your MW OV is likely less severe than mine but perhaps not. In any event, I built discrete notches for the offending mW stations and that solved things. You might also consider as a

Rob Here the 1660 station is about 10 km @ 10 Kw daytime 1 Kw night time and the 1560 is about 5 km @ 5 Kw daytime and 1 Kw nighttime. I have another one with 4 phased towers about 2 1/2 km at

In Maui the Flamingo was not enough to suppress overloads from the 10 Km distant 5 KW 550 AM station. A friend designed a custom replacement which suppresses 550AM by more than 60 dB while passing

Greetings, y'all I am now chasing ov events here. Have installed the Flamingo - am bandpass filter, but seemingly still have some ov events around daybreak. The culprit are likely to be traced to two

I have recently become aware of how little many Kiwi users appreciate the importance of filtering the RF feed to a Kiwi so as to minimize RF overload events. Each Kiwi receive job run by WD logs those

No, those are not benign and your log file will grow unbounded. Can you email your conf file and I'll log into it. -- Rob Robinett AI6VN rob@... mobile: +1 650 218 8896

As far as I can determine wsprdaemon is running fine since I got it started a day or two ago. I have noticed that the log file is full of repeated error messages of this type: Mon Oct 18 12:30:01 UTC

In WD 3.0 I will add checks of the receiver names to the config file validation function. Thanks for the reports -- Rob Robinett AI6VN rob@... mobile: +1 650 218 8896

I have 2 public systems, jimlill.com:8075 has a Nooelec filter, jimlill.com:8073 has HB notch filters on the nearby very strong MWBC stations. You can compare...

With any kind of decent antenna and a reasonably quiet site, the Kiwi needs 10+ dB gain to get signals above 10 MHz to be stronger than the internal noise of the Kiwi RF amplifier. Of course that 10

Rolf, Currently I have one antenna for the KX4AZ/T WD site - a random wire dipole that is resonant at about 3.4 MHz, roughly 15 feet above ground level. I am still tweaking the matching/feedline

Bruce, It's amazing how far you can go with almost nothing. I am usually running QRO here at 200 mW -:) into an old Cushcraft R7 usually on 7 and 14 but then again there are some crafty

Some final comments on my "radio limbo" experiment. I've left it running since October 7th and will shut it down today (October 17th), in order to reclaim the step attenuator I've been using to

Gwyn, Thank you for the quick feedback, happy to know the noise data is being uploaded & with the correct location. Doesn't matter to me whether it is -T or /T, either way it helps me distinguish the

Hello Bruce Your noise data are being reported to the database. There's lots of documentation on wsprdaemon.org on how to query the database, but a quick query brings up the following as a few recent

After a bit of a struggle with naming conventions for my remote receiver site 'KX4AZ/T' at EN74gc, I was able to get wsprdaemon going yesterday on the Pi4, so that spots are now being reported from my

Rolf Using "Quiet receiving site", curve C and "galactic noise" curve D from ITU-R P.372.8 as a guideline, one can probably stand a system noise more than 20 dB above KTB before it impacts SNR from a

Rolf, I am using three different amplifiers built by N4CY Everett Sharp. They all are 11 dB gain. He has changed the version several times, one has a relay to disconnect the antenna when no power is
