Greetings,
We recently transfered the club's sharc.net domain to the same
company that hosts our sharc.org domain. We did this because the
customer service support under the current hosting company has become
practically non-existent.
As a result of this change, we will now be able to provide members
with sharc.net email addresses in addition to sharc.org email
addresses.
This service can be set up a couple different ways:
1. A member can have their sharc.net/sharc.org address forward all of
their email to their home email address, thereby shielding their home
email address.
or
2. They can log-in to the host's website and read & send mail from
there. When sending email, the email address that you will be sending
from will be from @sharc.org or @sharc.net.
Q. Ok, so some of you might be saying, why would I need a sharc.org
or sharc.net email address?
A. If you move and/or change ISP's, your email address always stays
the same. Members can also change their email set-up in "real time"
anytime they want, 24/7.
Q. How secure is it?
A. All email is stored on the host's system, just like your current
ISP. No one will have access to your account except you.
Q. What kind of an email address can I have?
A. Anything you want. Ex: YOURCALL@... or YOURCALL@...
Q. How do I get a sharc.org or sharc.net email address?
A. Just email us and request one. Tell us what you want your email
address to be and we'll set it up. We'll give you a temporary
password to initially log in. Once you log in, you can then change
the password to whatever you like.
Q. What about spam filtering & virus scan detection?
A. We provide both spam & virus scan protection! Just log into your
account on the host's website and you can set your preferences for
either.
Q. Can I send and receive attachments?
A. Yes!
As for the club's website, the domain change will be transparent to
the user. We hope this change will provide better customer support
to the club and its members. If you are interested in obtaining
one of these email address, drop us a line at: ks3r@... or

Greetings,
A new duplexer has been purchased for the SHARC-2 Repeater (442.500
MHz). It is expected to arrive om June 8th. The new duplexer is a
Sinclair Model Q3330E, 6-cavity.
The current duplexer is a Phelps-Dodge model which we will be posting
on Ebay for sale.
We will also be replacing the cables between the duplexer and
repeater with superflex (100% shield) heliax.
There are also plans to replace the stock RCA pre-amp with a
GaAsFET pre-amp.
We'll keep everyone posted on the repeater's progress.

Greetings,
Both the SHARC-1 & SHARC-3 repeaters use the same type of repeater
controller.
On both repeaters, the "anti-kerchunk" function is currently
enabled. What this means is, that when there has been no activity on
the repeater for at least 20 seconds, the repeater must receive a
constant carrier for a duration of 2-3 seconds in order to be keyed
up. Once this happens, the repeater will revert back to being keyed
up instantly upon receiving a carrier.
After 20 seconds of no activity, the controller revert back to "anti-
kerchunk" mode and will not key up the repeater again until it senses
another constant 2-3 seconds of carrier at the receiver input.
The "anti-kerchunk" function is used to help reduce the number of
times the repeater may be keyed up due to noise, interference or hams
with an itchy glitch finger. This helps saves the wear and tear on
the repeater as well as the nerves of the control ops (hi-hi).
We'll be posting open commands and features of the new repeater
shortly.

