Happening right now. A female radio operator is sending EAM traffic with RTTY again. Strange. Time 0120z

Guys, here's 2 recordings you may find interesting. One is of the EAM broadcast on 10-10 with what sounds like RTTY synched with the transmission, I originally captured this on 11.175. If you listen to the recording you will notice the signal strength varies. That's because I was clicking through the other GHFS common EAM frequencies to determine if the RTTY was present on all frequencies, Note at the 4.26 minute mark the RTTY signal is not present. The frequency at that moment was 6712. It was the only frequency the RTTY signal was not audible.

The other recording was captured approximately 15 minutes prior to the above. It is (I believe) an E6B transmitting the identical EAM on 6697. A quick note, I have not logged an EAM transmitted on 6697 in over 18 months.

Hey, possibly Token will shed some light on this. Any comments appreciated.

It may be that we are going to use that music for psychological warfare!

Default Voice & RTTY

I believe the voice over RTTY or vice versa depending on your perspective was an operator error.

Assuming this originated off a Rockwell Collins URG-III system site, there are many ways this inadvertent error could happen. The USAF utilizes a highly customized control system for this radio suite. There is extensive cross patching capability at the control points.

Obviously, radio to telephone (either commercial or DSN), packet, RTTY, various encryptors and so forth as well as good old voice can be patched into the audio path of the system. The sites are connected together via SIPERNET (Secret Internet Protocol Router Network (SIPRNet)). This interconnection mode is employed to connect both individual user sites as well as the station(s) in the network.

It is fairly simple for an operator to make such an error. Potentially audio going to another transmitter, i.e. sitcom could have been “bridged” to the URG-III HF voice path. By the way, there is a “bridge” setup command in the operator console software….

It’s a good catch by our “eagle eared” listeners, however, I would suggest one not read too much into this intercept, and I would consider it an operational error unless we hear more of it.

Hi Mike,

BROADLEAF was correct, however, PALMLEY was in fact PALM LEAF.
