Hello Stefan,
I'm very happy to my first positive rx test on 137
KHz, i have received clear and audible signal of
DB6NT on qrss3 and IK1HSS on DFCW, Annex the
two Argo images.
The antenna is my 80M fullsize delta loop and is
not matched to the receiver but i can receive DFC39 at 138,83
at -65 dBm on daylight. In next day i try to
install a matched inverted L on my 25 meter tower (that you can see on qrz.com)
with top wire about 30 meter long. The tower is
grounded and i have ready to install 120 buried radial between 15 yo 40 meter
long
around the tower ( i want use the tower as a
vertical for 160m).
My locator is JN54SM about 15 Km north east from
Bologna.
I am not ready to transmit at the moment but i hope
to will be ready in next month. I'm making in the short time that i have
available
a linear transverter and i want use an audio
amplifier to obtain the necessary power.
The only doubt that i have is how to match the
audio amplifier to the antenna, i have not found literature.
Now i want continue to improve my receiving
equipement with new matched antenna and a good low pass filter at the input of
the
receiver (i have a local 567 KHz 25 KW
transmitter about 4 Km to my home and the level of it at the input of my Perseus
is +10dBm !!!
you can imagine the hard work for the unfortunate
input stage of the receiver...).

Dear Fausto,
Congratulations to your first
reception!
Who is the received station? How do you match the antenna to
the RX?
What is your locator and will you transmit on 137 kHz too?
