You are correct Nate. I am not well versed on the terminology. I like the phrase tropo enhancement as that probably explains the repeater here chirping earlier this week as I would believe the Papillon 715 repeater is much closer to Seneca than the distance between the 285 machine to Russell 285 machine. Thanks for explaining, but there is still some brain fog. Technical reading requires me to read multiple times and then hopefully there is some understanding that happens.

Even though I don't think you meant it this way, Mike, I will offer a
clarification of "open" and "closed" repeaters and the use of subaudible
tone, CTCSS on FM repeaters.

These days the rule is that a repeater is "open" or "closed" as a matter
of policy as set by its owner/trustee.  Per our service rules, once an
operator is informed that a repeater is "closed", i.e. limited to
certain stations, that becomes a binding policy of the repeater.  To use
the repeater contrary to that policy is also a Part 97 rules violation.

There is no technical measure that must be implemented to create a
"closed" repeater.  It is a matter of policy only.

Conversely, the use of technical measures to mitigate interference from
users of another repeater is encouraged and by themselves do not make a
repeater "closed".  That said, the use of such measures does have an
impact.  There may still be old FM gear in use that does not have CTCSS
capability.  Then it is up to all involved to decide how best to handle
the situation.

When the 147.285 repeater goes back on the air (I did some trouble
shooting on it last week and will revisit it after harvest) it will
require an 88.5 Hz tone for access.  The reason being that it doesn't
take much tropo enhancement for users of the Russell 147.285 repeater to
also bring up this one.  As the Russell repeater is part of K-Link it
also requires a tone for access.  Per policy our repeater is "open" as
is the 444.350 repeater.

73, Nate
