Re: [Repeater-Builder] Re: Can we tuning duplexer with this equipment?
Actually I have had excellent luck with just making sure there is no leakage from the signal generator or cable to the duplexer when using a talkie as the receiver for tuning a duplexer. After carefully tuning the pass adjustments, leave them alone when you have minimum loss and best SWR. The talkie receiver usually has enough sensitivity to dig the signal out of the noise for adjusting the notch. Tune for maximum noise while bringing the signal level up each time you make an adjustment to keep it noisy. My service monitor has too much signal leakage from the front panel and case to accurately tune the notch. I use an old analog Motorola signal generator which has a minimum of signal leakage as the signal source. Accuracy is preserved since I tune the generator to the talkie frequency. Just remember that any signal that leaks from the signal source will probably be picked up by the unshielded talkie and will add to the signal through the duplexer, and will yield the wrong settings for the notch. So carefully shielding the signal source and using good double shielded cable from the generator to the duplexer lets you get away with using a talkie with no shielding. I do use a 6 dB pad connected to the duplexer input and output with a 50 Ohm load on the unused port. If you can put a 50 Ohm load on the output of your signal source and not pick it up with the antenna on your talkie while the generator is set to maximum output, you have a good signal source for tuning a duplexer. 73 - Jim W5ZIT --- On Thu, 12/24/09, n...@no6b.com n...@no6b.com wrote: From: n...@no6b.com n...@no6b.com Subject: Re: [Repeater-Builder] Re: Can we tuning duplexer with this equipment?

[Repeater-Builder] Dropping the Autopatch--Keep 911
In a few days we will be dropping dialtone service to our repeater. However, there is still a desire to somehow dial 911. An archive search of the list yielded no relevant advice on how to use an old cellphone to do this. We have no internet service in the radio room, but there *may* be free/open wifi available. We just haven't looked for it yet. Of course we could run a dedicated full-duplex link to somewhere with dialtone, but seems like a ton of work... If a cellphone (without purchased service) is a feasible solution, which one(s) are good to use and don't require microsurgery inside? What other ways are there? Laryn K8TVZ
Re: [Repeater-Builder] Dropping the Autopatch--Keep 911
Something to keep in mind: If your phone line was only for autopatch, you're fine. BUT if it was also your means of control, you will have to provide another means for that as well.

Re: [Repeater-Builder] Dropping the Autopatch--Keep 911
Talk to your phone Co .. let them know what you need it for .. for 911 if you use the repeater for ARES .. let them know .. I have heard of the phone co doing a DEEP discount on the service or a freebe ( as it looks good on there books) cant hurt to try ... you will have to talk to the VP of customer relations about this ..

Re: [Repeater-Builder] Dropping the Autopatch--Keep 911
So far, all old analog cell phones I have picked up dial 911 without paid service. I call the local dispatcher on them to test this, no problem, so a larger bag phone, generally free and incredibly easy to work on due to their size, could work, a controller made from something like a basic stamp or pic chip could dial for you, send 911, *911 etc to get a connection. Another way is to set your dialer, if possible, to allow outbound 911 only and reject all other call requests. If you go with an analog phone (AMPS), contact your local PD about testing if the service still exists with carriers around you, maybe during off hours. Kurt
RE: [Repeater-Builder] Dropping the Autopatch--Keep 911
Kurt, I'd be very surprised if 800-MHz analog cellular service still exists anywhere. It ended in my area of California more than a year ago. Nevertheless, it's possible that 1900 MHz digital cellular carriers will support free 911 dialing, if certain conditions are met.

RE: [Repeater-Builder] Dropping the Autopatch--Keep 911
Analog cellular was discontinued in Feb of 2009, ATT and Verizon turned their analog off on the day it was permitted-it is possible that some smaller operators are still offering analog but I don't know of any-and ALL cell phones are required by law to be able to dial 911 even if they are not subscribed-the carriers and the public safety folks are trying to get this changed because many people are giving their old phones to their 2-5 year older kids who are dialing 911 because they don't know any better-but analog phones just don't plain don't work on either ATT or Verizon any more-Sprint and T-Mobile never offered analog so if there are any smaller operators out there still offering analog then they might work, but I doubt it.

[Repeater-Builder] Re: Dropping the Autopatch--Keep 911
If you have a standard telephone line and you ask for the service to be turned off, many telco companies will leave the line active and able to dial 911.

[Repeater-Builder] Programming Moto X9000 on a P1
Oh, great wizards. I have an aging, fragile 386sx laptop that has faithfully programmed my X9000 radio for years. I also have a Compaq LTE P1 120 that I program all of my other Moto radios with successfully except for the X9000. On the Compaq, I have tried booting to real DOS6.22 from a floppy (Windows 98SE DOS gives same problem). Using moslo, the X9000 program launches just fine but I am unable to read the radio. I receive the dreaded Serial Bus Failure. Power Fault. message. I can only guess that the computer speed still hoses the serial port despite using moslo to dial back the computer. I have read through all of the repeater-builder and Blenderman sites on the issue. Has anyone made the X9000 program work on a P1? If not, I guess I'm going garage sale shopping. Thanks Mike/W5JR
RE: [Repeater-Builder] Programming Moto X9000 on a P1
Yes. I'm running it fine on a PIII and can read and write with 100% reliability. The trick is to lauch MoSlo twice in a row. I'm using the latest version known as MoSlo Deluxe for DOS. If you are as well then try lauching MoSlo once then launch it a second time. You'll see an odd processor speed show up after the second execution of MoSlo but ignore it and move on to running the RSS. I've tried it on several PIII's with both DOS 6.22 and Win 98SE operating systems (Win 98SE booted to DOS of course) and every one works equally well.

Re: [Repeater-Builder] Dropping the Autopatch--Keep 911
Well, crud... I haven't tested the service in about a year. Best you can do is grab an old analog phone, dial 911, see what happens. If you get a dispatcher, handle it how you see fit. If that doesn't work, try a newer digital one. Since you'd need to get to the keypad for your mod, use a large phone, you can couple acoustically to the speaker and mic, though most of the ones I've scrapped have contact pads for the speaker, easy to solder to, and the mic, usually surface mount has two small tabs sticking out from under the assembly, not too difficult to work with.

Re: [Repeater-Builder] Programming Moto X9000 on a P1
When you first turn the computer on it will usualy say something like press F5 for boot screen, do it and go in and see if there is a setting for slower processor speed. Select slow speed and also disable the cache . I have to do these two steps with my Toshiba Satalite and it works fine on my x9000. Moslo never worked for me.
