 PM) or later to hear anything. But mediumwave works fine, I think.
The second problem I'm having is when I use the tuning knob there's sometimes a very annoying "drrr-drrrrr-drrrrrr" like sound, I'm not sure how to describe it. But there's also a normal sound when you're tuning and that's fine, the other isn't.
Thirdly it doesn't seem to work well with a random wire? I have a piece of around 4-meters of wire with an alligator clip to attach to a telescopic antenna as my "external" antenna. I also recently, something like 3 weeks ago, bought a Sony ICF-SW7600GR receiver and the wire seems to perform "as advertised" on that radio.
Air band seems to work ok.
Also the radio is way too loud for my liking. My ears hurt every time I've been using this radio and suddenly there's a REALLY LOUD NOISE BLOWING MY EARS OFF! When that happens sometimes I've had to turn off the radio and then turn down the volume. I'm afraid to damage my hearing this way.
The unit I bought was a used one, it may be because it's a used model it's having these problems. I bought this unit during August, when there's still was the heatwave and high temperatures.
But I'm very happy with the Sony.
