K4KPN-15 APRS Digi/I-gate Outage

November 15, 2018

Update 11pm local: 

  • K4KPN-15 has been back on the air since around noon local time.
  • The Dry Ridge site lost its primary internet feed due to an extended power outage impacting an upstream distribution facility. The site was quickly failed over to a backup connection via the inter-site Canopy WAN. Another good test of “Plan B” procedures and resources. Also a reminder of the dangers of using the internet as your backbone minus a lot of redundancy.  What is your Plan B and C?
  • Also a good lesson that just because you have generator power doesn’t mean other adjacent 3rd party systems will have the same. Don’t be lazy, plan accordingly.

K4KPN-15 is temporarily down due to widespread ice storm related power outages in the region. As previously noted that site has no backup power nor is it considered a priority site for power/service restoration.

The Dry Ridge site (K4KPN-10) remains online even though it has transferred to generator power twice in the last few hours due to the controller not liking the input power quality. Guessing the grid feed there is just barely holding on. Well at least we have our first real world storm induced test of the recently repaired transfer switch 😉

The Jonesville East site (K4KPN-1,-4,-6,-13,-14) has alarmed a few times due to power fluctuations, but all gear there remains fully functional with the UPS systems handling those brief brownouts/drop-outs. Security cameras show significant icing on the antennas and trees there, but I have seen worse.

Obviously expect the usual signal degradation from iced up antennas. Remember that depending upon the design and band involved, ice accumulation tends to degrade antenna efficiency and drop the resonant frequency to varying degrees.

Talking with my Dad and friends there the predicted “trace” of ice turned out to be considerably more than just a trace. A client said the sounds of limbs cracking and transformers exploding started around 1am and intensified into the early morning hours. Judging by the reports and outage maps the Cincinnati area is dealing with the impact of a serious ice storm.

Judging by radar the freezing rain is almost out of the area. Once that stops and the temp stays above freezing things have a chance of melting off. Telemetry shows 32.2F at K4KPN-4 and hopefully that will start climbing soon.

Welcome to Winter 2018-2019. While snow and power outages are commonplace here, it is odd hearing about 4-land nuisance snows and a nasty ice storm during the Fall months. Makes one wonder what else Mother Nature has in store for us when Winter officially arrives.
