Status update: 08/26/2017

Dealing with Hurricane Harvey and its impact on South Texas.  The Texas Connection is connected to the Hurricane Net full time until the emergency is over.  Once the event is over, everything will resume regular operations.

 

Status update: 07/21/2017

The 441.625 repeater is sick...  The audio on the control board has decided to flake out.  I am searching for a replacement as we speak...

 

Status update: 07/12/2017

The 441.300 net repeater is back up!  I found a guy in Arizona who will repair the final amplifier stage in R1225 repeaters for a flat fee.  I sent him a couple of units to try out his services and received them back in short order.  I replaced the dead radio with a repaired unit and we are back in business!  All net operations shall resume as per normal.

 

Status update: 07/03/2017

A lot of things have happened...  Not all of them good!

The cross band repeater croaked, and I do mean croaked!  It smells like burnt capacitors...  (And death...)  It gave up the ghost, finally, after being in use (and never being turned off!)  for many years, without a rest.  I just couldn't revive it once more...  It will be missed and given a full military funeral with honors before it goes into the dumpster, never to return.  It got replaced my an AllStar driven cross band repeater built out of an old pair of Motorola Maxtrac radios.  It is now an "agile cross band repeater" connected to my little network here at home - that I can control remotely!  It will soldier on for years to come now, we hope!  Now I can resume being able to use my HT to talk to the guys on the Brenham repeaters while on my porch, grilling steaks...

The Net Node Repeater (441.300) decided to join its buddy in the great beyond!  After many years, the finals gave up after the guys on the Insomniac net kept it going into the wee hours of the morning, rag chewing.  The guys on the Alaska Morning Net didn't help it either.  Soon, the 25w radio will be swapped out for a 10w spare radio I had on the shelf.  One of these days, when I find a new 45w radio, I will put that in, when I find one on eBay for cheap.

We swapped out the aging 25w Maxtrac based 70cm repeater (441.625) we have been running and upgraded to a 100w Quantar beast set to 80w.  It should run forever, I am told.  But I have noticed the difference immediately.  I can talk on it all the way in to 99 in Houston, It's a wee bit better than it used to be!

We swapped out the aging 25w Maxtrac based 2m repeater running into a 100w amplifier with a new 25w Quantar beast set to 20w.  It should run forever, I am told.  Running into the same old Henry 100w amplifier.  It seems to be more sensitive now...

The old 900 MHz 100w Quantar got a new final amplifier module and is now back up and running at full steam.  The old one got too hot and gave up.

Now that I am running 3 big, fat, hairy, fire breathing, Quantars, (and some pretty hefty power supplies to run the amplifiers!)  I have discovered that ONE 15amp circuit is NOT enough!  (LOL) I kept popping the circuit breakers!  (Giving my UPS's a REAL workout!)  So I had to rearrange things and split things up that were plugged into the wall, now they are spread across multiple circuits to spread the load...  NOW when the fire breathing Quantars key up, the lights in the repeater hut no longer momentarily dim...

We had to install a larger AC unit in the repeater hut!  The little 4500 BTU window unit just wasn't cutting the mustard with summer coming along.  Now that we have a 8000 BTU unit in the window, it stays nice and cool inside, even when it is over 100 degrees outside!

Yes, my light bill IS a nightmare every time I open it!

The new Independence site has now come fully online!  With a 100w UHF quantar.  It covers most of the county pretty well!

The Industry site got upgraded from a 10w UHF repeater to a 45w UHF repeater.  The KF5KXL repeater now has much better range!

We added "AutoSky" to all of our repeaters that announce the time of day, the weather and the temperature at the top of the hour.  It will also automagically announce weather alerts!  It downloads weather info from the NWS every 4 minutes.  If an advisory or warning pops up, all of our repeaters will nwo let you know about it!  Tropical storm Cindy was its first trial by fire and it came through with flying colors...

We added recorded announcements at the quarters of the hour to all of our repeaters.  Now that we figured out HOW to do it, I can add club announcements to the mix in the future.  I see this as something that will be downright handy in the future.  With text to speech applications on the web, I can make my repeaters say anything I want, at the exact times that I specify.

We setup a new website!  Checkout www.thetexasconnection.net for more info!

The Washington County Amateur Radio Club's website now resides on our servers!  After a lot of struggle, the web site has been ported over and is now happily running on our web servers - that are a HELL of a lot faster than their old web server!  I am humbled that they have entrusted me with their data and I appreciate their trust.

