[Repeater-Builder] Motorola GM300 vs SM120??
I am running a UHF repeater using two Motorola GM300s and a RICK. Would it be worthwhile changing to two Motorola SM120s? We operate it at a broadcast site with lots of high RF fields. Is there a concensus on which repeater, commercial or amateur has the best receiver? Sincerely, Michael Bloom W7RAT
[Repeater-Builder] VXR-7000 Rear ACC Jack and Remote Function
I am trying to connect an RC-100 controller to the rear jack of my VXR- 7000. For some reason, when the remote switch is pressed and the LED is on, the repeater ignores the ACC jack and still acts the same as when the repeater is in local. Any ideas? I didn't program the repeater, but I have the software. Can you disable the remote mode in the software? HELP! Thanks in advance, Jerry K8CMI
Re: [Repeater-Builder] rf power modules
Seems RF components are high in price compared to the rest of the electronic world. I have found RF Parts to have competive pricing and often much better than over the counter local pricing. RF Parts is one source for the typical Ham and do recommend them. This of course when wanting 1 or 2 components. Now if you want 100s that is another issue. 73, ron, n9ee/r From: JQ [EMAIL PROTECTED] Date: 2008/07/05 Sat AM 10:03:34 EDT To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] rf power modules I am in need of a M67746 power module. anyone know of suppliers to check with.

Re: [Repeater-Builder] china made radios
I also purchased 2 of the HTs, one for VHF and one for UHF. I chose the FDC units at $59.50 shipping included although there are others. The VHF covers 130-174 xmt and rcv. The UHF covers 400-474 xmt and rcv. Both are keyboard programmable, have 99 memories and come with a desk top charger that can charge battery attached or detached from the HT and runs on 110-240 VAC. A spare batter is $11.50. They have CTCSS and DCS and except for not having a DTMF pad they have lots of usable features. They will also do repeater offset programmable up to 10 MHz. I am not sure if they will do 12.5 or 6.25 kHz tuning. The manual, same for VHF and UHF, is in English and think Japanese and is about 15 pages each. The manual explains little about what does what, only how to setup to do whatever. Tells you how to prog CTCSS tone, but has little info on what CTCSS is. Same with rest of features. One can see these HTs at www.radiogearpro.com. The cost includes shipping. I use these on the Ham Bands, but another reason was for ARES/RACES/ACS operation. In a disaster one will need to talk with other agencies, even the power company. These can be setup in the field for this. As Hams we can operate these rigs. However, they are not type accepted for the US and think use in commercial can be a problem even GMRS or MURS. The largest market for these rigs are the mom and pop businesses needing some sort of HT comm. I am not sure what customs would do with these if they knew of the non-type acceptance. Might be a problem, but mine came thru with no problem. Takes about 10 days for coming from far east, think China or Tiwan. 73, ron, n9ee/r From: safemale1 [EMAIL PROTECTED] Date: 2008/07/06 Sun AM 03:39:33 EDT To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] china made radios i have a ht that was made in china and sold in tiwone spelling? it was/is 60 shiped 136-174 mhz 5 watt the worst part in the man. butt for the price i love it lots more radio for the buck 1/2 the price of a yasue sorry for the offtopic i will shut my mouth At 08:15 PM 7/5/2008, you wrote: Ron Wright, N9EE 727-376-6575 MICRO COMPUTER CONCEPTS Owner 146.64 repeater Tampa Bay, FL No tone, all are welcome.
Re: Re: Re: [Repeater-Buil der] Re: RadioShack Recalls Power Supplies Due toEle ctrocution and Fire Hazards
Gary,
I've noticed in panels the safety ground and neutral go to a different buss
bar. I had thought maybe because the neutral was sometimes, not now to code,
smaller than the neutral. However, both got connected to the panel case. One
can Ohm out neutral to safety and only see the resistance in the wiring to/from
the panel. However, as you well know, should not be considered the same.
In most plastic coated wireing I see today the safety wire is green coated, but
some is still bare as you said. I've seen lots of this.
Now in our county following NEC code the safety wire has to be same size as
neutral . No more of the 14-2 w/G cable, but 14-3 one being safety ground color
or bare. Also they are doing something different, a separate set of wires
must be ran between panel and each outlet...no more of one wire to one outlet
and then from here to another outlet, etc. Can you imagine the extra cost and
labor. Not sure what they do at the breaker panel...put in separate breaker
for each outlet. Not sure if this NEC code or something to do with the
hurricane code we have here in Florida. We do lots of construction very
different here, hi.

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.

Re: Re: [Repeater-Builder ] Re: RadioShack Recalls P ower Supplies Due toElec trocution and Fire Hazards
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
securing. Just different part of the US.
Same with electric code. For various reasons some additional changes are often
made. Just because you have a code in your area does not mean it is in all of

building codes until the 70s. Can you believe this.

It's funny you mention building construction. I work for a company that,
under the original ownership in the 70's, built two identical
facilities, one in California and one in Illinois. I work for the
company in Illinois. The buildings were constructed to California code,
and I'm sure you can imagine the problems we've had with the buildings

1. If the transmit frequency is also off by 4 kHz, then you should adjust the 14.4 MHz oscillator via the hole in the front or top of the RF tray. 2.

[Repeater-Builder] Re: RadioShack Recalls Power Supplies
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.

wires must be ran between panel and each outlet...no more of one wire to one
outlet and then from here to another outlet, etc. Can you imagine the extra
cost and labor. Not sure what they do at the breaker panel...put in separate
breaker for each outlet. Not sure if this NEC code or something to do with
the hurricane code we have here in Florida. We do lots of construction very
different here, hi.

