Re: [Repeater-Builder] Best way to adjust dev?
Youre confusing levels and deviation! I always strive for the deviation limiter at 5khz,use a 1khz tone at 3khz deviation in and out and CTCSS at .5khz out.They dont add up together like you think they would,so 3.6 is not what to shoot for,do them separately!You can get fancy and plot the response at 100hz increments all the way to 5khz to see any non-linearity in your audio path. The results may surprise you! DONT transmit into your service monitor's antenna port! I use a couple of rubber duckies on the monitor and dont connect it to anything. For folks who dont have duplex service monitors,take a handheld,send touch tone 5,measure what the deviation is,switch to the repeater output and adjust it to the same level. Good luck... - Original Message - From: Tim S. [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Tuesday, September 28, 2004 6:35 PM Subject: [Repeater-Builder] Best way to adjust dev? What's the best way to adjust the transmit deviation for a repeater. I was thinking of doing it this way. Setup the service monitor for duplex mode and hook the cable up to the antenna port on the duplexer. Manually key the transmitter and adjust the PL for .6 kHz deviation. Then adjust the generator for a 1k tone at kHz deviation with a PL tone at 6khz deviation. Then watching it on the duplex monitor adjust for 3.6 kHz (with .6 being the TX pl) on the transmitter. -Tim Yahoo! Groups Links Yahoo!

Re: [Repeater-Builder] Tower Painting and Lighting
Helipad = Heliport the last time I checked. In any case, I was not trying to cite all the cases why you may need to light a tower. I was pointing out that lighting is usually a legit alternative to painting.

Once the exact coordinates on the NAD83 datum, and the height of the tower in meters, have been determined to the accuracy required by the FAA, a request for an Aeronautical Study is filed with the FAA. The FAA will investigate the hazard to air navigation, if any, and will issue an order to the tower owner as to what lighting and/or painting- if any- is required. Don't forget that towers or buildings used to support antenna structures may need to be registered with the FCC as Antenna Structures. Regardless of the height of the tower, it may need to be registered with the FCC if the FAA determines that it is or may be a hazard to air navigation. I went through this whole process for a 404-foot tower on a military base, simply because my Amateur Radio Club falls under the FCC- but the military normally is beholden only to IRAC and NTIA. Judging by the multi-million-dollar fines being levied on cellular and broadcast companies who ignore tower lighting and painting rules, this is not an area where anyone should assume anything.

There are some that are both, but only because the owners decided it was better to light it and forget maintenance on the paint, so the paint is faded below standard. But, as long as it's lit, it doesn't matter. There certainly are cases where even below 200' the regulations apply. It's funny to see a power tower painted and lit while others on the same line, even higher in elevation, do not have to be. Same with water towers - the orange and white checkerboards are a hoot.

Standard ILS glideslope is 3 degrees, but they vary. That angle is from the ILS transmitter which is usually at or near the Runway Touch Down Zone and not at the runway threshold, but that varies also. 200' probably put your tower just inside the LOW side of the glideslope protection funnel (funnel would include the left/right indications of the ILS also of course). Venturing beyond the protection of the ILS low-side indications on an approach puts pilots beyond the point where they should only venture if they like hitting things. But there are crazy bastards who'll attempt to level off and fly back onto the glideslope from below out there... they all have death-wishes, or an innate inability to admit they screwed up and execute and immediate climb and missed-approach procedures. There are also so-called non-precision approaches which typically step the pilot down using the pressure altimeter and some non-precision directional information such as a Non-Directional Beacon (NDB) or GPS coordinates, etc... you usually end up somewhere between 200' and 500' AGL lollygagging around out near the approach end of the runway somewhere, looking ahead for any signs of something that looks like an airport. Non-precision approaches attempt to get the aircraft down to the final altitude 3-5 nautical miles from the runway environment to give the pilot of a 200 knot aircraft a little bit longer to look out the window for signs of an airport out there in the clouds... 4 miles isn't that far when you're doing 3 miles a minute! Even at a more common speed of 120 knots, that's still 2 nautical miles a minute. 5 nm out at 120 knots gives you 2.5 minutes to play Where's Waldo with the airport in a fog bank. Nautical miles are 6080' for those interested... so your 4 statute miles is less than that in terms of nautical miles, which is what pilots work in. 3.4 nautical miles to be exact. Most missed approach points for precision approaches like ILS are somewhere before the runway. Many non-precision approach missed approach points are in the center of the runway environment and many are based on speed and a stopwatch, if the navigation transmitter isn't on the airfield. And now I've bored you all to death with just the tip of the iceberg when it comes to instrument flying... and I've probably screwed some of it up, but it gives the flavor from the other side of the cockpit glass/plexiglass. To be fair to us radio folks, I've seen FAA drop non-precision approaches to an airport entirely after the construction of a tower nearby -- they sometimes determine the tower is more useful than the non-precision instrument approach. It's a tough juggling act they have. Keep those towers lit and painted!!! AND THANK YOU!!! We folks in our gas-powered flying bugsmashers appreciate it greatly when the WX goes down the tubes unexpectedly! (GRIN) Nate WY0X Yahoo!

RE: [Repeater-Builder] Tower Painting and Lighting
Hello, Did I mention this tower is going to be 4 miles due West of the South end of the runway, in other misspelled words, perpendicular to the runway. Thank God for spel chek! Paul -Original Message- From: mch [mailto:[EMAIL PROTECTED] Sent: Tuesday, September 28, 2004 9:05 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Tower Painting and Lighting Paul Finch wrote: 20 feet, seems kinda crazy to me but that's the Government for ya! Yep. They probably went by the slide slope (or whatever the other side of that is called - the rise slope?) and it came out to 190 feet at that distance. They also required that it have red lights at night as well as being painted! Being painted has nothing to do with the night lighting. It only pertains to daytime - paint or lit. There are some that are both, but only because the owners decided it was better to light it and forget maintenance on the paint, so the paint is faded below standard. But, as long as it's lit, it doesn't matter. There certainly are cases where even below 200' the regulations apply. It's funny to see a power tower painted and lit while others on the same line, even higher in elevation, do not have to be. Same with water towers - the orange and white checkerboards are a hoot.

RE: [Repeater-Builder] Best way to adjust dev?
Thanks Jim. Great explanation. -Tim -Original Message- From: Jim B. [mailto:[EMAIL PROTECTED] Leave the tone turned off first. If you have any way to put a local mic on the tx, or generate audio DIRECTLY into the mic input, set the deviation on the transmitter for maximum deviation, usually +/-5Khz (For ham rptrs, I set it up to abt 5.5 to keep folks from going into limiting normally. Ideally, a normal user with reasonable audio should not go into limiting very often.) Then go back and generate 1Khz @ +/-3Khz deviation, and set the repeat level for 3 in, 3 out.. It helps at this point to do a audio sweep and plot in/out deviation across the audio spectrum. Then, with no other mod, set the PL for +/-600-800 hz. -- Jim Barbour WD8CHL Yahoo!

Re: [Repeater-Builder] Best way to adjust dev?
Tim S. wrote: What's the best way to adjust the transmit deviation for a repeater. I was thinking of doing it this way. Setup the service monitor for duplex mode and hook the cable up to the antenna port on the duplexer. Manually key the transmitter and adjust the PL for .6 kHz deviation. Then adjust the generator for a 1k tone at kHz deviation with a PL tone at 6khz deviation. Then watching it on the duplex monitor adjust for 3.6 kHz (with .6 being the TX pl) on the transmitter. -Tim Leave the tone turned off first.
