My regular reports which appear in IRCA's DXWW column frequently mention pip
patterns of various stations.
The 630 situation is that the Romanian and another station, either Portugal or
Tunisia, are out of alignment in terms of the final pip occurring exactly at
top-of-hour. This leads to an apparent 11 or 12 pip sequence when neither of
the close-to-even-strength stations run more than 6.
Roy has heard this on his beach DXpeditions and I also have noted it here at
the house. In both cases SuperLoop antennas positioned for a cardioid null
west clean out most of the 630 domestic activity, largely WPRO.
774 is another frequency with mis-timed pips. Spain with 5 short 1 long
(a.k.a. 5+1) is on the money but Egypt can be 30 or more seconds late.
Most stations use 1 kHz as the pips tone. Portugal's are somewhat lower.
Algeria, Egypt, and some other countries in the Arab world have the final pip
at a higher pitch than the preceding ones.
It wouldn't take too long to have a list put together seeing that webstreams
and remote SDRs could fill in details that might take a little longer to get
via actual DXing. You can also scroll though postings on RealDX and hear audio
clips of a "zillion" receptions from all over the planet. Many of these
contain pips and many have been successfully ID'ed, often by the Finns who seem
to pick up everything.
Besides what I regularly post, the PEI DXpedition reports edited by Bruce Conti
contain a lot of detail about what we hear on the East Coast. I guess there
was also an autumn 2018 Newfoundland DXpedition but I haven't seen a whole lot
of usefully-consolidated / detailed info from that yet.

In the age of remote SDRs etc., perhaps this is
irrelevant, but has anyone made a list of what
pips are used by different
Europeans? Sometimes, pips are all that make it
through, and like knowing the frequency offset,
can hint at what tools (parallel webstream etc.)
might be useful when the signal is a little better next time.
best wishes,
Nick
