I don't know how horus work but are we sure it can run on a PC w/o GPU?

• Horus on low end laptop problems. - 3 Updates

Horus on low end laptop problems.

Steve <st...@randomaerospace.com>: Feb 15 09:23PM I've been trying to get Horus working on an old DELL windows 10 laptop - I've tried both  horus.exe and webhorus on chrome - both only partly work - maybe 25% of packets are decoded correctly.   Its a bit under-powered (2.4GHz P8600) 4GB ram, SSD - but for horus.exe RAM is only showing 60% utilized and CPU is showing about 20%   Ive tried various soundcard settings, wifi on/off, checked the receivers on other PCs & macs (all OK).   I'm thinking that its just not powerful enough - but the CPU & RAM utilization are not really suggesting a problem.   Any clues/suggestions/things to try folks?       Steve       -- This email has been checked for viruses by AVG antivirus software. www.avg.com

Mika Köching <mika.k...@gmail.com>: Feb 15 01:28PM -0800 Decoding Horus also works on raspberry Pis so I think it should work on that hardware. I would just try with Linux (Debian).   Steve schrieb am Sonntag, 15. Februar 2026 um 22:23:26 UTC+1:

Mark Jessop <lennieth...@gmail.com>: Feb 16 08:20AM +1030 I guess it's possible you could be getting sample drops somehow, but with that CPU utilisation I wouldn't really expect it. I'm guessing you're running v0.6.1 of Horus-GUI, as I think 0.6.0 didn't support CPUs that old. We had to revert to an older version of Numpy to enable it to work on CPUs without AVX extensions (older than ~2009).   That you are decoding OK on other machines is a good sign - it suggests that at least the transmitter is behaving correctly.   Unfortunately at this point it gets pretty difficult to debug what's going on. To check out whether there's some weird audio bug, you could perhaps try recording a sample on that laptop and playing that back (through something like VBCable) on one of your other working machines?   73 Mark VK5QI       On Mon, Feb 16, 2026 at 7:58 AM Mika Köching <mika.k...@gmail.com> wrote:

It doesn't require a GPU.
