I also got out my DMM to do some voltage checks on LPU before I power any of the boards back up. I do have a good solid 13.8V DC out of my power supply and all other rigs are working FB. I can say that the Mercury/Ozy combo is also working just fine, but I will double check the voltages to be sure. Hopefully nothing else is harmed other than that cap.<br><br>Looks like it might be time for a digikey order.. :-)<br></div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br>Thanks to all who have replied so far. <br><br>73!<br><br>Vern -- KC8YOH<br><br><div style="font-family: arial,helvetica,sans-serif; font-size: 10pt;"><font face="Tahoma" size="2"><hr size="1"><b><span

Hi Vern,<br><br>ist his the capacitor C4 left of T2?<br>If yes, this is a tantal capacitor. Tantal capacitors are a weak point in<br>circuits and I avoid them as far as possible. I have assembled a ceramic<br>capacitor on my Penelopes for C4.<br>You will have to replace this capacitor and I recommend to no more powering<br>this board. You risk to burn traces on the board.<br><br>73, Gerd<br>DJ8AY<br><br><br>Message: 12<br>Date: Fri, 9 Oct 2009 12:51:09 -0700 (PDT)<br>From: Vern Kollas <<a ymailto="mailto:spoonman1227@yahoo.com" href="mailto:spoonman1227@yahoo.com">spoonman1227@yahoo.com</a>><br>To: <a ymailto="mailto:hpsdr@lists.openhpsdr.org" href="mailto:hpsdr@lists.openhpsdr.org">hpsdr@lists.openhpsdr.org</a><br>Subject: [hpsdr] Penelope -- Letting the smoke out...<br>Message-ID: <<a ymailto="mailto:716445.96693.qm@web54205.mail.re2.yahoo.com"

I decided it was time to get both my Mercury and Penelope updated with<br>the latest firmwares....? Mercury went fine as always.? However, when I<br>powered up Penelope, she started smoking...? :-(<br><br>I have powered her up a few times before without any issues, but since I am<br>still waiting on Alex/Pennywhistle, I haven't had her installed in Pandora.?<br>After a little investigation, C4? (located right up next to T2) is the<br>culprit.? Any ideas what might be shorting out this cap??? If I plug it back<br>in, it just smokes some more.... No other parts seem to be hot or anything<br>like that.? Otherwise, nothing else has changed since I last had it powered<br>on.<br><br>Any ideas of what I should check first??? <br><br>Thanks in advance and
