Hobbyist Dream - Weller Soldering Iron

Rework/repair tools, soldering guns and irons and accessories. 60 Watts, 240v Temperature Controlled Soldering Station. This is My Iron and a stand i made.

Hobbyist Dream - Weller Soldering Iron

There’s no mystery about soldering; it’s as easy as you make it. Follow a few simple rules, and metal joins metal like magic. This little book gives you the rules in pictures—with as few words as possible. All you need do is follow through, step by step, and youll solder sound joints.

QRP and homebrew by DL2YEO

"My name is Udo and I am living in the small village called Spenge, about 15 km north of Bielefeld. The DARC radio club is 'OV Widukind - N59' and the locator is JO42FD. I spend a part of my freetime with designing circuits and home-brewing electronic devices..."

QRP and homebrew by DL2YEO 

"The electronics industry uses several methods for labelling front panels and enclosures, including screen printing, press forming, erosion, lasers etc.. The common factor of these techniques is that they are generally beyond the home constructor. Having these parts specially made commercially can be very expensive, and the only alternative is standardized scales and fonts."

“One test result is worth a thousand expert opinions”. This has been attributed to a range of people, but most authoritatively to Wernher von Braun, the rocket scientist.

A 40 dB RF Attenuator - "To measure power of a high power transmitter, or to be able to observe the output signal on an oscilloscope or spectrum analyzer, it is necessary that the signal is attenuated in accordance with the instrument, while it must be ensured that the transmitter is "seeing" the correct impedance. So it requires an attenuator that works with three ports (input, output, and output attenuated), all while maintaining the correct impedance of 50 ohms.

The circuit assembly and is shown here in EMRFD and also in the QST. When properly calibrated can be used for precision measurements in section 0-500 MHz, or a a calibration capacitor C1, can be used for the range of 0-50 MHz with reliability."
