[DX] 1629 Russia/Kaliningrad

["Jari Savolainen" <jari.savolainen@xxxxxxxxxxx>]

Tuosta 1629 asemasta oli muistaakseni keskustelua täällä
joku aika sitten. Sattui silmääni tämä DXLD-juttu, jossa on
selitetty ilmiön matematiikka. JSA

KALININGRAD. Just IDed that unID from 1629 I have heard a lot in
recent months. Usually weak, but regularly there around the 1600/ 1700
time frame. Thought it sounded eastern, but found a // SW 7300. It
seems to be V. of Russia in German, sounding like Radio Moscow type
mic. How do they do that, I wonder?? Is this a real outlet or
something of a mixing product at the transmitter site? Bang on 1629.0,
as best as I can measure anyway. Messing around with frequencies for
VOR in the 2005 WRTH, brings up no mixing products on 1629. Heard on 2
separate receivers and separate aerials. There is a 2nd option. Maybe
some kind of a relay from somewhere else, authorised / unauthorised

Hi Ken, it`s a mixing product from Kaliningrad. I can't remember the
math but it involves 1386 and either 1143 or 1215. Have a look in the
archives of my harmonics group at Yahoo ;-) All the best (Tim
Bucknall, ibid.)

That would be a leapfrog from 1143 over 1386 to 1629 (gh, DXLD)

2x 1386) - (1x 1143) = 1629 3rd order intermodulation at the
transmitter. If you listen to 1629 carefully you should hear two
different streams of audio - modulation from each of 1386 and 1143
kHz. 73 (Steve Whitt, MWC via DXLD) Another way of putting it
