Hamming It Up

K7DAA and KJ6VTP did a Field Day dry run with a new mobile tower recently aquired by KJ6VTP. This was the first time the mast was extended since the tower was acquired several weeks ago. The tower needed some repairs to limit switches, and need some overall TLC. There is some work to do, but the main functions of the tower work well. It is very exciting to have this new tool available to our group here in South County. For this exercise we were gauging how long it would take to arrive on station, deploy the tower, assemble the hexbeam, raise the tower, and get on the air. This was our first go of it, and we were on the air, with the 20 meter hexbeam at about 65′ (of the available 100′) in about an hour. At 4 PM, we were able to make several contacts with excellent signal reports from an FT-857 that we ran with battery power. Next stop Field Day!

Anderson Powerpoles

powerpole05Lopping off the ends of the power connectors on your brand new gear may not sound like a good idea, but it probably is. Anderson Powerpole connectors have become the defacto standard for power connections in amateur radio. They are easy to connect, and come in a variety of amp ratings and colors. It is the power standard for ARES/RACES teams, and a quick, safe, way for hams to come together, and share power at an event or emergency. The connectors themselves are fairly inexpensive. But you will want to make a one-time investment in a proper Powerpole crimp tool. They are about $40-$50. Powerwerx has a great selection of Powerpole connectors and accessories. They also have an excellent tutorial page on how to make proper Powerpole connections. Check it out!

Field Day – It’s Not A Contest. No, Really.

2016 Field Day LogoARRL Field Day 2016 (June 25-26) is quickly approaching. Our local Field Day event will be a joint effort by operators from MHARSGVARC, and SBCARA at Christmas Hill Park in Gilroy. We have significantly stepped up our organization, and our game. We will potentially have 2 crank up towers for yagis, and beams, and dipoles. Oh, my! We plan to run 4A (4 operating stations), and a GOTA (or Get On The Air) where folks new to ham radio can learn about ham radio and make their first contact. We also plan to use laptop logging using the tried and true N3JLP Field Day Software.

Field Day is pretty much as the name implies – In a time of need, could you get your gear, and set up in a field? Do you have power, solar, batteries, generators? Do you have a means to get an antenna up? How about coax, and adapters? Are your power connectors compatible with who you will be sharing power with?

On the lighter side of things, it is a great day for some hobby time, camaraderie, and learning. Points are earned for each contact the team makes, and bonus points are awarded for things like: visiting ARRL officials, local dignitaries, ARES officials, as well as a host of other bonus points and modifiers. Keeping score is fun, but it is not our primary goal. We participate for the fun and friendship.

Set up begins at 8 AM on Saturday June 25th. On air operations will be from 11 AM – 9 PM. (We are not running the full 24 hours.) Stop by and say hi, and bring your friends that are interested in learning about amateur radio. We will put them on the air!

WB6ZVW – New Hotness

2016-05-07 17.42.50After a bit of a hiatus due to technical issues, this great asset to amateur radio for the Bay Area and beyond is back on the air. A group of volunteers made the trek to Crystal Peak this past weekend and removed the old repeater system and replaced everything, from the cabinet to the batteries. In the coming weeks the internet uplinks will be completed and the repeater will also have echolink and IRLP capabilities to further enhance its capabilities. Many thanks to those that helped plan and execute this important update. You can read more details on the GVARC web site.

Tech Night

The first Wednesday of each month, the MHARS 9 PM net holds a “Tech Night” to discuss ham related technical questions. This month we discussed power supplies and the pros and cons of linear or analog power supplies, as well as switching power supplies and the issues that can arise when using them. See our recent post on switching power supplies. Other topics covered were batteries and rapid voltage drops of a Li-On battery, and a host of other topics. Stop by with your questions and somebody will certainly have an answer, an opinion, or know where to find the answer. Be sure to join us on June 1st for the next Tech Night!

Switching Power Supplies

imagesWe need more power! Switching power supplies have been around for some time now. There are many options, features, and price ranges. Some have various power tap options, like CLA outlets, power poles, banana plugs, and basic screw posts. Other features may include meters, or voltage adjustment abilities. Since these are specifically marketed for amateur radios, many have RF filtering to help keep from impeding on your radio session. Some, not so much…

Real Hams Drill Holes

radio-car1You all know “that guy” – The one with the UHF/VHF antenna (or antennas) stuck to the roof or trunk lid and wires trailing off to the side that go through a trunk, door, or window gap. The antenna maintains its death grip on the outside of the vehicle with the mysterious forces of magnetism, via a lip or edge clamp, or something that bolts to your roof rack. You wash your own car and drive a couple extra blocks to avoid parking garages. It’s all for the better you tell yourself. It is also why your significant other won’t let you touch their car.

I was “that guy”.  I also remember when I knew that it was time to no longer be “that guy”.

Magnetic Microphone Mount

no_clipOne thing that seems to make amateur radio folks more squeamish than finding a bag of frogs under their bed is the subject of drilling holes in their vehicle. Drilling holes to mount radios. Drilling holes to mount antennas. Drilling holes to mount a microphone somewhere on the dash. Some of you drill holes for microphone clips, or purchase alternatives that clip onto an air vent, and some of you simply toss the microphone in a cup holder. Today, I am going to share my solution for making a magnetic microphone mount that does not require holes in your dashboard.

Btech 2501 + 220

UV-2501+220 (2)The word of the day is BTech 2501+220. Okay, maybe that is 2 or more words. Several local hams purchased these from Amazon, on sale, for about $100. The results were a bit of a mixed bag. At the heart of it is essentially a UV-5R or UV-B5, with the added band of 220Mhz, in a mobile friendly package, with 25 watts. You can read some some great information at Miklor, so there is no reason to reinvent the wheel here. It is a dual watch radio, with the typical awkward menu system typical of these radios. But once you have programmed a memory location a few times, it goes fairly quickly. And as is also typical, it is easier if you use either software from the BTech web site, or Chirp.

The “mixed bag” experience primarily deals with the transmit audio being fairly muddy, muffled, and dull. One cure is:
