Here's a sound file for a Conamara-style pronunciation of a phrase we often get asked for:

Tá mo chroí istigh ionat.
taw muh KHREE ih-SHCHIH OON-ud
/tɑ: mə xri: ə's´t´i uNəd/

The broad ch /x/ (kh in my phonics) is like ch in loch /lox/ (lokh), never like k. It may help to think of a very breathy h pronounced deep in the throat. Could also be described as the sound people make when clearing phlegm from the throat. But sure, the sound is in the sound file anyway.

Actually, if you pronounce it the way you describe it, you'll probably end up with something like [ħ ~ ʜ]. It's no deeper in the throat than /k/ is xP

While I'm at it, I might as well try to provide an Ulster pronunciation so Lughaidh can later come in and chastise me for my failings.

You are correct that ch /x/ is "as deep" in the throat as Irish c /k/. However, /k/ is deeper in the throat than an ordinary /h/. Therefore ch is deeper in the throat than an ordinary English h (or Irish h) /h/.

The important thing is that the sound is more like a "raspy" h, and not at all like an ordinary k sound, in any native dialect.

Yes, of course.
