[Repeater-Builder] Need Maxar/Moxy power connector

2008-11-29 Thread kb9bpf
Howdy all,

I need to find a handful of power connectors for some old Maxar/Maxar-
80/Moxy radios, the ones that have the two larger  (0.093 Molex) pins 
for power and then use smaller (0.062 Molex) pins for the other 
fifteen test set connections. Does anyone on the list have a few they 
can spare? Will happily pay fair price and postage. 

You may contact me directly at mycall at arrl dot net.

[Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups

2008-11-29 Thread georgiaskywarn
Getting ready to purchase a TXRX dups for my UHF repeater.  Repeater
will be running about 100watts into the dup.s. Will be buying new.
Suggestions on model numbers to look for?  Is the TX/RX brand what I
need to be looking at (for the best BP/BR dup.s)?  Currently running
the Moto series 1500 (BP/BR).

Robert,

 

I would have to agree with Chuck, the TXRX brand is hard to beat. Now you
want isolation, Just keep in mind that the noise floor is rising and what
you purchase today will not be the same as if you purchase it in five years.
Bigger is always better and at sites today you can't go wrong with going
over kill on the filtering. If you get the standard 4 cavity BPBR duplexer.
You can have them add a extra band pass to both the TX  RX side for some
extra out of band protection. When you get the duplexer add a TX isolator if
your repeater does not have one built in like the Motorola MTR2000. Anymore
us hams need to keep our stuff cleaner than the commercial guys. For the
most part a lot of us do so but there are a few that really skimp and make
it hard for the rest of us when dealing with sites.

 

If you decide to go with Sinclair here is one on EBay that looks new and
will perform as good or better than the TXRX and is just an
option/comparison in duplexers.

Robert,

There is nothing wrong with the T-1504 series duplexer if it if properly tuned 
and adjusted, and unless you have money to throw away to bolster our sagging 
economy you arn't going to accomplish a lot in the process.  I just retuned a 
set of 1504A's the other day for 443/448.325 and got 80 DB of isolation from 
each side, with an insertion loss less then 1.5 DB. 

Interconnect cables are easy to make for the 1504's and the service manual 
indicates the proper length of each cable for the freq. range you want to tune 
to.   

It's a lot easier and less expensive to add additional cans for greater 
isolation or filtering to the duplexer you have then puchase a brand new 
duplexer.   

Let me know if you need some help with this and I'll see if I can work 
something out with you about getting together after the Holidays.

The UHF 4 can TX/RX duplexer will give you around 100 dB per side with 
typically less than 1 dB loss.

Our economy needs a boost ;-)

You can always keep the old ones as an emergency spare.

RE: [Repeater-Builder] Suggestions on UHF - TXRX BP/BR dups

2008-11-29 Thread Eric Lemmon
Robert,

Motorola sold a gazillion 100 watt UHF Micor repeater stations equipped with
the T-1500 series duplexers, and many of them are still working just fine
today.  I'm curious:  What is prompting you to replace your existing
duplexer?  Is your repeater an original Micor, or some other brand?  I ask
these questions because I don't see the justification to spend nearly two
thousand bucks, if no real improvement results.

One option you might explore is the addition of a bandpass-only cavity on
each side of your existing duplexer, or at least one on the transmit side to
clean up any sideband noise from the PA.  Some aftermarket PAs are
remarkably trashy, and a bandpass cavity can do wonders to improve the
station operation- especially if receiver desensing is being caused by
transmitter noise that falls on the receive frequency.

[Repeater-Builder] How to set up a basic crossband repeater system in Public Service

2008-11-29 Thread bkcarter33
My local Community Emergency Response Team (CERT) has recently 
obtained a UHF repeater (ICOM CY-F221S).

It has two ICOM F221S radios linked together in a nice rack mount box.

It has also been set up with a remote mic and speaker off of the 
outputs on the chassis back panel.
The CERT group is licensed for the UHF repeater frequencies and they 
are in the public service band. They also have a simplex VHF 
frequency in the PS band (old police frequency) licensed.

They have a number of Motorola HT radios (CP200) that operate on the 
simplex VHF frequency. 

