Re: [Repeater-Builder]Transmitting interior temperature
I did a search for talking thermometer and came up with the following item for about 20 bucks: http://www.sightconnection.com/plu-477.html If your controller has outputs that you can control by touchtone you can wire the output to the pushbutton on the thermometer. Then couple the audio of the thermometer to the repeater transmitter. You can then query the repeater for temperature whenever you wanted. You would have to keep the repeater keyed up during the talking, possibly by a macro in the coontroller if it has that ability. This is an indoor-outdoor thermometer so you could read the temp both inside and outside the cabinet. If you lack outputs on your controller you could wire up a circuit to key up the repeater and send the temperature once an hour or so.

After moving things around in the cabinet last nite, and having the 1713 amp installed, I noticed an arcing noise from the amp. Keying the amp with the cover off revealed arcing at random places near the negative DC bus, and the 4.7uf capacitors getting very hot. Since this amp shows evidence of being serviced at some point, I decided to move back to the original 1703 amp. This amp is very clean inside and shows no evidence of ever being serviced. This amp too will arc with the capacitors getting very hot after only a few seconds of keydown. So what could be the problem. I am using a good wattmeter and load. Is there something in the antenna network after the amp that could be bad? I measured the SWR looking into the antenna network with the load on the other end and it shows 2.1:1. Isn't that a little high?? Or maybe the caps are simply old and dried out? Where do I look for the problem? Laryn K8TVZ Yahoo! Groups Links

RE: [Repeater-Builder]Transmitting interior temperature
Some outboard repeater controllers have an analog input made especially for an RTD (Resistance Temperature Detector) element. All you have to do is purchase the correct RTD sensor (a few bucks) and connect it to the controller with shielded twisted-pair cable. A few simple calibration steps, and you're done. Nothing could be simpler. The controller can be programmed to respond with a voice announcement of the temperature with a DTMF command, or you can program it to automatically broadcast a warning message if the temperature is not within the programmed setpoints. I believe that Link offers this feature on several models, and so does Pacific Research.

Re: [Repeater-Builder]Transmitting interior temperature
Another option to consider. KH2D has a program that rides along with Echolink. If you obtain a weather system that is compatable with ambient weather, it will read the information for you under this program, thus not needing to tie anything additional to the controller other than the echolink interface. The program is very nicely done, also can serve as an announcement system for simple repeater controllers.

RE: [Repeater-Builder] Celwave Preselector Tuning
There are 7 stubs, 4 are on the pass cans, 3 in-between the 4 resonators. Adjusting any of the 3 stubs (between each of the 4 resonators) has little effect on the skirt. The between adjust the size of the aperature (coupling) between filters. You won't find a whole lot of change in the passband response as you adjust them; that's just the way they are (or at least on the few dozen or so of those that I've tuned). --- Jeff
[Repeater-Builder] Re: Adding Remote Base to a Repeater
ldgelectronics [EMAIL PROTECTED] wrote: Yes, the tower spacing is vertical (not horizontal), yes the tx/rx on the repeater is 443.3 and 448.3 (5 MHz split) Don't get sideways over the vert/horz terms. We would be concerned with both the vertical and horizontal locations. Vertical distance is an easy best bang for the buck option. 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.

So I'm hoping to find someone that has been there, done that with some suggestions. The issue is that I want to add a same-band remote base to an existing repeater. The main problem is that the remote base is a transceiver and I can't find a way to provide proper isolation to/from the repeater. Here are the frequencies, but it looks like it really doesn't matter all that much. The repeater transmits on 443.300, receives on 443.800. We're using a typical UHF pass-reject duplexer with about 70 db of isolation between those two freqs. The remote base will transmit on 444.225 and receive on 449.225. I can put two antennas on the tower, but my horizontal space will be less than 20 feet. That's not going to help much unless you use a Yagi for the rmt. base antenna put the side null into the rptr. ant. You really need vertical isolation. If the remote base had a separate tx and rx, then a band pass can with a notch can (on the repeater freqs) on each side would probably work fine. Anyone have a good solution? A friend of mine actually brought the RX input of a Kenwood TM-241 out separately so it could be connected to a community RX antenna some 60 ft. away from the 2 meter repeater TX antennas. We were also able to add an isolator to the TX (to be a good neighbor) filters pads to the RX line until the IMD dropped to minimal levels. The 241 has rather poor dynamic range. Bob NO6B
