Ok Marcus , Needs must , I dont think the frequency translation would be a problem, but any modification to the envelope parameters will degrade performance , the low s/n sdr decodes , point to the l
Hi Graham, following your advice I've now taken out the SpecLab filter / noise blanker again. Not sure whether this will be for the better... anyway I'm aiming for a fair comparison of our two Opera
Marcus , Is the feed to Opera still being pre-processed via SL ? G.. From: Markus Vester Sent: Friday, June 28, 2013 9:50 AM To: [email protected] ; [email protected] Subject
At 90 watts , RN7T , decoding into UK at the moment , improved east-west over the last week ? On the s/n front , Op or wspr is giving a path quality indication , which takes into account ,rx conditio
Hi Markus and Mike, Thank-you for the reports and the favourable comments on my photons. I hope to try some antenna comparisons soon. Thanks for reminding me that the dB values are S/N, Mike. Perhaps
Hi Joe, during this week, your signal has been detected here every single night, along with Mike and Spiros. I have been running the "deep search" correlation detector in parallel with the original O
Joe, I have received your Op32 for the last several nights as follows: 22/23 June: 0259 and 0352 UTC at -30dB S/N 23/24 June: 0141 -38; 0319 -35 24/25 June: 0059 -40; 0132 -39 25/26 June: 0231 -40 26
Dear Group, Will be QRV tonight and grateful for any report. 73 Joe This electronic communication is governed by the terms and conditions at http://www.mun.ca/cc/policies/electronic_communications_di
Well Markus , Those of us with radio controlled clock's salute you ! [And with dfc39-1 just down the road , it must be a hostile radio environment ...] To extract the s/n / dB levels from Op , gettin
yes. I'm aware that Opera should nominally be fed with straight full-band SSB. But going by the first results, the preprocessing seemed to help a lot in the presence of our strong DCF splatters, so I
Thank-you to G3XDV and GW0EZY for the reports of last night's transmissions. The aerial was iced and the current was only about 200 mA. Yesterday, 3 trees had an unhappy encounter with an axe and an
Got exactly two TA detections last night, one from Bob and one from Joe: 2014-02-23 06:04:25 VO1NA 4585km 137555.000Hz 1mHz -47.6dBOp 100% 17.0dB 2014-02-23 05:19:08 WE2XEB 6448km 137546.999Hz 2mHz -
Thank-you Markus for the report and the OPDS grabber. The aerial and its current are both higher; this should result in more decodes. 73 Joe Got exactly two TA detections last night, one from Bob and
Thank-you Markus, Gary and Mike for the reports. The opera will run again tonight, but we are expecting freezing drizzle which seems to lengthen or othwise increase the capacitance of the wire and de
