Disabling all repeaters today stopped bad CMR
Posted by john in Precision Ag, Trimble on September 9, 2009
We were spraying today within 5km of the base station and having the bad CMR DATA problem. Since the repeaters were not required I switched them to another channel – disabling them. The problem went away. I’ll need to reactivate the repeaters tomorrow
Turning TURBO back on
Posted by john in Precision Ag, Trimble on September 8, 2009
Due to CMR losses at Repeater 1 I’m turning TURBO back on
SNB 900 at Repeater1 failed
Posted by john in Precision Ag, Trimble on September 1, 2009
The SNB900 radio at repeater 1 died and has been replaced SN 4831A26728 The new radio has older hardware — the same as at repeater 2
Turbo off – so far so good
Working with Turbo Off, spraying fungicides. No problems with CMR. Working in H5 & H6 close to repeater 2
More BAD CMR
Had another busrt of BAD CMR data packets today while applying UAN in H3. 1km from Repeater2 working with TURBO on, CDB2 off
Bad CMR Data again
The day after turning TURBO MODE on we had a couple of bad CMR packets come through. We’ve had 2 days spraying with TURBO MODE on and on both days we received corrupted CMR data. This is with Controlled Broadcast off. I’m turning TURBO MODE back off & still waiting for the new 12dBi antennas [...]
Configuration Change
Posted by john in Precision Ag, Trimble on July 23, 2009
The RTK network has been working faultlessly with Controlled Broadcast turned off. However CMR % has been in the low 90% range and fallen as low as 25% in the middle of the night at Repeater1. I’ve decided to turn TURBO Mode back on. Testing so far seems to indicate that it’s the SNB900 radios [...]
Transfering a running system to a kvm image
Posted by john in Linux, Linux Tips on July 20, 2009
Got an old Linux system that you’d like to transfer to your nice shiny new KVM host. It’s easy to do with dd ssh root@192.168.1.1“dd if=/dev/hda” | dd of=/var/lib/libvirt/images/imagename.img Will copy the machine running at 192.168.1.1 to the image file name imagename.img . Ready for you to setup as a VM. All that remains is for you [...]
