Table I. These are jus i a few of the available programs for the BayPuc BP-2M and BaxCom modems. The only definitive commercial package is the BayCom 1.6. Haven't tried it. The authors of most of the programs have only run them on a few computer*. Sometime* they work for one person and not another. Everything is written by hams who have real jobs to keep the wolf away —so you work with what you find that works for you.

the documentation for the Ham-Comm shareware program gives a schematic and parts list.

The challenge comes in writing the software to do the job, I here is a great effort being expended in Europe to write such software -and it seems to be

equal to the work on this side of the waters that goes into the design and refining of mult ¡mode hardware and sophisticated software for alt the other digital modes.

Some of I he problems I have encountered are related to my own hardware and my local packet BBS, i have nut found explanations for some of the problems, but there are some combinations that work, t have been focusing on a portable digital station based on my IBM laptop. Some of the bells and whistlesofWindows953M tend to stifle progress.

Tin using the newer laptop because I have other uses that require Windows-based programs. However. 1 have come across warnings ihat some of the earlier DOS-based laptops also offer resistance to packet operation. This means to me thai we still have an experimental hobby situation.

Some new news

Just as 1 was wrapping up the thoughts for the month. 1 un>k a look ai my E-mail and found a posting from George SV2AGW on osie oftheTAPR newsgroups, 11Lh claims to have developed a driver for the BayCom that allows any Windows 95 terminal software to function just as if using a regular TNC.

George conveniently left □ clickable [http://www.forthnet.gr/ sv2agvj embedded in the message. 1 couldn't resist taking a look and found some good information along with several programs. I downloaded the driver and his terminal program There won t be time to install and te>t it before i send this off, but t will t:ike it with me when I go out of town next week. In a true gesture of ham goodwill, George is offering his programs as freeware! Now, that is an incentive.

[ mentioned so mam programs this month and earlier for ihe Ba\ Pac BP-2M that I put them in chart form (Table 1) so you can have reads reference] There are more out there. Just check the TigerTronics™ Web page. I just lisied the ones I have tried or intend to trv.

If 1 can put this month's column inib proper perspective, that's what 1 like about ham radio, You echo work on it until it works—then, when it does and you know you did it yourself, you get your well-deserved Lhrills. A

digital connection to a station on am it her continent or a node across town always brings that little tingle about sophisticated equipment i ha! works because you made it do it.

Speaking ol thrills. I now have a laptop that, with a few keyboard calisthenics, I can use to make a packet connection wherever I travel. For mc, that provides a little excitement every time I see it work. Not world-shaking by today's standards, nut something I didn't ha\c a vear ago. I still haven't mastered all the bells and whistles available from my BuyPac BP-2M but that gives me something more to look forward to.

Ham mdio, by its vers nature, gi\es each of us something to look forward to, thai we can accomplish on our own—or if not. wiih the help ol a ham friend. That's what iTs all ahotil.

If you have questions or comments about this column, E-mail me at ihe address in the column heading and/or CompuServe 1721 30.13521 i w ill gladly share what I know or Hilda resource for you. On packet, when you gel a chance.drop me a line [KB7NO @ N 7N PB t#N( )N F. V. N V. USA. NC )A M ]. For now, 73 Jack K137NO.

A bright spot in your day

Here's another workbench pinup thai you might want to keep somewhere handy, a simple LED limiting resistor chart. Table 1 shows the chart, which probably needs little further explanation. Most light-emitting diodes (LEDs) require a properly chosen current-limiting resistor to keep them from scif-destrueling, which can occur almost immediately if the resistor is inadvenenily omitted. The values in Table I, however, can act as a quick reference to the proper size of resistor for supply voltages from three voits to 12

volts, using standard-resistance

values and keeping the LED forward current at about 10 to 12 milliamperes (which is safe in the majority of devices). Some LEDs can handle more forward current (20 to 25 mA)t in which case the value shown can be cut in half. Others may perform better with less continuous current (5 or fi mAK in which case the resistor value shown can be doubled. On average, however, most currently made LEDs seem to work nicely with the exact values depicted in the chart at ihc various supply voltage levels shown.
