[Repeater-Builder] RLC4, possible to make one port a priority over the others?
Howdy, Is it possible to configure a port to be a priority port over the other ports on the RLC4? So if for instance there is an active conversation occurring on port 1 but then someone keys up port 4, the audio from port 4 goes out the repeater while crow-barring the audio coming in on port 1. Is that possible? If so, how do I do it? 73's and thank you in advance, Mike KE6MRE

[Repeater-Builder] Re: Requesting SmarTrunk II Digital Controller Info
Smart-Trunk is/was in Southern California... their radio trunking format is different from all the other choices. But the format worked OK, was very low cost to buy the hardware and some radio mfgrs provided the format capacity in their lower cost radios... Kenwood being one. It was a very smart move and a decent choice if you knew what you were doing. But I was told the owner of the Smart-Trunk Format had a war with the Company (I'm sure it was probably over money) and reported to refus to allow the Company to continue to sell it, meaning the death knell for the format... sad. You might find someone who has the firmware for some of the Kenwood and Icom Portables and start a low cost trunking system. I picked a few controllers up off of Ebay last year (for almost nothing) with hopes of playing with them and the format... but haven't gotten anywhere with it yet. Doug posted a follow up with the manual url. The controllers will not work with CTCSS or DCS radio formats. cheers, skipp skipp025 at yahoo.om bbfmrf bbf...@... wrote: I have (3) ST-853 SmarTrunk II Digital Controllers.

Re: [Repeater-Builder] J-pole
A gain J-pole has extra element(s) separated by a phasing network. Google has several hits for Super J-Pole and perhaps the best I found is at: http://rbsfm.ej.am/joomla/index.php?option=com_contenttask=viewid=43Itemid=26 which goes into more detail. The design I used was publicized many years ago by a packet group out of the mid-west which used a 1/2 wave phasing coil separating the vertical elements. I liked this approach since it got rid of the unwieldy loop phasing network and thus allowed a fit inside the Stationmaster radome.

Re: [Repeater-Builder] OT: Tape
Rubber tape is good for high-vibration environments, where the insulation could get rubbed off over time. The rubber would get worn down before the insulation. Apply cloth tape over it to keep rubber from dripping off in high heat. Cloth tape is good for higher temps (won't stretch like plastic), and you can tie it in knots :) BUT, cloth tape attracts moisture! Cloth tape is good for base-ball bats! :) I like Super 88 and 33+, depending on the application. 77 is the cheaper stuff I use to tape wires together and pull through conduit. 73, KD6AAJ --- On Wed, 9/9/09, hitekgearhead hitekgearh...@hotmail.com wrote: From: hitekgearhead hitekgearh...@hotmail.com Subject: [Repeater-Builder] OT: Tape To: Repeater-Builder@yahoogroups.com Date: Wednesday, September 9, 2009, 3:47 PM I have heard you all mention scotch super 33 vinyl electrical tape and recommended it for a few different uses.

Re: [Repeater-Builder] OT: Tape
Actually, this is how I've been taught by several RF engineers to seal outdoor connections... a layer of Super 88, then linerless splicing tape (about 1/2~1 inch longer than the 88 layer), then a second layer of Super 88 (about 1~2 inches longer than the splicing tape layer). Seals up the connection well and allows for reasonably easy stripping of the seal in case you need to do work. -BR On Thu, Sep 10, 2009 at 11:53 AM, Jacob Suterjsu...@intrastar.net wrote: 3M Mastic tape?

Re: [Repeater-Builder] OT: Tape
If you can get a hold of the 'real' F-4 tape that the Air Force uses, it will not leave any type of mess behind and it is not affected by UV rays. I've seen stuff exposed to sunlight for years and it was fine. A sharp knife or razor blade applied longitudinally will split it open and allow you to peel it off completely, leaving no residue whatsoever. The only thing it sticks to is itself.

RE: [Repeater-Builder] OT: Tape
This is my preferred method as well for sealing connector splices. However, I do three layers each time (one layer up, down, up again of 88, then the same of splicing tape, then again of 88). Overlap each successive wrap about 50%. Always, always, always do the last wrap in each direction going UP. You want the open ends of the spiral wraps to be down so that water can't run in under the overlapping wraps. Although it seems obvious, I can't tell you how many hundreds of installations I've seen done bass-ackwards. For linerless splicing tape, I buy Scotch 130C or Plymouth L969. For bigger connectors (7/8+), use something wider than normal 3/4 tapes to help cover over the transition from the large cable's connector body down to the smaller connector. Scotch 88, 130C, et al are available in 1 and larger widths. Scotch 88T is Scotch 88 marketed toward the telephone industry and is often found in 1 and 1-1/2 widths. If you do prefer to use taffy (butyl tape), do the rest of the favor and first wrap the splice with a layer of 88 before applying the taffy.