Greetings,
It's been a busy weekend with the SHARC repeaters. Here's what was
accomplished:
May 22, 2005: SHARC-3 - 51.940 TX / 51.440 RX
Mark, N8UVQ and Jim, KA3EBX met up at the SHARC-2/SHARC-3 Repeater
site and installed a GaAsFET Pre-amp on the SHARC-3, 6 meter
repeater. Mark purchsed the pre-amp from Advanced Receiver
Research. The model number is P50VDG and has +24 dB of gain. Mark
and Jim tested the pre-amp with a Wavetech, Model 3501 signal
generator.
To obtain a point of reference, they fed a signal from the generator
directly into the repeater's receiver. The signal was modulated with
a 1 kHz tone. The signal generator level was then gradually reduced
to determine the receiver's sensistivity. They found that with the
generator set at .15uV, the received signal was extremely noisy &
choppy, often dropping out below the repeater's squelch setting.
With the pre-amp installed and with a 10 dB attenuator pad inserted
between the pre-amp and receiver(to minimize receiver front end
overload), they found that with the same input level (.15 uV), the 1
kHz modulated signal was perfectly readable with only minor
background hiss. It was also discovered that an input signal level
of just .07uV was enough to break the receiver's squelch.
May 22, 2005: SHARC-2 - 442.500 TX / 447.500 RX
Jim and Mark also touched up the SHARC-2 repeater's transmit
frequency which had drifted a little.
May 22, 2005: SHARC-1 - 145.130 TX / 144.530 RX
Jim and Mark put together the SHARC-1 repeater's new Hustler G7-144
base antenna and mounted it on a 10' mast which was temporarily stuck
in the ground in Jim's back yard. Before connecting it to the
repeater, the SWR was checked using a Yaesu VX5, 5-watt handheld and
Bird, Model 43 wattmeter. Using 1/2" superflex with "N" connectors,
The repeater was then connected to the duplexer and turned on. No
problems were observed.
The SHARC-1 Repeater will be occasionally on and off the air while
we complete all of the wiring and testing. The best time to try and
key it up will be in the evenings after 5PM. Remember, the repeater
and antenna are not up at the repeater site yet, so coverage and
sensitivity will be greatly reduced. The cooling fans haven't been
installed yet, so activity on the repeater will be limited.
Please feel free to stop by the frequency and say hi and give us a
signal report.
Special thanks to Mark, N8UVQ for purchasing the 6-meter pre-amp and
helping Jim, KA3EBX with it's installation and all of the work on all
three repeaters this weekend.

Hi Jim,
How have you been? I certainly hope that you have been
well.
The repeater looks very nice. I have not been very
active on the amateur bands lately. I am now working
for PTTI or Pennsylvania Transformer Technologies at
Canonsburg, PA.
Yeah I'm back working as an electrical assrmbly
tester. I am involved in the testing of all phases of
manufacturing of large three phase and single phase
transformers that are use by the electrical utilities
for the generation of electricity.
It keeps me off the streets (sic) but most of all I
have really good hospitalization for the wife and I.
When I'm not working at PTTI I am working at home
doing repair of a more intresting nature. Currently I
am working on a KENWOOD 850B tha a fellow smoked and
did a really good job of it too.
Say hello to everyone there but can't say that I
really miss the place, ha ha. I am still bitter about
the way ADC screwed me out of my retirement fund. I
hope ole Bill Cadagan has a stroke (fatel) while he
chokes on a mouth full of steak, not that I dislike
him or anything like that.
Well take care Jim and keep up the nice work.

Greetings,
The repeater driver arrived on Friday (5/13/05). We connected it up
to a GE Master II Basestation +12VDC Power Supply, Bird wattmeter
and 100W load. We spent considerable time programming the repeater
driver's controller and testing out many of the features.
We verified that the output of the repeater was 60 Watts. Our next
step will be to mount the repeater driver into the rack and use some
temporary cables to connect the driver to the duplexer and test
antenna.
We'll run it like this at KA3EBX's residence until all of the
superflex cables have been made. At this point we'll test the entire
system before moving it back to the repeater site.
We've added a few more pictures of the actual equipment which makes
up the new repeater system.
The photographs may be found here:

