I've received SAQ in Sormano, JN45PU, ABT 50 kM north of Milano. My rig: 1) E-field antenna (Coca Cola can + home made impedance adapter with J310 fet source follower & BFR96 transistor emitter follo
I have a Siemens data book with all data but the pot cores are 26x16 mm. If you confirm the diameter 26 I take some pictures an send you. 73 de Claudio IK2PII -- Caselle da 1GB, trasmetti allegati fi

Received your QSO with G3XDV. No trace of XDV signal. Fine Summer Solstice! 73 de Claudio IK2PII -- Z-Light e Z-Pro: servizi zimbra per caselle con dominio email.it, per tutti i dettagli Clicca qui h
SAQ received at 9.00 UTC, signal about 20dB over the noise. QTH: Milano - Italy Hardware: E-field antenna + preamplifier + PC audio board Software: Spectrum Lab Attached the start message audio file
Interesting experiment. Two sudden ideas... 1- Usually NDB are AM modulated, so you can find a continuous carrier with two keyed sidebands +- about 1000 Hz. Carrier and sidebands are phase correlated

HI Jim, TNX for Feynman URL. If you are interested also in the history of Conduction of electricity through gases I suggest this book: Thomson, J. J. (Joseph John), Sir, 1856-1940 "Conduction of ele

May be that you forgot that the electric charge in the atmosphere is carried by free electrons, positive and negative ions, so you have to take in account the speed of those particles in your model.
Yes, SpecLab can do the job. I have compared a loop antenna with the Miniwhip using SpectrumLab and switching the antennas using a toggle switch, the PC was a laptop with mono audio input. The waterf
My 20 kHz piezo antenna May be Telettra in the '69 forgot to patent this 20 kHz antenna? Or may be SLAC re-discovered the xtal (pardon LiNbO3 ) resonator? 73 de Claudio, ik2pii -- ZE-Light e ZE-Pro:
63.1 dBm - 32.1 dBm = 31.0 dB : the quartz adapted antenna radiated power is 1/1000 respect the T-Marconi, so the efficiency is 0.1% Good DX ;-) Claudio, IK2PII -- ZE-Light e ZE-Pro: servizi zimbra
