Looks like a spurious response caused by your oscillator's third harmonic
and the radio's poor RF selectivity.

Assuming an IF frequency of 455 kHz, when the radio is tuned to 1615 the
local oscillator is running at 2070 kHz (1615 + 455).

The third harmonic of 2070 kHz is 6210 kHz.

With an IF of 455 kHz and an oscillator frequency of 6210 kHz, there will
be
a response at both 6665 kHz (6210 + 455) and 5755 kHz (6210 - 455).

KAIJ carries Dr. Scott on 5755.

I just told someone over in rec.radio.amateur.dx that I'm
ready to mail my Grundig back to China with a letter enclosed telling them
where they can send it from there. This whole shortwave/AM DX experience
has been extremely frustrating.

All I want to do is turn on my radio, spin the dial until I find something
interesting, look it up in my "Passport" book and have that be the end of
it. sigh Oh well. I might as well start wishing for world peace.

You might try checking your radio's local oscillator output with another
radio. I'll bet it puts out a receivable signal at 6210 kHz as you tune
around 1615 kHz.

The first part of that went clean over my head. Thanks for trying, though!

FWIW I'm using a Grundig S350, grounded, with a 75' random wire antenna.


And for rec.radio.shortwave, does anybody know of a URL that explains
the

process by which SW trasmissions are rebroadcast via satellite?
Obviously,
I've got more to learn about this.

I'm still looking for this one. Part of the fun of this, which I didn't
include in my rant above, is how I'm sharing this with my kids. I've got a
big map on the wall, and we stick pins in the places where broadcasts we've
received originated from. But as you all know, you can't always tell where a
signal is coming from what with relays and satellites, etc. I'll just
persevere. I'm going to enjoy this damned hobby if it kills me.

It's a great hobby. Always something going on.