We have upgraded our ability to remotely control repeaters connected to the world wide network.  Now with new management consoles, it is easier than ever to control our repeaters and other repeaters connected to the network, no matter if they are here or clear across the country!

Checkout the new monitoring console for yourself...

We upgraded some of our local area network components to improve throughput and reliability.  My farm network is more complicated than some small business networks!  I am literally running out IP addresses...  That's when you know you have a "problem".  I AM a computer geek...

We upgraded, replaced and installed new cameras overlooking the farm from the main repeater tower.  One of them is a new pan/tilt/zoom camera that can easily see in the dark!  It's a shame Weather Underground changed their software so our cameras will no longer feed them images every minute of every day...  But I have one hell of a view from the top of the tower now!

We recently went through a MAJOR project of upgrading our computers to control our repeaters.  The big old PC needed to be retired - it was over 10 years old.  We now have four stacked Raspberry Pi's arranged in a single rack mount enclosure with all of the URI's that hook up to everything in the repeater hut.  We also installed a couple of new RasPi's to control all the others and the new cross band repeater.  This does away with the ONE big PC running Linux that had gotten so old that it had started flaking out and doing weird things, intermittenly.  The little capacitors just aren't what they used to be, and it was affecting network operations - so it had to go!  Now that all the RasPi's are running things, things have settled down and become MUCH more reliable...  May the old eMachines PC rest in pieces...

Now we have 8 RasPi's controlling everything under Linux...  Soon to be 10!  (Yes I AM a computer geek!)

That's all I can remember for now...  More changes will come, you can count on it!  As I upgrade things little by little... 

Status update: 05/21/2017

Everything is all back up and working like it should!

Status update: 05/10/2017

Almost all of our repeaters are all back up! I had a problem with 441.625 and need to swap out radios and the Xband repeater died.  But everything else is back up and running!  The 145.15 repeater and the 441.300 repeater should work better than ever now that the antennas are up at 100 ft.

 

Status update: 05/07/2017

Our repeaters are all down at the moment due to the tower and antennas being worked on.  We should be back on-line before the end of the week!  The networked system is still up and running, only the RF portion of the system is off the air at this time.

The tower is being raised to its full height and the system should perform better than ever.

Please be patient with us as we upgrade our facilities.

Status update: 04/25/2017

We found a set of 1.2GHz duplexer cans on eBay!  Now we are feverishly hunting for a suitable antenna to make the 1.2 GHz repeater work!

Several of the local UHF repeaters have changed frequencies to get them off of the "Backyard Repeater" frequencies and onto Coordinated protected frequency pairs.  Please notice that some of them are now on PL123.0!  Please welcome Pam KF5KXL in Industry and the Prairie Hill / Rocky Hill Fire Department repeaters to the mix!

Many thanks to Fred W0FCM for all of his help getting all this stuff working like a champ and James KB5RIR for hosting our ARES hub up in Dallas!

Now actively looking for hams to host additional VHF/UHF LINKED repeater sites in or around the Lake Somerville, Navasota, Waller and Bryan/College station areas. We have the gear, we just need sites to put them at that have full time Internet connections available.

Status update: 03/31/2017

We found an Icom IC-RP-1220 10w 1.2 GHz repeater on eBay!  Now we are feverishly hunting for a set of duplexer cans and a suitable antenna to make it all work!

Status update: 03/21/2017

We changed our 6m repeater setup - we changed from 103.5PL over to DCS 131.  This is Digital Coded Squelch.  Most modern radios have it, although most hams don't use it.  It is on the input and output as DCS 131.  For scanner listeners this won't be an issue, they just leave the tone off the frequency entry.  We made this change to eradicate the howling interference that sometimes comes and goes sporadically and without warning and hangs the system up.  It also makes it impossible to leave our 6m machine in transceive mode on the WIN system!  We are testing this new change and we will see how it goes.  It should solve the interference problem.  Please send any commments or signal reports to N5MBM.

The Quantar 900 MHZ repeater had a PA failure, we repaired it and it is back online as of today at full power!

Status update: 02/25/2017

We installed a new repeater at Kruse Village in Brenham, TX. It is on 441.325 + PL103.5 and it is working quite well!  Range has been measured at about 15 miles.  Not bad for a 5 watt repeater with an antenna mounted at 20 ft. above the ground!  We also revived the W5TZ repeater down in Kenney, TX. and got him back on the air with a whole new repeater.  Both are connected to the Chappell Hill HUB 24/7/365 to facilitate county wide communications.  In other good news, we purchased a new spectrum analyzer with a tracking generator in it!  It makes tuning cavities and filters an absolute breeze...

