Digital Communications Guide

Posted by Harrison W1HAF on February 28, 2015 at 6:55 AM Comments comments (0)

A very informative and educational guide has been added to the Documents section of the web page.

Please take a moment to download and read the Digital Communications Guide so that you will understand the diffrences between D-Star, DMR, and C4FM.

The paper was written by Yaesu Vertex which was a subsidiary of Motorola. It does a very good job of describing all three digital modes.

Our Club has decided to provide current technology for our members to use. We have recently changed our 448.975 mhz to a UHF DMR repeater on the CT ARES and DMR-MARC networks.  This system is a statewide system and provides a clear and reliable network for Emergency use. It also has the ability to be used on the DMR-MARC World wide network.

We have decided to replace our aging 146.97 repeater with a brand new Yaesu System Fusion DR-1X repeater. Yaesu is currently offering a promotion for clubs to obtain these new repeaters for just $500.00. This is a $1,200.00 discount off the regular price of the repeater. The new repeater is a dual band VHF/UHF repeater that can be configure to operate in Digital, Analog, or Auto modes. This will allow existing users to continue to still use analog radios while allowing those who wish to try C4FM digital the opportunity to buy and try this mode.

We are considering replacing the 146.67 repeater with a D-STAR repeater as a trial to allow club members with D-Star the ability to communicate locally. This would also allow traveling hams the ability to communicate to local hams while on vacation or passing through our area. If we can secure network acces then this repeater could be connected to the worldwide D-Star reflector systems.

The vision of our club is to provide current technology for our members and all members of the amateur community. This will provide the opportunity for experimentaion with new modes of operation and hopefully increase interest in our hobby.

I am exicted to be able to have the opportunity to experiment with all these different modes of operation.

If you are interesed in trying the Yaesu C4FM digital mode or are just in the market for a new dual band portable radio Gigaparts is offering the Yaesu FT 1DR HT for $289.00 right now. This radio also has built in GPS and APRS modes along with offering analog and digital voice modes.

DMR ON THE AIR !!!

Posted by Harrison W1HAF on October 27, 2014 at 7:20 PM Comments comments (1)

The 448.975 UHF repeater is now on the air. You will need a UHF DMR Radio and you can program it to the 448,975/443.975 repeater. Go to the dmr-marc.net web page and you can find more information on the data to you will need to program into your radio.  We have associated our club with the CT ARES group and this repeater will be used for ARES functions when needed.  The standard DMR-MARC talkgroups are also on the repeater and can be used to talk World Wide and Nation Wide. This repeater works great and has great coverage. It is currently located in Ledyard CT . If you are listening to the analog frequency you will hear data bursts every three or four minutes. The old analoge repeater has been left on the air for now and can be used when the digital repeater is not being used. The grandfather clock ID has been shut off along with the squelch tail. The repeater still works fine when activated. There is a two second delay before you can talk. This may change in the future as the DMR activity increases. If you are interested in DMR then come on out to a meeting and see what it is all about.

DMR Radio

Posted by Harrison W1HAF on June 11, 2014 at 7:00 PM Comments comments (0)

Hello All,

At the June club meeting, Troy, KB1BVF, presented an oportunity to have a group of amateurs who are building out a DMR (Digital Mobile Radio) Network in New England, come to one of our meetings to discuss DMR radio and how it works.  The club voted to pursue this proposal to see what this type of communications is all about and if we would be interested in converting our UHF repeater over to this network.

If you would like to learm more about this type of communications you can check out the following links.

We are looking forward to hearing more about this type of communications at a future meeting.

2013 Club News

Posted by Harrison W1HAF on February 4, 2013 at 3:20 PM Comments comments (1)

Happy New Year everyone.

Sorry for the lack of posts.I have been kinda busy lately. Larry, KB1QQM, our new Club President has some great ideas to get the club going. Please come and support your club by attending a meeting and paying your dues.

We would like to replace the 146.97 repeater this year and could use some support both physically and financially. We are also planning on moving out of the Fargo Road water tower and into the Town Communications building on the same site. This would be a great improvement due to the fact that the building is clean and climate controlled. It also has a built in back up generator. We wil need help when we make the move so stay tuned.

I would like to ask everyone to please monitor the club repeaters. I have heard of several amateurs who have come to our area have tried to make contacts on our repeaters but no one answered them. I know that everyone is busy, but maybe we can try to listen to the repeaters in case someone needs assistance. It would be nice to hear more activity on the air.

73, Harrison, W1HAF.

Easy to use APRS program

Posted by Harrison W1HAF on August 28, 2012 at 7:00 AM Comments comments (0)

I recently came across a newer APRS program that is extremly easy to use. The program is APRSISCE. This program was intially written for use on Windows CE devices but works well in all windows environments. I downloded the windows 32 bit program and followed the instructions to install it. When it initially opens it asks you for your callsign. After inputing your callsign and clicking OK you are now on APRS via the internet. All you need to do is to zoom in on your current location and center the crosshairs on the map over it. Then click transmit and your position is placed on the map. That was it!

If you are a registered user of an APRS program already you can enter your APRS server validation number on the setup screen so that you can transmit and access the other features of the program. The program can be directly connected to a TNC and radio too or to AGWPE and your sound card to a radio. I have used it in all of the above configutions and it worked well.

The best thing that I like about the program is the maps. As long as you have an interenet connection you dont have to mess with setting up maps. This is what I found a little challenging on UIView32. I think that this is a great program for all hams that want to see APRS in action and even put themselves on the map and have the ability to message other hams.

Check it out at http://aprsisce.wikidot.com/.

See you on the APRS.

It is with a sad heart that I must inform you of the passing of Donna Magee, KB1RPP, of Waterford CT. Donna passed in her sleep after her couragious battlle with cancer on Saturday morning. Her husband Larry, daughter Bonnie and family were at her side. Donna was a very active an enthusiastic member of our club who enjoyed participating in Public Service evernts. She was a past net manager for the Eastern Connecticut Traffic Net prior to her illness. Donna loved checking into all the Nets including the ARES Net. New London County Weather Net, and Nutmeg Traffic Net. Her husband Larry, KB1RPK , supportted all of her activities by helping set up her antennas and shack.


Larry ,KB1RPK,  has asked that if anyone had any photos of Donna or memories to please email them to him at [email protected]

 

Please keep Larry and his family in your thoughts and prayers.

Harrison W1HAF
