On Apr 12, 2008, at 6:28 PM, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I hate the fact that I’m announcing this, but I’m looking for some assistance with PIC, STAMP, whatever programming and learning how to read what some one else already put on an IC. At a club meeting a few years ago, the pres at the time did a presentation about PIC microcontrollers and gave a demo. He showed us that it either was 64 lines or pages of code to turn a little LED on and off with a momentary push button and I thought was a waste of time to put that much effort into perform such a simple task…. Open mount, insert foot. (how many lines of code do you think the ASIMO programmers have to write to make it the damn thing turn it’s head one degree?) Why do you hate it? You're just asking for help with something new. First, I'll say that for my taste you're going about it backwards -- you need to decide if the phones you're using can even be brought into the ham bands by analyzing and controlling them manually and measuring their performance in the band, before worrying about how you're going to control their features/gadgets. If the RF deck in the phone wasn't designed for the ham band, you have some serious modifications ahead of you and studying of the components on the board and the service manuals to even see if the device will go to ham frequencies. I wouldn't even THINK about working on the digital user-interface or control circuits, until you know the basic RADIO will do what you want. But, with that said... I'll move on to microcontrollers and such. What he was probably showing you was programming the PIC microcontroller in Assembly Language. Every single thing the chip does is accessible to you at this low-level language, down to individual bits and any low-level math functions. (When was the last time you did mathematical division -- for example -- by writing a loop that looked at an individual address spaces holding two numbers represented in binary, and then did addition (or subtraction -- which is really only backwards bit-wise abddition in CPU's) to individual bits at a time, while also having another loop moving in and out of memory locations using an 8 bit binary scheme? That's low-level Assembly programming! Remember, digital logic is at it's lowest- level, just a giant bunch of transistor switches that can be set to on or off... 1 or 0 in programmer's language.) Writing in Assembly is both old-school these days, and also the only way to learn it right, so to speak. But... with that said, there's PLENTY of people who've never programmed a microcontroller in a low-level language like Assembly. They'll never know if the program the high-level language's compiler is right nor can the tell if it uses the chip in the most optimized way, saving the VERY limited program memory and on-board flash on these tiny little processors -- but with higher level languages you can write code for microcontrollers in BASIC, C/C++, etc. There are also some people who've written complete special languages that make it easier to write simple code for a microcontroller. There are a MULTITUDE of 8-bit and larger microcontrollers on the market nowadays. Most hobby applications use the Microchip PIC and/or the Atmel AVR types, but there are others... each specializing in market niches. Both Microchip and Atmel have cheap/non-production programmers that often double as in-circuit serial debuggers when using the right chips (a feature where the chip supports special instructions where the developer can literally step through his low- level code one line at a time and see what the circuit does *IF* you used their free Assembly language/C tools.). A couple of places to start: Of course, the manufacturers: http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGEnodeId=74 http://www.atmel.com/products/avr/default.asp (Those are the links for only the 8-bit microcontroller products, both companies now have product lines all the way up to 32-bit architectures.) Community sites: http://www.piclist.com http://www.avrfreaks.net http://forums.microchip.com I originally stopped programming in Assembly in the 1980's, and then came back to it in microcontrollers much later, for fun -- other than messing with the types of things you mentioned above, blink an LED and the like I didn't really do a whole lot productive with them, but it reminded me of the simpler days of computing... when all you had was an 8-bit microprocessor and a very tiny amount of RAM. Today, to accomplish things in a reasonable amount of time as a hobby, you have to realize that the amount of coding effort to make a microcontroller (without an HLL or... high-level language) is not trivial! If you're unfamilar with microcontrollers, you'd better lay out a plan to work through things like blink an LED and build that

Re: [Repeater-Builder] DB-224 problem
I once inherited a DB-224 that the shop had discovered was not performing as it should. A new antenna fixed the coverage problem the first antenna had. When I got the antenna, I discovered that one of the elements had been inverted. When I installed the antenna I turned that element back to match the other elements and it worked just fine. As an aside, I helped a buddy build a couple of six meter four element beams and when he installed them, the performance was miserable. When I got a look at the installation I could tell that the gamma feed on one antenna was on one side of the boom and the other side on the other boom. When the lower antenna was flipped over to match the upper antenna the stacked beams worked fine. For the pattern of the individual elements to sum properly at a remote site for these types of antennas, the elements must all be fed in phase. Inverting an element or reversing the gamma feed causes the elements involved to be out of phase with the other elements in the antenna. 73 - Jim W5ZIT R. K.