Status update: 08/21/2016

We revived the Scanner server from a Microsoft induced coma and added the N5MBM repeater system live audio feed to a reflector on RadioReference.com and Broadcastify.com.  Now you can listen to the N5MBM repeater system via a web browser window.  It is "Almost live" as there is a built in 20-45 second delay due to it all being digitized, sent across the internet and processed before being sent to you.  But we have our Amateur radio streaming audio back up now!

Status update: 07/13/2016

We just replaced our 900 MHz repeater with a Motorola Quantar unit!  Now running 75w on a 100 system designed like a tank.  It should give us many years of service!  Along with a new repeater came a new Wacom WP-687-3943 900 MHz Diplexer converted into a duplexer set up for the ham bands too!  Our coverage just got tripled on 900 MHz...

Status update: 02/21/2016

Power increase project complete: We recently carefully increased the power on all systems.  The 6m repeater is now running 100w into the duplexers with an amplifier.  The 2m repeater is now running 100w into the duplexers with an amplifier.  The 220 repeater is now running 25w into the duplexers.  The 440 repeater is now running 45w into the duplexers.  Everything seems to be running clean and all my interference issues have been dealt with.  I am still hunting for amplifiers for 220 and 440 MHz.

The 6m repeater is now being tested by being connected to the WIN system 24 hours a day.  The amplifier is running cool even with a heavy traffic load during certain times of the day.  The 441.300 repeater has now been dedicated to our net schedule, thus leaving the rest of the system open for normal day to day local communications.  This arrangement allows people the chance to talk all over the world on 6m and participate on worldwide nets on 440 AND be able to talk privately, locally without talking to the whole world.

Our 2m/70cm cross band link into Brenham is slowly dying.  Duties are being done by an OLD 1980's vintage Icom dual band mobile rig with cross band repeat built in.  It is now showing its age and becoming deaf and incredibly slow on PL detect.  Probably due to old caps that just can't hold together anymore.  It will soon be replaced by a cross band Motorola radio setup with the same PL tones and also be frequency agile to keep our systems flexibility intact allowing us to quickly change frequencies to link into various repeater systems outside HT range from the Chappell Hill metroplex area.

 

Status update: 12/25/2015

The transition to an ALL Asterisk controller based system is now complete.  The Arcom has been retired to duty on our 220 repeater only.  The internet connection has been upgraded and is now more reliable.  Lightning protection has been installed.  The 900 MHz repeater is now operational!  New double shielded cables have been swapped out making 98% of our interference issues disappear.  And Santa Claus brought me a new 6m/2m HT and a new tower climbing harness!

Merry Christmas and a Happy New Year!

Status update: 12/13/2015

We are in the middle of upgrading and migrating away from the Arcom RC210 controller to a Asterisk based Linux machine for a multi-port controller to tie all the different repeaters together.  This will add much more flexibility in how we do things and how the world wide web can connect to our repeaters and USE them.  Many many thanks to W0FCM for helping me make this a reality!  We have added AllStar and Echolink to our system and we are in the testing phase.  We have also RE-tuned our 70cm duplexers giving us more range.  We have made some small upgrades recently and will be upgrading the system even more in the near future with upgraded power supplies and MORE POWER!  :)

Status update: 11/04/2015

The tower is finished (to 50 ft. at the present time) and all ports are now active!  (The 100 ft. tower extension project is in the works!)

Status update: 09/03/2015

We are now officially coordinated!  The new 6m repeater is now online!  Antennas have been upgraded, equipment moved and we are prepping for the big tower project.

Status update: 07/04/2015

All repeaters and nodes that should be operational, ARE now operational!  Everything is nominal and back on the air!

STATUS UPDATE: 5/29/2015

As of May 2015 a VERY direct lightning strike has taken out our ATV repeater, the VHF, UHF and cross band repeaters and all the associated feed lines, antennas and power supplies.  We are diligently trying to get things back up and on the air, but it will take some time...

 

STATUS UPDATE: 4/11/2015

We have been moving and renovating our facilities.  New power feeds, new UPS's, new racks and most importantly, MORE ROOM!  We have been busy adding features!  We have recently upgraded our routers, upgraded our network gear and upgraded multiple servers to better serve nice people like YOU.  Please be patient as some options may not work every time you try them.  We are working on several different facets of our network, servers and radio equipment all  at the same time and chasing bugs down has been like an evil game of whack-a-mole!