Re: [Repeater-Builder] OT: Tape
Another trick I learned is to make 2 wraps with the adhesive in (on the work) then fold it over and make your wraps with the adhesive out as your first layer before putting the mastic/butyl tape down. This will keep the adhesive from getting all over the work, especially when wrapping coax connectors. Another suggestion is a squirt of silicone lube to keep the adhesive from sticking where you don't want it. I love the extra-wide 33+ tape. I keep a roll hidden in my toolbox for those 7/8 to N transitions... I also have a couple of cans of ScotchKote hidden from the CARB guys, who would confiscate it if they had a chance. That stuff is so full of VOCs it's illegal, but it's the absolute best thing as that last step in waterproofing a connection that's going to be hundreds of feet up on a tower. -- John Smokey Behr Gleichweit FF1/EMT, CCNA, MCSE IPN-CAL023 N6FOG UP Fresno Sub MP183.5 ECV1852 List Owner x10, Moderator x9 CalEMA 51-507 http://smokeybehr.blogspot.com http://www.myspace.com/smokeybehr - Original Message From: Jeff DePolo j...@broadsci.com To: Repeater-Builder@yahoogroups.com Sent: Thursday, September 10, 2009 12:52:39 PM Subject: RE: [Repeater-Builder] OT: Tape This is my preferred method as well for sealing connector splices.

I believe you stretch it a little when you're applying it, but once it's been applied, it is a completely single unit and cannot be unwrapped. (I tried.) The unofficial Air Force term for it is Queer Tape, Times Microwave

Re: [Repeater-Builder] Passive fer wifi
A pair of DBS dishes with a bi-quad antenna mounted in place of the feedhorn, fed by WRT-54G routers with DD-WRT firmware to tweak the power and turn off one antenna port will be perfect for this application. You can either flip the dish so the feed is on top, or mount the pole so it's horizontal (or at a 45* angle) to get the proper look angle for the dish. -- John Smokey Behr Gleichweit FF1/EMT, CCNA, MCSE IPN-CAL023 N6FOG UP Fresno Sub MP183.5 ECV1852 List Owner x10, Moderator x9 CalEMA 51-507 http://smokeybehr.blogspot.com http://www.myspace.com/smokeybehr - Original Message From: Kris Kirby k...@catonic.us To: Repeater-Builder@yahoogroups.com Sent: Wednesday, September 9, 2009 10:41:55 AM Subject: Re: [Repeater-Builder] Passive fer wifi On Wed, 9 Sep 2009, Jim Brown wrote: I have a buddy who has a son living about a quarter mile away, and he mounted a router in a weatherproof fiberglass box on top of his 50 ft tower, and his son gets a good signal. Getting the router antennas up in the clear was the answer for that system. Kinda like ATT did with those microwave towers on 4, 6, and 11GHz. 2.4GHz is very much line of sight stuff. I was always advised as a part of my training to confine the signal to as limited a space as I could afford to. From a network-sharing perspective, you'd be better off with a corner reflector at the top of the tower, or some form of narrow angle antenna, like a 15+ dBi dish. This confines the RF to an area around your buddy's son's house and at the same time looks like the access point is in his backyard. The advantage to this is that your router isn't off the air due to interference, and you don't have to worry about interlopers stealing your WiFi. -- Kris Kirby, KE4AHR Disinformation Analyst

RE: [Repeater-Builder] OT: Tape
In my previous post on this topic, I neglected to identify Linerless Splicing Tape as Scotch 130C. Here's more info on this great stuff: http://tinyurl.com/q6s9xz Scotch 130C and Super 88 tapes are available in several widths. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Eric Lemmon Sent: Wednesday, September 09, 2009 4:51 PM To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] OT: Tape Scotch Super 33 tape is great stuff, but Scotch Super 88 is even better- it's thicker, has a better adhesive, and it has better UV resistance. Cloth tape, AKA friction tape, should be pitched into a trash can. Scotch does make a Linerless Splicing Tape which is self-vulcanizing rubber, and is great for making a cable splice waterproof. You stretch it as you wind it onto the splice, and it sticks to itself. Cover that layer with Super 88 tape, and you never need to worry about water getting into that splice. If you can't find these tapes at Home Depot or similar home-improvement stores, try a commercial electrical supply house. If that's not convenient, go to 3M's online store and buy any Scotch product made. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com [mailto:Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com ] On Behalf Of hitekgearhead Sent: Wednesday, September 09, 2009 3:47 PM To: Repeater-Builder@yahoogroups.com mailto:Repeater-Builder%40yahoogroups.com Subject: [Repeater-Builder] OT: Tape I have heard you all mention scotch super 33 vinyl electrical tape and recommended it for a few different uses.

Speaking of tools, how about the specialized wrenches that can take the SMA connector nut loose on, oh, say, Yaesu VX 5 or FT-50's? Ray, KB0STN

[Repeater-Builder] Re: OT: Tape
I want to thank you all for you input, insight, and stories. You have confirmed exactly what I was thinking. I too have often experienced vinyl electrical tape getting gooey and sticky in high temp environments (automobiles). This is why I use heat shrink on most things. Also, I didn't think it would be a good sealer on coax connections just by itself. I guess everything has it's purpose. Now how about that waxed linen thread instead of zip ties
