• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

HF Milair multiple radios

"Undulate" is doing multiple radio checks on MARS freq 13927.1 MHz USB
with MARS Operator AFA1EN. Undulate says he is near the US East Coast; AFA1EN is
in Indiana. Both are Lima Charlie here in Florida. Undulate gets checks on his four HF radios

Note the aircraft has four HF radios giving redundancy and the ability to monitor more than one critical frequency at a time.

just curious

Not to answer for n4vo but Al Stern is well known for his HF utility logs and
monitoring reports - I've been using his logs for many years as an excellent and
accurate source of frequency and HF info.
MARS 13927 rotutinely has milair comms active and Al is reporting that he heard Undulate actually do comm checks with AFA1EN on Undulates four HF radios.
Most likely Undulate is a known and established callsign\military aircraft from previous logs and monitoring or stated during the comm checks that he was an aircraft near the east coast - typical position reporting for a comm check.

Actually even if I saw an Al Stern post\log that he heard aliens on frequency _____, I'd be making my aluminum foil hat with one hand while tuning with the other...he's very good.
