Subject: FBB Hierarchical Address Problem?
To: ham-digital@ucsd.edu
A number of stations are reporting difficulties with the latest FBB
version and the hierarchical address. The BBS specification has always
called for 31 characters maximum but the new FBB seems to limit out
around 23. Does anyone know if FBB is limited to less than the
specified maximum?

To: ham-digital@ucsd.edu
I'm interested to know who's going to the TAPR conference in
Tuscon at the begining of next month (March)?
I went last year and had fun and even learn a few things. I'm going
this year so I hope it will be more of the same.

Sandy,
Have you had any luck getting WEFAX on your 1278? I have a new one and
so far, can't seem to get WEFAX to work right. I think the unit may be
defective. On the same receiver, an AEAFAX adapter worked fine. My
faxes are smeary, the 1278 seems to have a problem with the edge
detection.

Subject: TEMPEST - Electronic Eavesdropping
To: ham-digital@ucsd.edu
Transient Electromagnetic Pulse Emanation Standard (TEMPEST) is the
US standard defining the amount of electromagnetic radiation that a
device may emit without compromising the information it is
processing.
In the US it not illegal to posess TEMPEST-surveillance equipment but
it is illegal to take appropriate counter-measures to prevent
surveillance. The US government has refused to release details of its
TEMPEST research and has restricted the dissemination of independent
research by classifying it.
The US Drug Enforcement Agency (DEA) makes use of TEMPEST secured
electronics and computers as they believe that the drug cartels may
possess surveillance equipment.
I am interested in gathering comments on the social, legal, ethical,
and technical aspects of use of TEMPEST surveillance equipment in
the US and Europe with the aim of including it in a discussion
of the threats to computer/digital systems.
Please reply by E-mail. I will provide a summary to anybody who
requests one.
thanks, - Rob Jackson

"Eavesdropping On the Electromagnetic Emanations of Digital
Equipment: The Laws of Canada, England, and the US" by
