Any Hermes Lite 2 users on here? #sdr #hamradio #hermes #amateurradio

@G6PHF I'm borrowing one this weekend

@w8emv had mine a couple of weeks now. Very impressive
@G6PHF What software are you using to drive the Hermes Lite 2? It looks like I have a few choices. Could be Linux (Pi 4 or Pi 5) or Mac, no Windows in the shack.
@w8emv well. I’m normally Mac or Linux only. But I made an exception for this and bought a sff windows 11 pc to run Thetis. I do loath windows but I’m putting up with it for this.
@G6PHF @w8emv I’m using a small Asus ultra sff sized PCs with Proxmox virtual machine software. It’s easy to spin up a windows VM or a Linux VM for different configs in a minute or two… and delete them if no they are no longer needed. I’ve got Win 10 VMs for skimming (CW skimmer Server is Windows only); Windows VM for Thetis; one for SparkSDR etc. I find it handy to keep working configs in a pristine environment and setup a new VM if there are major upgrades to be done
@g7vkq @w8emv makes sense. I have a proxmox server in the garage for Linux stuff. I couldn’t be bothered (didn’t have time) to play about with the audio devices and usb pass through etc. Also my shack is in the house and I believe you’d need HDMI console to get decent performance for something like Thetis. It runs nicely on an i7 along with wires x, log4om etc.
@G6PHF @w8emv 👍. The servers are really physically small. They have Ryzen 5700U processors with 6 cores/12 threads, 64Gb of RAM & 1Tb of SSD; plenty big enough for the jobs I have for them. HDMI console is easy on the desktop (assign GPU to VM, along with a USB port for mouse/keyboard). I have a separate Ryzen 5600X box on the desk for Thetis (avoids audio / USB pass thru😀). I segregate the network traffic on VLAN…the Red Pitayas/HL2s live elsewhere in the house (spare bedroom & outside).
@g7vkq nice setup. What are you using the red pitayas for? That’s not something I’m familiar with - intrigued though 😀
@G6PHF I’ve a few of them - the cheaper ones can run an 8 band OpenHPSDR compatible trx & the more expensive one has FPGA space to run two separate 8 band HPSDR trx. You can even run standalone WSPR/FT8 receivers. I feed them to skimmer software or Thetis in the same way as the HL2. You need more hardware for a proper trx …but for skimming a basic RP works perfectly(although an antialiasing filter is useful for 10m FM broadcast images). This is what makes the magic https://pavel-demin.github.io/red-pitaya-notes/

Notes on the Red Pitaya Open Source Instrument

@G6PHF the Charly 25 is a full blown trx based on a RP…with add on hardware to make a pretty comprehensive physical receiver. However many RBN nodes just use a RP as a receiver without any extra hardware. https://charly25-sdr.github.io https://www.reversebeacon.net/pages/Red+Pitaya%2C+preparing+42
