Re: QO100 beacon signal level

I should have thought, even that is not so simple. You have to know what bandwidth the SNR is being measured in to be able to compare. An interesting point. I've no figure for when I tried, must get it going again. The SNR however you measure it should be set by the time the signal leaves the LNB. D...

Re: QO100 beacon signal level

David,
Signal strength readings mean nothing.
Compare the Signal to Noise Ratio, then decide if anything is wrong.

Re: Flash woes

"I've never had a CPU die on me." Quite a long time ago I had a collection of compatible CPUs and motherboards. One stopped working. I moved the CPU to a working board, it did not work. I put another CPU into the original board, it did not work. I do not know what failed first but I had the situatio...

Re: "Ethical Diamonds"

Yes, a complicated situation. Like how far back do we erase history, if we removed Chinese-made items we'd have very little left.
The designer of the 888 etc is happy to see them produced for us to use.

Re: Current requirement

I've not got a USB3 current meter but thought it was about 800mA.
Your extras could well make the total 1.5 Amps, I've never thought it wise to approach the maximum specified for any PSU.

Re: RX888 working fine...then died!

Yes, I had a similar thing with a 666 but that recovered when cool, I added a fan.
It greatly reduced the drift as well as enabling continuous use.
And, possibly increasing life although these days things usually become obsolete before breaking down.

Re: change screenshot path

I'm another one who likes to have all screenshots, saved pictures etc in the same folder.
As Eelco says, no big deal but I like to think I have some little control over my computer.

My notes "If it's drivers then Device Manager looks like the left picture here https://www.sdr-radio.com/rx-666#Driver if good like the right.

Re: ISS pass prediction differs SDRC-PstRotator

Hummm, Looking at this thread I see a very busy person trying to avoid being even busier by asking for detailed information. Simon is generally extremely helpful. Many times I have seen a request and been surprised by how he jumps in and fulfils it. I'm not sure a coding genius can be expected to be...
