Cumulus MX 3022 on Fine Offsett WH-3080 via USB on R7000 AP

Topics about the Beta trials up to Build 3043, the last build by Cumulus's founder Steve Loft. It was by this time way out of Beta but Steve wanted to keep it that way until he made a decision on his and Cumulus's future.

Cumulus MX 3022 on Fine Offsett WH-3080 via USB on R7000 AP

Post by xayide »

So I have now been running Cumulus MX for a while. So far there have been no real issues with MX as far as I can tell. Although I want to give a few heads up for those using Fine Offset.....

First off I ran this via my Server and VMware ESXi using Usb pass through. This made the console reboot quite often and also generated huge unrealistic spikes on solar radiation. So I went a head to investigate further...What I found out after testing is that Fine Offset stations are _VERY_ picky when it comes to supply voltage. I ran my station of a stable server with a PSU of server grade. This didn't seem to be good enough, actually the server did stuff like fluctuating a few milliVolts and also some smaller hiccups probably due to vmware pass through.

So I moved the station onto my DD-wrt router Netgear R7000 and installed this USB over IP software. http://www.virtualhere.com This worked so good I bought a license and moved my Z-wave AND my RFxcom-devices over too. I have now been running this for a week and it has yet to do any rebooting or spiking. Next week I will probably order a USB power amplifier and also a Usb power meter so I can investigate a bit further regarding the voltage issue on this station. But so far I can say bot Cumulus MX and the station seems to like the "virtual USB software"

One reflection is that Cumulus MX is calculating theoretical max a bit lower for Solar radiation than the Cumulus 1.9.4. Since I am now getting my stations values a bit over the theoretical maximum. Maybe up to 10-20% over. What could be the cause? (I haven't touched the default values for solar radiation calculation)

I am utmost thankful for getting the opportunity to be part of this BETA-test!

This has already been noted. MX uses different astronomical libraries - it has to. They presumably use slightly different formulae.
