[Repeater-Builder] Re: RadioShack Recalls Power Supplies Due toElectrocution and Fire Hazards
It's funny that you should mention that... I am the Chief Engineer for 2 television stations where I live. One of my transmitters is out of state in Arkansas. I too built two identical buildings for my full power ATSC transmitters. The building out of state was such a breeze!!!.. Because the square footage was less than X.. I didn't require any inspections, or strange permits The state feller showed up, looked up at the tower, had a cup of coffee, and asked questions not related to building, (hunting accually) and left. HOWEVER.. IN Louisiana... First I couldn't act as the General Contractor.. Then you have 2 different inspecting officials, Fire Marshall, and Local building inspector (which was sub contracted out to another company) It was a living nightmare... When I started, I had to submit plans and drawings of this little 20x40' building. Then they wanted exact drawings of the electrical and plumbing for the building. Well, if any of you have installed a Television transmitter lately, A lot of it is quite dynamic depending on location of the tower to the ice bridge, feed through points, and the location of the RF system. It took a month and a half just to get the plans approved through the fire marshall... The rest is just down hill, including handicap accessable bathroom (uh..hello, you have to walk quite a bit to get to the building. I'm afraid a hover-round isn't gonna make it.And this is NO offence to our disabled repeater builders)emergency lighting (the site has a huge backup generator that kicks on after 2 seconds of power failure), emergency egress signage (there are no walls except the exterior walls, and one door) When it came to fire suspression systems, they couldn't figure out why I didn't want to use sprinklers. A non conductive, non residue hand held fire suspression system finally was agreed upon. My project in Louisiana cost double of my other one. In short... Building codes are NOT the same from state to state. Never assume that because it NEC compliant, that it will pass Louisiana's (or another state's) code.. 73 de Joe KB5VJY --- In Repeater-Builder@yahoogroups.com, Christopher Zeman [EMAIL PROTECTED] wrote: It's funny you mention building construction.

Re: [Repeater-Builder] Re: RadioShack Recalls Power Supplies
Bruce,
Probably should kill this topic for it has radiacally changed from orginal
posting and not really repeater related although AC power is a concern for
about any repeater builder.
I think one reason for separate wiring to each outlet is the way so many are
wired using the little spring loaded connections that require only stripping
the wire and inserting...do not use the screw terminals that most all have.
Over time the spring tention weakens producing a poor connection at one outlet
that can lead to a high resistance and heat. Having multiple outlets on one
string of wiring can amplify this situation.
I don't like the strip and insert connections and think they sould no be
allowed. Whenever I replace/repair an outlet I cut the wire and connect to the
screws.
I am sure there are other reasons for separate wiring to each outlet. The
electric code has many not so obvious reasons for what they do mainly from
experience.

I figured that was A local code, not NEC. The only reason I can think of for
that requirement is the ampacity of the 12 or 14 ga wires. While we all know,
in actual use, 2 or more outlets strung along will not all have 15 amp or
higher loads in EACH outlet. However, theoretically, each outlet could have A
20 amp load plugged into it.That is probably why some pencil pusher decided
each outlet needs its own wire. (Never mind the fact the breaker would trip
regardless of what is plugged into each outlet or the number of wires leading
to said outlets, but that's another crazy thread) As for the Breaker Box, I
would assume each also has its own breaker. Trying to stuff more than one wire
into A breaker would more fun than I care to have. BruceKE5TPN
Dave,
This is a code requirement here in my county and think all of Florida.
The code requirements for building is a county/state issue and vary. Most use
the NEC code. Many have additional codes such as having wind resistance
building. The way homes are constructed in the north would not be allowed in
Florida mainly due to the wind. This is why we see so much concrete block
construction with lots of requirements for attaching to foundation and roof

Re: Re: [Repeater-Builder] Re: RadioShack Recalls Power Supplies
Gary, I got this info from a local licensed electrican who does a lot of home construction. He was not happy either. My wife owning a hair salon also has seen a number of required changes in your shop. I do not thing there is a breaker for each outlet, but more than one outlet wired to multiple outlets to a single breaker. I had wondered about this since I spoke with the electrician. There are lots of building requirements for homes now in our area that are not standard in most of the US. We have to use concrete block construction, in the past of over 10 years ago one simple layed the blocks. Now in all blocks vertical channels a steel rod must be inserted and connected to the foundation and the hole filled with concrete. A few years ago only a few of these were required, but now all on the outer wall must be. Since huricane Andrew where they found many stick/2x4 built homes that got so easily blown away and the other hurricanes in recent years many building changes have been mandated. Many problems occured due to electical problems causing fires and other hazards and many changes have been made. My home built in 1988 would not even come close to code today. We now cannot use 14-2 w/g wire. It is 14-3 or larger. All breaker boxes must be assible from the outside. Had a friend who was updating his box and found it had to go outside. Definitly increased the cost. There are many many codes not national that must be followed. And for good reason. Would not expect to have all to have to build for high wind in say Chicago. They don't get too many hurricanes up theres. They do get tornados, hi. 73, ron, n9ee/r From: Gary Glaenzer [EMAIL PROTECTED] Date: 2008/07/07 Mon AM 08:36:19 EDT To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Re: RadioShack Recalls Power Supplies Ron; That requirement (if it is correct) is NOT part of the NEC It would be a local thing, and quite frankly, I feel the original poster of that info may have incorrect information It would, among other things, limit a home to (42 - circuits used for other than outlets) receptacles, there being only 42 circuit breaker spaces in a 200-amp panel Gary - Original Message - From: Ron Wright To: Repeater-Builder@yahoogroups.com Sent: Monday, July 07, 2008 7:15 AM Subject: Re: [Repeater-Builder] Re: RadioShack Recalls Power Supplies I am sure there are other reasons for separate wiring to each outlet.

I'll have to run my 900 MHz radio up and see what's there. I suppose this is one more reason why those who know just jumper the MIC jack pins 3+4; it works on ALL radios, regardless of race, creed, color, sexual preference, or political affiliation.

To: Repeater-Builder@yahoogroups.com Date: Monday, July 7, 2008, 11:30 AM Hi Bob, Well an interesting thing happens when I try two different band Maxtrac Radios. The Off-Hook option appears in the Radio Wide Settings Table as you suggested, but only for the low UHF and VHF band radios. When I use the same software to read a Conventional 900 Radio the Off-Hook option goes away and all I see is the Handset Y/N option left behind. I know the Conventional Firmware for the 900 Maxtrac radio is different from the lower frequency bands... but the off-hook option would normally be expected to be available in both bands. I guess I'm going to make up more Radius Repeater monitor mute plugs. Thanks for taking the time to reply cheers, skipp Bob M. msf5kguru@ wrote: Yes. Check the Radio-Wide settings page, left column, bottom. There should be something regarding the hang-up box (HUB). TAB to that field, press F1, read the HELP screen about it, and make the appropriate choice. Most people just short out pins 3+4 on the back of the MIC jack inside the control head. You can still unsquelch the radio by using the MON button on the front. Bob M.
