Semiconductors:

Q2 = 2N2369, 2N2222, NTE123A, NPN transistor
L1 = 1mm enamelled copper wire on a 10mm body (no value specified)
	 
Notes:
Q1 and Q2 both reference to a NTE123A replacement type.

With a short antenna the maximum distance is about 600 feet (200M).  But with a proper antenna this distance can easily 
be changed to about 1/2 mile (800M)!  Even so, keep in mind that this simple transmitter is just that; simple!
If you find that the frequency drift a little, secure the coil with candle wax or a dab of hot-melt glue.



Coil L1 is wound on a 10mm body.  Use a wooden dowel or similar.  Wind about 4 turns of 1mm enameled copper wire 
(also called 'magnet wire') on a 10mm body.  Obviously, remove the body after winding.  
Scrape the enamel off both ends of the coil before attempting to solder.

As for the ceramic capacitors, try to find and use the socalled 'NP0' types for low noise/temperature drift.  They 
have a black stripe at the top of the cap.  They are manufactured by Philips.

The variable capacitors, C3 and C6, are just the regular trimmer caps.
This type of transmitter works best in a metal enclosure.  Just make sure nothing of your circuit is touching it.

"Gnd." in the schematic diagram just refers to the negative pole of your battery.
