I’ll be presenting a Tech Talk on Solar Energy following the 7 o’clock SEMARA Business Meeting on October 6.
Topics of Discussion
- How Solar Panels work
- Different types of panels: advantages and disadvantages
- Power calculations
- How to wire panels to batteries and load using charge controllers
- The use of DC-DC converters to keep battery voltage constant
I will bring a solar panel and battery pack.
Quick update before tonight’s business meeting:
The Raspberry Pi board for the 900 node which is used to link it into the 900 network was bad. In the picture, the one in hand is the bad one with its replacement being tested behind it. The board is $35, but I had this brand new one that I am donating to the club. Also, the fans in the 900 repeater that cool the PAs have seized. Via Jeff-N1ZZN, we will get replacements next week from another Motorola MSF5000, also at no cost to the club (thanks Jeff).
Planning to get the 900 repeater back on the air when I pick up the fans from Jeff. The 220 repeater wiring is complete with a few level adjustments and programming of the repeater controller remaining. I’d like to be able to make one trip to the repeater site and get both repeaters beck on air together when I get the fans from Jeff.
I hoped to have this all done in August as I previously stated. Let’s aim for next week (again, please don’t hold me to it, but I will try).
Thanks for everyone’s patience during the downtime.

SEMARA sponsored a class for the technician class amateur radio license. The classes were held at the clubhouse at 54 Donald Street, Dartmouth, MA on July 30 and 31 from 10 AM to 5 PM on both days. The total cost was $15.00 per person and this included FCC testing by lead instructor Bob Phinney K5TEC, a volunteer examiner, at the end of the class on Sunday. The results of the program are listed here together with the student’s hometown.

SEMARA’s 224.800 and 927.8375 repeaters are temporarily off the air as of today for a repair and upgrade.
1) The 900 repeater’s IRLP node failed over a month ago and it wasn’t liked to NEAR-900. After a couple of trips to the site, it was determined that I need to re-image the SD card. That node is being repaired and reconfigured and it will now also act as the repeater controller.
2) The 220 repeater will receive the repeater controller that was previously on the 900 repeater. This will allow it to be interfaced to both its own IRLP node (4215) and a UHF link radio for the first time. This will allow the repeater to be configured in a few different ways for linking. More info on its linking status/schedule will be announced soon.
I am working from home this upcoming week which will give me additional free time to work on this project. This is why I decided that now would be a good time to take the repeaters offline and execute the above changes. I will send out another update when progress and/or completion occurs. The SEMARA business meeting is this Thursday and if possible, I’ll try and get it all finished before the meeting, but I cannot guarantee it.
Thank you and sorry for any inconvenience that temporarily being off-air may cause.
Please note: 147.000 and it’s node (4210) are still ON-AIR and are unaffected by this work.

It is with great regret that we announce the passing of longtime SEMARA member David G. Dean, K1JGV of Dartmouth. Dave passed away on the morning of Tuesday, May 17, 2016. He was 77 years old. Dave was a kind gentleman and an all around nice guy who had a strong passion for the things he did. At SEMARA, he will always be remembered as one of our most dedicated buildings and grounds members.
Please share your thoughts and memories of Dave using the “Comments” link at the top of this story. We send our sympathy to Amy and his family for their loss. May he rest in peace.

I’m seeking operators for K2H, the shared Special Event callsign for Massachusetts.
Please let all members of our club know about this opportunity. I can add
both W1AEC and [W1AEC station not available] home station operators to the official W1AEC / SEMARA operators list.
Do you want to have the experience of being called instead of calling to make a contact? You’ll get calls from both domestic and DX operators who want to qualify for the certificate endorsements. As an operator of K2H, you will automatically qualify for a certificate. You can also contact the other 13 Colonies S/E stations to earn your own endorsements.
You’d be surprised at how many contacts you can make with a wire antenna. You can work as many or few hours as you wish during the week. Each operator is self-scheduled by using an on-line calendar to reserve Band, Mode, and Hour blocks of air time. Also, at the end of the week, each operator submits their own Cabrillo logs to the Massachusetts QSO / QSL coordinator and QSO totals to KU2US, event organizer.
More details and the 2016 Operating Guidelines will be available shortly. Meanwhile, go to 13colonies.net for more info. There you can then click on Massachusetts / K2H for other details.
Note: this event is NOT a contest; so 12m, 17m and 30m bands may be used.
Contact me if you would like to participate and/or if you need more information, etc.
