To: ham-digital@ucsd.edu After reading many posts regarding the unfairness of the code requirement and the elitism of CW ops, and superiority of one mode over another, I suggest an alternative. First: A) It is a given that the ARRL will not support ths and i honestly hope that i am wrong. B) An influx of new hams is taking place and many of these operators are interested in digital modes. C) The future of amateur radio is getting licensed now. with that said, here 'tis. The usenet r.r.a.?? newsgroups constitute a watershed of hams with a de-facto interest in digital communications and radio-theory. The opinion of these participants vary widely (as evidenced by the constant bickering!). These factors combine to provide a forum for the development of a proposal for the modifications of the current state of HF spectrum management. Proposed Alterations: 1) Novice Priv's to include digital-specific allocations, for example: 7075-7100; 14075-14100; similar allocations on one or more WARC bands. 2) Generation of an additional written exam, specific to the theory, implementation, and practice of digital modes. Coverage of data types, data rates, modulation techniques, bandwidth, hardware, on-air protocols, Propagation, RFI. and FCC regulations is expected. I believe that the resulting impact would be to avail a large number of hams of spectrum prioritized for digital modes. This would be in keeping with the "technology infusion" theme of the no-code. No-code Techs are REAL hams with strengths that have nothing to do with triodes and air-variables. WARNING! Flame Bait Ahead.... Q. How valid is a technology that is undergoing a spare-parts shortage? ASIC's and microprocessors are cheap, reliable, versatile, and were developed to REPLACE tubes, crystals, hartley oscillators, and the like. Forcing 75 year old technology to be the yardstick for amateur radio places the future of the hobby in jeopardy. Ahem.... If the energy of the Usenet participants was directed to change, the potential exists for a shift forward in the status of Ham Radio.

Would that be legal...? 1. Yes, this is possible, legal, and is done all the time. 2. You must be a licensed radio amateur to use the amateur portion of the 2 meter band (or any other ham band, for that matter). 3. Commercial communications are prohibited on the amatuer bands, so such systems are limited to personal (i.e., non-business) use. The bottom line is, if you want a cellular phone, go out and get a cellular phone; they're lots and lots cheaper than the equipment you would need to set up the system you suggest. If you are interested in ham radio, great, but there's a lot more to the hobby than just portable phones. Contact the American Radio Relay League in Newington, CT, for more information on becomming a ham, and for the name and number of a ham radio club in your area. There's lots of friendly hams who will be happy to help you earn your license and get on the air.

To: ham-digital@ucsd.edu I recently uploaded the latest version (2.1) of the SimpTerm program to both SimTel and garbo archives. Look for the official announcement on comp.archives.msdos.announce news group. SimTel/msdos/hamradio/ simptr21.zip Generic TNC comm program (packet, rtty, etc) I think it will be in the ham subdirectory on garbo. It replaces simptr20.zip, version 2.0 of SimpTerm. Version 2.1 of SimpTerm. SimpTerm is a simple terminal program designed to be used with almost any tnc or tu on the market. Features of SimpTerm are: o Split window operation. o Macro key definitions. o User customizable Help screen o Most of the non-ascii keys can be used as function keys o Optional scroll back feature on the receive window and trans- mit windows o Simple status display in the middle of the screen o Capturing of data to a disk file o Access DOS commands without dropping communications connection o Control of the com port definitions from command line, init file and keyboard. o Works on 8088 as well as 80486 and everything in-between. o Status line o Small enough to work well on resource tight platforms, like laptops. o Selcal functions, limited unattended operation. o Times can be in GMT or local time. o A station logging function. o User selectable color scheme o Automatic "cq" operation (or any other repetitive transmission o Function keys and control keys can be assigned to a macro string, cause a file to be uploaded or call a function within the program. There are loads of programs that are tailored to specific tnc's and there are dozens of good terminal programs that can control any tnc in a "dumb" (that's a technical term) manner. This program is an attempt to provide the average ham with something in-between. It has a lot of features, but not so many as to make use of the pro- gram or the tnc hard. It requires you to know the commands of your tnc, but also gives you the flexibility that only direct commu- nications with a tnc can provide.

To: ham-digital@ucsd.edu !!! HAM RADIO AND TUBE STUFF NEEDED !!! 1. I am in search of the following item: 7N7 locking octal vacuum tube for a 1946 era television. This request is a relay for another ham who does not have Internet access. If you have one, please contact me. See contact points below. 2. The Tufts University Amateur Radio Club, W1KN, Medford, Mass. is in the process of putting together a digital communications network. Their ultimate goal is to permit someone who connects to be able to jump out to anywhere else - say, to Canada, or Chicago - wherever! They also plan to interface the network to the Internet! In order for this to work, equipment is needed. Their cash has been depleted, so any equipment they do get is via donations. Also, since their cash is gone, none of it is insured. If they get a lightning blow, and it all goes down, or if anything is stolen or fails, it's down. On behalf of their club (I am assisting), I am asking for donations of ANYTHING you can offer - radios, coax, connectors, cash for equipment and/or insurance for the equipment, computers, TNCs, you name it.

John B john.boyer@rd.eng.bbc.co.uk ------------------------------ Date: (null) From: (null) Subpart C - Special Operations 97.201 Auxiliary station. - (a) Any amateur station licensed to a holder of a Technician, General, Advanced or Amateur Extra Class operator license may be an auxiliary station. A holder of a Technician, General, Advanced or Amateur Extra Class operator license may be the control operator of an auxiliary station, subject to the privileges of the class of operator license held. (b) An auxiliary station may transmit only on the 1.25 m and shorter wavelength bands, except the 431-433 MHz and 435-438 MHz segments. So it looks as if 2 meter operation is out. And, of course, one would have to be very careful not to make business phone calls. See part 97, section 97.113. And, you're responsible for anything that goes through your auxiliary station, so be careful to set it up so only you can use it. It's a good idea to browse through part 97 any time one decides to do something like this. Any remote control operation requires care to make sure you retain control and meet the legalities. Good luck!!

(Maybe it's me.) I have understood the following to be correct. Someone correct me if I am wrong, please. 1) The NPRM allows HF semi-automated qsos to take place in all digital subbands. 2) semi-automated operations is when a distant station can intitiate contact with a remote station by keying it's selcal/callsign on a frequency on which the remote, possibly unmanned station is located. As is currently done in initiating Paclink/Aplink contacts now. 3) Under this process, the remote station (generally a BBS) will not listen before transmitting, but the other end of the qso, which will be a human, of course, is supposed to. Let me know if I have misunderstood.
