Yes, FMN is an option on some amateur rigs, but not all.

Re: [Repeater-Builder] Re: Trbo to be DOA 2012 Say Hello to Tetra
Mike, I see your point for the commercial side, but how many amateur groups are going upgrade firmware on a repeater after it is up and working? How many are going to upgrade firmware on a machine that doesn't need it before they put it into operation? But there is plenty of non software equipment still out there that will eventually be surplus, and as for the firmware/software upgrade to remove 25KHz, I don't see it happening (at least not from Motorola) when the manufacturers can make more money selling new equipment as opposed to a firmware upgrade. Just my .02.

Re: [Repeater-Builder] RAIN Report: KT1B Commentary on Green Petition to Ban Closed Repeaters
Dave, I think Murray has an issue with repeaters that have a PL but not advertising the pl in any of their announcements. I'm not aware of any closed repeaters in Metro DC either, but I am aware of several with PL that do not have it on the ID/Announcement. As for GMRA and PL, they have a transmit PL on the repeaters and the members can activate receive PL on their radios so as not to get any bleed over from other repeaters on the same frequencies.

Re: [Repeater-Builder] P25 (mis)Information?
Most if not all P25 radios (both portable and mobile) have the ability to do analog and digital communications from the same radio. While most can receive both analog and digital communications on the same channel if set up for mixed mode use, I am unaware of any that can transmit on both analog and digital on the same channel. All radios only have one vocoder, for P25 that is the DVSI IMBE vocoder. It is the same vocoder used by all the manufacturers and DVSI is the only producer/supplier of the vocoder. Thus any manufacturers radio set for P25 should work on any other manufacturers system since P25 is a standard. I know from personal experience that Thales/RACAL, motorola and EF Johnson radios all talk to each other when in P25 as I have several of each and enjoy playing with them. (now if I could just get this VHF Quantro up and working) So I would guess that the gentleman from M/A-COM was from marketing and not a technical person and just spewing marketing crap (no offense to those that use M/A-COM) and i would ask to talk to a technical person for any article. It has been recommended by many organizations, including APCO, that when on fire ground (scene), any department that has a digital system should revert back to an analog system for firefighter safety.

This is just another great benefit of EDACS technology...It is able to provide both digital AND analog features. For Fire, we plan on programming all of their radios with an analog on-scene talk-around group in addition to all the other talkgroups as an added feature in the event it is preferred in those particularly noisy environments. There have been some cases reported like the one in Orlando with P25 systems, since the systems only offer digital technology and does not have the capability of using analog. All P25 vendors including M/A-COM and Motorola are aware of the issue and are looking for ways to improve the technology. Without getting into all of the technical reasons, a lot of it has to do with vocoders. P25 technology in general uses less vocoders and therefore can sometimes leave out some of the audio. EDACS technology has not had a significant number of complaints from Fire Departments as the technology uses more vocoders. I am trying to find a technical explanation to send to you as well.

During a recent supermarket fire, firefighters were forced to use their old radios to communicate because the new system was distorted. Noise was the problem. Warning bells on firefighters' air packs cause microphone distortion on digital signals much more than with analog channels. We keep on the analog tracks so that we have the clarity that we need. So, like I said, get the bugs worked out in the digital system, said Fire District Chief Keith Maddox. The digital radio channels are also hard to hear when the firefighters are working next to trucks because the engines have to be revved to pump water. Fire departments nationwide have known about digital signal problems for over a year, but Orlando's fire department thought that the bugs had been worked out. With this one, we didn't know the problem was there until recently for us, said Fire Chief Jim Reynolds. So they conducted a test that proved the new channels were too hard to hear.

The framing/encapsulation of that AMBE in a P25 or D- Star overall bitstream is completely different, but if you can figure out how to copy the frames, you can extract the AMBE bits and shove them through DVSI's CODEC to get audio, and vice-versa. Not according to DVSI, they have several flavors of AMBE (AMBE-300, AMBE-2000, AMBE-2020, AMBE-20x0-HDK, AMBE-1000) and not all of them are AMBE+2 compatible, so AMBE is not AMBE especially when talking AMBE and AMBE+2. If they use the same compression scheme and chipset then a dongle shouldn't be a problem, if they use different chipsets and schemes then I guess the question is how hard would it be to come with a Dongle for P25, since one already exists for D-Star?

Early Motorola digital radios were sold with Motorola's Astro proprietary digital voice format which uses the VSELP VOCODER. After APCO released the P25 standard using the IMBE VOCODER, Motorola offered that as well. Both were available for a period of time. Subseqently, Motorola has discontinued their original format. In Motorola terms: Astro = 9600 BPS C4FM digital voice using the VSELP VOCODER. Astro25 = 9600 BPS C4FM digital voice meeting the P25 standard and using the IMBE VOCODER. Purchasers of used Motorola digital radios [Astro Spectra, Astro Saber, and XTS3000] must be careful that the radio they are buying has the features and VOCODER they want. Newer Motorola digital radios [marketed as Astro25 products] such as the XTS5000 and XTL 5000 were never sold with the old Motorola VSELP Astro format. As to whether Motorola Astro VSELP can be used on the ham bands - it is simply a digital voice format with no intent to obscure content, so it probably would be OK, but why would you want to utilize a dead format? --- --- In Repeater-Builder@yahoogroups.com, Dan Blasberg [EMAIL PROTECTED] wrote: Since when isn't VSLEP allowed on the ham bands??

Re: [Repeater-Builder] Re: Making room for the new guy - repeater coordination - Hope this is not too o
No, D-Star does not automatically switch between analog and digital. You have to have one channel set up for analog and then if you want to do digital on the same frequency, you have to set up a digital channel. P25 can monitor both analog and digital in mixed mode operation but only transmit in one or the other (so you need to channels on a P25 radio as well for transmit purposes.

Re: [Repeater-Builder] Repeating D-Star
Steve, No more than for a D-star capable rig, either mobile or portable. Used Astro Sabers go for anywhere from $150 for a basic 16 channel model to $700 for a full blown 255 channel model with display and keypad. EF Johnson 5100's can be had for about $500 used (and they are front panel programable through a menu!). Mobiles are a little more, but also have more power and better receive front ends than any amateur radio will ever have (at least until they get rid of wideband receive). The repeaters are about the same or less than a D-star machine and are made by several manufactures, and the bonus is, that a repeater in mixed mode can still be used by amateurs with non-IMBE equipment to talk to each other. It all comes down to what you want to spend on the equipment, just like everything else with this hobby of ours.

Re: [Repeater-Builder] Repeating D-Star
It shouldn't cost anymore for an IMBE P25 board to be added than for the AMBE D-star add-in boards. Different Vocoder, but the licensing from DVSI for the manufactures should be the same. All of them have the ability to do IMBE on the commercial side, so it shouldn't be that difficult or expensive to do it on the amateur side. For that matter, put both vocoders on the same board and have a radio that you can do conventional (analog), D-Star, or P25 on the same frequency at the touch of a button. Put that on your wish list, and I like the idea of bringing it up with the reps at Dayton. I may have to mention that to the rest of the group I am going with that will be on P25 at Dayton.

Re: [Repeater-Builder] Repeating D-Star
VSLEP, AEGIS and Pro-Voice aren't any different than D-Star is at this point and can be used just as any other digital mode on the ham bands. You just have to have another radio programmed for that protocol to receive it. Under that logic, the AOR Digital voice units should not be used on the ham bands because they only work with other AOR units (not an open standard).
