[OZAPRS] HF frequency drift reports ...?

[Terry Neumann]

It doesn't take a lot to confuse me these days.  OK I'll admit it.  I am 
confused by the list of stations Mike has copied below.

I've checked  for myself and that's more or less what the site is 
delivering in real time at this moment.

My station is one of those listed with today's date.   It hasn't been on 
HF APRS since I returned from our Flinders Ranges trip over a couple of 
weeks ago:

http://aprs.fi/?call=vk5atn-15&mt=m&z=11&timerange=86400 
<http://aprs.fi/?call=vk5atn-15&mt=m&z=11&timerange=86400>  gives the 
true picture.   It's in the shed with the HF rig off and the 20 metre 
whip on the bar.  (I just checked)

So why is it appearing in the lists for today?   And all of those going 
back over the past day or so?

Simple answers only please - type slowly .......
