Antennas • Dual V-Dipole

Built a V-Dipole antenna for NOAA and Meteor and was getting great NOAA reception but Meteor images would be great but only getting image south of my location. Once the satellite passed overhead the nothing would show up on image...just black. I thought then, why not build a dual v-dipole with 2 east rods connected together and the 2 west rods connect together.

Of course, now all NOAA images are very noisy and Meteor cannot obtain (SDRsharp). Verified solid connections and resolder the antenna rods. Any help would be appreciated!!!

Quadrature display plugin for gqrx?

Quadrature display plugin for gqrx?

I've noticed that someone has made a quadrature viewer for SDR#, and I'm wondering if anyone has ever made a similar plugin for gqrx?

Nice. Why don’t you answer then?

Is buying from Aliexpress any good?

I recently decided to upgrade my attempts at receiving weather sat images by getting an LNA and some filters. However, sites other than Aliexpress (e.g. amazon, ebay) are ludicrously expensive here. In particular, are the items in the links below any good?

User Projects • Re: How to buy an SDR chip

in my opinion, RTL2832 is a bottleneck. It works well for 20 dollars dongle receiver.
But if you want something better it will turns into the weakest part of your device.
It has small dynamic range, it has bad IMD, it has spurs, it has too small bandwidth...
It even cannot utilize all parameters of 820T/820T2 tuner.

I think it's better to use some real RF frontend, for example based on LTC2165 and some small FPGA for DDC.

It will give you professional level of parameters for your SDR ;)