They are looking at obtaining additional UHF HT radios in the future 
but would like to be able to use the equipment they have if they can 
get it to work together.

I am familiar enough with electronics to be able to follow 
directions, but not enough to design anything beyond a basic switch 
box.

I am a network engineer professionally so I am pretty well versed in 
those areas, and understand logic control pretty well.

I am a technician class ham, but don't know a lot about RF as I have 
not had that much experience in it.

I would like to accomplish the following and would love to receive 
some guidance from someone who has the knowledge to instruct me:
I would like to set up a cross band link for them from the UHF 
repeater, to a VHF radio:

This would allow someone on the UHF side to transmit to the repeater, 
and also cross-band repeat to the VHF side.

The VHF side would be able to transmit on the VHF simplex frequency 
to the cross band side, and it would repeat onto the UHF side.

I realize that this would NOT provide VHF to VHF repeating, and that 
is okay.

I want to provide a way that the cross band link can be enabled and 
disabled by remote DTMF tones so that the bands can be separated when 
desired.

I already have an old Motorola Spectra police radio operating on the 
VHF side at the site, and it has a dedicated antenna. It puts out 
110W which is way too much for what we need. 

I was thinking about getting an ICOM F121S radio, Astron power 
supply, and ICS basic controller board.

Using the existing VHF antenna, I would hook up the new ICOM (50 
watts or less).

Now I just need to tie the ICOM repeater, controller, and new radio 
together into a cross band system of sorts. 

Am I on the right track?  I need some general guidance that can tell 
me, try this, this, and this. Here is what equipment you could use, 
and here is how you could tie it together. I have the schematics for 
the repeater available to me.

If I don't want to spend the money for a new ICOM F121S radio, then 
what else could I connect easily that I can program and would be able 
to get at a reasonable price.

This is all being done as volunteer service so inexpensive is best, 
but I want to avoid cheap equipment.

Thanks for any help you could provide me,

You probably already know you need to find tx audio input, squelch 
gated rx audio output, ptt  COS or TOR.

COS is carrier operated relay  TOR is tone operated relay.
Preferably you'll use TOR as the active low output to key the vhf ptt.

There's software settings to make these I/O's as you need them.

It is necessary to adjust audio levels into  out of each radio.
This can be done with series resistors or attenuator pads.
Chances are you'll need to use caps to equalize the audio as well.

Ideally you'll have a service monitor available to check all this.

In lieu of the SM, you can carefully compare between the uhf  vhf 
sides for best match of tone quality  levels.

Wish I had the tech info near me but it's all at work.

You might find a way to use the dtmf decoders in each unit along with 
some type of latching relay to perform your control functions.

I'm pretty sure there's I/O for the dtmf decoder available on the 
accessory jack.

Re: [Repeater-Builder] How to set up a basic crossband repeater system in Public Service

2008-11-29 Thread Jim Brown
Bryan, I can recommend the NHRC-4 controller for the service you want to 
implement.  I'm not sure but I think the ICS-Basic you mentioned is a repeater 
controller that does not have the second port to control your link.

I have built up 3 of the NHRC-4 controller kits and used them in two port 
service where the main port controls a repeater and the second port controls a 
simplex radio on another band and can recommend them for this type of service.  
They were easy to build, and the later control system is very easy to set up 
using the zone type of control groupings.  I ordered the remaining parts from 
Digikey for my controllers, and the suggested part numbers in the manual work 
out fine.  With a well stocked junk box, you may have a lot of the parts.  I 
did not have to order a single resistor or bypass capicator for my kits.

You could probably get started using the existing VHF radio, and if it proves 
to have too much coverage you could change the radio.  When working with hand 
held radios you may find that the extra power is useful even when the handhelds 
can't talk back to the simplex port.  Being able to copy EMCOMMS even when you 
can't talk back can be of some use.

Finding the correct interface for the radios to the controller can be a pain, 
but can usually be accomplished.  The NHRC controller can handle receive audio 
that is already equalized, or can equalize the audio from the receiver 
discriminator inside the controller.  Same with the receive audio from the VHF 
simplex radio.

