Another ARA-2000 rebuild and LNA approach

It's always rewarding to see that distributing and sharing open knowledge & tools ultimately leads to much more individual empowerment and faster technological evolution/innovation than “protection” of “Intellectual Property” ever could: OK3ZB copied and used the AWRA-Cutting-Helper, did a successful rebuild of the Active-Wideband-Receiving-Antenna and came up with a new LNA approach:

D-Link "green-ethernet" switch Review

Labeling things with the term “green” has become quite popular these days. While evaluating unmanaged SOHO Gigabit-Ethernet switches for Apollo's core net-infrastructure, a lot of “green” switches turned up. After sifting through numerous datasheets D-Link's DGS-1008D seemed to be the top choice when power consumption is an issue.

Review: Managed Low-Power Switch DGS-1100-8

In a past Mission-Log, we've reviewed the power consumption of "green" Ethernet Switches (consumer-grade/unmanaged) that could be used in off-grid environments and they performed really well. Compliant with IEEE 802.3az Energy Efficient Ethernet, these switches consume less energy by cutting down on power consumption when the traffic volume is low and automatically measure the length of the connected cables to adjust power usage, when cables are shorter than 20 meters. In addition, they monitor …
