Re: [ondalarga] esquema de la Mini Whip

[Jose Manuel]

Hola   Gracias por la información Eduardo, si me decido a montarla ya os contaré, aunque en principio no creo que sea tan inmune a productos de IMD el J310 como el CP666, que es el que utiliza el proyecto AMRAD.     Saludos....José Manuel, EA1PX         ----- Original Message ----- From: Eduardo EA3GHS To: ondalarga@yahoogroups.com Sent: Monday, April 10, 2006 8:25 AM Subject: [ondalarga] esquema de la Mini Whip (tomado de la lista inglesa) jose manuel, la varilla receptora no ha de ser larga para evitar que los transistores se saturen. He leido que se ha llegado a usar la propia caja envolvente metalica como antena. Tambien se ha de montar alejada de fuentes de ruido... si la montas, me gustaria conocer tus resultados. salud eduardo ---------- Forwarded message ---------- From: Alberto di Bene < [EMAIL PROTECTED]> Date: Feb 7, 2006 1:43 AM Subject: LF: Re:  Mini Whip and local noise To: [EMAIL PROTECTED] I have simulated the mini whip with PSpice, and the results are quite good. In the schematic below, the V3 source and the 10pF capacitor simulate the whip itself. Total current from the power supply is abt 50mA, of which 38 flow in the 2N5109 and 12 in the J310. The Bode plot shows the frequency response of the output referred to the V3 source signal. The vertical scale are dB. The second Bode plot is just the LF section expanded. I have one almost built and in the next days it will find its way toward a chimney on my roof... 73  Alberto  I2PHD SPONSORED LINKS Electrical engineering degree online Electrical engineering degree Electrical engineering Electrical engineering course Electrical engineering graduate school Online electrical engineering course YAHOO!
