Here is Steel City big plans for summer. We are going to need several work parties to get all the work done, but to get you excited about the antenna improvements at the club house here are some of the details for the new HF antennas. The Mosley antenna will be mounted on the replacement tower to the right of the club house. And the Hex Beam antenna is going to be mounted on the far tower down by the cell tower. The club house will now go from 2 HF beam antenna’s to 4 beam HF antenna’s with two of the beam being able to do 40 meters. Combine with our HyTower vertical we will have some major power on the HF bands.
Mosley PRO-67-C-3 Transmits on the follow bands 10, 12, 15, 17, 20, 30, 40 Meter antenna with 3 Elements on 12, 15, 17, 20 , 40 meters and 4 Elements on 10 meters, and it has a rotatable dipole on 30 meters. With a 3 inch OD Heavy Wall Boom
One antenna with actual resonant elements, 4 elements on 10, 3 elements on 12, 3 elements on 15, 3 elements on 17, 3 elements on 20, 1 element on 30 Meters, and
3 elements on 40 Meters.

DX Engineering HEXX Beam Antenna
DX Engineering Mark 2 HEXX Beam Antennas offer gain and front-to-back performance that will exceed your expectations! Their unique shape is much smaller, better balanced, and has been reported to receive less noise than typical beams. Even at 22 feet across and 4 feet tall, their turning radius is less than a two element 20 meter Yagi, while offering several enhanced operating characteristics. They handle well over legal limit power on all five bands, so there is no power restriction as on competing antennas. DX Engineering HEXX Beams are very efficient, with full length elements and no lossy coils or traps, requiring no matching network so they are ready for a single 50 ohm coax feed at the top of the center post, as recommended by the engineer. They are light, easy-to-handle antennas that can be rotated with a light duty rotator, and they perform really well–even when mounted in the clear only 20 to 30 ft. above the ground.
Beam Antenna Gain:5.3 dBi
The 12 meter band is one of the three WARC bands. The 12 meters (24.890–24.990 MHz) were named after the World Administrative Radio Conference, which in 1979 created a worldwide allocation of these bands for amateur use. The bands were opened for use in the early 1980s. Due to their relatively small bandwidth of 100 kHz or less, there is a gentlemen’s agreement that the WARC bands may not be used for general contesting.
Very heavily influenced by the sunspot cycle. At the bottom of the cycle it is suitable only for very short distance groundwave communications only, for long periods of time. At the peak of the cycle it is capable of communications over thousands of miles with a minimum of equipment. Another nice mobile band when conditions are right.

Here are some of the nets I have found on the web that can be found on the Yaesu WiresX network. Which you can now connect to on the Steel City 444.45 Mhz UHF repeater. Just connect to the room number by pressing the pound symbol before and after the room number. For example #21080# then to disconnect press the star key *

We are currently testing our WireX connection to the Internet on our UHF repeater. WireX is a way to inter connection radio to other radios/repeater around the whole world. Each station or repeater has a User ID and a Room ID. By connecting to the User ID let one user connect to the station, whereas connecting to the Room ID let you connect to that person/club chat room where multiple users can have a voice chat with many other users.
The Steel City UHF repeater has a User ID of 33352 and its Room ID is 43352. You can find other station ID by clicking on the User List link below. This will list every other user id from around the world. Also listed there is their Room ID which lets you have a group chat via that station.
To connect to another station or room is first find their user ID or Room ID number it is an 5 digital number. For example the popular chat room America Link room ID is 21080 so using your mobile or HT on our UHF 444.45 Mhz repeater frequence you would DTMF the follow code #21080# which would let you connect to the room. At this point whatever you say to go though our repeater and come out to every other user that is also signed into the America Link chat room. When your done chatting with the other users you disconnect you just DTMF the “*” star key.

Final testing is now taking place! Karl KA3VXJ and myself have been working hard on getting a computer to load the WireX software and getting it hooked up to the 440 machine. It is working so far in analog mode but you can now connect to other stations and rooms. Our first contact was with a guy in Portland, OR not to bad for UHF FM. We listen and got to ask some questions about WireX on the Saturday night net on the American Link room which is on Saturday nights at 9 pm.
So if you want to try it out the Steel City node number is: 33352 and like I said we are still working on getting some bugs worked out. Some of the items are, getting the digital side working.. And to find a permanent computer solution since we are running it on a trail license. We also need some help getting someone from outside our area to try to remotely connect to our node.
Hopefully Karl and myself can give a little demo this next social night.
I want to start a series of post on our other less used ham bands, and to start the series out one of our most over looked bands the 220 Mhz 1.25 meter band. The band has access to every license class so any amateur radio operator can use this band. Here is an interesting video I found that talks about the 1.25 meter band. Take a moment and you might learn something new.
It’s a great band, with characteristics similar to 144-148 MHz, and has certain real advantages over the 2 Meter band.220 MHz is alive and well in areas where hams aren’t afraid to experiment and think outside the normal 2-Meter/70-CM realm. While there isn’t a ton of commercially available amateur equipment available these days for 220 MHz they can be found new and used. With a quality radio, you can drive around almost anywhere in CSQ mode and the noise floor is next to nothing. Radio amateurs will lose this band unless we make better use of it than we do at present. Amateurs in the US lost 220 to 222 MHz some years ago.

1.25 Meters (222-225 MHz) Band Plan:
|222.1||SSB & CW calling frequency|
|222.10-222.15||Weak-signal CW & SSB|
|222.15-222.25||Weak signal, repeater inputs, control|
|222.25-223.38||FM repeater inputs only|
|223.71-223.85||Local coordinator’s option; FM simplex, packet, repeater outputs|
|223.85-224.98||Repeater outputs only|
Amateurs are permitted to operate on five frequency channels, each having an effective bandwidth of 2.8 kHz. Amateurs may transmit with an effective radiated power of 100 W or less, relative to a half-wave dipole
Channel 1: 5330.5 kHz
Channel 2: 5346.5 kHz
Channel 3: 5357.0 kHz
Channel 4: 5371.5 kHz
Channel 5: 5403.5 kHz
These frequencies are available for use by stations having a control operator holding a General, Advanced or Amateur Extra class license. It is important to note that the frequencies shown above are suppressed carrier frequencies – the frequencies that appear in your transceiver’s tuning display when your transceiver is in the USB mode.
CW operation must take place at the center of your chosen channel. This means that your transmitting frequency must be 1.5 kHz above the suppressed carrier frequency as specified in the Report and Order (see Table 1). Operating at strict channel-center frequencies may come as a disappointment to many, but cooperating with the NTIA is key to expanded privileges in the future.
The channel center frequencies are:
Channel 1: 5332.0 kHz
Channel 2: 5348.0 kHz
Channel 3: 5358.5 kHz
Channel 4: 5373.0 kHz
Channel 5: 5405.0 kHz
