Ground Optimum radial wire length vs. number of ground radials Optimum radial wire length vs. number of ground radials for quarter wave vertical antenna Electrical grounding Antennas By N6LF: Are the lengths of radials related to the height of a vertical? I first posted this note some weeks ago with information on the relation between vertical height and radial lengths. However, that information was buried in one of the attachments.

ADE-1.pdf (application/pdf Object) Parts Search Supplyframe.com NE602 602 mixer The NE602 is a low-power VHF monolithic double-balanced mixer with input amplifier, on-board oscillator, and voltage regulator. It is intended for high performance, low power communication systems. The guaranteed parameters of the SA602A make this device particularly well suited for cellular radio applications. The mixer is a Gilbert cell multiplier configuration which typically provides 18dB of gain at 45MHz. The oscillator will operate to 200MHz. It can be configured as a crystal oscillator, a tuned tank oscillator, or a buffer for an external LO. For higher frequencies the LO input may be externally driven. The noise figure at 45MHz is typically less than 5dB. The gain, intercept performance, low-power and noise characteristics make the SA602A a superior choice for high-performance battery operated 602 mixer data sheet Tubes Tube Preparation Jeff Duntemann's Homebrew Radio Gallery A photo gallery of home-built radio gear by Jeff Duntemann K7JPD.

It comes in a single or dual package and even low power cmos versions exist - ICM7555. Common part numbers are LM555, NE555, LM556, NE556. The 555 timer consists of two voltage comparators, a bi-stable flip flop, a discharge transistor, and a resistor divider network.
