Listening with an Icom R75, Los Angeles area, picked up a fluttery
signal on 17660 at about 1445Z, woman announcer in slow French
(didn't sound like a native speaker) with music that slowly faded by
1455Z, couldn't get an ID.

EiBi IDs this frequency at this time as "GAB African Music", which
isn't much help. Anyone have any ideas?

This would be the African nation of Gabon, quite possibly in French.
However, Gabon also shows up (as Afrique No. 1) at the same time, in
French, on 17630 kHz. It ruotionely puts in a moderate to strong
signal here in California. Could one of these be what you were
hearing? Does AN1 broadcast on two nearly adjacent freqs at the same
time?

It was definitely on 17660; propagation was very poor but the French
announcing was intelligible until the signal faded. I don't recall
hearing a strong parallel signal on 17630 but I'll check again tomorrow
and see whether I can hear an ID.

Thanks for the response.

Here is some additional Feb 2007 detail from BDXC website, further
supporting DxAce's assertion. It strikes me as odd that the frequency
used would be so close to that used simultaneously by the major
broadcaster in Gabon, possibly even the same wavelength. I assume
that, in the event the opposition station were to be operating on a
very close channel to AN1, this 17660 jammer would probably desist -
or maybe this close juxtaposition never happens.
