The 4040 is a twelve stage binary counter in a 16 pin package. The 4060 is a fourteen stage binary counter and oscillator, in the same 16 pin package.
The 74HC or 74HCT versions of these chips may be used for a higher frequency range, but the supply voltage range is then limited to a maximum of 5.5 volts or so.
In order to use this in order to display the frequency of a typical HAM transmitter, some sort of a prescaler and a preamplifier will be needed. Hopefully these shall be the subject of a subsequent instructable.
Step 1: Twelve LED array
The first step was to wire the counter and make it work. I rounded up a number of red 3mm leds from my junk box and various boards and soldered them up in line on a sliver of circuit board - the result is shown here next to the counter chip. This particular ic was extracted from another half-finished project, with the fervent hope that at least this one will end up finished.
The 74HC4040 will be a better choice if you are planning on building this. It can count to a higher frequency.
