I have sent a separate reply directly to Gene, suggesting he visit some forum Fri, 16 May 2008 13:05:58 GMT Gene Floyd http://groups.yahoo.com/group/PicoDopp/message/733 http://groups.yahoo.com/group/PicoDopp/message/733 A couple of years ago, I bought a Picodopp kit and tried to find a user's group to ask advice on. Since there was none, I asked Bob for permission to start one Wed, 26 Mar 2008 03:53:35 GMT Jerry Flanders http://groups.yahoo.com/group/PicoDopp/message/732 http://groups.yahoo.com/group/PicoDopp/message/732 What I did requires no circuit changes of any kind to any board - all I needed was two additional antenna termination boards for the two new TDOA dipoles and Wed, 26 Mar 2008 02:13:52 GMT R. Simmons http://groups.yahoo.com/group/PicoDopp/message/731 http://groups.yahoo.com/group/PicoDopp/message/731 That photo tells it all... quite a shot... Don't feel too bad about it, I've heard similar stories from people who carry their $3000 titanium-frame touring Wed, 26 Mar 2008 01:56:19 GMT R. Simmons http://groups.yahoo.com/group/PicoDopp/message/730 http://groups.yahoo.com/group/PicoDopp/message/730 Thanks Jerry, that's a new one, haven't heard of that before... Probably an easier way to drive the PicoDopp into TDOA mode would be to simply "wire-OR" the Wed, 26 Mar 2008 00:00:28 GMT Jerry Flanders http://groups.yahoo.com/group/PicoDopp/message/729 http://groups.yahoo.com/group/PicoDopp/message/729 In reading how the TDOA units work a few weeks ago, I realized that the PicoDopp should function to generate the switching signal. PicoDopp normally switches Tue, 25 Mar 2008 23:06:48 GMT Mike Saculla http://groups.yahoo.com/group/PicoDopp/message/728 http://groups.yahoo.com/group/PicoDopp/message/728 My kind of DFers! Tnx WBob!

They calibrated their beam patterns against a known signal (repeater) and actually measured the two bearings precisely XdB Tue, 25 Mar 2008 20:44:26 GMT Mike Saculla http://groups.yahoo.com/group/PicoDopp/message/726 http://groups.yahoo.com/group/PicoDopp/message/726 Getting better than 1-degree of precision is very difficult. I built an interferometer for 2-meters using two 13-element yagis spaced 1/2- wavelength apart and Tue, 25 Mar 2008 20:14:12 GMT wolfbob http://groups.yahoo.com/group/PicoDopp/message/725 http://groups.yahoo.com/group/PicoDopp/message/725 Bob, and others. As you may remember we had a lot of rules for mobile hunting. As it gets more and more competitive, you get more and more rules until the hunt Tue, 25 Mar 2008 18:47:20 GMT R. Simmons http://groups.yahoo.com/group/PicoDopp/message/724 http://groups.yahoo.com/group/PicoDopp/message/724 It is kinda funny no-one has gathered up all these suggestions and comments into a cohesive list... By rights, I suppose I should do that, and add a page to Tue, 25 Mar 2008 15:55:00 GMT Jerry Flanders http://groups.yahoo.com/group/PicoDopp/message/723 http://groups.yahoo.com/group/PicoDopp/message/723 Thanks Mike, Bob L., Bob S., and WolfBob. Next time maybe we can condense some of your good advice into a plan that will appeal to all our hunters. I will Tue, 25 Mar 2008 03:30:32 GMT Mike Saculla http://groups.yahoo.com/group/PicoDopp/message/722 http://groups.yahoo.com/group/PicoDopp/message/722 WBob points out some good practice here. Beginners are slow at learning Df techniques. For them the transmitter "on" time should be long with brief "off" times Mon, 24 Mar 2008 21:14:52 GMT Bob Ledford http://groups.yahoo.com/group/PicoDopp/message/721 http://groups.yahoo.com/group/PicoDopp/message/721 Congratulations Second place is good but the darn view never changes much.
