To: info-hams@ucsd.edu I am too, sort of. I am 33, and have been licensed since 1983. I was enthusiastic at one time, got my Extra, got lots of equipment, but also have a family and a job. I would love to experiment with digital modes at 902, but I have to be content to make the multi-DSP card work before Christmas. Besides, I get paid for making the card work so I may be able to buy radio "goodies". I have been interested in radio since the next door neighbor messed up Saturday morning cartoons. He helped develop "tele-text" systems for broadcast TV. He also went "silent-key" last year, thanks to cancer. My other mentors and Elmers have also either left radio or died. There are some hams still on the leading edge, likes of Phil Karn and Cliff Stoll. They are doing ham radio, but also good work on the edge of communications and computer security. Some others are up there, too. (Sorry, don't know all of your names.) Keep posting, your ideas may help bring the dream of others to life. -- Douglas L.

To: info-hams@ucsd.edu All, I'm in the process of trying to get on AMTOR (and hopefully PACTOR once I get the FW upgrade from MFJ) and have had problems while using an Atlas 350 (or 210). I can't seem to link up with any stations on 20 while they're calling CQ (FEC B). I suspect it's the AGC timing of the Atlas (which is not externally defeatable). Can someone tell me if this is common on old rigs due to their slow response time?

Milt's advice is good. The manufacturer's advice for long term storage of NiCd cells is to store them *individually* totally discharged. No chemical activity takes place in a totally discharged cell, so they shouldn't be harmed by long storage. However, if the cells are connected in a pack, then follow what Milt said. You can get a reversed cell as the pack self-discharges in storage. There's always some leakage current in a pack even if it isn't hooked to a load. Recharging every couple of months should keep the pack alive during storage, but of course you're eating up cell life by cycling them.

Don't >know if I misunderstood, but felt I needed to comment. I have a briefcase repeater that I carry with me for boonie ad hoc repeater use and for use at hamfests. The trick to cause the minimum of disruption is to use low power, mine's 2 watts, and use CTCSS access. The biggest no-no is to operate inverted from the bandplan. This can cause real trouble. In most of the country, a UHF portable repeater like this can be a big help at outdoor events while causing almost no problem. However, sometimes there's a local machine on the same pair and you can't use your toy. That's OK, just use the big machine. My portable is on the same pair as my big machine, so when I use it locally I can only jam myself. :-) It turns out to be useful inside some of the big convention center halls where hamfests are held, and where the big machine doesn't penetrate too well for handheld users. It's also useful outside in some of the main repeater's coverage holes. Getting coordination for a portable repeater is impossible. But do use the repeater directories, and *listen* before activating a portable. That in essence is doing your own coordination. If you're upright on the same pair with a distant machine, you won't cause much, if any, trouble to it's regular users as long as your repeater is CTCSS, uses low power, and *your* users do the same. The biggest problem will be your users triggering the distant machine, if it's carrier operated and a bunny rabbit (all ears). The secondary problem may be your machine's output covering the distant machine for some ham near you trying to repeater DX. You should be alert to these situations and be ready to shutdown at a moment's notice if problems arise. To Rick, my portable is a conventional repeater with duplexer, in a Zero Haliburton case with a gell cell, but that may not be the best solution for outdoor use. An alternative is to use two frequency agile radios (a pair of older HTs would be fine), a controller, and separate antennas. With decent spacing, vertical separation preferred, you can have a system you can plop down on any locally vacant pair by just turning a couple of knobs. Retuning a duplexer in the field isn't fun, but a couple of notch cavities can be whipped on frequency fairly easily, and will ease the antenna separation requirements. Low power eases the desense problem too. Using ammo cans to house the radios is a good idea, one radio to a can. That gives the extra shielding you're likely to need.

Perfectly true Steve, but under US rules the work has to be done by a licensed technician, not by the CBer. So asking for instructions on how to make internal adjustments at home is where the problem arises. Now in the perspective of the general lawlessness of CB, this is really a reasonable request, but it got crossposted to the amateur group, and that was inviting flames from the armchair lawyers. In truth, most amateurs couldn't do this job properly to FCC specs because it requires test equipment most of them don't have. Expecting a CBer to both have the skills, and the test equipment, is a bit much. To do the job right, you need a calibrated service monitor and a spectrum analyzer.
