I think you are you using these radios for voting remote receivers?  If 
that's the case, are you sure you want to introduce yet another PL 
response time into the equation?  If not, consider FM'ing the 
transmitters, and installing some sort of audio processor designed to do 
the job of clipping and HPF'ing that fits the situation.  The AP-50 is 
one such animal.  Most commercial equipment audio chain in good from 
only 300 to 3000 cycles; it won't pass PL and it won't pass the high-end 
audio that the voter relies on to properly vote.  The phase modulators 
that most of this equipment utilizes won't properly follow audio that is 
recovered from the discriminator, and is why I choose to install a real 
FM modulator in the radio set.  A better sounding, better working radio 
will result; one that is transparent to the system.  I have never tried 
to FM a EXEC II; we've always used MASTR II's for remote satellite 
receiver - link-back transmitter combo's, but, I don't see why it can't 
be done.

RE: [Repeater-Builder] Quintron Info Wanted

[Paul Finch]

What is the model number of the station.  They made several, the 7792 (I
think was the model) had five distinct transistor PA decks fed into a
Wilkinson combiner, again I think.  It' been a while.  I have a lot of
Quintron manuals but I don't think I ever ended up with a 7792 manual, all
of those stations were on the West coast.

Also, if I remember correctly they all used 24 volts on the final.  Quintron
also absorbed another paging company, Western Radio.  I have no idea what
they used, they were not very good nor were they around much after the
merge.

[Ralph Hogan]

Jeff,

The pwr sup unit for the amp is buried at the bottom of a 6' rack full of
stuff so a little hard to get to the back of it this morning. However from
the front of it the meter 0-3 Full scale indicates:

Grid curr 30 mA
Plate Curr 300 mA
Plate V  3 KV
Fuses on the front:
Filament 1A slow blow
30V  2A s.b.
Cntl 1/2A s.b.

So you know at least some maximums for the plate and filaments. I haven't
fired it up yet, but I saw it in service at the last site it was on. My 150
MHz amp is a 4CX250 tube, not sure about the 440 unit. A manual was supposed
to come with my unit, but the guy moved during the deal and the manual
hasn't surfaced yet. If it does I'll scan it for you.

Re: [Repeater-Builder] Re: Need Help... where can I buy a DSL-Internet repeater...?

[Kevin Custer]

Hi Tim,

Some of the AP and Client equipment we use is assembled from 
parts-pieces.  Some of this stuff , like our 900 MHz gear, is built from 
small computer boards that run a Linux OS and have MiniPCI radio cards 
that make a complete wireless router, ap, or client device.  We use the 
PC Engines "WRAP" and MikroTik RouterBoard.  The RouterBoard comes with 
the OS, however the WRAP you must install some OS on it; for those we 
use StarOS and StarV3.  Building such a system is not for the faint of 
heart, because some knowledge of IP routing is necessary to make it all 
work. 

I have a few NON line of sight paths working on 2.4 GHz.  There are 
amplifiers that can really make a difference with the 2.4 stuff, and 
depending on where you are in the world, they may be legal.  Some of 
these paths run 1 watt of TX rf and have pre-amps for the receive 
signal.  They run very tight 24 dB grid parabolic antennas


2.4 GHz is the cheapest band for internet equipment as there has always 
been a flood of stuff made for it, but there can be a lot of 
interference to overcome.  5.8 GHz is less crowded, but the stuff is 
more money.  900 is nice for NON LOS stuff, but is even more money than 
5.8 GHz stuff.  The 900 stuff we build uses the new Ubiquiti SR9.  It 
has up to 700 mW of power and utilizes the same 2.4 GHz protocol that 
has been refined for very reliable packet transfer.


The Linksys stuff I mentioned earlier is cheap from eBay, like US $40 
each for the devices.  The WET11runs about 100 mW.  Someone else 
mentioned the 200 mW Senao-Engenious CB3 and the 400 mW version.  They 
are very good units as well, but cost considerably more than the WET11.  
One big advantage of the CB3 is it can be either an AP (access point) or 
a CPE (client premise equipment), I.E. Client device.  The WET11 can 
only be a Client.


The use of short feedlines and good antennas are where the most can be 
gained when doing any abnormal shot.  We use 24 dB grids on 2.4, and 15 
dB yagis on 900.  Some of this equipment is able to be powered over the 
Ethernet cable (POE), allowing the radios (repeaters, routers) to be 
mounted right at the antenna; which greatly reduces feedline loss.  The 
CB3 is POE right out of the box.   The WET11 V1 or V2 can be POE'ed with 
modification:




The WET11 V1 uses a standard 100 mW PCMCIA laptop card for the "radio".  
It can be changed out to a higher powered card to do more difficult 
shots.  These days, the CB3, or 400 mW version of it is likely a better 
choice, especially since it can be an AP


Have you tried to make your shot work?  If so, what did you use?

