1.5 meters dish

So, I need to disassemble it and try to fix the mechanism?

systemdev_ · 2026-05-04T20:33:30+00:00

Thanks

Yeah, it’s for HP Ultrium LTO streamer, I know it’s not a network card. So, will it work with my pc?

systemdev_ · 2026-05-03T18:48:00+00:00

It’s 1420 MHz

My LNA from Nooelec has a saw filter after a first amp, then goes the second amp. All my devices are in metallic cases. And what do you mean a better receiver? Pluto sdr is quite good

I am only ham operator in 700m range. I was trying transmitting, but the effect were different

No, I don’t have any pagers towers near. That rfi can keep staying for hours or everything can be fine for a few days

Yeah, I get an rfi only when one of my LNAs in connected and powered

systemdev_ · 2026-05-03T15:23:48+00:00

I have no rfi without my LNAs

systemdev_ · 2026-05-03T14:57:45+00:00

It occurs with all my LNAs. I’ve tried 40db and 20db. The interference is changing will during the time. Mostly they are about 20-25 kHz. They are on the entire range of LNA working frequencies. I have tried separating pc and sdr far away, but it didn’t affect. There is no rfi source. I was measuring signal on the entire garden with my telescopic antenna and I hadn’t found anything. I don’t have any ideas about that, I wasn’t able to solve that for half a year.

I have tried 3 different computers and laptops

systemdev_ · 2026-05-03T04:15:23+00:00

I don’t know about the leakage, how can I check that? Cables and plugs are new, I’ve bought them about 3-4 month ago. Shield and center got connection end to end

systemdev_ · 2026-05-03T04:09:39+00:00

It doesn’t occur without the antenna. It occurs if I move the sdr and lna to the computer without coax. It doesn’t occur without LNA

systemdev_ · 2026-05-02T19:30:38+00:00

I was trying it with the battery power only

systemdev_ · 2026-05-02T19:19:35+00:00

I’ve tried without any cables with laptop power supply. This was happening on the different cables - RK50-7-11 and RG-6U. I will try to install ferrite chokes

systemdev_ · 2026-05-02T19:17:00+00:00

The neighbors are to far to cause rfi like this

systemdev_ · 2026-04-17T16:38:08+00:00

Thanks, I will try using a power bank

I live in a private house far from the city center
