Just a quick update.. KC 6 meter repeater project... JUNE 14, 2014

The 6 meter 52.97 Mhz repeater is now broadcasting in a test mode...

its N0CRD ID (cw and voice) and short messages every 15 minutes on

the 52.97 Mhz with a 91.5 PL tone. Currently we are running about

75 watts out into a J-pole up about 30 ft in the air.

Location.. Olathe, KS.

We have installed Node # 1 in Shawnee, KS and are currently building / tweaking link antennas.

The 51.27 input (with 91.5 PL tone) will be sporadically available

in the next few weeks...

_______________________________________________________________________________

The 10 Meter repeater Cross Link has been nixed due to concerns of possible improper license issues.

_________________________________________________________________
We have not, to date, determined where the permanent receive site will be, and would be 
open to suggestions. A little height (roof top) and a Kansas City metro / 
Overland Park / Shawnee / Olathe or other location would be best. 
 Alternatively, If you know where we might have a small roof top area, we would not need the tower. 
We would need it to be equipped with 110 v outlet and a place to set a 6 meter J-Pole along 
with a small 440 Mghz 5 element beam.  
Please give us a shout as we are currently / seriously looking!
 For this piece of the puzzle; the sooner the better!
All in all, the project is still coming together nicely! 
Thanks to the generosity of our community!

June 21, 2014 update
I am betting there are those that are wondering if this project
will ever get done! Life and work has a way of demanding your time.. 
However, the project is very much alive.
We have our first 6 meter receive link positioned in Shawnee, KS.
 Currently installing newer coax and beam link antennas to increase reliability ect. .

K0KN (Kyle) was kind enough to respond to our request for some
pre-wired RJ (mike) connectors and made life a whole lot easier 
in finishing the link modules. Currently he is helping to convert
 a pair of Kenwood radios for the project.

The Temporary central Link receive location with the voter unit is in Olathe. It is operational, waiting for the Shawnee link to come on line. It is test mode.. announcing every 15 minutes on weekends and some week days. Depending on our work / and mods we are doing.

Out of necessity, 4 each 8 element (12 db gain) Quagi beams were manufactured from scratch this last week at a material cost of under $10 each and about 2.5 hours per unit. The performance of these antennas is outstanding and will be used for all the 70 cm control links along with runs of Beldon 9587 (75 ohm) low loss coax. The low SWR and match was so good it required no further matching.

It has become obvious however, That since we have somehow lost the downtown Commercial bank location for our Central point, In order to cover the Kansas City metro and outlying areas ( 50 to 100 + miles) we will have to either increase our 6 meter power output to about 300 watts plus... AND / OR find a much more elevated location for the Central control receive / 6 meter output. Any locations suggestions or equipment donations are now open for consideration..

The Central unit does not have to be in downtown Kansas City.. Currently it is in Olathe it does pretty well. Actually, if we were elevated 100 plus feet, I believe we would do more than OK Add a little more power and all would be good.

If anyone out in Larry's list land happens to have an extra VHF 300 watt or better PA they are not using.. Or even an old tube style 300 watt + 6 meter transmitter, PA or repeater shoved back in a corner somewhere.. We would be interested.. There were many old combination PAs built for 10 meters and 6 meters. We are not picky.. We might be able to convert a 10 meter unit to work 6 meters.

Actually on Ebay there might be a newer / better solutions for increasing the power.. But That requires money we don't have. 1. ME750 6 Meter RF deck - 2x GI7BT's installed - NEW OLD STOCK! 2. 48-73 MHz 300 WATTS 4 METER PROFESSIONAL PALLET RF POWER AMPLIFIER NEW MODEL Both choices would require more Power supply and control modules ect.. More construction. It would be better to find an older, out of service, self contained unit..

Currently we hit Independence, MO (I am told) with an s4 reading.. Corporate Woods S6 - 7, Shawnee 20db over, Desoto 20 db over, Spring Hill s7 to 9, And I have no idea what type of antennas / rigs these reports are coming from. We are good for about 15 to 30 spotty miles.. now. With a correct vertical receive antenna at these remote locations, I believe there would be much signal improvement. at these locations. Of course, to best receive the 6 meter 52.97 Mhz signal it is always good to have a vertical polarized antenna tuned to the 6 meter center frequency you are trying to receive. (like the inexpensive J-pole).

By the way, anyone wanting a home brew j-pole built for them, I will be happy to manufacture one for them for a cost of about $25 FOB my place.. That would be a break even cost considering wear on tools etc. The antenna itself would be about 15 ft tall but very slender (easily handled) and made of electrical conduits. @ 52.97 mHZ about a 1.5 to 1 swr. or less. Something you could easily put up beside your residence. I put mine on top of my HF beam mast. Works great! Home brew J-pole Equipped with an SO 239 coax socket for your PL259 connector / coax and Ready to mount on your 1 1/4 inch pole or other. Antennas would be built in batch lots.

We hope to have full repeater function with the first link up before the end of JUNE. We hope! Any comments, Suggestions or other is always welcomed!

