Re: Re: [Repeater-Builder] 900 MHz MSF5000 up and running with CAT200 controller....
Well almost up! It is at my house in Murphy and will be over at the tower in a few weeks. I am going to run it across the IFR we have at the repeater building first before I hook it up to the antennas at the tower. I will play with it a few days at my house, but have no antenna other than a 3 dB omni which I got from TI. Since I do not have a tower at my house, the repeater just looks into a dummy load. I will haywire up the omni just to see what it sounds like with the two Spectras I have this weekend and then haul it over to the tower next weekend.

His instructions on the MSF page to modify the repeater for the CAT controller are very easy to follow and he is to be commended along with the rest of the repeater-builder hams whose info I have used successfully. Back late last year, I started this journey, not inexperienced in repeaters or this RF range (I am nearing retirement as a microwave engineer at Raytheon here in Dallas), but i knew absolutely nothing about rigs, repeaters, etc. on 900 MHz. I found this website and forum thru Yahoo and a few months later, here I am. Looking back over the journey, it was not hard at all, even for me. But Bob provided the gentle guidance and prodding to get me where I am today. Hopefully, the repeater will be up on the TI tower (antenna around 400 ft. high) in mid February. Look for the W5RD/R DPL 432 on 927.1125 MHz if you come thru town. The TI club also has repeaters on 145.43, 224.18 and 444.025 MHz on the same tower.

Re: [Repeater-Builder] Help CG Decoder Mastr ExecII
I am not familiar with your particular CG decoder, but I would guess that it is a phase lock loop type decoder, and you are adjusting the pot to set the center frequency of the PLL decoder. I have had best luck when adjusting this type decoder by having the normal discriminator noise at the input of the decoder and adjusting the loop frequency with a counter on the PLL test point. Fish around with a scope and find a place on the decoder that you can count, using a 10:1 probe to avoid loading the test point, and put the same 10:1 probe on your counter for the final count adjustment. I have a digital multimeter with an internal counter function that will count the low frequency just fine. When the adjustment is finished, input a signal generator with about 12 dB quieting and modulate it with your 103.5 tone at 500 Hz deviation and verify that the tone is detected. Then change the tone frequency to 100 Hz and verify that this tone is not detected, and likewise change to the 107.x tone and verify that it is not detected. If the tone above or below the correct frequency is detected, remove the input signal from the receiver and adjust the at-rest frequency up or down to favor the direction the detector needs to go. Then repeat the process to check for proper decode of only the desired frequency. A final test is to put the 103.5 tone back in the generator and add a 1 kHz tone at the same time and bring the total deviation up to 5 kHz and verify that the decoder is still working. If you have a level control between the decoder and the discriminator input you can jocky with the level to allow decode while the input deviation is varied over the range you expect to see. Sometimes a PL type decoder will drop out under voice peaks if the level to the decoder is set too high.

The customer is not going to notice a difference of say .150mS typical... especially when you/we/they have the typical go-head tone sequence distraction in their face for the time it takes the repeater to aquire. I swear LTR was much slower, just a little faster then DPL. More like 150 baud??? Anyway, right, for a typical commercial LMR customer, they aren't likely to be too upset at the difference, but public safety/first responders don't like the slow times of a normal CTCSS decoder :c/ It takes a long time for them to get used to any trunked system if they've been conventional. They also have a hard time with the delays involved with digital audio vs. analog... But what they do clearly notice is the nearly +6dB price of an Edacs radio vs an LTR format radio. Yeah...I think MPT radios typically run in between somewhere as I remember. You'll also find the older motorola formats, and others, that use a slow baud rate, will have longer channel grants. LTR is a VERY slow baud rate, but not as much data is sent, which partially makes up for it. Yep, again reference my above baud rate and data values. Everything is a trade. If we step back and look at the larger picture the question is if the various trades are worth the cost? Each person has to make his or her own choice. Indeed! Motorola formats used to be 3600 baud (or lower), where EDACS and P25 are 9600. I'm pretty sure MPT is 9600 as well. Jim Barbour WD8CHL Faster baud rate is nice but much of the private ltr LMR industry doesn't want to pay non generic price tag for equipment when the difference in channel aquire time is around 150mS. Not to mention you might get locked into only one brand/mfgr of equipment paying what they want you to pay. Well, that is *supposed* to be the idea behind both MPT and P-25...open architecture...but it'll take time for P-25 to come down in price. It's great these details get out into the public eye... information is the best resource. cheers, skipp Very definitely!!! -- Jim Barbour WD8CHL

