Re: S-METER READING

There you make a mistake. The S-meter only gives the sum of signals at the input, there is no way it will tell the real strength unless your noise floor is 0 volt and this is never the case. I have seen many cases where the s-meter read 9+20db and the other station was barely audible, the reading wa...

Re: S-METER READING

The only thing you measure is the voltage at the input-plug of the receiver. It doesn't say anything about the signal, antenna-system, cable losses, conditions in the sky, etc. Also, on HF it's 50μV for S9 but on VHF 5μV, so on VHF you should see a different reading. But it's just that, a μV number ...

Re: Cheap but usable wire?

Hi Trevor, You can use cheap steel-wire with a zinc coating of about 2mm thick. A roll of 100m will cost about 20 euro/pound and insulators can be found for horse-electrical-fences. Most simple and effective antenna is a single wire of about 50m long en some counter like a fence. Just Google for &qu...

Re: S-METER READING

We Ham Radio Amateurs call the S-meter a Fun-meter or Lie-detector, just depends if the reading is good or bad for you. Don't think anything of it, it's just a reading that you can use to compare signals for yourself and nothing else. Any reading you get has no meaning and also can't be compared to ...

Re: RSP1A and SMA connector

I had it too on 1 box, the SMA connector came loose. I opened the box as soon as I noticed and mounted the connector properly. Do not wait until the coax at the inside has been damaged. I doubt SDRplay will let you lose warranty if you report and repair it yourself. But ask before you do, always best.

Re: Galvanic Antenna Isolators

But the Telenet website uses a longwire without counter, so it's normal to use extra grounding. However with antenna's that hold their own counter like a dipole you do not need grounding, just a common-mode-choke is enough. Like with a battery, if you don't connect both poles there will be no light ...

Re: a rtl_tcp compatible IQ server for the RSP

Added new features, when using -s and/or -f to fix the samplerate and/or freq, the server will ignore any changes from the client.
This is important for websdr.org when using an upconverter, you now simply set the freq and don't use progfreq.

Re: What’s going on here ?? Receiving but no antenna

Hi Stefan, If you overload the ADC it will start giving ghost signals. There are a few options you may want to try: 1: Turn on broadcast etc notches, as regardless the band you are, strong signals mix into other bands if the level is too high. 2: Reduce the gain of the SDRplay a lot, typical 50% or ...

Re: Linux API 3.01 driver stops streaming when the sample rate is changed at around 2.685Ms/s

There is no issue as it's not meant for end-users and also not stated as to be used by non-developers.

I develop myself and removed it, as it doesn't work for my project.

Re: SoapySDRPlay3 driver for SDRplay API 3.01

Why are you using it?
It was stated for developers only and it's not working with most software.

In other topics you have problems, but yet you use the testing-API that is not said to be compatible.

I tested it myself as well and removed it, as it simply isn't useful.
