EU_Sprint, the DL2NBU softwareThe DL2NBU software is very similar to the K1EA software, CT, but is specifically designed for the EU Sprint contests. It outputs the file in the correct log format, so we prefer you to use this software. The screen layout and most of the commands are similar to CT, so if you are used to this software, it is very easy to adjust to.
The software will run on any MS-DOS computer, version 3.3 or higher. It will also run on Windows 95 and 98, and should run on Windows 2000 and Windows XP, although you may need to 'play' with it to get it to work on 2000 and XP.

ASC2RESThis little utility converts the EU Sprint .ASC file outputted by the DL2NBU software to a CT .RES file, to make importing the QSOs into a general logger easier. The author is Sil, I2YSB (tnx)
CW Keying Interface Circuit Diagram (from K1EA's CT9 User's Manual, page 17/18)Morse code is sent by keying the DTR line of any of the four serial communications port, or the STATUS line of a parallel printer port, LPT1 or LPT2. The circuit needed to key positive-keyed radios from COM1 or COM2 is a 1K resistor from DTR (pin 20 on a DB25, pin 4 on a DB9) to the base of an NPN small signal transistor (for example, a 2N4401 a 2N3904, etc). The emitter of the transistor and the ground lead of the transmitter keying cable are connected to signal ground (pin 7 on a DB25, pin 5 on a DB9). The collector of the transistor is connected to the transmitter keying cable (hot, not ground side).
The circuit needed to key positive-keyed radios from LPT1 or LPT2 is a 1K resistor from SLCT (pin 17 on a DB25) to the base of an NPN small signal transistor (for example, a 2N44401, a 2N3904, etc.). The emitter of the transistor is connected to Strobe (pin 1 on a DB25). The ground lead of the transmitter keying cable is connected to signal ground (pin 18 on a DB25). The collector of the transistor is connected to the transmitter keying cable (hot, not ground side).