I want to provide a way that the cross band link can  be enabled and 
disabled by remote DTMF tones so that the bands can be  separated when 
desired.

I already have an old Motorola Spectra  police radio operating on the 
VHF side at the site, and it has a dedicated  antenna. It puts out 
110W which is way too much for what we need.  

I was thinking about getting an ICOM F121S radio, Astron power  
supply, and ICS basic controller board.

Using the existing VHF  antenna, I would hook up the new ICOM (50 
watts or less).

Now I  just need to tie the ICOM repeater, controller, and new radio 
together  into a cross band system of sorts. 

Am I on the right track?  I  need some general guidance that can tell 
me, try this, this, and this.  Here is what equipment you could use, 
and here is how you could tie it  together. I have the schematics for 
the repeater available to  me.

If I don't want to spend the money for a new ICOM F121S radio, then  
what else could I connect easily that I can program and would be able  
to get at a reasonable price.

This is all being done as volunteer  service so inexpensive is best, 
but I want to avoid cheap  equipment.

Thanks for any help you could provide  me,

 I have an assortment of Moxy and Maxar radios in my shop, and every one of
 them has a 15-contact Molex connector on the back- and all contacts are 
 the

[Repeater-Builder] RLS1000B question

2008-11-29 Thread georgiaskywarn
I have a RLS1000B connected to a RC210.  I have a 220 link radio on
the RLS1000B and the RC210 is connected to a UHF repeater.

The TX audio from 440 to 220, PTT on 220 (when the 440 is keyed), COS
from 220 to 440 (which then keys the 440)is all fine.

However I can't get 220 audio back to 440.  I checked connections and
everything is fine.  I plugged the 220 radio directly to the RC210 and
works great.  I have a plug in line to switch some pins around to
make that cable work when plugged into the RLS1000B.  Checked out fine.  

The paper I have on it is real dim on details.  Tried the RX pots on
both units...no joy.  Almost as if it doesn't have enough signal or
something.

Ideas?
Thanks,

2008-11-29 Thread kb9bpf
I have two Maxar-80 which have the oddball connector on it, a VHF 55W 
unit model D43TSA6000AK and a UHF model D34TSA6000AK which I think is 
rated at 25W but during tuning would do 44W until backed down. (I 
don't have the exact manual for a UHF Maxar-80 so I don't have a UHF 
Maxar-80 model chart available but the other Maxar and Moxy manuals 
are close enough for tuneup.)

I found a reference to the connector we're speaking of, which mates 
with connector J601, in Maxar 450-512 MHz manual 68P8103E10-O. 

P610, Connector, Plug: 
Includes: 
15-83958L01 Housing 17 pin
29-84706E02 Terminal, male' 9 required
29-82335A03 Terminal, male; 2 required 

I don't need the male terminals because they are standard Molex pins 
and I have a drawer full of them. I need a handful of housings, two 
for the radio plus at least one extra to make test connectors.

Thanks for your help,

And loss of a license would adversely affect the ability of any PS 
agency to do their job. You would be essentially putting them out of 
business. Then, the municipality could come after you for the costs to 
pay another municipality to cover their area. After all, they only have 
to pay because YOU made them lose their license, and they are under 
legal obligation to provide at minimum fire protection (well, at least 
in PA they are).

It can get very expensive very fast. Is it worth losing all your 
possessions and perhaps doing some jail time over saving a couple 
hundred or even a couple thousand dollars for doing it right? Also don't 
forget the suits from anyone adversely affected by the lack of or 
delayed response from emergency services. They will be in line to sue 
you, too.

And you better pray it's not the county who loses their license - 
affecting PS agencies in the entire county.

I'm sorry... the number you have dialed 9 1 1 is no 
longer in service. John Smith wanted to save a few bucks.

Oh, and if you have a ham license? Write that off, too, as well as any 
other license you may have held.

Yes, all of the licensing is in place for both sides (spent last year 
doing that). The VHF side is the old city Police frequency and we are 
not doing anything they weren't doing except for the cross-band to 
UHF.  We won't repeat VHF so I think we are okay. Locations and ERP 
are all correct.

