Not long ago I purchased an Apex Radio 303WA-2 from Japan. I also purchased this with it: https://www.apexradio.co.jp/it5050_j.html It does seem to clean up a lot of the noise you are seeing - or at the least reduce it significantly enough to be be…

in Interference & a Galvanic isolator Comment by smg March 15

If - say for example, your router / firewall that fronts the proxy traffic is say a mikrotik, you should be able to create dynamic address lists, which get updated when detecting certain types of traffic, then dropping it at the edge using a relevan…

dang - not a lot of SSTV in this part of the world. (NZ)

Another question, is it a genuine Apple charger? ;-)

https://forum.kiwisdr.com/index.php?p=/discussion/comment/20454#Comment_20454 My filter arrived today, and I must say it is better than the Noolec MW filter. I put it before the LNA, as this works the best. The MW stations are still there, unlike t…

in New product accessories in our store: SDR protection circuit, MW filter Comment by smg March 6

I'd like to chime in here and say I have a similar issue, however I have put it down to my network. (even though I build networks for a living) and because I am too lazy to cable my house. The topology looks like: [Garage] -- [KSDR] -- [Switch] -- […

in network problems Comment by smg March 5

I think it all depends on the provider and local laws. As an ISP we are somewhat obliged to take it reasonably seriously if someone comes to us with abusive claims. I get them frequently. However, NZ is limited in its scope with respect to our invol…

in Hackers be hacking.. Comment by smg March 5

The IP 107.191.49.208 is from a data centre in the US, which would lead me to believe it's a VPN based source. The ASN belongs to Vultr.com (formally "The Constant Company") You could email abuse@vultr.com with your evidence as well as hav…

in Hackers be hacking.. Comment by smg March 3

I have one of the Noolec MW filters, and I might get one of these to try. I've posted this before, however there does seem to be two schools of thought. I'm using the MW filter in line with an LNA. I have to use the MW filter before amplification,…

is nginx not an option, as it offers load balancing?

in Status of proxy service instability [should be good now] Comment by smg February 26

I like the fact you don't skimp on quality components, and won't use "compatible" ones based on cost. I used to sell electronic components in Auckland in the 80's, and it was a tough job convincing people to use quality Japanese components…

Nice list of fixes - thank you!

You could probably get away with a speaker de-thump circuit too.

in Quiet switch mode power supply (SMPS) for KiwiSDR Comment by smg January 26

Although this is clearly abuse of the ham bands, it is nonetheless fascinating, especially from someone here in NZ, who is quite insulated to the going ons in that part of the world, where the only real information we get is from main stream media, …

in Anyone know what this guy is saying? Comment by smg January 23

interesting! I had some more this morning. One side was a faint version of what I heard earlier, and the audible side was a robotic voice - possibly masked to prevent from being identified. I have to link to the file as its too large to upload (sh…

https://forum.kiwisdr.com/index.php?p=/discussion/comment/20293#Comment_20293 Thanks, Martin. I have a Noolec LaNA (LNA) and a PGA-103+ (AliExpress) and both appear similar in their characteristic and performance. If however, I put the notch filter…

in Attenuators before or after the pre-amp? Comment by smg January 20

Based on some tests = attenuators before the LNA is better - otherwise I end up with lots of AM broadcast up in the 80m band!!

in Kiwi SDR version 1 behind CGNAT ISP Comment by smg January 12

You might be better off adding the rule manually on your router.

in NAT rule on router forgotten Comment by smg January 11

wow - thats an impressive radio set up. and wow - those Farfadets are impressive too. I suspect they make one heck of a lot of RF scatter across the entire spectrum with a lot of energy.

in Spot the lightning ;-) Comment by smg January 8

FYI - the weather has turned to rubbish here. Raining, cool and thundery. The big green line across the band was the lightning with lots of static discharge from many smaller strikes around the area. We tend to get a lot of sheet lighting here and …

https://forum.kiwisdr.com/index.php?p=/discussion/comment/20188#Comment_20188 OK cheers Martin! I might grab the Ali express one too as its quite cheap. I liked the idea of the Noolec one as it covered the HF bands and was very flat across the rang…
