E10 schedule research

As mentioned in the E10 section, we received a current schedule for this station constructed by member ‘AlphaVax’

The chart shows schedules for ART, EZI, FTJ, JSR, PCD, ULX, YHF

Now read on for the analysis of AlphaVax & MysticOne:

This is the result of an ongoing schedule research project for finding complete skeds of the regular E10 callsigns. At first big thanks to my Italian project partner MysticOne.

It started originally in December 2002 and had taken 4 weeks to get the schedule partially complete in January 2003. In December 2003 I found MysticOne from Italia on IRC. He has better reception of E10 than me in middle Germany. Until some changes we got a first complete result in January 2004, but there were no plans to make it public anyway.

After continuous monitoring E10 we started again checking the schedules at the end of 2004 and noticed again some slightly changes in them.

After starting a third phase of research in October 2005 we have now finished the third complete, most accurate and up to date schedule.

After rejoining the Enigma 2000 group we decided to publish our results in the Enigma2000 newsletter.

At first I have to say that the schedule from YHF is changing some timeslots frequently approximately 2-3 times per year. Also doing so is EZI.

Whilst the others, namely ART, FTJ, PCD and ULX are changing very seldom some slots (we noticed only 2-3 changes in last 3 years), JSR was not changing any slot in last 3 years of our monitoring period.

So the schedules have to be rechecked every year. But over 98% of the slots are not changing.

As a result the skeds give us an overview what’s really going with E10 every day! You can use the tables for an easy check of what E10 is on air now, assuming the current propagation lets the waves going to your Rx :)

Please note that the irregular stations are not listed because they pop up every now and then and do not have fixed Schedules/frequencies.

This applies to CIO,SYN,VLB,KPA and MIW which appear on a fixed time, but changes their frequency each month. Also the others like FDU and HNC which are seldom and nearly not predictable are not mentioned here.

If someone is listening one callsign permanently for hours and propagation is good, then you will probably notice, that E10 is playing heavy with transmitter power and antenna parameters. We will try to make a list for that thing too.:)

As a last thing i will state that each callsign execept JSR has 42-45 slots per day, and some of them are repeat slots, which are changing some times too. JSR is only 23 times per day on air. Nearly 40% of the slots are often idling, which means a '2' is sent after the callsign instead of messages. JSR is here an exception too, which has maximal 2-3 slots idling.

The messages are changing mostly every 10-20 days, except in the slots which are repeated. These messages can change sometimes daily!

There are also some messages which stay on air over many weeks. So we have a total number of 145 unique messages per day.

All in all nearly 4000 different messages per year are sent. The average of the groups per message is nearly 66 (calculation is based on getting the group count of 500 messages) so approximately 250000 different groups are sent by E10 per year.

Perhaps in another article I will write some stuff about the control stations and special strings sent by E10.

So I hope this is enough as an introduction to our work, now enjoy the skeds and listen to the E10 lady.:))
