I’ve noticed LINK-11 (TADIL – Tactical Digital Information Link) transmissions in the 6940-6950 kHz region the last day or two. Operators may wish to avoid 6950 kHz, and perhaps even 6955 kHz, especially while these transmissions are occurring.
I have no idea where these transmitters are located, but if I had to guess based on propagation characteristics, I’d say maybe Canada or out in the Atlantic.
LINK-11 is operated by the US military. I’m pretty sure you don’t want to interfere with it.
The Canadian Air Force has occasionally used 6955 for years as a net frequency. Luckily,their transmissions seem to occur in the early afternoon hours,EST/EDT,and again are rare.
The LINK-11 transmissions have been common in the frequency range mentioned since at least 9/11/01 and seem to have no set schedule I can discern.
I’ve always done what Chris suggested,and avoided them.
IMO, there’s no point in ticking off two government entities,especially one that has the power to send you on a vacation to a cell overlooking lovely Guantanamo Bay w/o due process.