Bill,

You can send your DSL service wirelessly to your home a number of ways.
802.11B (2.4 GHz) is the cheapest, but requires a good near line of site
path. We started using some new 900 cards that seem to work really well
in non line-of-site applications. Scott and I have a 900 path that is 6
or so miles and works great. His end is solar powered! There are
several ways to manage the path as well. If you wanted to serve other
homes than your own, an Access Point will need to be set up at your
office, and client devices deployed at the places you want to deliver
service.

If you have a good path, I'd start with 2, Linksys WET11's and some good
24 dB grids. The WET11's can be bought cheaply from eBay and the grids
new from wlan parts in CA. The WET11's can be set up in Ad-Hoc mode and
will simply be a radio extended Ethernet cable; and with 1.5.8 firmware
is a cheap stable client device for 2.4 802.11B services. There are 2
versions of the WET11, V1 and V2. I prefer the V1 box because it can be
modified with higher power cards if needed.

While this may be a bit off-topic for this list, I'll allow this
discussion as others may want to learn about Internet 'repeaters'.

[Repeater-Builder] Pyramid SVR-200 Repeaters (extenders) on Ebay

[skipp025]

Re: Pyramid SVR-200 Repeaters (extenders) on Ebay 


There's a semi-regular (great) ebay deal on surplus Pyramid UHF 
SVR-200U Mobile Repeaters... aka "extender".  

Just a little background information to potential buyers. 

The mentioned surplus units are older vintage with slightly different 
electronics.  The rf section is nothing like the current version. But 
the logic jumper functions and setup are similar. Staying in the as- 
received 465 MHz range should not require a realignment of the rf 
module/section if it makes the expected spec. 

The SVR-200U can be moved into the 440-450 Amateur Band using the 
earlier version software.  Because the rf-module is a different 
animal you should get your hands on a copy of the now out-of-print 
(unavailable) early SVR-200 Manual.  

I pulled some of my Pyramid Dealer "strings" and found a copy of 
the early rf module circuit diagram and alignment step, which is 
just the ticket to have.  Yes I will make pdf file copies available 
as time allows. 

Otherwise software and the current SVR-200 Service Manual can be 
found for free at/on the Pyramid Web Site. 

Kind of nifty to have an extender on your amateur or commercial 
mobile. In-band repeat is quite possible/easy with the proper 
considerations for layout, rf-protection/isolation and operation. 

Feel free to email me direct if you need more information...

I disagree with your above statement. The DHE voter is not "a rectified 
hf noise circuit".

The Doug Hall Electronics 4RV and 4RV/2 Voters use a log amp and peak 
valley circuits. It is a relative comparator between channels so the 
output is not a S/N value, but the comparison is based on S/N ratio. 
Looking at the envelope of the audio, the peaks are the signal, the 
valley is the noise floor. Signal to Noise.

You may be confusing the DHE voter with the LDG. My understanding of the 
circuitry in the magazine article (that the LDG was based on) is that it 
uses rectified high freq noise.

Early DHE voter production runs used thumbwheel pots, and that made the 
level settings a little touchy.

To the person who is looking for a 4RV manual from 1987, get me your 
mailing address. I'll be glad to send you a copy.

RE: [Repeater-Builder] Re: Quintron Info Wanted

[Paul Finch]

Jeff,

You may be correct, like I said it's been a while since I worked on but I
thought they had 5 finals (50 watts per) plus one that drove the input of
the five finals.  That PA takes about 100 mW to drive it, again not for sure
though.  I will look for a 7792 book.  If I have one there would only be
that one and I don't want to get rid of it but may be able to copy it.  I
also may still have a friend in California that has a couple, will email him
and see.

That PA sounds like a 7792, it does take 24 volts to run that final.  The
station had a funny analog exciter and a FSK adapter that sat just under the
exciter to make it work on digital paging.  They were dependable but a Bear
when they did go down.

Well... maybe the hf noise label is not really 100% right. What I

noise voter circuit vs something like a Motorola or GE circuit. .

There is an ac amplifier, might be a log layout but the following 
circuit is a standard percision rectifier. I never bothered to 
run audio through it to see if and where it might be audio spectral 
focused but it looks like a plain jane audio op-amp percision 
rectifier circuit to me. Call me silly but I don't see anything 
obvious in the circuit picking noise vs signal.

Yep, it looks to be only a comparitor of the channel rectifier 
circuits against the other channels via a reference bus. One of 
the reasons why levels are so critical... loud voice audio in a not 
so well level set-up system can be voted-off same as noise.

