The band data output provided on the LPT port cannot be automatically switched to track the active radio. As you noted, it can only be set to Radio 1 or Radio 2 in the LPT port configuration screen.<br><br>Most people find it more reliable to switch antennas by using the band data ports on a radio, if available, rather than band data output provided by a computer port. That way you can still operate when the computer is off, and the correct antennas is selected automatically. This is done via a band decoder box (radio band data port -> band decoder box -> 12V relay antenna switch and bandpass filters).<br>
<br>Another common approach is to acquire a 6-port / 2-radio switch, such as the <a href="http://www.arraysolutions.com/Products/sixpak.htm">Array Solutions SixPak</a> or the <a href="http://www.microham-usa.com/Products/Antenna_Switches/double%20six%20switch.html">microHAM micro Double Six Switch</a>. These boxes accept band data from two radios (via two intervening band decoders). It's an expensive solution, but very reliable, and they allow any radio to operate on any band. No software or computer is required.<br>
<br>The microHAM MK2R/u2R and the YCCC SO2R box have accessory port pins that can be activated based on the current band selected by Win-Test. Type MKSETUP [Enter] and OTRSPSETUP [Enter] in the Win-Test logging window to see the large matrix used to configure these output pins.<br>
<br>Another approach is to dedicate each radio to separate bands, and use two coax switches, one per radio. If only one of your radios has a band data port, connect that radio the automatic switch, and use a manual switch (or one driven by the Win-Test LPT port) on the other.<br>

<div><div style="font-family: tahoma,'new york',times,serif; font-size: 12pt;"><div>Hello,</div><div>Sometimes (quite often, really), I want to use 2 different radios in a given contest, but still operate SO1R. In the normal station configuration, all the antennas are switched by a single switch unit, and I have an A/B switch operated by the SO2R box to route the antenna socket of the appropriate radio to the antenna switch unit. What I would therefore like to do is have WT set the band data on the LPT port according to the active radio. So, for example, I may want to use Radio 1 on the higher bands, but Radio 2 on the lower bands. When I press '*' to switch radios, I would like the antenna switch to change too. Is this possible? So far, I have only managed to work out how to set WT to derive band data from R1 OR R2, but this is a 'once only' setting, down in the
menus.</div><div>Please tell me I am missing something glaringly obvious, or failing that, please tell me there is a neat work-around.</div><div>Obviously, when I make an attempt at a contest using SO2R, I re-jig the station so the A/B switch does not operate and route another, extensive (Not! HI!) antenna system to Radio 2 directly. Then, it all works beautifully, it's just in the 'Let's have a play in this contest for a couple of hours' scenario that I have a problem.</div>
<div>Any ideas would be gratefully received.</div><div><br></div><div>73,</div><div><br></div><div><br></div><div>John,</div><div>G4DRS</div><div></div>
