I rarely post about it, but a few of you probably already know that I am a licensed radioamateur. Nowadays I rarely turn on my radioamateur transceiver (Yaesu FT-450D), because it consumes a lot of electricity, even on receiving. Today I transmitted two times with it in the WSPR-2 mode on 21 MHz using the WSPR Tx Android application on my smartphone (Samsung Galaxy A12).
I received nine spots.
My equipment:
Radio: Yaesu FT-450D.
Antenna: D-Original Outback-1899 mobile antenna, directly connected to the transceiver in the room of my current rent.
TX Power (during these two transmissons): 5 Watts.
The 0.01 Watt report on my first transmission is a bug of the WSPR Tx Android application. The lowest transmitting power is 5 Watts with my transceiver, so it is not possible to transmit with 0.01 Watt with it.
I reached five countries with these two transmissions:
Iceland, England, USA, Ireland, and Scotland.
The lowest covered distance is 1942 km (Scotland).
The highest covered distance is 7151 km (USA).
Not bad for an indoor mobile antenna.
The reached stations on the map:
The WSPR is an opensource project, but you need to have a valid radioamateur license for transmitting. Anyone can receive. Well. Almost. Anyone with a PC/laptop, with a radio and with an antenna. Nowadays I do not have a PC/laptop, so I cannot try the receiving on WSPR-2.
More information (including the database and the above mentioned map) about the WSPR project can be found on the official website of this project: http://www.wsprnet.org.
Thank you for reading/viewing.
Have a nice day and have a nice weekend.
All the best. Greetings and much love from Hungary.
