For those who have requested the link to Bob's article: www.repeater-builder.com/motorola/spectra/spectra-caps.html And, for those who expressed concern over the use of tantalum caps: I have also seen tantalums fail in a glorious manner. That said, the Spectra radios already contain dozens of tantalums, and these do not appear prone to failure. In retrospect, I think that the temperature rating on the Vishay capacitor I referenced (85C/185F) is too low for in-vehicle use. Certainly a 105C/221F cap would be a better choice.

But horizontal distance and location per side of a tower is also quite handy. Ok, now to fill in some of the blanks I left out. This is why the group is so coolÂ… things I thought were meaningless turned out to be important. The repeater power is 20 watts, the remote base is 10 watts. Relative to the grand scheme of things... your power output is not that big of a problem to work with. The repeater is an Exec II. The remote base is a Kenwood TK-805 (just because I have a stack of them). The broadness of the TK-805 is part of the problem and this could all go away by switching to another Exec II for the remote base. I've seen a lot of tk-805d radios used as links... and they are very popular animals. It would be worth your while to include some band pass selection (cavities typical) in series with the radio. For the splits, we have both (high TX and low TX) here in Maryland. The overall plan is to connect the new repeater with the remote base to an existing hub repeater on 449.225 TX and 444.225 RX. Clint Eastwood called it a cluster $%^ in one of his movies. Keep in mind the closest frequency spacing from any transmitter to any receiver is your largest gorilla in the room. Skipp, I like the additional notch in the repeater duplexer trick. That alone may do it. I do a lot of close spaced in-band commercial radio repeating and the notch in the reciver antenna path is da dope to take out the unwanted visitor. If this is a fixed frequency remote used only for repeater linking... then you should also include a notch or suck out cavity on the remote radio, tuned to the repeater transmitter frequency. We would assume the remote radio to be operated half duplex? I did the T-to-T thing with 2 and 4 band pass cans. The loss was in the 5-6 db range with 2 cans on each side. Not really worth it. If it were 2db per side, I would live with it. Something is wrong with your setup... you should be able to do better than the 5-6 dB loss value. Since your power levels are relatively modest (vs what they could be) you could actually replace the band-pass cavities dual port-hole with simple suck out notch cavities on the unwanted frequencies as long as things don't get too crazy with choices of frequencies, power level and a few other considerations. Thanks again for all of the input. Sometimes just talking it through helps a bunch. Dwayne Kincaid WD8OYG Just think of the gas money you'll save by not having to drive to the repeater site to disable a locked up link/remote base system. cheers, skipp Dwayne, I am not sure what the actual setup is that you are trying to co- locate on the same tower. Maybe you could re list the frequencies? Here are a few facts about isolation that may help: Vertical separation of antennas on 450 Mhz of 10 feet gives almost 50 db of isolation. 20 feet vertical separation gives around 60 db of isolation. The spacing is figured from center to center of each antenna. Horizontal separation of 10 feet on 450 Mhz gives about 30 db of isolation. Horizontal separation of 100 feet on 450 Mhz gives about 50 db of isolation. It is much easier to get more isolation with a notch cavity than it is with a pass cavity. Combining with cavities will usually require an isolator on each transmitter in addition to the cavities. A pass cavity or a low pass filter is always required after an isolator to reduce 2nd harmonics generated by the isolator. When adding a second station on a tower you need to figure the isolation between each stations tx and rx the same as if you were building a repeater. With separate antennas the antenna isolation gets you the biggest part of that isolation. On a multiple stations tower also don't ignore tx to tx isolation as you can have intermod problems if proper isolation is not provided. Keep in mind just because a transmitter is low power that most of the same problems still exist as with high power. A 10 watt transmitter is only 10 db difference from a 100 watt transmitter when figuring isolation required. 73 Gary K4FMX

[Repeater-Builder] Re: Stacked/multiple repeater controllers.
Hi Chris, Here's some things to think about. Most Commercial Repeater Tone Panels operate directly from the receiver descriminator output. They need to see the low frequency type signaling and the voice audio doing all the work for you inside their respective box. The typical output from a Commercial Repeater Tone Panel is a voice audio source and a second/separate ctcss/dcs source in most (not all) cases. Moving along to a typical Amateur Repeater Controller... Most repeater controllers prefer gated (on and off) voice audio with any signaling removed (that being ctcss pl or dcs). A large number of operators connect their controllers to ungated or constant audio so the controller input has noise on the input when no signal is present. Sometimes it's not a big deal but a lot of time using ungated audio adds a bit of squelch crash noise every time someone unkeys their radio. It just depends on how your controller is designed really. Some repeater controllers have input circuit mods so you can select unchanged receiver descriminator audio or flat audio that's been run through a de-emph circuit and possibly (or hopefully) a ctcss filter. Some newer microprocessor based controllers do like and use direct discriminator audio... doing all the repeater requirements including logic functions like cor for you. The typical or classic Amateur Radio Repeater Controller output is just the voice audio routed back to the transmitter. You could use your CSI-32 Tone panel for just the ctcss functions in parallel with a lot of Amateur Repeater Controllers for just the voice functions. The CSI-32 voice section would simply not be used. You'd still have to provide discriminator audio to the Tone Panel and voice audio (gated hopefully) and cos type logic to the common repeater controller. The Repeater Controller provides the return voice audio instead of the Tone Panel. The hook is to provide audio to both boxes at the same time and select the functions you want or need on the output side. Hope that helps... cheers, skipp I just acquired a Micor repeater with a CSI 32 Tone Panel, I am also almost done with the ICS Basic contoller that I am building from a kit.