July 20, 2014 update

The KC 92.7 / 91.27 (91.5 pl)  6 meter transmitter / repeater system seems to work well.  It is an OPEN repeater for anyone to use!
Announcements every 15 minutes for your identifying pleasure..
The repeater is in full operation at this time. Voting system seems to function correctly and waiting on more remote nodes to be installed.

We need information from the Amateur radio community once again to measure the effectiveness of the KC 6 meter repeater. If the Amateur radio community who have the ability to transmit to the 6 meter FM repeater, could take a moment, and try to communicate or bring up the machine and share your results. it would be most helpful.
If you bring it up, it will give you a courtesy beep and cw id.

The questions about your experience with the 52.97 repeater we are wanting answered are as follows:

Your call sign....................
Your location?...................
Your transmit power?...............
Your antenna  (mobile, base, vertical horizontal or other)........................
Our 52.97 signal report? ..................

_______________________________________________________________________


We have had some trials at this end:  Bad coax being replaced
and now we are finding out the true colors of our 30 year old radios.
Decided to test all links and found the Maxtrac (link 4 radio) receive was deaf.  Replacing it.

The node 3 pair wasn't even programmed for the link #3 and apparently couldn't be, (working on that).

1.  The Node 1 central receive - Tested, installed and up.  Remote receive installed at Shawnee.
2.  The Node 2 central receive tested, working and waiting on remote node install
3.  The Node 3  central receive - Waiting for a new or repaired pair of radios.  (Old Motorola sm50s not programmed correctly)
4.  The Node 4  central receive - Deaf Motorola uhf maxtrac needs replaced, waiting on remote node install.
5.  The Node 5 central receive tested, Up and waiting for remote node install.

The Shawnee location was equipped with remote node 1 equipment.
The node remote is tested, installed and working well.

If you have the ability to transmit and receive on 6 meters FM (repeater input. 51.27 with 91.5 pl and receive on 52.97 FM  You probably could / would bring up the Shawnee machine.

The Shawnee remote should have an effective receive radius of about 25 to 30 miles depending on your elevation and power. I bring it up with 30 watts or less with my mobile rig.

The 52.97 transmitter (70 watts) in Olathe should also be good for about 25 to 30 miles or more, and you should have no trouble if you have a well matched vertical receive antenna like a j-pole or vertical dipole.
Of course if you are further away.. and have a horizontal 6 meter beam.. go for it!

In the beginning when promised a central site in down town KC.. The design was to surround the central location..
However, that site was withdrawn at Christmas.. 2013.  So a new direction was elected..
Simply install as many remote nodes as possible.. starting with the closest remote node location...
Slowly add more remote receive nodes...
Then  increase the transmit power to +/- 300 watts.
300 watts transmit from Olathe should give good coverage to a 50- 75 mile transmit radius
The remote receive nodes in concert with the voting technology we have should work great!

The Shawnee site sits at 16.2 miles from central receive. and works well from my mobile (using only 30 watts and less).
Of course the closer in to Shawnee you are.. the less power it will take to bring the repeater up..
In a 20 to 30 mile radius of Shawnee (maybe more??)  I would think 30 watts would work. It does for me.

The proposed Independence, MO site is 47.2 miles from Olathe.  When in the beginning it would have been only 15 to 20 miles..
It was going to be the first remote node. but now we will need to have more power (70 cm / 100 watts?) on our link system
or a change in link method. (ie via internet?).

The Raytown site is again about 25 miles from Olathe.. Still can work waiting on a tower to be completed.

The Osawatomie site is about 30.3 miles. Still can work.  Needs more testing on link receive, etc.  Maybe next?

Lees Summit is about 29 miles. Still can work.  Waiting on a location.

A remote site in Lawrence, Ks would be viable.  Need location for the remote node.

To date, if we were to purchase all the equipment (in a used state) currently ready for use and charge for the amount of hours all have volunteered, I have estimated the project would have already expended well over $7500 to 10,000.

Unbelievable..

Yet, we are on the verge of having a metro wide system capable of cross banding and being positioned to offer multiple Amateur radio services to the community for very little dollars (compared to real cost) but a lot of volunteered equipment / man hours.

We have gone too far to stop now!

July  12, 2014 Update!______________________________________

For the past few weeks the 6 Meter repeater has actually been on the air... off and on.

Receive Node Number 1 has been established in the Shawnee Kansas area.
52.97 out with 51.27 input PL 91.5...  announcements every 15 minutes.
Still getting the wrinkles out!

From this day forward we will leave the machine on full time (with exception of mods and repairs
and a possible move to a new central location)..
Please note the 6 meter system is a vertical polarized antenna transmission.  70 watts at 40 ft.
So a vertical J-Pole will do great for your local KC (Shawnee node 1 area)  6 meter contacts.

We are still dealing with radio receive sensitivity issues, However, the system is working as advertised!
The voting unit is appearing to be working correctly.
Because of the success we have with the Shawnee location..
Our plans are to set two more Receive nodes around the KC Metro in the very near future.

85 % of All the KC 6 Meter project equipment we have..
has  been donated / modified and most is over 20 years old.
That being said .. please understand we are still gleaning equipment,
solving operation problems and planning for success.
All this balanced with work and home life.  Family always comes first!

