Re: [Repeater-Builder] ctcss logic back to an external repeater controller
The new RLC-DSP404 supports CTCSS and DCS decoding and encoding standard. Allan Overcast KF7FW Link Communications, Inc. www.link-comm.com Nate Duehr [EMAIL PROTECTED] wrote: skipp025 wrote: ctcss logic back to an external repeater controller I've been talking with a small number of people off the group about external repeater controller interface logic lines. In specific how many of the external repeater controllers handle ctcss (sub-tone, aka PL) detection, logic, control and selection. To keep things short and simple... let us assume an example of the two most common repeater controller layouts regarding ctcss operation. I'll see your two examples and raise you one, Skipp. (GRIN! Or maybe 2...) Example 3: At least two controllers now support CTCSS detection and/or generation directly in the controller. The S-Com 7330 (currently in beta test) offers CTCSS encode, but not decode: http://www.scomcontrollers.com/ The PSE-508 series from Pion and Simon Electronics handles both encode and decode, but is built to be installed into a specific repeater, the GE MASTR II. (In fact, their latest software rev offers 4 CTCSS tone community tone panel-like functionality.) http://www.pionsimon.com/products.htm Wasn't there also a Pacific Research controller that did one or both of these at one point? They've always been too expensive for me, but I thought one of their boxes did it... maybe... ? I think putting the encoder/decoder up in the controller is the wave of the future... if done right, it should make things a lot simpler in the long-run... no fussing with CTCSS boards in any fashion, just bring discriminator audio to the controller and find a place to send audio back that isn't high-pass filtered... done deal... The controller folks making the CTCSS circuits have to go out and get an edumacation on Reverse-Burst/STE and all that fun and games though, if they want to fully emulate the original manufacturer's boards... I know the 7330 is going to have the option to do either type of phase shift on their encoder, for example. Not sure if the PS does RB/STE at all. Example 4: Go digital, leave the silly CTCSS behind. The 70's are calling and they want their repeater back! Heh heh. :-) :-) :-) !!! Nate WY0X - Boardwalk for $500? In 2007? Ha! Play Monopoly Here and Now (it's updated for today's economy) at Yahoo!

I will forward this to Steve to answer. Allan Nate Duehr [EMAIL PROTECTED] wrote: I'm probably not the first person to mention this, Alan... but... If you made changes to the source of any Gnu Public Licence-licensed (GPL) binaries from the original authors, and recompiled new binaries, you're required to make those changes available under the terms of the GPL. (Making them available doesn't mean you have to put them on the web, the full terms are in the GPL itself.) Hopefully you've carefully reviewed the source licenses of any code modified to produce new binaries (if any of the binaries were modified) on the system, and are either planning up-front to release all of those changes, or have written permission from all authors and copyright holders (sometimes very hard to determine if multiple people have contributed to something before it made its way to you). Having been involved in reviewing this requirement with IRLP and Dave Cameron many years ago, he avoided the problem by only modifying one binary that he didn't write himself. That binary was released to the Public Domain and wasn't under the GPL, and everything else on the system was written from scratch... so no problems for his system. Drivers for the kernel are also sometimes a different story -- they might be dual-licensed under the GPL and the LGPL, which changes the rules somewhat (but not much), and many tools on so-called Linux systems are actually licensed under the BSD (Berkeley Systems Division) licenses which allow much more room to make commercial products without releasing source code. Just mentioning it because a lot of very big companies (Linksys, Microchip, others) have fallen into the Linux licensing trap and were forced by the Free Software Foundation to release their modifications to the original GPL-licensed source code. You probably knew all of the above, already... but just mentioning it... Embedded Linux can be a pain in this regard, which is what drove Linksys to move to VxWorks for their small routers. By that time, people had figured out how Linksys hardware worked via reverse- engineering and some really neat modifications had started to come out. Enough that when the community demanded Linksys keep the old hardware available, they did... under a new model name ending in an L, for Linux. In the end, it didn't hurt them. They still got my $50 or whatever for this WRT54GS in the basement, but it's certainly no longer running their code! It does a hell of a lot more (but it's also too complex for Joe- sixpack to configure!) than Linksys ever intended, now that it has DD- WRT installed on the flash. Not that I use most of its new capabilities created by the Linux community -- I never thought I'd see a Linksys router capable of mounting a Windows fileshare via Samba as local disk space, but it'll do it. It is nice to be able to ssh to it, though, and get a BusyBox command prompt and fiddle with its guts.

