  Πολυ καλο μηχανημα αλα ατα μαισεα κυματα.ειναι καλητερες οι λυχνιες παραδηγμα για πομπους απο 1 εως 5W ειναι η λυχνιες EF80 EF85 και για λιγο μεγαλητερα μηχανηματα οι EF183 EF184 με ενα διοδακη BY227/BY228 και αντισταση οδηγου 22ΚΩ και αντισταση προστατευτικου 2K2 ΚΩ με της παραπανο λυχνιες μπορουμε να βγαλουμε γηρο στα 4.5W και μπορουμε να το αυξησουμε μιονοντας τα.ΚΩ στην αντισταση του οδηγου το κατοτατο 10ΚΩ. Επισης για αυξομιοση των watts μπορουμε να αυξανουμε την ανοδηκη ταση μεχρι 350V διοτι ειναι μικρες η λυχνιες αυτες π.χ μια λυχνια EL504 μπορει να αντεξει ταση μεχρι 625V οσο μεγαλητερη ανοδικη ταστη τοσο περισοτερα WATTS

  Hi there! You have probably heard about Morse code. Morse code is still used nowadays by some people. These people are radio amateur operators. Every letter in morse code is translated to dots and dashes. In order to send those dot and dashes we need a Key. That's what i am building in this video. A key is basically a switch. If you have any questions let me know. 73 thanks for watching

  @aarongriffin816 ай бұрын

  Awesome job and perfect for pota, sota, camping, etc. Can this same application be used in a delta loop? The center wire terminates back to the ground/braid. The loop can be as large as practical and then the coil will fine tune the length for each band.

• 
  @sv2tcb6 ай бұрын

  Yes perfect for outdoor activations. I have not tried a loop, i don't know if it is going to work but it is a good idea. Keep in mind that at 40m the performance is limited due to the small length of the antenna. Many 73, good luck
