Observation on 4193,3 KHZ
Hello radio Dr.Tim
Thanks for your email!
I am very glad you could receive my carrier over there. I have been experimenting with transmitters a lot lately and have now finally made one wich can do 0-4w. The power I was using was about 1.5w because the antenna was not tuned and would otherwise cause a lot of interference. The antenna is also homemade, a G5RV design but needs some kind of a tuner. The transmitter consists out of an audio amplifier, a (homemade) modulation transformer, a crystal oscillator, a driver and final stage (IRF510). I am continuing to experiment with different transmitter schematics and will start a real radio station from the moment i build a good transmitter. I have just made a quick qsl card for you with some pictures of my transmitter and hope you like it.
