Yoonh, 

I have a '505 but have not had a chance to try this yet. I'll try your trick in the next day or two and let you know what happens.

I have decided to return my PL-505, but I'm still curious about its ability to receive between 1715-2300khz.

Is there any PL-505 user who found this working?

Thanks.

The problem is that the radio shuts off itself when reached 21950khz, not starting it over from the bottom 2300khz as MW or FM does. Is this happening on my radio only?

However, it seems like it gives me extra shortwave coverage for 1715-2300khz, though I haven't received anything from this new(?) band yet. So I'm not sure if PL-505 really works for this band.
