CW Academy

All the way back in 1992 I was interested in Morse code, I purchased a Morse code tape cassette and listened to back and forth to work in my Geo Metro. I never really did pick it up, I suppose because I didn’t have anything to practice with or some driving factor like a radio to train for. I even put it on my evaluation support form as a personal goal in 2003. But now finally, in 2017, I am making (slow) contacts with Morse/CW. I took a class with CW Academy, and it was a very good instructor led, distance learning program.

If you have also wanted to learn Morse, but have difficulty self-learning the skill, sign up for one of their classes.

SKYKING, SKYKING, DO NOT ANSWER.

I previously stumbled on 11.175, but I have become aware of other related frequencies.

11.175 or 8.992 USB (Upper Side Band), Apparently transmitting from Offutt Air Force Base.  Websites that mention this make an assumption that the messages are one time pad, thus are unbreakable codes assuming that the pad is only used once – https://en.wikipedia.org/wiki/One-time_pad.

Other frequencies I have seen listed are:

6.739, 4.724, 13.200, 15.016 – all USB

Technology does some amazing things, but its incredible delicate.  You really can’t stop simple radio signals so maintaining this line of communication is a great idea.  I imagine there was some resistance to keeping and maintaining it after modern Internet Protocol (IP) packet networks matured.  Whatever it is used for, they want to ensure it survives modern communication network failures, which is likely in a high intensity conflict (cyberwar, space asset destruction, etc).

The messages themselves aren’t understandable without the key, but its interesting to listen to nonetheless.

I haven’t monitored these frequencies often in the last few months, but many claim that traffic increases when serious events occur around the globe, which makes these frequencies a sort of indicator of world tension.

Trans-Oceanic by Zenith

I just recalled that as a teenager, I was given a Trans Oceanic 7000 by someone, likely my Grandfather who I recently learned was a amateur radio operator.  I remember listening to radio dramas in the 80s late at night when I couldn’t sleep.  It took a bit of searching to find the make and model of the radio as I just remembered the map that came with the set, but it appears they are for sale from time to time on Ebay and sites like that.  I wish I remember what happened to that set, it was well made and would be a nice addition to my shack.

CHU – Shortwave Time for Canada 7.850MHz

This is the first time I have seen this sort of format – a station transmitting in a four segment transmission.  A carrier, a voice segment slightly higher, a tone segment slightly higher than that, then a data segment beyond that.

They transmit the time in English and French, with a tick beep for seconds, and every minute they send a digital encoded time.

I will have to see if there is a decoder for this or other time stations to synchronize clocks as a project.

This station was fairly easy to find information on, https://en.wikipedia.org/wiki/CHU_%28radio_station%29

Numbers Station on 11.175 USB

I have heard of these stations, but had never heard one on the air.  It is in Single Side Band (SSB).  The first voice was female, repeating sequences of letters in the NATO alphabet.  Another voice came on, this one male, beginning at 7PM US EST time.  This second station likely was not collocated with the original because the signal was much weaker.  Some websites identify this as a Strategic Command frequency, which makes it even more interesting.  I will have to continue to monitor this one regularly.

Interesting to finally catch one of these stations on the air.

Research on the CW Transmission

This was a fascinating find. Apparently this was a maritime station that was idle for many years and then brought back to life by hobbyists. It appears they use the original equipment.

A little more in depth about the previous log – this was captured using Fldigi – software that can demodulate digital communication modes as well as decode CW (Morse Code). I was able to hear this CW transmission and decode it with Fldigi.

The CQ part is the station requesting to speak with any station. DE means ‘from’, followed by the call sign KPH. QSX is a request to listen on a frequency. The transmitting station then is saying – ‘Any station, this is KPH, please listen for me’.
I am unable to understand the rest, I assume the frequencies that the QSX is meant for.

Very interesting find and it is really great that hobbyists are able to keep this piece of history alive.

12.806 MHz is not an amateur allocation so this conversation is something other than US amateur traffic.