A CTCSS board from a GE ExecII is NOT going to be tunable. I suspect there is one pot on it, and it will be an encode output level adjustment. There were a couple of different means of determining the tone frequency. The oldest may have a large mechanical reed that acts like a tuning fork. The most likely style will have a small white ceramic chip that has a tuned circuit in it. Either one will be labeled with the tone freq it's on, and if it's not what you want, it will need to be changed. There was also a crystal controlled unit that looks like a small round metal-cased IC. Again, it would need to be changed. There were also some newer ones that used a bank of dip switches. If you have one of those, consider yourself lucky! They are a bit more rare. For those, poke around maybe Repeater-builder, Doug Hall's GE reference page, or others and you'll probably find a chart to set the switches for the tone you want. -- Jim Barbour WD8CHL

RE: [Repeater-Builder] Re: Antenna on the side of a water tower
The water tank is a convex surface (at least on the side you can get to) not a concave surface. However offhand I don't think that you will be able to get far enough away from the surface of the tank to illuminate it properly and the curvature will most likely not be anywhere near optimum for the desired pattern. I would just mount the antenna on the rail and see what it does. As to a second antenna on the opposite side of the tank there is no need to have the two cables from the power splitter to be the same length. The two antennas are not going to see one another and they are not part of a phased array so cable lengths will be immaterial. There will be some nulls (and peaks) in directions where both antennas happen to be in view but moving a few feet one way or the other by the unit in view will change the phase relationship between the two antennas anyway. Nothing you can do about it.

Illumination of the (water tank as a) reflector (called a concave ellipsoidal surface) with a point source ( a yagi or other such similar directional type of antenna pointed at the reflector ) will yield a wide distribution of RF energy in the desired area of operation (close to 180 degrees) without the multi-lobes and nulls which can and do occur with the use of an omni-directional antenna regardless what ever the spacing from the antenna to the reflector (water tank surface). Since the reflector (water tank) is not a flat sheet, determination of the appropriate spacing from an omni-directional antenna to a spherical reflector is a compromise at best, if one hopes to achieve an optimum radiation pattern in the area of desired operation with-out undesirable nulls. One thing is for sure, you cannot expect more than 180 degrees of operation from the side of the water tank on which the antenna is mounted. Any signal found on the opposite side of the tank is the result of multi-path reflections, and will not and can not be dependable or predictable for use. You may want to mount another directional antenna on the opposite side of the tank to improve the coverage in the opposite area. This obviously would require a splitter ( power divider) to couple the two antennas and /or an additional length of transmission line from the xmtr to the 2nd antenna. Both lines feeding the antennas from the power splitter should be of the same length. And there may be nulls at the 90 degree and 270 degree locations around the tank with two antennas mounted at 0 and 180 degrees. Good Luck! 73, Allan Crites, WA9ZZU Jim B.

I've also worked with quite a bit of LTR stuff, although not for the past 13 years or so. It was always very solid and reliable; the only weak point that I recall was that if you lost a PA on one of the channels, radios homed on that channel would be kind of stuck in limbo. This didn't happen very often, but it did happen. The other thing (that's already been mentioned) is that people have to be trained to pause between the time that they keyed the mic and the time that they began speaking. Even though the delay is only a fraction of a second, it is significant to folks used to conventional radios and they'll need to be aware of. Not a big deal, just a training issue.

