I usually write about as many drafts of an article as I build prototypes of a circuit I'm going to publish--that Wed, 04 Nov 2009 04:04:38 GMT ajparent1 http://groups.yahoo.com/group/r2pro/message/661 http://groups.yahoo.com/group/r2pro/message/661 Hi, I have the published article and it's not mentioned there. I also found that feature maddening as a transceiver. The mod I used was to parallel R5 with a Tue, 03 Nov 2009 17:03:59 GMT rjbrjb20022002 http://groups.yahoo.com/group/r2pro/message/660 http://groups.yahoo.com/group/r2pro/message/660 Thanks gentlemen, for your helpful responses. I think you've nailed it, too much juice coming down that antenna. Now that i think about it, that antenna was Tue, 03 Nov 2009 05:34:35 GMT KK7B http://groups.yahoo.com/group/r2pro/message/659 http://groups.yahoo.com/group/r2pro/message/659 Hi Bob and Kevin, That warm up behavior is an unintentional "feature" of the microR2. I think the original article described the long warmup time as similar Mon, 02 Nov 2009 23:37:20 GMT w7loz http://groups.yahoo.com/group/r2pro/message/658 http://groups.yahoo.com/group/r2pro/message/658 My microR2 also delays its turn-on in a similar manner, though I don't get the interference you mention during that delay. I believe the delay is due to the Mon, 02 Nov 2009 18:32:37 GMT rjbrjb20022002 http://groups.yahoo.com/group/r2pro/message/657 http://groups.yahoo.com/group/r2pro/message/657 Greetings to the group, i am new to this list and hope to get some tips and info regarding KK7B's innovative designs. I just completed building the Kanga Sat, 24 Oct 2009 00:43:10 GMT ajparent1 http://groups.yahoo.com/group/r2pro/message/656 http://groups.yahoo.com/group/r2pro/message/656 ... If your doing CW only there are many choices of circuits. For SSB I'd say use the uT2 as it's good and has many things you need for good SSB plus CW as Fri, 23 Oct 2009 03:55:39 GMT Ron Thompson http://groups.yahoo.com/group/r2pro/message/655 http://groups.yahoo.com/group/r2pro/message/655 Thanks again, that pretty much covers the basics, it would be a matter of choosing the transmitter exciter then. I have an idea for analog noise blanking that Fri, 23 Oct 2009 03:15:44 GMT ajparent1 http://groups.yahoo.com/group/r2pro/message/654 http://groups.yahoo.com/group/r2pro/message/654 ... No noise blanking or noise reduction. The only way I know is to drop the analog part of the R2pro and use DSP(computer) to synthesize the function and Fri, 23 Oct 2009 01:44:06 GMT Ron Thompson http://groups.yahoo.com/group/r2pro/message/653 http://groups.yahoo.com/group/r2pro/message/653 ... One of the drawbacks to the DC design that I haven't found much information on is noise filtering and blanking. I'd sure appreciate some insight on how Thu, 22 Oct 2009 15:31:51 GMT ajparent1 http://groups.yahoo.com/group/r2pro/message/652 http://groups.yahoo.com/group/r2pro/message/652 Hi, Design, Yes I do that some but I enjoy just experimenting using back of the envelope scratch designs. build test, modify, test and repeat till Thu, 22 Oct 2009 00:23:24 GMT Ron Thompson http://groups.yahoo.com/group/r2pro/message/651 http://groups.yahoo.com/group/r2pro/message/651 Thanks Gary, this is definitely on the list of features to look into. Maybe in a couple of months I'll have a progress report to post to the list.

I've got until Field Day to have something runiing and tested. I'm interested in what you've done. A drawback for me is Wed, 21 Oct 2009 19:16:39 GMT Gary http://groups.yahoo.com/group/r2pro/message/649 http://groups.yahoo.com/group/r2pro/message/649 Complete info on Rick's binaural receiver is in the March 1999 QST article available at: http://www.kangaus.com/Documentation%20files/BIQR/biqr.pdf It's like a Wed, 21 Oct 2009 15:25:04 GMT w1kilofoxtrot http://groups.yahoo.com/group/r2pro/message/648 http://groups.yahoo.com/group/r2pro/message/648 Ron, I've been (slowly) working on what I call the T2Pro. It's an implementation of the 'advanced' design in EMRFD. I've put the Express PCB schematic and