Greetings,
Yesterday, we received the 100W PA for the repeater and we mounted it
in the rack.
Last week, we had a problem with UPS and the aluminum angle we
ordered. Apparently, the angle broke out from one end of the
cardboard tube while in route to us.
When the box was brought into the distribution center, an employee
from UPS noticed the damage to the box and reinforced the damaged end
with tape, not realizing that the box was now EMPTY and that's
exactly how we got it.
We had to file a claim with UPS who will pay the metal warehouse to
resend us our order.
If you want to see pictures of the new power amplifer, we've added
pictures here:
http://www.nb.net/~rikercdr/newsharc1.htm
We also purchased a Polyphaser lightning suppressor for the
transmission line.
*** SHARC-3 Update ***:
The call sign on the SHARC-3 Repeater (51.940 MHz)is now N3WX. The
repeater ID and courtesy tone has been reprogrammed. Currently,
there are (3) open commands on the repeater.
#0 = Touchtone (DTMF) Test
#9 = Force CW ID
#8 = Force Voice/Message ID
To test your radio's touchtone pad, while keying up, press #0 and
release the PTT switch. This will turn ON the DTMF test. Now key up
again and press any DTMF key and then release the PTT switch. The
repeater will send back the decoded key that you pressed in morse
code.
You can test other keys by following the same procedure: Press the
PTT switch, press a DTMF key and then release the PTT switch. You can
only enter in one tone at a time. After 20 seconds, if no tones are
entered, the controller will automatically turn the DTMF test OFF.
Please also note that all DTMF tones, except the digit "5" are muted
on the transmitter's audio output. The digit "5" is not, so that a
user can listen to their DTMF encoder deviation level on another
receiver for testing or level adjustment.
The above codes will be the same for the new SHARC-1 Repeater.
The PL tone frequency for ALL SHARC Repeaters is 131.8 Hz. ALL
repeaters will be normally set to tone OFF. If the repeater's PL is
turned ON, the repeater's CW ID will say "CALLSIGN/R SHARC P". If
the PL is OFF, the "P" will be excluded from the ID.
If the repeater is on battery back-up power, the repeater's CW ID
will say "CALLSIGN/R SHARC B". If the repeater is running from the
rectifier supply, the "B" will be excluded from the ID.

Greetings,
This should be a busy week for the new SHARC-1 Repeater. On Friday
(4/8) we received the bottom mounting plate for the batteries. We
also received a 50W load for the power splitter. The load has a -
30dBm sample port that will allow us to look at the driver power with
a spectrum analyzer.
This week we expect to receive our fan panels, battery mounting plate
brackets and repeater mounting brackets.
We also expect to receive the 100W Power amplifier and power splitter.
The plan is to run the 60W repeater into a power splitter,
terminating the unused port into a load. Each port will provide
around 30W. We'll then turn the driver output down from 60W to 50W
to satisfy the input requirements for the PA (25W).
From what I have been told, the driver can only be turned down so far
before putting out spurs, so this is why we are trying to keep the
driver power as high as possible. We went with a power divider,
because we couldn't locate a 60W, 3dB attenuator that was reasonably
priced. If the PA should fail, we can bypass the power divider and PA
and connect the driver directly to the antenna. The driver is a
mobile, 100W intermittant duty PA, turned down to 60W for continuous
duty operation.
We've created a webpage which will show pictures of the repeater in
progress. The link is as follows:

Greetings,
We went up to the .513 repeater site today and removed the duplexer
which was previously mounted vertically in the old rack.
After some consideration, we decided to mount it horizontally at the
very top of the new rack. Although the mounting brackets can be slid
forward or backward, ideally the brackets were set to be in the
middle of the duplexer to help equalize the weight in front and back.
The power amplifier will be mounted below the duplexer and the driver
below the PA.
One of the original reasons we didn't want to mount the duplexer at
the top was to avoid making the rack "top-heavy" but considering that
the power supply and 300 lbs of batteries will be mounted at the
bottom, it doesn't look like there's going to be a chance of it
tipping over.
One of the reasons we chose to put it at the top was because the
duplexer and tuning rods stick out very far and we didn't want to
take the chance of someone poking their eye out or getting gored when
working on the repeater. It will also help prevent someone from
accidently bumping into the tuning rods and possibly bending them.
With the duplexer at the top of the 7' rack, its well above most
people's heads.
If you would like to see a picture of how we mounted it, click the
link below:

We're still waiting for the repeater and PA to arrive. The PA should
arrive this week. More pictures to come.

Jim, if that repeater is a GE Mastr series mobile, be very careful when
turning the power down. They sometimes spur like crazy when you reduce
the power. You might want to use a matching section between the
repeater and amplifier as well.

