Not the people’s FCC?

There’s a lot of interesting information in this article. Some is speculation but keeping alert seems like the smart move here.

Can’t contact your family in Puerto Rico? Here’s what to do.

If you have not been able to contact your loved one in Puerto Rico after Hurricane Maria, the territory’s Federal Affairs Administration is asking people to do the following:

▪  Try the American Red Cross "Search for Loved Ones" page at:
Contact the island’s disaster relief team by e-mailing . Include your contact information and as many details about your family member or friend as possible. Because of high volume only send one email unless the status of your loved one has changed. 

▪  Call the Washington D.C. office at 202-800-3133 or 202-778-0710. Getting through may be difficult due to backed up phone lines.

▪   Radio station WKAQ, which was nearly destroyed, can be listened to online.

County, Ham Radio Operators Hash out Rules for Emergency Situations

This is an interesting article about the Wichita County Hams working out how they will handle their emergency weather nets. The wording in this write up is a little ambiguous but they have decided to have "controlled nets" rather than "closed nets. However, later in the article they explain that 

"if  unofficial storm chasers are disrupting official business, then law enforcement can be called in to deal with the situation."

I'm not sure what form of disrupting traffic they are experiencing, but that sounds a lot like a closed net. I imagine that some people get annoyed with rain reports from hams that are miles away from a tornado, but discouraging reports seem to be a fast path to discouraging people. Locally, we can use all the help we can get. Judging from the wording of the policy, they have a need as well.

442.300 Repeater Update

It has been a while since the last post on Texas Ham Radio, so I thought an update on the 442.3 repeater would be a good idea.

The current configuration is the Yaesu Fusion repeater running on low power into a 35w RCA TacTec Amplifier into the Celwave duplexers. Directly after the duplexers is 11 feet of  RG-214 coax. This is Mil-C-17 Spec, double shielded with silver braid and solid silver center coax. Expensive at almost $5 per foot, but provided the least amount of rejected power over going directly to the 1/2" heliax. After the RG-214 is an MFJ Lightning arrestor. This will be replaced with a PolyPhaser soon. After the arrestor is the 1/2" heliax (170' coiled up) that runs to the DB-420b on top of a 55' crank up tower.

In the current configuration the repeater output is 5w into the amp and 30w out at the heliax. A loss of 5w seems pretty good with all the UHF connectors still in use. 

I have acquired 100' of Rohn 45 that I will be installing to replace the 55' crank up.  Currently, the range of the repeater is very limited. The extra height should add some much needed distance to the repeater coverage area.

The repeater is running in full auto mode allowing digital and analog communications. Several other repeaters are in the surrounding counties and are running AMS/FIX, which takes all signals and converts them to analog on the repeater output. Once more people get Fusion radios, I expect they will go full AMS as well.

If you are traveling through Henderson, tune in and give us a shout.

We're Amateurs, but that doesn't mean we shouldn't be professional.

I finally got around to putting my 20m double bazooka back up after we used it for Field Day. Needless to say, it's been a while since I chased DX. So once the antenna was up, I had to spin the knob a while. Right away I saw a Ghana station on the DX Cluster and went right there.

I was appalled at the stations tuning up, using partial call signs, calling when the DX station didn't call them and calling while another station was talking to the DX station.  It made me wonder if they took the same exam I did to get my ticket? I could have sworn that was covered in the material.

 In the end, I left the circus and snagged S79C running a DXpedition in Seychelles instead. 

So, here's the link for the DX Code of Conduct. Please pass this along so that others will remember that just because they call us Amateurs, doesn't mean that we shouldn't be professional.

DX Code Of Conduct

  • I will listen, and listen, and then listen again before calling.
  • I will only call if I can copy the DX station properly.
  • I will not trust the DX cluster and will be sure of the DX station's call sign before calling.
  • I will not interfere with the DX station nor anyone calling and will never tune up on the DX frequency or in the QSX slot.
  • I will wait for the DX station to end a contact before I call.
  • I will always send my full call sign.
  • I will call and then listen for a reasonable interval. I will not call continuously.
  • I will not transmit when the DX operator calls another call sign, not mine.
  • I will not transmit when the DX operator queries a call sign not like mine.
  • I will not transmit when the DX station requests geographic areas other than mine.
  • When the DX operator calls me, I will not repeat my call sign unless I think he has copied it incorrectly.
  • I will be thankful if and when I do make a contact.
  • I will respect my fellow hams and conduct myself so as to earn their respect.
