Irish Churches 11 meters 1750 UTC
« on: October 20, 2012, 1753 UTC »
Hearing a bunch of them right now, all NFM:
27610
They tend to fade in and out over a period of several minutes. My advice, if you're interested in hearing them, is to view the waterfall with your SDR, if you have one, and select any strong signals that look like FM. Otherwise, just tune around until you find a strong FM signal.

27506
27631
27637
27650
27680
27688
27742

27810

Interesting that a lot of these seem to be on random frequencies.  Ireland's Wireless Public Address System (WPAS) service offers two sets of frequencies and the option of AM or FM modulation.  While the logs on 27.xx0 and 27.xx5 make sense, there's signals on 27.637 and 27.688 and whatnot.

The WPAS system allows operation on 10kHz spaced channels from 27.605 to 27.995 (no gaps, AM or FM allowed) and 27.60125 to 27.99125 (no gaps, AM or FM allowed).  The 27.60125-27.99125 allocation is the same as the UK 40 channel FM CB "27/81" allocation and would explain the signals on 27631, 27650, 27680, 27742, 27810 and 27890 kHz.  Have all of these been FM that you've logged?  Maybe these churches are really just picking a frequency between 26 and 28 MHz and going with it.  The 27506 kHz one isn't even a legal frequency for WPAS or CADS

(and yes I know this is an old thread I just thought I'd share the information about the WPAS (and whatever the UK version is - Community Audio Distribution System / CADS - which appears to only operate in the 27.60125 - 27.99125 allocation with FM mode only, legally speaking anyway).

Yes, I recall they were all FM. I don't think I have heard any since then, there was a big opening on 11m that weekend.
