[Repeater-Builder] UHF Distance with 20 watts to Mobile, How Far
Keep the roar down, but am trying to figure what one would expect the distance of a 440 repeater to be with 20 watts out, into a Diamond Antenna up 50' fed by 7/8 hardline, 6 DBi of gain. The user on the other end is using a base antenna, not sure of type, but about 50' and cannot hear the repeater. In my mobile I can hear it for about 10 miles and then it's super noisy then gone. Any way yo figure what one should have expected? Mathew Yahoo!

[Repeater-Builder] Touch lamps
Yea, I know it is a little off topic for this group. But this is one of the most technically competant groups around! Has anyone here had any success stories in dealing the the RF noise received from RFI given to Touchlamps?? I have a problem where every time I get on 75 meters/40 meters/15 meters (with 100 watts off my balanced fed dipole), I make the neighbor's touch-lamp lights go off/on/bright/dim with my modulation. Also, the lights put out RF trash starting at 210 Kc every 210 Kc all the way up to 12 meters!!! right now my plan is to build a low pass filter to let the 210 Kc signal for the touch-lamp pass but filter out all above 210 Kc.

Re: [Repeater-Builder] UHF Distance with 20 watts to Mobile, How Far
Thanks for the input here. I thought something was a bit strange for the distance. I'm thinking in the duplexer, but am going to have to hook the transmitter up and have someone a distance from the repeater hear the signal, almost bet it is there. As far as I can tell, the recieve side of the repeater is working ok. Just no distance on the transmit. Keeps me moving. Mathew A simplied formula for use when both antennas (I know, antennae) are the same height, assuming a smooth earth's surface and assuming an earth's radius of 4000 miles, which is close when we take into consideration the RF bending effect at UHF, would be: 2.4 times the square root of the antenna height (using the height of only one of the two antennas). Thus, you should expect an approximate distance coverage of: 2.4 * 7.071 = 16.97 miles without obstructions. Maybe others have a better, more accurate or easier method of obtaining the answer??

Find a small screw that will go in its place. Then screw a barrel connector in the side of the T connector. This should isolate the side connector from the two end connectors. You may want to put a couple of layers of tape over the screw head to make sure there is not a direct connection between it and the barrel connector center. If you have too much signal you can leave the screw out of the T connector. __ Do you Yahoo!? Take Yahoo! Mail with you! Get it on your mobile phone. http://mobile.yahoo.com/maildemo Yahoo!

Re: [Repeater-Builder] Mastr II question
I have converted a few to 6 meters,the transmitters were no problem.However,I had to mod the helicals in two of them to get acceptable sensitivity at 52mhz. This involved removing the first two helical coils and shorting two turns at the top. You will need heavy duty soldering heat! As far as the base station power amps go,if it has the full continuous duty heatsink it will run at near rated power without much problem. I would use a fan for repeater duty,my vhf has been running 100 watts for 27 years without a single problem! Good luck! Doug Bade wrote: The main problem to watch for is heat/swr issues on the PA as it is potentially going to cook itself at full rated power with a high duty cycle... It will make full power and full sensitivity in 52/53 mhz, but I would de-rate the PA by a bit to protect it if it is going to be on a lot. I have not seen one which did not tune up on 6m just fine.. and I know of at least one which left the factory in the late 70's tuned on 6m... 52.525 as I recall on channel 2 repeater splits in others...

