En este nuevo proyecto que he diseñado, es ideal para trabajar en QRP nada nuevo que no sepamos, hay mucho escrito sobre los Medidores de Estacionarias tan necesario y que no puede faltar en nuestro cuarto de chispas, también están disponibles infinidad de modelos y precios para todos los bolsillos, pero no hay nada mejor que montarlo nosotros mismos y experimentarlo, vamos a ello. El circuito que se muestra dispone de 2 instrumentos de medida y en tiempo real nos permitirá ver la onda directa y la reflejada, es ideal para utilizarlo con acopladores de antena manuales dado que resultara mas cómodo la sintonía mirando ambos instrumentos a la vez y no depender de un conmutador para ver alternativamente la directa y la reflejada con un solo instrumento. De todas formas también incluyo, para los que quieran utilizar un solo instrumento de medida el circuito eléctrico del mismo, en esta entrada los datos de construcción estarán referidos al medidor de estacionarias con 2 instrumentinos de 200 µA de sensibilidad cada uno. Si se puede decir de originalidad, el sensor que utilizo para obtener las muestras de onda directa y reflejada son varillas de una antena telescópica de un musiquero en desuso cortadas adecuadamente y de diferente diámetro, insertadas en dos soportes de baquelita como se muestran en las capturas fotográficas. El rango de funcionamiento al cual lo he probado ha sido muy amplio y con resultados excelentes de 3.5 - 430 MHz. También está calculado para aguantar vatios de potencia. Esquema eléctrico con dos instrumentos de 200 µA Como se puede apreciar el circuito es simétrico, si se invierte el sentido de RTX y ANT las medidas de los instrumentos también se han de interpretar invertidas. Esquema eléctrico con un instrumento de 200 µA El sensor esta formado por L1, L2 y L3, (L1=L3). Se utiliza un potenciómetro tandem de 2x22KΩ. En el montaje con un solo instrumento se ha de disponer de un conmutador de 2 posiciones 1 circuito para ver la directa (FWD) y la reflejada (REF) alternativamente. Detalle componentes Se ha utilizado una caja de aluminio con el objeto de constituir una "Jaula de Faraday", es decir todo el conjunto apantallado, la misma se ha mecanizado adecuadamente para contener los conectores PL, potenciómetro e instumentinos. Detalle del sensor Se pueden ver las bobinas L1, L2 y L3, en realidad son elementos longitudinales obtenidos de las varillas de una antena telescópica, soportados en dos formas de baquelita y paralelos entre ellos, no siendo criticas sus medidas. Sus medidas son: - L1, L3= 4 mm de diámetro y 6,5 cm de longitud. - L2= 6 mm de diámetro y 8 cm de longitud. - Separación entre ellas 3 mm. Detalle montaje del sensor En la foto se puede apreciar el mecanizado de la caja de aluminio y la conexión eléctrica del sensor directamente a lo que sera la entrada (lado RTX) y salida (lado ANTENA) de los conectores PL, la soldadura como se puede apreciar se realiza en la que denominamos bobina L2. Detalles conexión L1, L3 lado RTX y conexión L1, L3 lado ANTENA Vista general del montaje eléctrico y mecánico Vista frontal Vistas posteriores Vista General ¡Felices ondas estacionarias y buenos DXs!
Arduino Pinball Machine That Plays Itself!: "A pinball machine that plays itself, doesn't that take all the fun out of it?" I hear you ask. Maybe if you're not into autonomous robots it might. Me, however, I'm very much all about building robots that can do cool stuff, and this one does some …

Superregenerative receivers are characterised by their high sensitivity. The purpose of this experiment is to deter-mine whether they are also suitable for short-wave radio. Superregenerative receivers are relatively easy to build. You start by building a RF oscillator for the desired frequency. The only difference between a superregenerative receiver and an oscillator is in the base circuit. Instead of using a voltage divider, here we use a single, relatively high-resistance base resistor (100 kΩ to 1MΩ). Superregenerative oscillation occurs when the amplitude of the oscillation is sufficient to cause a strong negative charge to be applied repeatedly to the base. If the regeneration frequency is audible, adjust the values of the resistors and capacitors until it lies somewhere above 20 kHz. The optimum setting is when you hear a strong hissing sound. The subsequent audio amplifier should have a low upper cutoff frequency to strongly attenuate the regeneration signal at its output while allowing signals in the audio band to pass through. This experimental circuit uses two transistors. A Walkman headphone with two 32-Ω earphones forms a suitable output device The component values shown in the schematic diagram have proven to be suitable for the 10–20 MHz region. The coil consists of 27 turns wound on an AA battery serving as a winding form. The circuit produces a strong hissing sound, which diminishes when a station is received. The radio is so sensitive that it does not require any antenna to be connected. The tuned circuit by itself is enough to receive a large number of European stations. The circuit is usable with a supply voltage of 3 V or more, although the audio volume is greater at 9 V. One of the major advantages of a superregenerative receiver is that weak and strong stations generate the same audio level, with the only difference being in the signal to noise ratio. That makes a volume control entirely unnecessary. However, there is also a specific drawback in the short-wave bands: interference occurs fairly often if there is an adjacent station separated from the desired station by some-thing close to the regeneration frequency. The sound quality is often worse than with a simple regenerative receiver. However, this is offset by the absence of the need for manual feedback adjustment, which can be difficult.

This is 7-digit frequency meter measuring frequency from 10 Hz up to 1300 MHz. It is based on ideas of PIC16F84 based frequency meter. The measuring range is divided into two subranges: 10Hz - 25MHz and 25 MHz - 1300MHz. The decimal point is after MHz digit, but can be set at any position. It contains: * PIC 16F84 * 74HC137 (BCD -> 1 of 8 decoder) * SAB6456 VHF-UHF divider by 256 * 7-digit calculator display (common cathode), * some resistors, capacitors and 2 switching diodes
