An operator sent two screenshots: 76 LIVE in the counter, and the panel beside
it reading "Waiting for spots… Spots will appear as the cluster sends them."
Both his band and mode were locked to the rig — 20 m, SSB — so the filters were
doing exactly their job and the empty state was describing a different problem
entirely. He went looking for a connection fault.
It now says how many arrived, names every filter currently narrowing the list,
and offers one button to clear them all. The band and mode locks are named
first: they follow the rig rather than a click, so they are the two nobody
remembers switching on.
Also times the connection. He reports the first launch taking a while to
produce spots and a restart connecting instantly, which is the signature of a
slow name resolution rather than a slow node — the OS caches the answer, so the
second run skips it. The log now carries the dial duration and the delay to the
first spot, which separates that from a node that simply had nothing to say.
Hypothesis, not conclusion: the next log settles it.
Reported by an operator whose node sends little: nothing for two minutes, then a
reconnect — losing the login, the filters, and any spot that arrived during the
gap.
The read had a 120 s deadline and ANY error ended the session, a timeout
included. That reads a silence as a verdict on the link. It is not: a cluster on
a dead band legitimately says nothing for minutes.
Only a real error ends a session now. A genuinely dead peer is still caught, and
by the mechanism meant for it — TCP keepalive probes an idle connection and its
failure surfaces as an error on Read, not as a timeout. The dialer sets it
explicitly rather than inheriting a default, since it is now what the design
depends on.
One trap the advice this came from did not mention: ReadString returns the bytes
it HAD read along with the timeout. Discarding them would lose the first half of
any spot line straddling a deadline, so the partial is carried over.
Tested: a listener that goes silent past the deadline and then sends a spot —
the spot arrives on the ORIGINAL connection, and the listener never accepts a
second one. The tick is a var so that test runs in four seconds instead of
sixty; a slow test is a test that gets skipped.
Reported on 3 cm. cat.BandFromHz stopped at 23 cm, so a 10 GHz frequency came
back EMPTY — and an empty band is not cosmetic: the QSO is logged without one,
counts in no award slot, and exports with no BAND field. The low end was short
too (2190m / 630m / 560m).
Four band tables had to be extended because four exist: the CAT one, the award
plan in app.go, the cluster spot classifier, and the frontend's. Plus the places
that LIST bands — the QSO editor and award-definition pickers (you could not set
3 cm by hand either), the statistics axis, and the award band ORDER, where a
missing band sorts to the end instead of in frequency order.
Ranges and names are ADIF 3.1.7, which is what an export has to carry.
A test now pins one frequency per band across the Go tables and asserts they
agree — that is what was missing, four hand-maintained copies with nothing
checking them. It also pins that an out-of-band frequency stays empty rather
than snapping to the nearest band, which would file a QSO under a band the
operator never used.
