The AA7B is an antenna amplifier which will amplify radio frequency signals (HF, VHF, UHF). I'll use the AA7B with the SR2C in a future post for demonstration. The AA7B is connected by coaxial cable to the receiver. In addition, the AA7B can be powered by a 9V internal battery of external power supply. The AA7B is for boosting reception only; transmitting RF into the AA7B will damage the unit.
This blog will keep to a simple theme of my tinkering with electronic and computer related toys, gadgets, projects and the like. I do hope from time to time there is something for someone to find when they are exploring these things for themselves. From an early age, I was always attracted to electronic gadgets an I continue to enjoy myself with my hobby. Unfortunately with a busy life, time becomes short an I can not indulge myself like in the past.

Ramsey's SR2C a 4-19.5 MHz Shortwave Radio
The Ramsey's SR2C is a single-conversion superheterodyne receiver designed for listening to AM broadcasting stations in the range of 4-19.5 MHZ. The SR2C does not come with an antenna or external speaker. In a future post, I will demonstrate the SRC2.

1 watt Mono Power Amplifier
This is Kit 27 from Kitsrus a 1 Watt Mono Power (audio) Amplifier featuring Philips integrated circuit TDA 7052. I built this kit to modify a shortwave radio that will be featured in a future post the Ramsey's SR2C. This amplifier uses a 6-12 volt direct current power supply to drive up to a 8 ohms speaker. In the picture, I have a 8 ohm speaker, a 12VDC battery pack, and a mono plug attached; these items are add-ons and do not come with the kit.

Dale Wheat's Infrared Spotlight
This is an Infrared Spotlight on a 6x6 printed circuit board using six 100 ohm resistors and 36 IR light emitting diodes. The Spotlight requires a 12 VDC power-supply. In the pictures and video, the Spotlight did not illuminate or allow my camera to work in the dark, in other words, see in the dark . The Infrared Spotlight did seem to compliment my night owl scope with out using the scopes built-in IR. When I get the 12 volt battery pack, I can do a better assessment out of my work shop since I am tethered to my power supply currently. Some possible uses is as an IR-beckon, a complement to an IR-enabled device, or, possibly IR for a robot, but with the addition of IR light detectors.
