Hi Stu, > >If you did make a database one thing I'd really like is the ability to run two or more systems and break down which works better on a band. > I've started a new thread on this subject. http://forum.kiwisdr.com/discussion/1817/…

Hi Stu, Yes that worked for me. Good as a workaround but not so good for quick comparisons. However I can now see the OV indicator flashing again, which is what I suspected was happening, so it's not antenna generated IMD after all:-) Regards,…

Same for me, if I refresh the admin page it's back to the original default value :-( Regards, Martin - G8JNJ

Update - my missing spots have now appeared on wsprnet. I think part of the problem may be the response time of wsprnet as it's taking progressively longer to get any response back from the website. I noticed this a while ago but now it's getting t…

Hi John, Thanks for adding that, most useful. Regards, Martin - G8JNJ

Hi Rob, I tried that command but I'm not sure what I should be seeing. I got the response /tmp/wspr-captures: No Such File or Directory and then lines and lines of blocks. I'm not a software guy, so I don't know the command string to increase th…

Hi Rob, It's done it again, the noise plots are uploading but not the WSPR spots. I've tried rebooting but no luck. Which logs should I inspect ? Regards, Martin - G8JNJ

Hi Jim, > >Wasn't extension locking added recently > Yes it was, but the dev extension is not listed among the rest on the extension admin page, so you can't lock it out from general users. Regards, Martin - G8JNJ

You have placed the filter in the correct position. If the attenuation is too high on the MW band you could try adding a resistor between the center pins of the filter input and output connectors in order to by-pass a small amount of signal around …

Hi John, My fault, I expected the dev parameters to only be available via the extension admin page (where it is not visible) and not from the GUI extension dropdown list, where users can fiddle with it. Is there any way I can remove the dev extens…

Hi Rob, I had wondered if it could be some sort of overflow problem as the reboot seems to have fixed it, at least in the short term. I'll keep my eye on it. Regards, Martin - G8JNJ

Hi, I've now been successfully running wsprdaemon on a Raspi for about a month. However on inspecting my wsprnet stats I noticed that nothing had been reported for a couple of weeks, even though the noise graphs were updating OK on the various web…

Hi John, I'm having problems trying to track down some occasional IMD on one of my KiWi's. I think it's ADC overload but with the averaged OV indication it's very difficult to tell. At one time you could set the averaging mask using the developm…
-
Hi John, Ah OK, so that explains what's happened. A couple of my users have complained that when listening to HF airband traffic the background noise is fatiguing and I had suggested they try altering the AGC threshold, but I hadn't realised that …

Hi Ron, Would that remain set upon reboot or after updates ? Regards, Martin - G8JNJ

Hi David, Ah OK, I lived in Llantwit Major for several years and worked just outside Cowbridge (the big mast). My current broadband speed is <10Meg down and <0.9Meg up (which is the critical bit for putting a KiWi on line) and I've been able…

Hi All, This is particularly problematic when the RJ45 sockets incorporate an internal transformer / Balun network with "Bob Smith" termination, as they are not optimised for frequencies <30MMHz and the "Bob Smith" terminatio…

Hi David, OK all good, you are lucky with the Cisco Switch. A lot of the cheaper ones are really problematic. Considering the number of devices you are running including the CCTV, your'e doing very well. I hope you will be able to put yours publi…
-
I'd like to think it would one day be possible, but several of us are already having difficulty in just detecting Galactic noise at frequencies above 10MHz, so I think we still have a long way to go before we would stand a chance of hearing any FRB'…
-
Hi David, I'm pleased you managed to sort out your problem. However I'm a bit concerned about your general arrangement. Mini-Whip antennas, DC switching convertors and PoE have all individually caused problems for KiWI owners due to unwanted noi…

Hi Peter. The FT-817/857/897 series have very poorly calibrated S-meters. The first few S-points are less than 1 dB per division apart. https://g8jnj.webs.com/SMETER.pdf Regards, Martin - G8JNJ

Hi David, Something strange is going on. I would expect the Mini whip to draw perhaps 50 to 120mA of current from a 12v supply, but it's difficult to be sure without seeing a circuit. I know it sounds obvious but is the Bias Tee (the power inject…

Hi Rob, I'm using the late alpha version of WD2.6 found in github: https://github.com/rrobinett/wsprdaemon/tree/rrobinett-v26 Regards, Martin - G8JNJ

Hi All, This afternoon I got wsprdaemon running on a Raspi. It was all working OK and produced noise graphs in the in the /var/www/html folder Edit - the graph in the tmp/wsprdaemon/ folder is being updated. On running wsprdaemon.sh -s and I occ…

Hi John, I've tried the new filters, although I'm not sure if I like the end result, but that may be just me. To my eyes the waterfall looks very 'blurry' with even the mildest settings and weak signals seem to get lost among the 'smearing'. SDR …

Hi Glenn & Clint, Yes I think my understanding of the offsets is the same as yours, so we are on the same page. I think I'll just continue to fiddle them to match the spectrum analyser and not worry about the antenna gain values too much. Reg…
-
It also probably won't deal very well with non-impulsive noise, such as that produced by Switching supplies, Power over Ethernet, VDSL Data over power line, etc. Regards, Martin - G8JNJ

Hi Glenn, All understood. I'm using my TC2M broadband vertical monopole which has a modeled set of gain values that closely match those that I've been able to measure. I'm currently trying to calibrate the wspraemon against values measured with a…

Hi All, In a previous post I said "So should my config be:- DEFAULT:-10,2200:63,630:42,160:22,80:13,60:8.1,40:4.7,30:2.9,20:3.3,17:2.2,15:-1.5,12:-1.3,10:-0.4 Or am I misunderstanding the process ?" I think I was misunderstanding it. …

Hi Ulli, Where are you looking to see any changes you make ? noise_graphs.png in /var/www/html/ Regards, Martin - G8JNJ
