Going back to v6.13 didn't improve anything, but it did seem to get
rid of the occasional variations in voltage (from 13.5v down to
12.8v) that SNMP was reporting to "The Dude" software. So, after
letting v6.13 run for couple hours with no improvement, I
reinstalled v6.15.<br>
<br>
Presto! Instant dBm improvement back to my normally observed
values. Here are links to SNMP graphs of the drop @9:30am, and the
rise at 17:48pm. Of course, you can also see this in Nigel's Cacti
reporting, albeit with less horizontal (time) resolution.<br>

<br>
Note that the reported sudden dBm "rise" to -60dBm (the upper limit
I've imposed to keep the graph scale reasonable) on two occasions in
the second graph, is when I upgraded and then reconfigured the radio
(from a cut-&-paste script), and should be ignored.<br>
<br>
Note that a very similar scenario occurred several months ago, when
I upgraded from v6.10 to v6.12.<br>
<br>
Of course, today is Friday the 13th. Maybe Jason is responsible.<br>

morning (well after the update to v6.15 last night) just
after 9:30am, I saw a 8dB drop in both TX and RX signal
levels, which persist at this time. I did a "reset
configuration", which did not solve the problem.<br>

Did anyone do a change at Paine sector 2 around 9:30am?<br>

It's been raining gently all morning. Last night it rained a bit
harder, and I saw no significant or unusual variation. I'm going
back to v6.13 to see if that changes anything.<br>
<br>
The drop was very sudden. I have that antenna connection very
well sealed, I thought, and the Ethernet cable runs uphill to get
into the eaves. I did a cursory visual check of that this
morning.<br>