Greetings,
We've purchased a new power amplifier for the new repeater. The new
repeater (driver) has an output of 100W, but it is derated (turned
down) to 60W for continuous duty operation.
We lose about 20W through the duplexer, so we can expect to get about
40W out of the duplexer to the antenna.
We have purchased a solid state power amplifier that is designed to
provide 100W out with 25W in. The amplifier is continuous duty,
convection cooled and designed for repeater use.
We plan to turn down the output of the repeater (driver) so that the
amplifier isn't overdriven. We'll probably set the driver level so
that we can get around 60 to 70 watts out of the duplexer, which was
around the same level of the original repeater. We going to run the
amplifier under 100W.
As mentioned before, we're going to take a few pictures of the new
repeater with a digital camera and post them on the club's website.
We hope everyone will help give us a signal report once its up and
running.

Last night we mounted the the +12VDC rectifier supply into the
telecom rack. We need to put an AC power plug on the end of the line
cord. We also mounted the AC outlet strip.
Our next step is to fabricate the fan panel, which will include (2)
+12VDC, 5" fans. We're also looking at installing a temperature
controller that will turn on/off the fans based upon the temperature
of the PA in the repeater.
We're still waiting on the repeater itself to arrive. We're hoping
to get everything on the air in April.

As we mentioned in a previous notice, we've purchased a new repeater
for the SHARC-1 Repeater (145.130 MHz). Some of the parts have
arrived. The repeater itself is being custom built for us.
We ordered a 7' Hoffman Network open frame rack which arrived
yesterday (3/28). Also arriving were various height, 19" black
panels which will be used to fabricate a DC fan panel and speaker
panel.
We have already fabricated the speaker panel which will be used to
monitor the repeater's receiver audio at the site.
The fan panel will house (2) +12VDC fans which will be used to cool
the repeater's heatsink.
We also purchased a lighted, rack mount (6) AC outlet strip which has
also arrived.
We would like to thank Ken Pollock, WB3JOB, for donating a rack
mount, rectifier supply that will be used to power the repeater. The
supply provides over/under voltage protection as well as meters to
monitor output voltage and current. What's really nice about this
supply is that it has battery backup. Ken has also donated batteries
that will be charged by the supply and will kick in should the AC
power fail at the site. This will keep the repeater on the air
regardless of power failures.
The repeater controller has CW & voice ID with autopatch/custom speed
dial numbers that can be programmed remotely.
We'll be taking pictures of the repeater as it is constructed and
post these pictures on the club's website.
We'll keep you informed on our progress.

Greetings,
Friday, will mark one week since we believe we cured the problem with
the SHARC-1 Repeater. We haven't heard any problems at all since.
Today, we purchased a GaASFET preamp for the repeater. The existing
pre-amp uses a MosFET and was manufactured in the 70's.
We hope to install the new preamp next week. We would appreciate if
anyone can check in and give us a test signal with location report so
we can determine if the new preamp is working correctly.
We'll keep you posted as to the progress. Yesterday morning, Ken,
WB3JOB checked into the repeater from the Summit in Uniontown. Ken
reported that the repeater was full scale there. Later that day, he
also checked in from Cranberry PA.
Thanks to everyone who helped provide techical assistance with the
repeater!

