Re: Mounting Kerberos SDR high up in a tree

That's great! Enabling flexible fixed operation enables the SDR's at much higher heights and crowdsourcing of access like you see with HF SDR sites that are publicly available...

Re: Feedback on possible KerberosSDR V2 Hardware

Some comments on the wish list: 1) Definitely RF switches to enable calibration without disconnecting antennas. This would pave the way for fixed site rooftop installations, and potentially a crowdsourced RDF network. Think about these mounted on towers or rooftops, and taskable from a frequency POV...

Re: A crossed Yagi for 255 mHz. SatCom

Hi... So I am a ham with multiple antennas, mostly in trees because of local zoning issues. I have a 115 ft tall redwood tree, and I was thinking about mounting the kerberos SDR and a set of antennas up near the top of the tree. I have conduit from my house to the base of that tree which has other a...

Re: RTL-SDR's in an outdoor box

Thanks for the reply. Yes, I was planning on putting a powered hub up there, and then using USB over CAT5 extenders to go from the outdoor housing into the attic where the NUC will sit. That way I don't have to try and carry power for the sticks over the USB cable itself, just signal. I'm trying to ...

RTL-SDR's in an outdoor box

Hi. I'm building a new house, and I have the opportunity to mount a few antennas on a horizontal mast on the roof (supported by a very nice heavy duty mast coming through the roof. I am a ham, so I will have a 2m/70cm vertical, a GMRS antenna, a 1090 MHz ADS-B antenna, and a couple discones and mayb...
