Hearing "Johnny" and "Sammy" talking on 27505 kHz AM - 27.505 MHz AM, signed off at 2052 UTC. The way these two stations were talking, it was clear they knew each other and are likely local to each other. 27.505 (or "channel 50") is actually channel 8 on the high band, or band E, but is almost always referred to as channel 50. It is popular with locals in my area too for "private" communications. Even though a lot of the traffic heard above channel 40 is SSB traffic, there are some channels that almost always seem to have AM signals on them. 27.505 is one of those channels.
Continued listening for another couple minutes and didn't hear anything else on this frequency.