Well... isn't the percision rectifier after the log amp pretty 
much changing whatever ac signal it sees to rectified dc? It 
doesn't seem to have any circuit around it that's frequency 
seletive other than maybe an rc time constant before the rect.

[Repeater-Builder] Using a GE Mastr II PLL ICOM in other equipment, like a Motorola Micor?

[Kevin Custer]

Today was another R&D day at Repeater Builder (the company).

Scott and I successfully built an interface module that allowed us to 
use a GE MASTR II PLL ICOM in a Motorola Micor VHF phase exciter.  This 
research is part of development we are doing to produce a plug-n-play 
interface to allow easy installation of a Mastr II FM transmit element 
in several different radios that were originally phase only modulated.  
We hope to make a series of professionally built interface modules that 
will make it easy to "FM" radios like the phase modulated VHF Micor, UHF 
Mastr II, VHF and UHF EXEC II, and the Hamtronics TA series exciters.

We found that the PLL FM ICOM wouldn't drive the Micor exciter directly 
for several reasons.  The biggest reason was the very low impedance of 
the input of the exciter because of the 150 ohm return resistor for 
Meter 2.  The FM ICOM's out is somewhat lower in amplitude than the 
stock K1007 channel element.  After looking at the schematic of a 
KXN-1019B channel element, it was decided that we needed some gain and 
buffering between the GE ICOM and the exciter.  A single stage NPN 
transistor amplifier stage was added between the FM ICOM and the 
exciter; which alleviated all of the interface issues we discovered. 

The 'interface module' PC board provides the 6.1 volt bias for the 
varactor, as well as the 5 volt bias for the compensation line.  The 
interface allows an unmodified FM ICOM to be used; it only needs 
recrystaled (and properly compensated) for your operating frequency.  We 
are looking into putting temperature compensation components on the 
interface to allow the use of more common EC ICOM's to be used, but have 
the same compensation as if it were a 5C unit; or was driven with a 5C ICOM.

We have successfully used PLL ICOM's in UHF phase Mastr II,  VHF phase 
Mastr II, and now the VHF phase Micor. 

Why are we doing this? 
1, True FM UHF Mastr II's are VERY scarce.  This interface allows you to 
have the same desired FM audio, without paying the BIG price for the 
real FM UHF Mastr II exciter.

2, While you don't have the better phase noise advantage with a FM'ed 
VHF Mastr II phase exciter compared to a real PLL Mastr II VHF exciter, 
the phase exciter is much more common. 

3, In the Micor VHF, the KXN-1019B's are getting hard to come by.  This 
interface allows you to use a FM ICOM even in a 3 pin phase exciter.

The interface will also allow easy connection, and possibly mounting 
area, for the RB AP-50 audio processor; which will be great for those 
wanting to do away with the stock audio path totally.

Comments - Questions are welcomed...
And, a question for you folks...  Should we consider this retro-fit in 
any other equipment?

Thanks,
Kevin Custer

Kevin-
YES!!  Could you also build an interface so we can use it on A series and G
series Motorola Transmitters?  (That would be nifty to replace the crystal
heaters!

On a more serious note, how about 
1. a Motrac interface?
2. a Mastr Pro interface?

[Repeater-Builder] Characteristics of old spiral 7/8" hardline

[Nate Bargmann]

Does anyone have the loss, VF, and other electrical characteristics of
the older spiral style 7/8" hardline (where the outer shield's shape
resembles a screw rather than parallel ribs)?  It is the type that
uses the shorter connectors than the current Andrew Heliax offerings.

I'm working out the load SWR and loss of a site that has this older
coax installed and none of my current books make any mention of it.

John,  Please refresh my memory.  Isn't the fundamental for the Mastr 
Pro around 8 MHz?  I'm not sure if the crystal manufacturers could 
produce a quality-stable 8 MHz fundamental crystal that would work 
correctly in the PLL ICOM, or vice-versa.

I think the Motrac used a 12 MHz fundamental so that wouldn't be a problem.

In the equipment we have done testing on, all have used a 12 MHz 
fundamental (or thereabouts), so the ICOM is running within its OEM 
specifications.

[Repeater-Builder] CTCSS Tone Encode on Mastr II

[Jim Cicirello]

Hi Guys, 
I can use a little advice on hooking a TS32 to a Mastr II. I am using
a new TS32 for encode only on the Mastr II TX. I have injected it into
the exciter where the stock encoder went, pin 2 on the exciter which
is adjustable with the CTCSS Pot on the Mastr II Exciter. I am using
203.5 Hz and at 750 Hz deviation it sounds like the deviation is much
greater than 750 Hz. When the courtesy beep and the ID sounds, I can
hear a little mixing and the tones are not a clear as it is without
the CTCSS. I understand that the PM Exciters sound a little different
so I used the 100K resistor in series with the tone output and put a
.1 uf cap to ground. All this does is pull down the deviation to way
less than 750 Hz and when I adjust it back up, there is no different
than using the output of the TS32 direct to the exciter. Am I missing
something that I may do to clear up the TX audio. 