We are not complaining..
We are rejoicing for those who have shared used radios, power supplies, coax and antenna, poles and all.
Not to mention those who have shared their time, skills and willing to donate home space.
I tell you this type of friendship and sharing holds up and waves the true flag and spirit of Ham Radio.

While it has taken a lot of patience, testing and modification.. (months of it)
We and the 6 meter repeater project participants are on the final stretch.

What we are doing is merely demonstrating to all..
If you have the will to learn, put your hands to use..  and execute on your idea..
you can make something out of most anything.. sometimes out of almost nothing!:-))
In our case the transceivers are old and generally discarded 400 and 50 MHz equipment.
Old Coax and Hard Line coupled with handmade clamps, supports and
antennas.  Some of which you don't know it is faulty till you put it in service!

Because of a shortage of old commercial antennas for our project..
We decided to try to build Good effective Antennas..  to fill the void.
And according to many ARRL handbooks You can do just that. So we did just that..

We have yagi beams antennas demonstrating 15 db gain..
manufactured out of #9 clothes line wire, 3/4 " wood and #12 copper house wire ( Our 400 MHz Qagi beams.)

Our 6 meter (3db  gain) J-Poles out of your kids old Swing set legs..
and cheap conduit / chain link top rails from Home Depot!
We are going to try to build some co-linear antennas that demonstrate 9 to 15 db
out of RG8 (not foam fill but hard fill coax) per ARRL handbook instructions.
This KC 6 meter project process has not come without multiple challenges.
Kinda like life.
It is how you meet those challenges... is what separates success from failure.
Having the patience to examine, determine the best course of action and then execute.
Not to get in a hurry or rush. and to expect more challenges.

For me.. It is truly a fun project that has created new friendships, acquaintances and increased my knowledge! _______________________________________________________________________________________________________

Jan 28, 2014..      What brought about this big project??

What was absent and needed in the KC area was for a public service, area wide  Kansas City 6 meter public safety communication system... for the Amateur Radio Community.  To be used as back up or primary use. This project is not just another simple radio repeater system, But one in which there will be a RF 50 MGHz receiver in every major surrounding communities (up to 10 each nodes planned at this time) surrounding KC, MO.

What this project amounts to is finding volunteers, locations and operators needed for establishing 10 each geographic node locations. The general idea of the system was to have one central voting / transmit site, with ten each remote site receivers.

Needed to even start and complete this project was to have donated or built...30 each transceivers with all the parts (cabinets, screws / hardware), electrical), 21 lengths of coax with connectors, 20 each UHF antennas, 11 each VHF 6 meter "J-Beam" antennas, 11 each "586" computers complete with control software installed and programmed for Node control / station ID on each node, 1 each central computer control, Internet interface for all locations, 2 each (5 station) voter machines and 11 each low ripple (professional) power supplies.

And of course finding the expert volunteer labor to program and electronically interface all the radios, install and operate all the antennas and tower necessities. Not to leave out finding the volunteer hours to monitor and administrate each node. I have in a very big way, also donating hours to build, wire and fine tune each node, set up / program each 586 computer along with interfacing the central control and voting system site.

The idea is each Node receiver will then relay back from low powered 6 meter transceivers(via linking 70 centimeter radios) to a central Transmitter site . Each of the incoming node signals will then be processed by commercial built voting machines.  With the strongest / signal to noise ratio winning the vote. Then that audio being re-transmitted to all the area... via a 100 watt or higher power, using the transmitter frequency of 52.97 MGHZ .

The project after 7 months is now 75 % complete!  Come Spring and warm weather.. the first 5 each nodes will be installed and brought into service!

The idea is to allow very low to medium powered 6 meter (50 mghz) Amateur Radios to access the area wide (5000 member strong) Amateur radio community. Hopefully to use for public service and every day communication. A challenge that has actually introduced me to newer technologies, created new friendships and kept me very active and alert.

Life is still interesting and fun!

More info on the project and monthly updates will be available …

We are Volunteers

E-mail Print PDF

The  KC 6 Meter Project Core Team and Working Group members are volunteer developers, designers, administrators and managers who have worked together to take the KC 6 Meter Project to new heights in its relatively short life. The KC 6 Meter Project has some wonderfully talented people taking Open Source concepts and old used wide band radios to the forefront of amateur radio standards. The KC 6 Meter Project is a major leap forward using proven concepts used by city / county governments in communicating with low powered mobiles (in not so well covered areas) .. and represents the most exciting KC 6 Meter Project in the KC area.  And if it were not for the generosity of all the donors....  donations of old radios, antenna materials, power supplies, Node locations.. This project would not be happening!  Most important are the folks who have been generous with there time  and labor in their helping with guidance,  programming radios, setting up computers and many task too numerous to mention!

It is a Grand experiment still unfolding!  Keep your fingers crossed.

KC 6 Meter Project makes it easy to launch a a multipurpose Amateur Radio project.. like Low powered 6 meter reception or experimental projects like "MESH". Whether you want a single site or you are building a large online community, The  KC 6 Meter Project hopefully will establish a way for you to make new friends, deploy a new project in short time and add maybe allow extra functionality as you need it.
