The problem with Rich Text, and the reason why mailing lists refuse it, is
for people who get mailing lists through digests. Digests, where you get
mail a day, and not 50, are useful if you join the APRS list on TAPR. 

So the universal language of the web is universal except for those that
via digests...

Oh dear - it doesn't like HTML.   Neither do I frankly, but I'm prepared 
to recognise the universal lanuage of the internet.

So here is is again in plain old ordinary boring text (sigh).

G'day all,

I'd better respond to this one :-)

1)  Firstly, my station (VK5ATN), like the owner is a bit erratic in its 
appearance.   I usually switch over to  HF packet  at about 1030 hours 
local.  The station usually stays there until about 1600 hrs when I 
either turn off, or go to VHF packet.   It's usually there most days; 
there have been exceptions - when I am not around the place, or as 
happened a cuppla days ago, I had a WinCrash 98 event which occupied my 
spare moments for most of the day.  (It's back after reloading 
Windcra$h, but with a very loud protest from the on-board speaker when 
the windows screen first appears). 

My station is an older MFJ-1278 driving a TS-50 and the antenna is a 
dedicated mono band  inverted V at about 40 feet at the apex.  The 
station has no other function other than as listening and beacon device 
(very selfish). 

2) I've been sharing the same puzzling questions about 10 MHz 
propagation.   In my spasmodic observation of about 4 weeks, the most 
consistent station is VK3MY.  It's there at all times and usually with a 
huge signal.  Unfortunately, it doesn't seem to respond to ping 
requests, at least not in my experience, so I need to keep an eye on the 
S meter.  

VK3WRM/ECV has been there most of the time for the past two days Ron as 
VK3WRM.  I did see you the one day as VK3ECV a week or so ago but there 
was a long period in between when nothing was seen.

Warren's mobile  is there some days - nearly always about mid-day or an 
hour either side.  We are coressponding about this  from time to time.   
No sign of you either today or yesterday Warren ......

The VK4 stations are there most days with VK4DMI getting the most of the 

I have a S3 or 4 background noise level most of the time on 30 metres.   
I need to see what it's all about - I've a feeling the culprit is the 
computer I use for packet and APRS.  

It seems apparent that the biggest challenge is getting a good signal on 
air, and then having a good noise free receiving setup to make the most 
of it.  I speculate whether a V on my larger tower - 60 feet is 
available - and it's further from the computer, would be worth the 
trouble.   I doubt that I'll get the time or energy to do it - other 
projects demand priority - like getting HF going on the tractor for this 
years seeding operations.

My honest appraisal of the situation at present is that despite the 
comparative ease with which I could get a tracker station on 30 metres 
once the HF tinyTrak module is out, I'm hard pressed to convince myself 
it's worth the trouble. I'll probably give it a try because I perceive 
that I'm somewhat unique in having the option of three gateway stations 
at a generous sample of distances from my area of operations. The 
experiment needs to be done.  However, I'm not optimistic, given what 
I've seen so far.   I speculate whether other bands might be better.   I 
wonder whether compressed beacons stand a better chance of surviving the 
hazards of HF propagation and noise.    

I'll continue to watch and put out a beacon every 30 minutes or so, 
however for various reasons you may not see much of me over the next 
three days or so.   Other things will get in the way.  Hopefully gliding 
will be one of them :-)
