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.

S> S> Cheers de Sandy WA6BXH/7J1ABV WA6BXH@N0ARY slay@netcom.com 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. 73, Jack Anderson N4ULS ------------------------------ Date: 6 Feb 1994 21:08:33 GMT From: pacbell.com!sgiblab!sdd.hp.com!math.ohio-state.edu!howland.reston.ans.net!EU.net!uknet!bhamcs!news@network.ucsd.edu 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 (more information on TEMPEST can be found in the paper "Eavesdropping On the Electromagnetic Emanations of Digital Equipment: The Laws of Canada, England, and the US" by Cristopher Seline - available on FTP from csrc.ncsl.nist.gov) ------------------------------ End of Ham-Digital Digest V94 #29 ******************************