I don't know what part of the US you live in, but around here (western IL)
the grounding conductor ('safety ground') is bare in Romex-type cable, and
may or may not be insulated in conduit, and usually one size smaller than
the 'main' conductors.
Also, the GC goes to one bus-bar, the neutral to another, the GC bus-bar is
bonded ot the neutral at the SERVICE panel (incoming power, the one with the
'Main' braker that shuts off all power), but is kept separate in all
sub-panels, and from the sub-panel(s) there must be a separate GC (coded
green) run back to the GC bus-bar in the service panel.

[Repeater-Builder] RadioShack Recalls Power Supplies
Sometimes even hiring a licensed contractor is a bust. We moved in to a
new place out in the country a few years back and I decided to have a licensed
electrical contractor install an outside 110V socket for keep the RV batteries
charged,
etc. At the same time I had him pre-wire a GFI/220 circuit for the new hot tub
I ordered.
To make a long ugly story short -- instead of a 110 RV outlet I got 220 --
which
really lit things up in the coach the first time I plugged that in. Chargers,
inverters,
sat receiver, DV Player, all kinds of stuff I'm still finding.
I don't ever get into the hot tub without remembering the RV outlet disaster --
but so far nobody's been fried.
Trust but verify...

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.

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 securing. Just different part of the US.
Same with electric code.
For various reasons some additional changes are often made. Just because you
have a code in your area does not mean it is in all of US. It is county mostly
with some state codes. In my county there were NO building codes until the 70s.
Can you believe this.

Where is the requirement for running a
separate feed to EACH OUTLET
REQUIRED? Not in the US A dedicated
out is required for certain
special situations but not for each outlet
elsewhere. There are certain
other requirements such as GFCI and AFCI.
But, certainly no dedicated
feeder for each out.

Gary,
I've noticed in panels
the safety ground and neutral go to a different buss bar. I had thought maybe
because the neutral was sometimes, not now to code, smaller than the neutral.
However, both got connected to the panel case. One can Ohm out neutral to
safety
and only see the resistance in the wiring to/from the panel. However, as you
well know, should not be considered the same.
In most
plastic coated wireing I see today the safety wire is green coated, but some is
still bare as you said. I've seen lots of this.
Now in
our county following NEC code the safety wire has to be same size as neutral .
No more of the 14-2 w/G cable, but 14-3 one being safety ground color or bare.

Not

[Repeater-Builder] High AC Line
Apologize for being off topic but a safety question. Do you people monitor your AC line at your home, business,shop etc? I've been having a problem in central NJ with high line around 1:00 am. Our spec is 115.2 - 124.8. Around 1 AM I run 127.0, 126.4 with a daily average around 124 during the rest of the day. As we all know many electronic products are really not off when we hit the off button. Although today's electronics are designed for higher AC line voltages. I've already experienced one work bench light ballast fire. Plus a large number of smoked electronic test equipment. I continually see phase shift capacitors being switched in and out on my line monitor or is it bad grounds? The volt readings are done with a Fluke 77 that has been calibration checked and certified correct. Would someone educate me on proper power utilities. Please contact me off R-B unless others feel they would like to know also. Again I apologize burning up air time. Gary K2UQ [EMAIL PROTECTED] (mailto:[EMAIL PROTECTED]) **Gas prices getting you down?

RE: [Repeater-Builder] High AC Line
Gary, There are two primary causes for abrupt changes in line voltage: Substation tap changers and capacitor switching. The national nominal voltage in the United States is 120 plus or minus five percent. Electrical utilities go to great lengths to regulate distribution voltages, which usually range from 4,160 volts to 22,000 volts. You often hear old-timers talk about 110 or 220 volts, but those have not been available for about 50 years- except perhaps in some isolated areas with local power generation. The substation transformers have LTCs (Load Tap Changers) which can adjust the distribution voltage in small steps, usually 1.25% or 2.5%. The problem with this voltage regulation method is that power users close to the substation will see a higher voltage than distant users. A well-planned distribution network will have additional regulating transformers out in the field to more closely keep the user voltages at 120/240 VAC in single-phase systems, or at 120/208 VAC in three-phase systems. Industrial users will probably be metered at 277/480 VAC. Since distribution systems are primarily inductive, capacitor banks are used to increase the power factor and raise the voltage on long feeders. These capacitors may operate automatically, but are commonly switched in and out on a time schedule. If you put a voltage logger on your home power system and see a jump of several volts at the same time every day, that is almost certainly a capacitor bank. A case in point: Several years ago, I measured a jump of my line voltage from 119 VAC to 123 VAC at the same time every evening, and a reverse change at the same time every morning. As a power engineer, I knew the route that power lines took from the substation to my house, so I drove the line and found a timed capacitor bank about two miles from my house. I drove to that location one evening and confirmed that it energized at exactly the time that I recorded the voltage jump. When I contacted the utility with the information, I learned that it had been disabled when a marine shop closed its doors and no longer had large motors in service. The service agent could not believe that the capacitor bank was in service, so he sent out a bucket truck to check it out. I met the truck at the site, and enjoyed his reaction. Needless to say, he pulled the cutout fuses and shut down the timer. My strange voltage excursions ended. If you believe that your voltage is not close to 120 VAC, be careful to use a known-accurate True-RMS meter to take readings from an outlet that does not have any large appliances or other cyclic loads. The voltage drop in such circuits can skew the measurement of the service voltage. One last thought: A corroded neutral connection at the transformer, or at any point between the transformer and your service panel can allow large voltage swings to occur during load changes. The best indicator of this problem is when some lights momentarily get dim while other lights in the house get bright, each time the refrigerator starts. Since this defect is almost always upstream of the meter, its correction is the responsibility of the utility. 73, Eric Lemmon WB6FLY -Original Message- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, July 06, 2008 8:51 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] High AC Line Apologize for being off topic but a safety question.