Re: [Repeater-Builder] Amateur P25 repeater on the air
If P-25 is an open standard, then why would you need analog ID's?? AX-25 (Packet) does not use analog ID's. James Nate Duehr wrote: Jim B. wrote: By way of PWF: http://www.k6ccc.org/k6ccc-r.html Neat Jim. I've been playing around with P-25 via a borrowed radio. Very interesting stuff. On this repeater: http://www.rmrl.org/rmrl_news/rmrl_goes_digital.htm Your web page mentioned "still debating about analog ID's"? Why? Your web page also doesn't mention if your users are typically monitoring a particular talk group? The group above uses $. Locally here anyway, we're ID'ing in digital, can't see any reason to change emission type to ID -- if someone were monitoring, they'd have to change receiver types too, which seems counter-productive. P-25 is an open standard, anyone that needs to copy the ID certainly can. (i.e. FCC) Hams can't run with the encryption features enabled, either, of course. The repeater also ID's via MCW over the digital channel when someone's using it in digital mode, which sounds really odd, but is copyable. (GRIN) Kinda like a CW operator with a generator that can't quite keep up with his amp. Heh. The repeater above turns off CTCSS when transmitting in digital mode, but some local users still run without CTCSS decode on analog, so there have been some questions once in a while about "what's that horrible white noise blasting the repeater at 45 minutes after the hour?!". Heh heh. Yes Virginia, that would be the digital ID going by... The most interesting aspect of digital so far is of course that "static" simply doesn't exist. Instead your ear becomes tuned to what the vocoder does when it's erroring... Sometimes the "Max Headroom" effect... repeated syllables. Sometimes the audio gets "raspy" as the vocoder struggles to replace lost bits. But no "noise" per-se. You can get pretty good at it and tell when someone's starting to get marginal, from my limited playing with it, if you know they're headed out of range of the system. If you DON'T know they're headed into a dead spot they'll just be gone... bye... heh. On the flip side, the S/N gains of digital are real -- places where the system is 50-60% or more white noise, the digital sounds fine with a few digital "artifacts". In my office at work where I'm surrounded by PC's that throw RF hash, analog copy on just about any local repeater is horrible... the digital systems sound perfect. Interesting stuff. Still expensive but coming down in price rapidly. Rumor is that Motorola will be to the $400 price range on the HT's by next year-end perhaps? We'll see. The closed IMBE CODEC in P-25 is the hobbling issue for REAL experimentation, unfortunately. There *ARE* smart enough people in the ham community to hack on DSP code these days -- but it'd be worthless without the source for the CODEC. Mm... Digital Toys! Nate WY0X Yahoo!

Re: [Repeater-Builder] fiplex duplexers
Hey Jed, I bought one about a year ago for a brief case repeater and it seems to work OK. Maggiore is selling them and Paul says they work OK. I did not buy the one I have from them I got it from EBCOM. All of the duplexers we have been buying for the system up-grades have been TX/RX with the Cook Tower mod. We have been very happy with the new TX/RX at the up-graded sites.

RE: [Repeater-Builder] Touch lamps
Title: RE: [Repeater-Builder] Touch lamps I have always had great luck in eliminating the RFI element (turning them on and off from your RF) of touch lamps by installing 2.5 mH chokes in the touch sense lead of the lamp. Install the chokes as close as you can to the PC board or electronic module. The choke can be rated as low as possible on it's current capacity. J.W. Miller has some very small 2.5 mH chokes. Ron WW8RR -Original Message- From: JOHN MACKEY [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 22, 2004 10:11 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Touch lamps Yea, I know it is a little off topic for this group. But this is one of the most technically competant groups around! Has anyone here had any success stories in dealing the the RF noise received from RFI given to Touchlamps?? I have a problem where every time I get on 75 meters/40 meters/15 meters (with 100 watts off my balanced fed dipole), I make the neighbor's touch-lamp lights go off/on/bright/dim with my modulation. Also, the lights put out RF trash starting at 210 Kc every 210 Kc all the way up to 12 meters!!! right now my plan is to build a low pass filter to let the 210 Kc signal for the touch-lamp pass but filter out all above 210 Kc. I got plans for this from QST April 1995 pages 72-73. Yahoo!

Jed; There are several models which can do this... Motorola Spectra 900 for one, GE TMX9315, Motorola Maxtrac 900 with help... GE MDX 900 mhz with some additional hardware. The Spectra is probably the easiest of the lot... Some Kenwood 900's can do too, as well as Motorola GTX.. ALL need mods to some degree, some more, some less .

adam you takes the t- connector and grabbing the center pin with a needlenoe pliers unscrew the thing. then cut off the part that sticks out and file the shoulder flat. this will give you an air gap. then reassmeble the connector having been careful NOT to lose the parts.(sometimes very difficult) and tighten the now shorter pin snugly or is it snuggllyy...whateverthen cut a small piece of poly ethical or styrofome...or is it foam...any how...stuph the plastic insulator into the connector and screw a uhf bullet into it. violaiso-tee...isolation kinda random but isolation is what you want. total time for assembly for a normal person probly 15-20 minutes. took me 2 hours i lost parts in the carpet. happy holidays mdm ted copyright 2004 k9mdm all rights reversedunless you don't tell me then who cares.

Re: [Repeater-Builder] Did measurement of inductors change???
Yea, the difference between uH (Micro-henries) mH (mil-henries) is what I've always understood since my earliest training. But the fact that I have been unable to fine mH chokes only found uH chokes made me wonder if the measurement system of inductors had changed!! (sort of like when capacitor measurements changed from uuF to pF) I was doing this search late last night. Today, a little more fresh, I'll go back to work look at the Newark Allied catalogs again!
