The con ical I was describing is a Marconi R1900

Not sure what freq ranges are scored but my RX at http://www.wa2zkd.net:8075 is intended to work for the range 1.8-30 MHz. Antenna type and filters severely limit performance below 1.8 and should not be counted. the /status url option gives the sys…

I'm glad that PSU worked for you. Although as switchers go, it seems to be low noise, a linear PSU is still the best method, just more $

Looking at the various informal wspr Challenge sites, it appears that > 1/2 of the top 20 reporters are running kiwiSDR and wsprdaemon. :-)

Some may wince since this is a switcher, but I find they are pretty quiet and an easy way to get going, reserve current and plug and play https://www.amazon.com/5V-4A-Power-Supply-US/dp/B0749668H2/ref=asc_df_B0749668H2/?tag=hyprod-20&linkCode=df…

Relative to that topic, is there any how-to, guide or documentation anywhere to improving and tuning reception quality on your KiwiSDR? I do not think there is anything in one spot. There are many excellent posts here in this forum. Here's a summar…

There are many KiwiSDR owners who use them for wspr spotting. KD2OM is one, who by using wsprdaemon and a 8 and 14 ch. kiwi on 2 different antennas is usually 1 or 2 in N. America or in the top 5 or so worldwide. I have 2 14 ch units are 2 antennas…

If you were to look at some of the top voted RX on sdr.hu, they aren't so great. Overload and spurious on them.
-
rating receivers is pretty tricky... I see few ranking sites that are indicative of actual usefulness of receivers

I agree with Ron

I wasn't sure it would do tabs...
-
It may take multiple instances of your browser and routing with something like jack or pavucontrol. Or at least that is where I would start
-
Ulli says small core are OK... generally so, but here at the RF swamp I live in... I find bigger cores seem to help and are easier to wind besides!
-
It worked very very well and yes, we did win WNY section that year. We ran multi-op class
-
I once made an antenna for covering US and Canada that consisted of multiple terminated sloping 200 ft. wires, The feedpoint box contained relays and xformer and the antenna could be steered one of three directions by controlling the relays with DC …

I have used those Acopian, bought used on eBay. I now use Condor supplies. Both work well.
-
Drooping wires will negate gain... be careful of that
-
I knew about the basics and never touched by WD box. Unfortunately some reset theirs I think. I shut my scraper down during this morning for 8 hours so that it wasn't "nagging" wsprnet. Today's data on it will not be complete. Who knows…
-
WD handles the backlog, Rob can explain
-
Ulli, that is not correct. I run WD 2.7a on 2 14 channel kiwis and my spots are flowing nicely since wsprnet came back.
-
I gave up on all those "eBay grade" new supplies and bought Condor linear units which can often be found used on eBay
-
today shown below, the previous day the signal at 7350 was much stronger (Image)
-
The day I ran the BW test, there was a strong modulated AM station right at the + 5 KHz position
-
what does this display show on the modem/router (Image)
-
point your browser at http://192.168.1.88:8073, I guess you have done that.... but that's what to try before struggling with access from external IP
-
can you access 192.168.1.88:8073 from within your LAN
-
what address are you trying to access locally?
-
I would think something as long as BrixhamKiwiSDR might cause issues at some point

Penn is working now, just needs to do DDNS
