 This is the BS2 with the above circuit added. |
 This is a close up of the Above circuit. The yellow wires go the the key port on the rig. |
I also added a LED that flashes evey time the Rig is keyed . That way I know what the stamp is doing. PIN1 on the BS2 controls the LED. Just connect the LED to PIN1 and make sure you have a 470 Ohm resistor in series with the LED to prevent it from getting too much current.
The Code for the BS2 is written in a form of BASIC called PBASIC. It is very easy to learn and understand. I am not going into detail about how the code works. I recommend going to www.parallax.com and download the manual for free.
The BS2 is programmed through a RS232 Serial port that connects to you PC. Once the EEPROM is programmed, it automatically executes if it has power. You can download the code I wrote for free. I have several different flavors of the Code (see below).
| CW Code |
Use this code for the above circuit shown. Will control any rig with a standard CW key. |
| Tone CW Code |
Use this code if you want to modulate a CW tone through the mic (works great for 2m FM rigs). This will not work with the above circuit. You must connect the output from PIN2 into a "Rig Blaster" or similiar interface. I will have a schematic shortly for this interface. The BS2 is capable of gererating tones at any frequency (as well as DTMF tones). |
