Hi Mike ...

Do you see DBF39 on 138.830kHz. This is a carrier, interrupted by
data bursts every few seconds. Monitoring this station will give you a
good indication of whether amateur signals will be visible. If it is
above S5, you may have a chance.

I need to check. I was not watching 138.83 at this time. I think I've logged
DCF39 sometime ago and some other utility stations between 120 and 140Khz -
RTTYs, MSKs, etc , but on a lower frequency, 129KHz I suppose. The Algerian
BC peaks S8 sometimes (100Hz filter) but it's a 2MW station (ERP?).

Anyway, it's summer here and every day we have tropical shower around 18:00
UTC - it lasts for an hour or so - but its effects remains all night long -
static crashes - dropping at 07:00 UTC. May be I need to wait for autumn /
winter, which is the dry period here (40 ... 90 days with no rain at all).

Thanks on the info.
