It's on during ascending passes in the northern hemisphere, which should be your local afternoon passes. It turns on by timer at roughly 30 degrees latitude (this varies a bit) and is on for 7 minutes. THe link on www.ao27.org that says "24hr listing" will give you the exact repeater=on times. Look for "Analogue Med". I think that being as far North as you are you may only have a few minutes per pass visible for you.

Good Luck

AO-27.

Easysat ? ... right !!!l.

I've been trying (unsuccessfully) to figure out how to tell when the AO-27 transmitter is switched on over my QTH ... (Frei Island JP33WB) ... or not.

Of course, any tracking program tells me *WHEN* the satellite is over my QTH but tracking programs don't tell me whether the transmitter is switched on or not.

The AO-27 scheduler supposedly does this ... the only problem is ... I find it thoroughly confusing.

The passes (according to any tracking program with the latest keps) and the AO-27 scheduler don't seem to agree ... (me'thinks John is doing something wrong !!!) ... or ... from the scheduler I can see if the transmitters are on (or not) when the satellite is well out of my footprint ... but I'd like to know whether it's on when the satellite is workable from my QTH.

Is there anyone out there who can explain in words of one syllable (or less) how one figures this out ... and then explain it to a thick and illiterate old sod like me.

This mail is in NO WAY meant as any form of criticism of the AO-27 scheduler, it is ENTIRELY me being TOTALLY stupid! and not being able to see the wood for the trees ... and asking for HELP.

How about an example that a 5 year old could understand? (Even I might have a chance then).

At the present time, the only way is to compare the Analog Medium transponder "on" times from the 24-hour listing (which are UTC, by the way) with the times for visible passes at your QTH. No one program available today will give both.

The Java program that my son wrote for me gives you the ability to see the satellite's current state, as well as the 24-hour listing, without having to have internet access (except to update the data files occasionally). The best part is, you can look ahead at any future date (assuming the satellite's on-board schedule doesn't change), which you CAN'T do from the AO-27 website. It is available to download at http://www.cs.rit.edu/~cjh9783/programs/satsched.php . It's free, but feel free to make a donation to AMSAT if you find it useful. Make sure you update the data files from the File menu the first time you run it.
