Re: [Repeater-Builder] Question on portable repeaters

No worries. They have an SUV roof. 

Vertical and horizontal distance with be significantly different, with vertical 
being smaller. You should look onto a mobile duplexer. They are relatively 
cheap.

Ya, you CAN program 100 or more repeaters into most current commercial rigs, 
and alpha tag them as well.

 W.r.t. the primary public service event I'm involved with (LA Marathon), we 
 simply don't allow untrained individuals to volunteer; pre-event training

 This has nothing to do with "new repeaters". Out of all the repeaters 
 serving the area, can you predict which ones will still be on the air after 
 a disaster? If not, can you program every single one of them into your 
 commercial radios? Around here it would amount to nearly 100 repeaters 
 just on 2 meters.

 I guess the other areas can speak for themselves w.r.t. "allowing" new 
 repeaters. Here in SoCal there are new repeaters hitting the airwaves 
 nearly every month.

Maybe it is not too late to "turn down" the contract.  Did you really think you 
would be able to get them licensed to a VHF pair, or were they not totally 
upfront about what they had and wanted.  

You can't control what the FCC allows. 

You could just make a go of it with a simplex system.

I have seen the license for the UHF pair that they have but the hotel is
not interested in purchasing new equipment for the current system of VHF
radios was just bought last year. I got stuck with this project of
getting a repeater pair and programming the radios. If I would have
known the system was so jacked I would have turned down the contract.

Peter,

What type HTs do they have.  One does not see HTs with mWs except for
PRS, the small cheap radios in the 462 range.  So their HTs might have
power, 2-4 W, to cover the grounds.

As you proably know the UHF would get out of holes (hotel walls, etc)
better, but guess not an option.

Covering the 50 acres is no problem, covering from inside
rooms/hallways, etc can be.

I would try for a remoted base with roof antenna.  This will not improve
HT-HT coverage, would give someone better coverage which is probably
important...if the management can talk this often determines if the
system is working.  Few listen to the people who actually do the
work...way it is.

Another solution would be a repeater, low power, 10 W.  Mot has some
very good GR300 using couple of their Radius line rigs mounted in a box.
Since commerical would require 2 freq and if 5 MHz apart could use
mobile type duplexer.  All fits in a small 10w x 10d x 12h or so
including power supply.  The HTs would probably need to be reprogrammed
and the proper license obtained.

This is a common "problem" on e-mail reflectors, and message boards.  No one is 
saying "don't ask/post/e-mail". They are saying, search the web, and read the 
information, and if you still have questions, then ask.

You stated you know the law. Not sure which law school you went to, or how they 
worked, but in my school, you learned by reading cases, briefing, and then 
being called on in class. Sure, sometimes you won't understand the concept, and 
need to ask a professor to clarify. Same is true on the web. Read the info, and 
try to understand. If you don't get the concept, ask the professor (the 
knowledgeable people) for clarification. What do you think would happen if you 
walked into class one day, and asked the professor to explain Torts?

MFJ marketed that board also. I think it was an
 MFJ-52, but not sure.
 
 You have to make a packet connection to the TNC using
 the X1J4 firmware and the TNC will respond with the
 deviation and signal strength of each station in the
 MHeard list. You can also query for supply voltage
 and temperature. I am sure you could substitute power
 out and power reflected for the last two params, and
 use the repeater as a packet node to get these values.
 
 I just installed a regular packet node on a
 mountaintop and used one of these boards, but did not
 hook up the hardware for the voltage monitor or
 temperature. The deviation and signal strength come
 in handy for keeping up with the various packet
 stations the node services.
 
 The receiver condition could also be monitored using
 this setup and connecting from a fixed location with a
 power output that would not saturate the first limiter
 of the receiver, where the signal strength is picked
 off. The most stable signal strength I found was from
 another node about 150 miles away that normally read
 about S-8 but would vary with the weather conditions.

Re: [Repeater-Builder] Bluetooth for ham use? Gen rundown on Bluetooth?

[michaelhq54]

The units mentioned in the previous post are units that act as a bridge between 
the audio and BT connection. They are used to add BT to a phone (or ham radio 
in this case) when one did not exist before. The unit plugs into the regular 
2.5mm plug on the phone used for a headset and converts it to bt, so you can 
use a BT headset instead. 

You can probably rig something together for a ham radio, using a VOX and the BT 
connection for audio.

 Please pardon the dinosaur novice question: I know generically of the 
 concepts of Bluetooth, though I don't use it and never have.
 
 If used with a cell phone/full duplex, I can understand.
 
 If used with an amateur transceiver, is there a PTT interface 
 implemented, or how to you to the half simplex route from radio to 
 headset?
 
 If I buy the proper equipment (or say my phone already has Bluetooth, or 
 my computer), can I use the same handset alternately for cell phone and 
 amateur?
 
 This would be for flexibility at the desk, not mobile or portable. I am 
 100% deaf in one eat and 80% in the other, and I usually need some sort 
 of electronics, or an empty house where I can turn the RX audio up WAY 
 loud, or headsets, to use amateur HF or VHF, or the headset on my cell 
 phone. Of course I use PTT on the amateur.
 