Kevin Custer Nice article, and I agree that getting the right capacitor value with the crystal is important since that keeps the crystal in the center of the curve in the standard GE chart shown in every discussion about ICOM's in their manuals. But I have a question... or maybe it's a comment... and this might be a long one... It's about the article's references to 5 PPM... and the dangers of using a 5PPM device in a UHF repeater. THERE ARE NO 5 PPM ICOMs when they're operated in the center of their temperature range! All 5C ICOMs (and even EC ICOMs!) are TWO PPM (2 PPM) devices inside the CENTER of their temperature range!! That's not mentioned anywhere in the article, and the article seems to try to scare people into using only 2C ICOM's on UHF! That's not correct... read on... In the MASTR II manuals, it's apparent from the text that the high and low side temperature compensation of a 2C or 5C doesn't even kick in, until some awfully wild temperature extremes are breached. Here are some of the text items in the LBI to back up this statement: (from http://www.repeater-builder.com/ge/lbi-library/lbi-4561c.pdf) Should the 5C-ICOM compensator fail in the open mode, the EC-ICOMs will still maintain 2 PPM frequency stability from 0C to 55C (+32F to +131F) due to the regulated compensation voltage (+5 volts) from the +10-Volt regulator IC. At temperatures above and below the midrange additional compensation must be introduced. The cold-end compensation circuit does not operate at temperatures above 0C. When the temperature drops to 0C, the circuit is activated. The hot-end compensation circuit does not operate at temperatures below +55C. When the temperature rises above +55C, the circuit is activated. And of course, the kicker... Service Note: Proper ICOM operation is dependent on the closely-controlled input voltages from the 10-Volt regulator. Should all of the ICOMs shift off-frequency, check the 10-Volt regulator module. Setting 10V *exactly* in your MASTR II's is important for frequency accuracy. It's rarely mentioned anywhere in articles, but it is carefully mentioned numerous times in the GE manuals themselves. Set those 10-Volt regulators accurately, folks. It's clear from the GE chart and description (and even the schematic that shows the high and low side compensation circuits with SWITCHES that turn them on and off!) that what compensates the crystal in the mid-range temperature area is NOT the high and low side temperature compensation circuits found in the 2C and 5C ICOMs... at all. It's the CAPACITOR that was chosen by the folks compensating the ICOM! So, in that sense your article is very VERY accurate. You should always choose to pay ICM or someone else to compensate your ICOMs if you have any desire to make sure they're dead-nuts on frequency and going to stay there. ANY ICOM compensated properly will exhibit 2 PPM accuracy in the middle temperature range of 0C to +55C (assuming you're feeding the EC ICOM with +5V on the COMP line, if you just *have* to use one of those). If your radio lives in a temperature controlled environment, the use of 2C over 5C makes NO difference at all, and you HAVE a 2 PPM accuracy with either one. In fact, if a constant +5V is placed on the compensation line, the EC's will also do this. For a backyard repeater living in someone's basement, the 2 PPM provided by a 5C is the same 2 PPM accuracy provided by a 2C. There's no difference at all as long as you're in the middle temperature range. The text of the article would indicate that there's some grave danger when using a 5 PPM device on UHF, but a 5C ICOM is a *2 PPM device* between 0C and +55C! If your system is staying between 0C and +55C, using a 5C will exhibit *2 PPM* stability according to the GE manuals. In fact, even a properly fed (solid +5V on the compensation line) EC ICOM will do that, too. They maintain 2 PPM accuracy IN THE MIDRANGE TEMPERATURES by the choice of capacitor by the crystal house when they compensate the ICOM. And that was the REAL point of your article, I think... and I agree... as does GE. If the capacitor in the ICOM was chosen to match the crystal... then things are good. But the text in the article about the difference between 2 PPM and 5 PPM makes people think the ICOM's labled 2C and 5C are only 2PPM and 5PPM accuracy. This is NOT true, and people shouldn't be afraid to use a 5C ICOM on a UHF repeater *in a temperature controlled environment*. The only time the