Re: [Repeater-Builder] CTCSS Tone Encode on Mastr II

[Kevin Custer]

Tuning can make a big difference in the distortion of modulated audio in 
a PM exciter.  Are you sure the exciter is tuned up properly?

[Repeater-Builder] Re: Need Help... where can I buy a DSL-Internet repeater...?

[kb2mfs]

No I haven't tried it yet.  I did some modeling and with 150mw, 20dbi 
antennas and the antenna at the friends house mounted up 21 feet (he 
doesn't have a tower and isn't a Ham) and the antenna mounted at 
least 60 feet up my tower it showed a good path.  This was 7.22 Km 
and despite the non line of sight.  I was hoping for 2.4 Ghz 
equipment since it is readily available running 200mw and 24 dbi 
antennas.  I had also planned to mount the units at the antenna 
point.  I was just second guessing the software models results.  I am 
pretty cheap so didn't want to spend the money on equipment if I 
wasn't reasonably sure it would work.  

I have never used anything near 2.4 Ghz but I would think it would be 
rather difficult to line up the antennas.  Other than a rough guess 
what is the best way to do this?  It looks like every milliwatt may 
matter in this installation. 

Thanks for your help and the explanation of your systems.

RE: [Repeater-Builder] MVP - PLL

[Jeff DePolo]

Dave KA9FUR designed a complete ICOM replacement board, which included an
audio processor, that fit into a standard PM ICOM shell - plug n' play.  I
have a few of them, but I had some problems which I think Dave latter fixed.
It's probably been close to ten years since I've tinkered with them.
 
Mention was made of how to deal with compensation.  I've built ovens of
various types, and even used PTC thermistors soldered directly to the case
of the crystal as a heater, with good results.  I think Bob NO6B did the
same - you QRV Bob?  Re-creating a complete FM ICOM replacement, such as
what Dave did, including a modulator and compensation (or oven/heater) seems
like it should be pretty easy and cost-effective, and eliminates the need of
trying to find 1C/2C/5C FM ICOM's.

Been there done that (Only UHF MII & MVP). The same PCB (audio
processor) is used on both exciters but  and plugged  onto the original ICOM
pins (see attached photo) 
 
In my opinion it's the best thing you can do for these radios!

Well, that's not exactly true.  The Maintenance Manual for the R2600 Service
Monitor is definitely available from Motorola Parts as Part Number RLN5237A
for just $350.  This is a CD-ROM with everything you could imagine on it.

The R2600 series of service monitors has always been made by General
Dynamics, and only recently has been offered for sale under the General
Dynamics label instead of a Motorola label.  You might get a better deal by
contacting General Dynamics directly.  In the case of the R2400 series
service monitor, GD probably has that manual available.  Go here:

Re: [Repeater-Builder] Re: Need Help... where can I buy a DSL-Internet repeater...?

[Jack Davis]

The secret is to cut the losses as much as possible.  The best way is to mount 
the access point or bridge right at the antenna in a weatherproof box and feed 
it with outdoor cat 5 cable using power over Ethernet (POE).  The RF jumpers 
are short and the loss is minimized.  It may be of some benefit to use 
horizontal polarization on your path, most WIFI  and ISM signals tend to be 
vertically polarized and the cross pol may provide you with a benefit.  You may 
find that you have plenty of signal but not much throughput, this can be caused 
by the acknowledgement (ACK) window being too short, what happens is the 
propagation delay on a long path causes the receiver to stop listening before 
the packets arrive.  The long range radios have an adjustable ACK time to 
prevent the problem.  I like the Linksys WET-11's, they are a bridge that can 
be configured with an access point (AP) or a pair of them in a peer to peer 
mode.  They are inexpensive and readily available on the used (e-Bay) market. 
Another interesting item is the Ubiquiti LightStation modules, they come in 
both 2.4 and 5 GHz models. http://www.ubnt.com/litestation2.php4 .  The 5.8 GHz 
band is actually better for point to point use, it is less crowded and the 
antennas are more directional.  I have a 5.8 Path that is 42 miles long and it 
is extremely reliable but I am using some 10 and 8 foot dishes to get the gain 
up and I have yet to catch it fading.  I recommend that you stay with 802.11b 
or a, forget about the g as the receiver sensitivity goes down with extra 
bandwidth and they become more prone to fading.  11 MB/s is fine for most of 
what you need and it is faster than DSL or most cable modems.