 A general rundown or source would be appreciated. I looked at Jabra's 
 site and they say very little, and the page with the A210 tries to play 
 an SWF file which my machine says is corrupted.
 
 In the meantime I stick to a Saber for amateur, whose batt is larger than 
 my wife's entire Yaesu VX-7. 
 
 Does Bluetooth for cell phones simply cut out the headset cord, which 
 really is no problem and needs no batt maintenance. Or is there more to 
 Bluetooth which I don not understand? Does this count for hands-free in 
 states which require it? Still seems a joke as you have to pick the phone 
 up to dial, or to see who's calling and if you want to answer. I doubt 
 the traditional car kits are sold for new Motorola cell phones anymore, 
 with the external roof antenna, batt charge, handset hanger, ext speaker 
 and amp, and ext mic. We use ours, but actually coverage is so excellent 
 with Verizon all we use them for now is batt chargers.
 
 And the black Startac base station, with ext ant capability and handset, 
 speaker phone, etc. -- are they still made? I use one of these for my 
 desk phone and all long distance. Like a base convertacom for the Startac 
 7868. Those two accessories (Car kit and base) have kept me on these old 
 Startacs, plus the Startacs work supremely well and have been zero 
 problems. Getting hard to find batts though. All the ones from the 
 surplus houses have the same 5 or more year old date codes as the one I'm 
 using. Good, loud, crisp audio, and rugged, and not much more than a 
 basic phone. With my wife and me both using the same car kit, desk set 
 and handset, we can plug in whichever phone wherever we are. Can that 
 still be done?
 
 I made the mistake on stocking up on spare, low hours used 7868 Startac 
 phones, but now Verizon won't commission them because of no E-911 
 capability. Guess that was a waste. If anyone needs some 7868 working 
 CDMA/Verizon handsets, LMK. Of if anyone has any new FRESH bubble 
 batteries for Startec, preferably OEM, please LMK.
 
 I'm using a fossil antique digital Startac, but when it croaks Verizon 
 tells me I'll have to go to an E-911 capable phone, which in the 
 Baltimore area here means GPS. Will be interesting because I rarely am in 
 the open where the thing could get GPS lock. 
 
 Hi to my friends here, esp Dave Van Horn. Good people.
 
 Appreciate the generousity of those on this list.
 
 
 
 I presume everyone here is familiar with the Private Wireless Forum,

 well disciplined fully moderated list: Note I said it is busy.

Re: [Repeater-Builder] Temperature controlled fans

[michaelhq54]

Check out www.allelectronics.com. They have several temp switches, that open 
and close depending on the temp. Not sure if they have the temp you need, but 
they might have something that would work, and they are cheap.

Subject: [Repeater-Builder] Temperature controlled fans

Hi all
 
 I am building some solar powered repeaters and a 
 crossband link utilizing motorola maxtracs and gm300's
 they will be built in nema boxes and will have fans 
 installed for ventilation and cooling.
 
 What I'm looking for is an inexpensive way to control
 the fans, I would like the fans to kick on at around
 75 to 80 degrees and kick off below 75 degrees, this 
 way the fans wouldn't be running during the cooler night 
 hours conserving battery power while there is no
 sun.
 
 can somebody recommend a fixed or adjustable temperature
 switch to accomplish this that could be attatched to 
 a heat sink or inside the box.
 
 Thanks
 Steve

Re: [Repeater-Builder] Spectra radios as repeaters

[michaelhq54]

What are you trying to accomplish. Are you trying to enable communications from 
handheld to handheld accross your town, or are you trying to improve the 
receive coverage of the base setup at the firehouse??

That difference will determine your options.

Subject: [Repeater-Builder] Spectra radios as repeaters

Group,
 
 I have a couple of Motorola Spectra radios ID# T83FWA7HA9AK with 
 HCN1073D remote heads on them. These guys are the full trunk mount 
 radio that came out of some police cruisers when they moved to 800 
 Mhz. We use them on the 155.xxx frequency band for our city CERT 
 (Community Emergency Response Team). We have Motorola HTs that are 
 programmed to the same frequency but obviously limited in range (5 
 watt). We have the Spectra at the Fire Station in the middle of 
 town, with a tuned antenna sitting on the roof (about 15 feet up on 
 a mast) and we can reach the entire city with that 110W of power. 
 
 So, we would like to put in a repeater, but cannot afford one. 
 
 Is it possible to tie two of these radios together to create a 
 repeater system? What would be required to do so and how would I go 
 about doing it?
 
 Or, am I barking up the wrong tree with this whole idea?
 
 Any help would be greatly appreciated.
 
 Thanks

 Those laws are also a direct violation of the constitution.
 
 
 
Oh sure, you can say that all you want from the inside of the cell.  Good luck 
on your quest!

Well Jim, your lack of legal knowledge astounds me. Please tell me how a 
restrictive law as mentioned here is a violation of the Constitution. Please 
point me to the Amendment being violated in particular. 

Michael