[Repeater-Builder] S-COM 7330 Triple Repeater Controller
Hi All, I'm very pleased to announce that after nine months of beta testing, the new S-COM 7330 Triple Repeater Controller is in production and available for sale! A total of 66 units were tested by 54 repeater owners, and the results fed back to the design team of five engineers (four of whom are hams). The resulting five code upgrades added features and fixed minor bugs, and were found to be easy to install in flash memory via the high-speed (57.6K) serial port. (My personal and quite biased view is that this thing is heads and shoulders above any of our previous controllers, extremely competitive, and only in its infancy due to the large amount of available memory -- and matching wishlist of future improvements... :-) We're calling it a triple repeater controller to differentiate it from three port controllers that cannot operate three repeaters totally independently. That is, the 7330 will run three repeaters, links, or other radio configurations connected in any fashion, as you'd expect. But it can also send different messages (CW, digitally recorded audio, beeps, or paging tones) to all three transmitters at the same time, have different access modes for each RX-TX path, and much more. In fact, each repeater will think it has its own controller, since there's three of everything -- three DTMF decoders, three dual-tone CW/beep/paging generators, three digital audio players, three CTCSS encoders with reverse burst, three digital audio delays, and plenty of additional features. We've placed the V1.0 user manual, schematics, a white paper on the design philosophy, and other materials on the website, _www.scomcontrollers.com_ (http://www.scomcontrollers.com) , for all to peruse. Oh, yeah, the price: $459 plus $15 for shipping, and that INCLUDES the 1U rackmount cabinet with a 28-LED display.

[Repeater-Builder] Re: DB-224 problem
Below is some information on the antenna setup. As I said earlier, I have one element upside down. I do need to know one other thing! Around the pole I have the elements at 90 degrees from each other as this is a top mount and not on the side! Is this a problem?? The antenna is top mounted on Rohn 45 tower and the elements spaced at 90 degrees from each other around the pole. Spacing going up the pole is according to the diagram from the files of this site. Factory harness which measures out ok for the band and has markings of 11 and I think maybe 83 which I suppose indicate 50 and 75 ohm cable. The antenna is used but I have checked all connections and fittings. I will change the element around on Monday but for some reason I am second guessing myself on the 90 degree turn. Should it be 180 degrees and is so which elements line up? My knowledge is limited when it comes to antennas.

Re: [Repeater-Builder] Re: DB-224 problem
Orienting the elements as you have indicated is fine - like North, East, South, West (except they don't have to actually point those compass directions). I remain concerned about the resonance and VSWR. It will be interesting to see if flipping the upside-down element fixes this problem. I won't be surprised if it doesn't, but for your sake, I hope that's all it is. You didn't say what kind of feedline and how long the run is. I'm assuming that the VSWR reading was taken in the shack. However, if there's a lot of line loss, and the VSWR was taken on the ground, you could actually have a worse VSWR than you think.

[Repeater-Builder] Re: DB-224 problem
All DB224E's that I have ordered many years ago, were Offset pattern (all elements on one side of the pole) and none required assembly except plugging one 12ft section into the other, tighten two radiator hose clamps and connecting the center phasing harness connectors together and weatherproofing. Order just a 224 and you get elements at 90 degrees from one another. This is good for Top mount on a tower, for side mount you want the antenna at least 2-3feet from Rhon 25 and 4- 5 feet from Rhon 45 if you are looking for a mostly Omni pattern. Offset on a side mount gives you a killer 12db frontal lobe with a 3db backlobe, as was originally on the first Sawnee Mountain Machine I built way back in the late 70's. Never had inverted emements, hot side was always up. Good Luck Steve W4CNG

[Repeater-Builder] Old Motorola RSS without a 486 PC
Fellow Builders, I don't recall hearing about his here. I did not check ancient archives, please don't flame me if you all know about it already :) Tonight I successfully programmed an OLD Radius SM50 with OLD RSS that requires an OLD (like 486 or thereabouts) PC. I've heard there are a lot of older RSS packages that weren't updated to run on newer machines. Realizing that gamers had the same issue, I started seeking out old PC gaming emulators and found DOSBox. It works like a champ. How well does it work? I did the programming from my Mac laptop using the OS X port after trying it first on the PC. Hope that helps someone somewhere along the line. 73 DE N0MJS -- Cort Buffington H: +1-785-838-3034 M: +1-785-865-7206
