🔘I was particularly active transmitting on the LF ∿136KHz/2190m long-wave 📻radio band during 📅February. My radio transmissions on that band have now paused until I resume them once again later in the year when the long nights return.
My transmitter ⚡is home made to my own design. The output power is 150 watts. My🗼 antenna consists of vertical sections of aluminium tube totalling 📏14m long to the top of which is connected a wire which extends horizontally for 📏47m. Two loading coils➿➰are also connected; one ➿at the base of the vertical section and the other ➰to the far end of the wire. Both the 🗼antenna & transmitter have been featured in several previous posts.
The modes which I predominantly used were the 32 minute ⏳beacon mode called "Opera32", and the slow morse modes known as "DFCW10" ( Dual Frequency CW with 🕑10 second dashes ) and "QRSS4" ( 🕑4 second dots ).
My transmissions were reliably received 🎧by the 📻receiving station ( 'grabber' ) of DL0AO near Amburg in Germany at a distance of 700 kilometres. The signals being received can be viewed 🔗online in near real-time, from which I made the screen-shots below. Additionally my Opera-32 signal was at various times also received in 🗺 Greece, Croatia, Norway, Russia & Sweden.
