Hello,
We have 4 clients connected to Baldi-S1 (a SISO sector) that are kind of
silly:
# INTERFACE RADIO-NAME MAC-ADDRESS AP SIGNAL... TX-RATE
UPTIME
0 wlan1 AF7PR-Baldi E4:8D:8C:C6:F5:45 no -60dBm 32.5...
2d8h51m46s
1 wlan1 KD7TQN-Baldi D4:CA:6D:C2:ED:93 no -65dBm 32.5...
2d8h51m32s
2 wlan1 N7OEP/Baldi-B... D4:CA:6D:0D:53:F9 no -60dBm 32.5...
2d8h51m27s
3 wlan1 Rattlesnake-B... 64:D1:54:AF:3F:CD no -79dBm 19.5...
1d9h35m21s
They're silly because the first 3 are at the same mountain top, just a
couple hundred feet away in adjacent shacks. This is a waste of prime
long-range spectrum, being used to do local-links. I'd like to get all
the shacks @ Baldi tied together via gigabit Ethernet, and install
access switches at the 2 other shacks so people there can plug into the
LAN directly. This high speed LAN between all shacks can then be used
to allow us to address the 4th silly client, which is Rattlesnake
Mountain. I'd like to install a dedicated dish on the northernmost
tower (fed by the new high speed LAN) to act as a dedicated high speed
link between Baldi and Rattlesnake. The dish on the Rattlesnake side
will also need a modem upgrade to run at full speed, and I'm including
that in this proposal.
Here is the rough budget for this spend request:

Procedural reminder since we haven't had one of these emails in way too
long: HamWAN directors have 24 hours to vote upon such spend decisions,
and members have the same time to weigh in with opinions to influence
director votes. Our procedures are documented here:

Same for heavy RF nearby. If cat5 cable is already there it's worth
testing, but even if it tests well issues may occur over time, or you may
find Ethernet ports fried after a lightning storm.
Also be careful of ground loops when interconnecting buildings - one
broadcast tech told me of a big tower NE of Winnipeg where the ground cable
between equipment buildings was so hot it would melt snow due to the ground
taking a path that it shouldn't have.
The last paragraph is a great point. For setups I often run dual fiber
lines and only use one of them, so that there is a spare. If something cuts
your conduit and all the fiber lines, you have a bigger problem.
I know that I'm late, just following list digests, but I always recommend
putting fiber in lightning / RF prone conditions such as this. There are
quite cost- effective options If you know where to look, if anyone wants I
can price out some out.

My connection (K7DCJ-Buck) has been down for a few minutes a couple of dozen times in the last two days. Is the source of this known, or is it at my place?
