Delayed Audio - Italian Trucker Channel 45 - 27.465 MHz 27465 AM

[Brian]

A couple of weeks ago I was scanning the 26/27 Mhz bands and came across a lot of chatter on one channel. Don't recall the exact frequency. I think it was probably CB from Europe, maybe Italian. The audio was difficult to hear as it sounded like several people talking at the same time.
I realised that I was hearing the same person talking but also on a delay of about 3 seconds. Everything he said was repeated but slightly weaker and quieter about 3 seconds behind.
I know that some OPs use reverb sometimes but this definitely a delay  of several seconds.
Anybody have any idea of what would cause this?

Lots of high power AM Italian guys use echo and reverb (sometimes to an extreme).  They're often found on "canale 45" or 27.465 MHz / 27465 kHz AM mode.  I know they use other frequencies as well, but 27.465 seems to be their favorite, sort of like 27.025 MHz is to the USA and 26.705 MHz / 26.715 MHz / 26.725 MHz are to the Latin American world. 

During band openings in years past I've heard tons of echo/reverb-laden signals from Italy on 27.465 AM.