2008-11-29 Thread bkcarter33
To be honest, I'm not sure at this point what I really KNOW :). What 
I am trying to do seems so simple in a logical way to me, but knowing 
what inputs and outputs to use for what is all new to me when it 
comes to RF. 

I do have folks around with service monitors, and somew knowhow, but 
I am trying to get a parts list together so I can purchase the 
required pieces while the $$$ is available to me (another story 
there - I told them I thought this could be done for under $500 so 
they said do it).

Anyways, the back of the repoeater has a DB25 jack with the following 
I/O availabe:

6 Vcc TX +15V DC Supply for External Controller, TX Unit Maximum 1 A
7 GND TX DC Ground, TX Unit
8 Busy TX Output Terminal for Busy Signal, TX Unit
9 AFO TX Audio Output, TX Unit
10 DISC TX Discriminator Output, TX Unit
11 TXA TX Transmit Audio, TX Unit
12 PTT TX External PTT, TX Unit
13 TXD TX Transmit Data Input, TX Unit
18 Vcc RX +15V DC Supply for External Controller, RX Unit
19 GND RX DC Ground, RX Unit
20 Busy RX Output Terminal for Busy Signal, RX Unit
21 AFO RX Audio Output, RX Unit
22 DISC RX Discriminator Output, RX Unit
23 TXA RX Transmit Audio, RX Unit
24 PTT RX External PTT, RX Unit
25 TXD RX Transmit Data Input, RX Unit

I also know that I can get a OPC-617 cable for the Icom VHF radio 
that brings the I/O outside the chassis.

Maybe I am not explaining the DTMF portion correctly, but I just want 
to be able to bring the crossband repeat function up and down 
remotely using a tone code.

This is exactly what I need though as I am not sure what all of these 
I/Os will do for, or against me, and I know better than just to try 
to connect wires together.


Thanks

 COS is carrier operated relay  TOR is tone operated relay.
 Preferably you'll use TOR as the active low output to key the vhf 
ptt.
 
 There's software settings to make these I/O's as you need them.
 
 It is necessary to adjust audio levels into  out of each radio.
 This can be done with series resistors or attenuator pads.
 Chances are you'll need to use caps to equalize the audio as well.
 
 Ideally you'll have a service monitor available to check all this.
 
 In lieu of the SM, you can carefully compare between the uhf  vhf 
 sides for best match of tone quality  levels.
 
 Wish I had the tech info near me but it's all at work.
 
 You might find a way to use the dtmf decoders in each unit along 
with 
 some type of latching relay to perform your control functions.
 
 I'm pretty sure there's I/O for the dtmf decoder available on the

Mike,

I appreciate your response and concerns. I should have mentioned in 
my original post that I am either the the representative of the 
license holder (Kaysville City) for these frequencies, or in contact 
with the person who is. 

I have not thus far used any equipment on the public service band 
that is not typed for that band, at least as far as I know. Nor do I 
intend to.

We hired APCO last year to get everything squared away on the 
licensing for the repeater and that was a chore and a half. I don't 
want to do anything to put that in jeapordy.

However, if I have all the permissions lined up, which I think I do; 
have all the licenses in place, which I think I do also, I need to 
find the best way to accomplish the task.

One problem with working with volunteer organizations such as CERT is 
that everything has to be done, well, volunteer. We were able to get 
a grant for some money to get the repeater, and pay APCO to do the 
licensing, but that source has dried up. We have equipment, and 
people willing to do the work, but need to keep the professional 
costs to a minimum, without creating any problems for the local 
authorities. If I had $$ to spend, where would be the best place to 
spend it? My thoughts right now would be to have someone with a 
Service Monitor check our work after we are ready to plug everything 
in. I can connect wires, solder, and program without any issues. Even 
using the proper shielding, etc. if I know what needs to be connected 
where, and why.

I agree that this may not be the norm for a lot of people, but we 
have done a LOT of work to keep this all within the proper 
authorizations and permissions.

Thanks

Bryan
