I get some TDoA users, but not enough to demand something like this. In the evenings I get many casual shortwave listeners, so losing the two waterfalls isn't so great. I did learn this weekend that my antenna is pretty good for 20 meter WSPR and I'…

Well, I must be doing pretty well! 20 Meter all spot totalled 2100 in 12 hours.
-
Awesome idea. Is that count unique calls or all spots reported?
-
I have a near-corner fed vertical delta loop, 75 ft apex up, base 10 foot from ground, 4:1 currently with some future tests to see if a different ratio may be better. Besides getting a nearby Invisible Fence RFI issue fixed, its done well enough, br…

Basic question. Is the active loop mostly for improved LF performance and limited space situations? I read quite a bit about them but not too much on how they compare to a passive large wire loop. Given enough space, which way would one want to use?
-
An unfortunate thing can happen for us folks living around metropolitan areas where we can get more than few Kiwis running. On the TDoA map, the little name box for one Kiwi can cover up others within the area around it. See Northeastern US for an e…

Playing TDoA golf. WA2ZKD, W1EUJ and K1RA on WCBS gets me about 4 miles away from the transmitter, on the GW Bridge. Edit: Yes - WA2ZKD. The Linchpin on Lake Ontario.

I notice that you're 3/4 channels in use and the remaining one is password access only. Wonder if when you are in that state you drop off the list?
-
@G8JNJ @jks I found that when you see the list filling out partway down, that clicking on the scissors of the top 'empty' slots clears them for entry. FWIW.
-
@jks I went thru the same process to figure the same at about the same time, almost down to the sentence. TDoA ID entered, that works well, it allows to cut down and tailor the marker name to TDoA needs but keep the sdr.hu name what it needs to be -…

Got updated. Not seeing my Kiwi on the map though?
-
WOW! I need to upgrade my GPS antenna ASAP. edit: Installed one of those PCTEL 40 dB timing antennas - consider W1EUJ upgraded and ready for TDoA.
-
For this to work, does the GPS need a good fix, or is the timing information from a few satellites sufficient? I'm wondering if I need to bump up the priority on installing a better antenna on the rooftop.
-
I'll run that by the installer. I really am lucky to get this far with the neighbor and they do depend on it for their dogs/horses safety so I am going cautiously and backed up with whatever the installer says or is OK doing. My last post on the su…

Source found - the neighbor with the barn has an Invisible Fence system (Model ICT-801 transmitter) on the same wall of the barn that my loop is parallel to. I've read that installing a Corcom 10VK6 filter on the transmitter output should knock this…
-
Ordered a high current linear regulator off Alibaba, should be here soon enough. Added #43 toroids to all the things, and even one more at the antenna end. Again, it seems like improvement but not the solution. Getting a friend's loop to help diag…
-
Yep, installed a 1:1 on the antenna coax as well, per same specs and installed at the same instance as the one on the loop. Agree on the approach with the wandering loop - happen to have a long length of RG-58 to work with. A couple other tests com…
-
I'm pretty much letting these people into my 'house' and use my bandwidth - knowing where the user is 'roughly' from and what they are listening to is a fair exchange. That its public? That's another thing, but I consider the value I get also useful…

All the stateside SDRs I can look at right now (limited to Port 80) are chock full of listeners of 9395 - VORW Radio International. The host tweeted out the links for the night's broadcast.

A balun made to target the 3-8 MHz region (per Steve G3TXQ) was made and installed this evening. Also fabricated one for use at the barn end of the cable. Its seems like it made some difference, 80 meters a bit cleaner, but overall not significantly…
-
I have a 4:1 balun on it now, but that could stand an upgrade. All other cables at the Kiwi end have been wrapped through that type ferrite core, pretty much as you described but a few less turns on the Ethernet. I don't get any noise by the shield-…
-
Update: I've replaced the Bullet link with a CAT6 running (pinned to the ground with lawn staples) 200 feet from the house to the barn, all of the old RF link equipment was inactivated. Linear supply replaced with a 3-prong type with EMI filtering o…
-
Thanks for the feedback. I've been running the Bullet POE using a lab power supply - I noticed a lot of issues with the noise with the original POE injector. I'm going to run a long cable out to the barn to eliminate the Bullets and see what chang…
-
I have to think that the quickest experiment is to shut down the house for a moment, bring my IC-706 on a battery and see what 40 meters (the worst affected band) sounds like. If its the same then sucks to be me. If not then I've got some chance to …

The JPGs don't really do it justice.

In AM, it sounds like a higher pitched version of driving over rumble strips.
