345.6 Warble

This morning I heard a faint but distinct two tone warble on 345.6, which I believe is the secondary UHF emergency frequency. Any idea who or what would have been originating this signal?

I know this is one of those channel names type of frequencies but I can't remember the name for it. You know, three, four, five, six. But I've never heard of a secondary ELT type of emergency frequency. I'd be interested in knowing if there was one myself.

I've had this in my list forever as a secondary emergency frequency but who knows where I found it. It did sound like an ELT but only lasted for 10-20 seconds.

I have it as UNIFORM 2.

345.6 is USAF 'STRAIGHT'. It was a common tac call frequency.

Hearing a warble on same frequency in Oklahoma City. My guess is it’s a signal coming from an E-6B Mercury aircraft.

Isn't the UHF emergency 243.0 MHz?

Isn't the UHF emergency 243.0 MHz?

243 is guard like 121.5 but for military

I heard an ELT twice on 243.0. Once at the Cleveland airshow when a medical helo bounced on landing, and another time from who knows where.
