<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi Kurt, <div><br></div><div>The Firmware version for Mercury should be reporting 6.0 if you have loaded the firmware in the download package for PowerSDR v1.19.3.1.diversity2. Mercury v6.0 firmware will run the PowerSDR v1.19.3.1 version and KD5TFDs version too. </div><div><br></div><div>However, the Tx OC PTT problem you (and I, now) observe doesn't seem to be associated with that at all. The character of the problem pulses that appear on the Penelope J6 PIN 13 OC PTT line seem to be dependent upon the sample rate that is selected (192000, 96000, or 48000 on the PowerSDR>Setup>Audio panel). At 48000 Hz sample rate the pulses do appear much like a clock, hihi, but at 192000 Hz sample rate the spurious pulses are much fewer in number and much narrower in width, at least on my system. Looks like maybe a timing problem in the USB comm link to me.</div><div><br></div><div>I do not see any such pulses on the PTT line when I run the W5WC PowerSDR v1.19.3.1 program and activate the PTT line so the issue is certainly due to my diversity Rx mod code additions somehow (maybe indirectly, actually). Perhaps the extra processing time is creating some kind of timing problem and some tweaking of the buffer sizes may need to be done. The xmit audio sounds fine here even when the PTT line pulses are present. </div><div><br></div><div>I'll stay on it until I figure it out and get it working properly. </div><div><br></div><div>Thanks again for the feedback!</div><div><br></div><div>73, Joe K5SO</div><div><br></div><div><br><div><div>On Sep 23, 2010, at 1:23 PM, kt wrote:</div><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: medium; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div bgcolor="#ffffff"><div> </div><div><font size="2" face="Arial">Going back to diversity2 K5SO 17SEPT2010 , always the same hardwaresetup , the pa relay remains inactive.</font></div><div><font size="2" face="Arial">The Firmware Versions in "PowerSDR Setup HPSDR" used for this program are: Ozy 6.0 , Mercury 3.0 , Penelope 1.2 , K5SO- 09/08/2010.</font></div><div><font size="2" face="Arial"></font> </div></div></span></blockquote></div><br></div></body></html>