I noticed some decay problems with an RLC-MOT we have on an SCom 7k. I've always attributed it to COS line propagation delay in the controller, but perhaps the 2.2 µF cap is the major culprit. We solved the problem by using the onboard audio gating, which I see uses pins 6 7 of the Micor squelch IC. Maybe we can ask Link-Comm to do a timing test on their unit and then change the 2.2 uF capacitor on pin 10 to something else and see if it changes the attack/decay of the COS action?

[Repeater-Builder] Link Communications Pre-Release Announcement
Link Communications introduces a new addition to its repeater controller family. The RLC Digital Controller (yet to be named) builds upon the proven RLC-3 and RLC-Club designs, while providing advanced features that aren't available in any other product. There are some things that we can already tell you about the design, some things that we haven't settled on yet, and some things we won't talk about until later :) We are looking for input to ensure that the new system includes the features that are most important to you, our customers. Among the features that we can talk about: The audio path will be digital (48K samples/second, better than CD quality). This will allow many features to be implemented without additional hardware (digital audio delay, voice recording/storage,squelch, etc) and without any loss of audio quality. Voice library can be easily updated or extended using standard .wav files. New Windows (tm) control software will make reconfiguring things on the fly simple, and will provide real-time status, indicating exactly what is going on at each moment. Improved firmware will retain the flexibility of the RLC-3 and RLC-Club series of controllers while making advanced features easier to use. Some of the improvements may also show up in a firmware update for those controllers. Modular design will allow easy expansion in increments of four ports (4, 8, 12...). Integrated Ethernet network interface will enable remote management (which can be done over the serial port as well), as well as VoIP/RoIP (Voice/Radio Over IP), over the Internet or a private network. Of course the controller will work without a network connection, but those features won't be available. Some of the features we could use feedback about include: A good name for the new controller. Type of front-panel display you prefer: LEDs for each signal (similar to current controllers), or an interactive LCD display? Remember that a computer running the new management software will provide real-time status too. Frequency-controllable remote base radios: What brand and model of remote base radio you are most likely to use (Icom IC-706, Yaesu FT-900, Kenwood TS-440...)? How many serial ports are needed? Typically each remote base radio needs a serial port for control. Is it worth adding dedicated 1/8 connectors for Icom CI-V radios such as the IC-706/7000, or is it better to just use pins on the DB-9 radio port connectors for the serial signals? Desired use for VoIP/RoIP features: Monitoring the repeater from a computer running the management software. Point to point links between radio sites (replacing RF links or linking sites that weren't close enough to link with RF). Interfacing to other VoIP/RoIP networks. If you would use this feature, which systems would you want to interface with (IRLP, Echolink, D-Star...)? These interfaces would probably be options. Number/type of I/O lines for site telemetry (remember that these require hardware and therefore affect production cost). Audio adjustments: Should the major transmitter and receiver level adjustments be made with physical pots or software-controlled pots? The advantage of physical pots is that you can just grab a screwdriver and adjust them without having to go though some kind of user interface (minor level tweaks would still be possible through software). The advantage of software-controlled pots is that you can make even major level adjustments remotely. If the physical pots were accessible without opening the case would it change your answer? Things we aren't talking about yet :) Subaudible tone (PL/DPL) Price Release date (stop and see us at the Dayton Hamvention for more, hint, hint...) If you have thoughts, ideas, questions, or want updated information, see http://digitalrlc.link-comm.com.
