Default Optical Communications? RSCB Irrelevance? (Was : The smallest Baird Televisor?)

Been done. UK record, as of a couple of years back at least, was something
like 75km. There is project in the latest RSGB handbook (if you are
interesed I'll look up the page, I noticed the article but haven't read the
detail).



The current UK laser record is around 73km I believe... held by G0MFR
and G8LSD. They used standard low power red laser diodes of the kind
found in the pointers. Barry,G8AGN, Gordon G0EWN and myself (all in
Sheffield) are also experimenting on these lines have done a 45km path
so far... using cw. We have some LOS paths up here in the North up to
136km so we're hoping to better the record one day soon :-)

What you do in the privacy of your own home is up to you!

Powered as it is by AAA cells, it seems to have
a greater power, and a greater reserve of power


Again, what you do in the privacy of your own home.....

Well I certainly didn't waste it doing Google searches, like you do.
Has your copy of the crap film ' Bridges at Toko Ri' bit the dust?


You are quite free to waste your time in any way that you wish; even
on the Internet if you feel so inclined. After all, you say you like
things kept simple. There's no need to feel apologetic.

The shortest Google search would have turned up the information needed
to avoid him making such an obvious statement. A CR2032 battery has a
capacity of 220 mAh at a current drain of 0.2 m/A.A modern AAA battery
far exceeds that - I've left it as an exercise for the OP to search
for that info..


Well we seem to be making progress. You are now acknowledging that you
use Google to gather information and are not trying to pass it off as
your own work. Well done, keep it up!


Unfortunately, you are making no progress whatsoever.

I merely mentioned some characteristics of a typical watch cell,
suggesting that if the OP looked on Google he could have found it out
for himself, thus avoiding posting what he did and looking like a
fool. Is that simple enough for you?

If we could now get you to understand what ' I can't think of anything
else' means, then that would be real progress.


I know you like things kept simple, so I strongly suggest you never
attempt to repair anything at all - you just don't have the brains for
it.

No throwing away of a fine receiver here due to 'nerves', fettling, or
missing pages from the manual. ROFLMAO. In fact, it directly follows
the Gospel According to Gareth, in his (still unqualified and
therefore dangerous) 'repair with gusto' creed; something he has
admitted failing in the past. ROFLMAO.

Is that simple enough for you?

Fortunately I am not confined to my house through fear and cowardice
when the children are not at school, unlike yourself, so I have little
time to waste on anything. Unnecessary embellishment of anything is a
complete waste of time and effort. It's a pity you are too stupid to
know this.


Do your neighbours know you have an excessive interest in the school
holidays?

What is it about the above sentence that confuses you?


What is it about "No throwing away of a fine receiver here due to

(still unqualified and therefore dangerous) 'repair with gusto' creed;

difficulty with? Isn't the statement simple enough for you?

My only interest in the holidays are a deep concern for your welfare.
I know that you, being paedophobic, suffer greatly.


Nice try at blame-shifting, but your excessive interest in the timing
of school holidays is entirely down to you, and is a matter of public
record. Perhaps you'd like to ponder the implications of that.

Don't use me as a cover.

Post the article if your man enough.


If you aren't careful someone will tell your Care in the Community
Social Worker how naughty you've been. You won't like that, she won't
wipe the egg from your face.

The blame shifting is entirely yours. It was your original article
that mentioned problems during school holidays. Perhaps you'd like to
ponder on that!


That was very poor...is the medication wearing off?

Don't use me as a cover.

Still not man enough to post the article eh?


Still not technical enough to repost one of your own articles?

You're getting more childish by the hour. No wonder the kids hate you.

Whatever are you blabbering on about? Truth? Would you know the
