Re: [Repeater-Builder] Wide Area Coverage
Steve, I think this is what is misunderstood by most repeater owners and users is that D-Star has set up a system that is not only digital voice, but a gateway for interconnecting them for those who wish to connect into the system. It is more like analog repeaters connected into a chat IRLP or Echolink, but with better full duplex connectivity. My interest in D-Star is the digital voice. From a number of commercial and Ham users it seems digital has a much more fad/multi-path problem. Know the world is going digital, but for mobile applications seems to have some problems.

Or imagine the same for about 2500. That's IRLP today. ;) I do suspect that the D-Star systems available will continue to grow, but it's unlikely that it will every achieve the penetration of IRLP or Echolink. They are a bit different, althought IRLP is very similar except that you can set it up for about $100 and an old radio. I think it will be more interesting as other manufacturers begin to offer D-Star and begin to drive the cost down. Chuck - N8DNX On Sun, 18 Nov 2007, Steve S.

[Repeater-Builder] Micor UHF PA control line question
Hi All, I have an application were I am using a 10 watt GM300 to drive a Micor 75 watt PA. I have a couple of concerns about this and I thought it would be better to ask the group than to blow up the PA and the GM300 (good idea, right?) I set the GM300 for 1.5 watts drive (Is 1.5 watts ok for a 0-10 watt GM300?) I connected the control line to A+ ( the book says 6-10 v, but I've told this is OK, I question that logic.) Keyed up, 105 watts! Turned GM300 to 1 watt, got 90, 3/4 watt got 80! OK, I'm blowing smoke, but I'm afraid of white smoke in cabinet! I would like to get this drive back to 1.5 -2 watts (protect the GM300 and prevent spurs) and get this PA back down to 70 watts Any easy way to control the control line? I'm missing something easy here, so flame suit is on! 73, Brian ** See what's new at http://www.aol.com
Re: [Repeater-Builder] Micor UHF PA control line question
A couple of ideas: 1. Build a simple voltage regulator capable of the current you need for the controlled stage. I think about a couple of amps, but you could insert an ammeter and actually measure it. Set your radio to 1.5 watts and then set the voltage to whatever gives you the desired output. 2. Build a 3 dB pad capable of 5 watts or better. The easiest way to do this is a coil of RG58 that is about 30 ft long. RG58 has about 1 dB per 10ft loss at 450MHz. Then you could set your radio to 2.5 watts out, and your amp would see 1.25 watts. Then attach your controlled line to 12v, and set your output power by the GM300 level. The GM300 should work fine at any level above a watt or so. Joe --- [EMAIL PROTECTED] wrote: Hi All, I have an application were I am using a 10 watt GM300 to drive a Micor 75 watt PA.

I would like to get this drive back to 1.5 -2 watts (protect the GM300 and prevent spurs) and get this PA back down to 70 watts Any easy way to control the control line? Why not skip the first two stages in the Micor amp and drive the driver stage with your GM300? Then you can just adjust the GM300's drive to get the final TPO you want. IIRC, the driver stage is normally around 8 watts input, 25 output, which then feeds the four finals in the 75 watt PA. Check the manual to confirm those power levels. Very important: there is NO HARMONIC FILTER in a UHF Micor PA - it's outboard in the antenna network within the Micor station chassis. If you're going to use that Micor PA standalone, put an isolator and a good low-pass filter on it. Along the same lines, keep in mind that the 75 watt rating is after the antenna network (isolator and harmonic filter); the PA's output is normally in the 90-95 watt range before the antenna network. --- Jeff

YMMV. You just have to do some hunting to find the right values for amount of attenuation and the average power level the attenuator can handle, since the loss is all turned to heat. Inline attenuators also come in super-handy (as do tee connectors with variable coupling) for tuning up receivers and/or protecting a receiver from an overly aggressive pre-amp. :-) I see these things and hamfests and snatch them up, most people don't know what they're used for and/or don't know what they're worth, even on the used market... they're not always that cheap. I know, I know, everyone's got one of those I found this great deal at a hamfest stories... and not everyone can find that same deal. But it's definitely worth keeping your eyes open for these things as you start to build systems. You start to figure out what the hard or expensive components you MIGHT need are, and then you start to fill your basement with them -- and your wife just shakes her head and smiles, as long as you keep it all in the back corner where no one will see all of it. (GRIN!) Dayton often is the best place to shop, of course. I've only been to Dayton once, and saw so many things there I'd love to have handy back home just in case I needed it that I had a hard time not blowing the budget I had set aside for myself. Hunt the junk boxes at any hamfest you go to -- sometimes there are good deals on what are otherwise small and easy to lose parts like in- line attenuators, just waiting for you at the bottom of some guy's box full of utter junk. :-) -- Nate Duehr, WY0X [EMAIL PROTECTED]
[Repeater-Builder] FS: Kenwood PG-4H cable
For sale: Kenwood PG-4H cable. Brand new in its package. This cable has an 8-pin round mic plug on one end (like the MC43 and MC60 mics), and the other end has an 8-pin RJ45 style modular plug. The cable itself is about 5ft long, and is a straight conductor. This cable was originally designed to interface the TM-X31A series mobile radios to a RC-xx multi radio controller. Almost like an early TM741 or Icom 901, whereas the radio were used as band units, and the controller controlled them all remotely. This cable is also the cable used to interface that series radios to the Doug Hall RBI-1 repeater remote base interface. Thus the reason I have one left over from the days when I had the RBI-1 (long gone), and the reason for posting on repeater-builder. $18 shipped USPS Eric KE2D

[Repeater-Builder] FW: Rogue cell phone has 911 on redial
Just wondering, I hope this is not an amateur repeater placing a 911 call with an old bagphone... _Ray_KBØSTN November 18, 2007 5:30 PM CST A rogue cell phone is not accepting calls, but it sure likes to dial 911 operators in eastern Iowa. Operators at the Black Hawk County Consolidated Communications Center said that they received about 400 calls from the same cell phone last week and that no one seems to be on the other line. That's it right now, said Dispatcher Chuck Hosier, as a phone rang in the background. It will ring in, and it's an open line. Sometimes it rings in and drops off. Officials can't locate the phone but have figured out that it is an old line not currently associated with a cell phone provider. Such phones, once charged up, can still place 911 calls under Federal Communications Commission rules set in 1994. The cell phone can't receive calls, and emergency workers haven't been able to track the owner through service records, either. With this, we are pretty helpless, said Judy Flores, the center's administrative supervisor. Officials are suspicious that it could be a prank - but they say it's not funny and potentially dangerous. Until the source of the calls is found or they stop, dispatchers still have to answer every call just in case someone is on the line with an emergency. Copyright © 2007 The Associated Press.

Re: [Repeater-Builder] Wide Area Coverage
Couple of big differences between D-Star, IRLP and Echolink: With Echolink, any licensed amateur with a soundcard-equipped computer and an internet connection can connect to an Echolink-enabled repeater. With IRLP and D-Star, you can only establish a connection between repeaters over the air - there is no access from the internet side. And for now, only an Icom D-Star radio can connect to a D-Star repeater (yes, I know about the dongle, but it's not commercially available yet nor easily replicated), while any rig with a touchtone pad can dial up an IRLP link.
