Stefan:
All EU LF BCD reception was in rural site, not in my regular QTH, (urban
zone in Neuquen city: FF51xb)
I have audio records of Europe AM Broadcast
You can download audio record in WAV and MP3 in this site:
www.qsl.net/lu8yd/LW
There are not any LF broadcast in South America, all broadcast here in MW
530-1710 KHz. Below 530 KHz only NDB aero beacon. Not time signals.
LU1DOW confirm my error in ARGO last night : +0.2 Hz, I confirm this value
receiving weak signal 153.000 Europe Broadcast 1 hour ago.
LU1DOW Oscar generate his LF signal with IC-756 at 13.777 Mhz diving for
100.
Oscar waits 2 hours for temperature stabilization before TX on.
Now Argo is calibrated in QRSS120 also with the correct offset, I use R-75
always in USB 137.000.
My station grabber is active only on request because I am NDB hunter and I
have only one Receiver and Inverted L antenna, now I am making 1.3 m x 1.3 m
square loop antenna for 137 Khz and I am waiting MFJ-1026 noise cancelling
from USA for better reception.
Now my grabber is uploading capture for all station interested in DX
capture from Argentina.( centered 137.777 QRSS120) (QTH FF51xb)

Asunto: Re: LF: Fw: Sucessful LF 137 KHz test in Argentina.
Alex,
Your QTH and RX sounds interesting! It is a real benefit not to have
mains hum near the RX!
You said you can receive EU LF BCD stations: Please, what S/N is DLF
(Deutschlandfunk) at 153 kHz (AM) and what S/N is DCF39 at 138.83 kHz?
This could become an interesting information since those stations are
located near the amateur radio LF band.
If you have SpecLab as an alternative you could monitor the levels of
those two stations over 24 hours and can show us the dayly dependency of
S/N.
Are there any LF BCD stations in Argentinia, as close as possible to 137
kHz?
I hope you will receive my signal this saturday night! :-)
Best 73, Stefan/DK7FC

Hi,
Is a pleasure to report the successful reception of the LU1DOW test
transmission in QRSS10 137 KHz past August 21.
LU1DOW station: Tx 400W Power out Antenna: 100 m inverted L. ERP: ????
grid locator: GF05rm.
LU8YD station: Icom R-75 + Argo + HP530 notebook, Antenna: 100 m Inverted
L
wire with home made tunner, two ground rods and 20 m radial for grounding,
all operated with 12 Vcc GEL battery energy system QTH: special rural
site
without human QRM without electric lines. Locator: FF50sp, distance to
LU1DOW: 1035 km.
In this site also good reception of Europe AM Broadcast in LW band.
I attached four capture images, QTR is local time (UTC- 3), see two other
UNID signals some Hz up.