Greetings,
As many of you know, the SHARC-1 repeater (145.130 MHz in
Bridgeville) has had an intermittant problem for quite some time now
that has caused us at times to put the repeater on PL or turn the
repeater off. The problem seemed to arise when the temperature at
the site would drop in the late evening through the next morning
until temperatures increased. What seemed to be happening was that
the transmitter signal was getting back into the receiver and causing
a condition whereby the repeater would lock up and create an audio
squeal.
Over the last month we have been actively pursuing the cause of the
problem and have performed general maintenance on the repeater. The
following list descibes what has been done to the repeater over the
last month.
1. Removed repeater transmitter, cleaned all accumulated dirt & dust
from transmitter housing & heatsink cooling fan.
2. Replaced burned out transmitter "transmit" bulb with a bright
white LED.
3. Repaired cracked solder joint on 8072 final PA tube socket.
4. Relocated over-temperature sensor so that the transmitter rear RF
cover could be installed.
5. Added grounding stand-offs & fingerstock to the IPA board to
improve grounding.
6. Retuned x4 Multiplier, IPA and final RF PA stage.
7. Replaced Basestation Power Supply with the back-up supply so that
the main supply can be cleaned and inspected off-site.
8. Replaced the exciter cable between the receiver and transmitter
with a double shielded cable. Added SMA connection in between so
that transmitter & receiver can be easily taken from the rack for
easier servicing.
9. Retuned Exciter.
10. Replaced both coaxial cables running between the duplexer and the
transmitter / receiver with shorter, double shielded cables (believed
to be the major cause).
11. Removed several RF adapters in the transmitter & receiver path.
12. Installed front & rear RF shields to transmitter (these have
never been installed on the transmitter).
13 . Removed duplexer and bench checked using a Network Analyzer &
Spectrum Analyzer (Thanks Paul K. from Axcera).
14. Added quick disconnect connection between 110VAC and transmitter
cooling fan so that transmitter could be removed for easier servicing.
15. Added quick disconnect connection between transmitter over-
temperatire sensor and repeater controller so that transmitter could
be removed for easier servicing.
16. Calibrated transmitter output frequency.
As you can see, we've been pretty busy, but we're not finished yet.
We want to make the following additional changes:
1. Retune receiver.
2. Calibrate receiver frequency.
3. Replace existing 1970's pre-amp with a new GaAsFET preamp.
4. Install front & rear RF shields on receiver.
5. Replace existing antenna & hardline (Next Spring).
After retuning, the transmitter was putting out approximately 100
watts. We backed down the screen control to lower the output power
to 80 watts. This will help prolong the life of the 8072 tube. We
measured approximately 60W at the outputput of the duplexer. The
duplexer has -1.5 dB of insertion loss. The reflected power was
measured to be 0.2 watts, which correlates to a VSWR of 1.125:1. This
is very good!
If you get a chance, please try keying up the repeater and observe
the signal coming back to you. We would appreciate signal reports
which will help us determine our coverage area. You can tell if
you're getting into the repeater well, by hitting the # key on your
touch tone pad. This will tell the repeater to say the current
time. Please make sure you properly ID before doing this. Thanks to
Brian, KB3IFR who was our first contact on the machine since all of
the repairs have been made.
So far, the repeater has been working flawlessly and we hope to make
it work even better with the proposed changes to the receiver &
feedline.
Special thanks to George, KA3GIR, Ken, WB3JOB and Ken, WA3DIQ for
their technical assistance!
Please let us know how the repeater is working in your area. The
repeater will be "OFF" PL from now on..... hooray!

Thanks for the invite this Saturday, it would have been nice to see everyone. It is unfortunate that I won't be able to attend this Saturday since I have to complete testing and calibration on a fleet of low band equipment that is in dire need of my attendtion.
The Motorola remote base has been struck by lightning and has sustained some serious component failure, both on the modem port and the ac power I/P. The transient even got to the main R/T chassis, rather dissapointing for Motorola, their equipment isn't what it used to be, but that seems to be the trend......more bean counters & less worthwhile engineering.
So... how have you been doing??, ur health been good? I hope so. I've been doing really good, have been staying pretty active and of course I always manage to get involved in an Amateur project which is building an all soild state tranceiving system for 1296 MHz. Although I get interupted quite frequently it is comming along quite well. I have most of the modules done and have started ti make the interdigital filters (of which I need several) for the TX and RX paths.
The filters are actually fun to build, I have finished the first one it has seven active poles, it is fully tunable, it's 1dB bandwidth is 20 MHz, roof variation less than 0.8 dB, insertion loss 1.0 dB with an excellent skirt factor. I will build two more and they will have LO traps built in and they will be placed at the DBM's and one more filter to be placed between the RX preamps and 2nd rf amp and then I can start fitting everything into as small a cabinet as possible and harness it all together. I'm hopeing to come out of the main chassis at about 8 to 10 watts and then make an external 80+ watt power amp.
I will be using my FT-847 for the signal source at an IF of 432 MHz. My only concern here is that the 70 cm may be to large a mixing ratio for a 1296 output of the mixers but I believe that double balanced mixers will perform satisfactorily.
What have you been up to? Say hello to everyone for me .....73's JACK / K3DMY ._ ._.
