Subject: ! sinclair MK14 wanted
Hi,
I am trying to locate a Science of cambridge (Later to become sinclair) Mk14
computer. The computer was available in a home built kit in the UK and, from
what i am led to believe, many were sold to amateur radio enthusiast, as, at
this time they were the only people experimenting with electonics in the
home build environment. (Hence my reason for posting in this group)
If you have one, or any spares, or indeed any sinclair items ie radios,
calculators, watches, etc, working or otherwise, that you would like to sell
please email me as i cannot regularly access newsgroups.
I would also possibly be interested in early home computers from the late
1970 to the late 1980s. Preferably boxed but all will be considered.
Thank you in advance.

Subject: ANNOUNCE: APRS Protocol Specification Version 1.0
I'm happy (you don't know *how* happy) to announce that APRS Protocol
Specification Version 1.0 was approved by the APRS Working Group on
August 29, 2000 and has been made available for download at the Working
Group web page, http://www.tapr.org/tapr/html/Faprswg.html.
This Version 1.0 (technically, due to change control, version 1.0.1)
document is nearly 130 pages long and does a tremendous job documenting
the APRS protocol as used on the air in the summer of 2000. We should
all thank the Working Group members, and especially Ian Wade, G3NRW, the
Technical Editor who actually wrote the thing, for their hard work.
Although the process took far longer than anyone anticipated when we
started, I think the end result is definitely worth the wait.
Where do we go from here? Although this is an excellent document, it
almost certainly still contains errors, omissions, and ambiguities. In
addition, it reflects only the current protocol, and not any of the areas
in which the protocol might be extended. The WG members will be meeting
at the DCC in Orlando next month and electronically thereafter to put in
place a mechanism to deal with requested corrections and enhancements.
The WG Charter outlines a way to handle this, but experience has shown that
some modifications may be necessary for a workable process.
Also at the DCC and thereafter, the WG will consider adding new members.
Since its founding, several new authors have come on the scene, and two
of the original members have resigned. Any author of software or firmware
implementing the APRS protocol who wishes to join the WG should contact
me (jra@febo.com or n8ur@tapr.org) directly. Please -- we need to hear
directly from those interested in joining, so rather than writing to ask
that someone be considered, encourage that person to get in touch with me.
Also, please remember that the WG is not affiliated with TAPR. Membership
decisions will be made by the group, and I can't tell you now how many (if
any) new members will be added.
73,
John Ackermann N8UR

Now, can you get Kenwood to follow the damn thing, and fix their
bastard radios?

Subject: Distance?
Thanks very much to everyone who replied, especially to J. Hoffa and Paul
Keinanen for your long and detailed replies. I won't be able to do what I
wanted due to the technical difficulty and cost of such an operation.
As I've mentioned bandwidth down here is really expensive. There is a new
service launching early next month that will be providing 2MB links at an
unbelievably (for us) affordable price. The only problem is that this new
service won't be available in the local town soon. I wanted to hire the
service in the closest city and communicate with my equipment in that city.
Just for interest's sake, how much do 2.4GHz repeaters cost? And also, where
can these usually be put? Do you hire space from somebody else's tower?
Thanks again everyone.

It is becoming more and more clear that you aren't looking for AMATEUR
radio at all. You are in the wrong group.
As amateur radio enthousiasts, we normally are not looking for a cheap
replacement for a leased line, but we are interested in experimenting with
radio. With that motivation and a lot of lobbying, we often get telco
tower space for free.
When you are just after cutting under the telco's own rates, they probably
won't be that considerate.
