Hi,

I'm looking for a decent quality FM receiver kit with a tuning range of approx 70-110 MHz

I've found the Ramsey "FR1C FM Broadcast Band Receiver Kit" kit:
http://www.amazon.com/Ramsey-FR1C-B...1?ie=UTF8&s=electronics&qid=1286799172&sr=1-1

I purchased their shortwave receiver kit and it was quite decent. Does anyone have any opinion about this kit, or where can I find a decent kit?

 

Hello,


It is hard to say anything about the quality without a schematic or info on the used IC's.


Take a look at this kit from ELV, a german firm:
http://www.box73.de/catalog/product_info.php?cPath=112_115&products_id=1936

I used google for the translation of the text:

Kit for a RDS radio module with integrated stereo amplifier and with an interface for communication with PC or microcontroller.
The radio module is based on a microcontroller-controlled PLL receiver chip that also handles the RDS decoding. This allows the construction take place completely adjustment-free and there are by the microcontroller control many features available, found elsewhere only in high-quality car radio or stationary receivers sind.Durch the extremely compact design, the possible Abteilbarkeit the keypad board and the possibility of remote control and the FS20-channel system of ELV is the radio module extremely flexible. It can find, for example, both in a wall panel and in the boat cockpit or in a portable device into place. The very shallow mounting depth allows installation in tight spaces. A jack even allows the connection of an external stereo audio source such as an MP3 player.

Technical data:
Frequency Range: 87,5-108,0 MHz
Vote: automatic scanning (sensitivity adjustable)
Display: backlit graphics display (2 x 16 characters)
Radio Data System (RDS): various display modes such as radio text possible
Operation: 8 buttons (optional detachable and replaceable by any keys)
Remote Control: Optional (868 MHz, FS20-compatible)
Interface: Optional USB module connectable (FS20-compatible)
Amp: Stereo, 2 x 1 W into 8 ohms available on board
External audio input: any stereo signal source, such as MP3 player
Other features: signal level display, stereo / mono switch, station presets
Power supply: DC jack, 8-12 V DC
Dimensions: 67 x 37.5 mm display board, main board 69 x 29.5 mm, keyboard unit 67 x 26.4 mm

Hi Bertus,

This is the link to the Ramsey kit documentation:
http://www.ramseyelectronics.com/downloads/manuals/FR1.pdf

Unfortunately they omitted the circuit diagram!

I looked at the link you posted - looks very good, but I am interested in building a circuit with manual tuning, not automatic scanning.

It seems that you don't seem to get the variety of kits you did in the 60's and 70's - what a pity.

 

Hello All

This kit is not bad, we used them in a college class.
