Crystal Radio Litz Wire Contra Wound Coils at makearadio.com
Contra coils are my favorite radio coils. They can be wound as a spider coil as shown in this article or can be wound as a cylinder coil. The main advantage is that the resultant Q at the high end of the medium wave band is better than a regular wound coil. This improves the selectivity at the high end of the band.

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. To make it easier to find I've extracted the parts relevant...

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

555 timer
The 555 timer is one of the most remarkable integrated circuits ever developed. 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. The 555 timer is ideal for astable free running oscillators as

A Smarter Approach to Resolving Power-Line Noise
Although the problem has been around since the dawn of radio communications and broadcasting, power-line noise issues are A on the rise. The proliferation of electrical, electronic, mobile and wireless devices which are susceptible to power-line noise have contributed to this increase. The law requires utilities to rectify power-line interference, but this does not have to be a budget-breaking experience.
