You need a PC with a real LPT port (parallel port) to properly use a DX Doubler as a computer-controlled SO2R box.</div><div class="gmail_extra"><br></div><div class="gmail_extra">However, many SO2R contesters <i>are </i>successfully using Win-Test with two PCs and two keyboards, networked, but Single-Op, with a unique station ID on each PC. This requires a foolproof hardware lockout system that prevents both radios from transmitting at the same time, no matter how they being keyed (internal keyer, internal CW memory, internal voice keyer, external keyer, tune button, etc.). With help from N6KR of Elecraft, I designed a simple lockout circuit for the Elecraft K3 using the TX Inhibit lines: <a href="http://bit.ly/K3lockout" target="_blank">http://bit.ly/K3lockout</a> . While it prevents both radios from transmitting at the same time, there is no priority system. If both radios try to transmit at the same time, neither one will be able to transmit at all. The original design had a priority switch, but the K3 does not stop transmitting fast enough when TX Inhibit is asserted, so this priority scheme had to be abandoned.</div><div class="gmail_extra"><br></div><div class="gmail_extra">I do not know how to do the same circuit for Icom radios, but maybe you can come up with something similar. I leave that up to you. All I will say is that <b>if you are using two PCs with Win-Test, you will be subject to disqualification or similar if your two radios are ever detected to be transmitting at the same time</b>, which is easy to do if you press F1 on both keyboards. Win-Test does not have a software lockout system. Even if it did, it could not prevent you from keying both radios at the same time via other means, such as the internal keyer.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Consider also that two networked PCs don't work so well for serial number contests such as WPX CW because there is no serial number reservation system, so it's very easy for Win-Test to send one serial number in the exchange, but then log another when you press Enter to log the QSO.<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">In sum, if you want to do SO2R with Win-Test, one computer is easier than two, especially if it has an LPT port that can take full advantage the capabilities of your DX Doubler.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Finally, remember that you should really master SO1R contesting before ever attempting SO2R contesting. It's much easier to build an SO2R station than to successfully operate one. Much practice is required.</div><div class="gmail_extra"><br clear="all"><div>73,<div>Bob, N6TV</div></div>
