1954- someone with a bit of CW
Thanks for that info DimBulb...interesting.

Someone tuning in a CW signal sending the callsign WF2XMP

That callsign is authorized for several HF frequency bands, 6770-6970 kHz being one of them. 25 kW ERP! I wonder what 24K0J1D emission is. 24K indicates a decently wide signal (24 kHz bandwidth)
Edit: I should have clicked the second link :o
Rockwell Collins, Inc.
Form 442
Rockwell Collins, Inc. (“Rockwell Collins”) seeks to
add four sites to its existing experimental
license, WF2XMP. The four added sites, in
Tampa, Florida, Denton, Texas, Kansas City,
Missouri, and Arlington, Virginia, will be used fo
r over-the-air testing in
support of the US Navy
Office of Navy Research (ONR) contract N00014-12-
C-0363. The scope of this contract is to
research higher data throughput capability over
the High Frequency (HF) spectrum for mitigating
Beyond Line of Sight (BLOS) data transport
risks in satellite denied environments.
The transmit sites at these four
locations will be used in the over-the-air demonstration of 4G
ALE software to analyze HF signal propagati
on and then choose the best frequency of
propagation and the supporting modem data
rate and bandwidth for high speed data
communication.
The 4G ALE software is designed to maximize
the data throughput that can be achieved using
HF communication equipment. The data collected
by the 4G ALE software will be used to
independently verify that the best frequency of
propagation and data rate
s are being selected by
the software.
The over-the-air demonstration is the real time ve
rification of performance that has been tested
using HF channel simulators in the laboratory.

now you have me thinking that maybe the 24 hour operating station called "old time radio" that has been operating for years @ 6.770Mhz may be part of some sort of a "test" they are doing.

That thought crossed my mind as well. Although OTR hasn't been transmitting the digital mode that the 24K0JID emission entails, and OTR hasn't IDed
