Communication Receiver

2010 - Front View This was a design of Philips made in about 1962. It was a receiver for the Radio Amateur Shortwave bands, the 80, 40, 20, 15 1nd 10 meter bands. The size of the front is 465 mm wide and 200 mm high.

No kit

2010 - Drawing with IF and LF amplifier and powersupply It was not a kit, only the schematic diagram and the construction drawings were supplied. All components had to be bought one by one in a shop. At the right a part of the drawing. It shows the power supply and the IF and LF amplifiers. In the 2010 on the photo's the choke in the power supply was replaced by some resistors. This works fine for low current.
Also the chassis is home made from 4 mm aliminium. All holes are hand drilled and hand cutted.

2-Meter Converter

2010 - Drawing with IF and LF amplifier and powersupply Since there was some space left in the unit, it was possible to place a 2-meter converter. This small Printed Circuit Board converts the 2-meter band: 144-146 Mhz to the 10-meter band: 28-30 Mhz.
At that time the most popular modulation on 2-meter was FM modulation and the 2010 had no FM demodulator. However, the narrowband FM was very good detectable on the edge of the signal, with the so called "edge detection".
