Hi,

Anyone using the HL-2 with cw skimmer server?

I would be interested to know if this combination is possible.

I didn't have any luck, but I was adding a layer of complexity by trying to use Linux/Wine.

I have learnt a lot more about the HL2 since this. I think the likely problem was that the skim server wasn't sending regular packets to the HL2 and the watchdog timer was kicking in on the HL2 and stopping sending packets. It would be moderately easy to modify the HL2 skimmer dll to cope with this, but I don't have any MS Windows compilers I'm afraid.

I'm still working in the background on a completely new skimming method with artificial neural networks to "decode" cw that uses GPU/CUDA. I have a proof of concept working with my HL2, but it is too clunky for anything near general use at the moment. After Steve posted a new gateware for lots of receivers this sparked my enthusiasm again for my project and I did a bit more work on this over the past few months, but progress it slow.

Hi Angel and Matthew,

There have been users in the past who have used cw skimmer successfully with a HL2. I have never tried it.

The neural network cw skimmer sounds very interesting.

Hi Matthew & Steve

Thanks for the comments. I have run SDRC with the skimmer on one band. It is the server skimmer [various bands monitoring] that I am interested in.

I will do some digging to see what I can find in terms of dll.

The neural networks sounds like an interesting project.

Hi Angel,

I don't know if you have discovered this.

I have not tried it yet. I'm waiting on my HL2 shipment from makerfabs.

Let us know if you are successful.

Thanks Mike.
It would be good to hear from anyone who has got it working with a HL2.
