“Ask not what your radio club can do for you, ask what you can
do for your radio club…” (Deliberately lifted from John. F. Kennedy’s 1961 Inaugural Address)
K8JK
Time flies when you’re having fun, and this year has been no exception to that old line. Most of the official
“summer season” is now history. Soon we’ll begin to complain about how cold it is. Already I’ve noticed
the evening daylight hours getting shorter. Additionally, I’m a little behind on my antenna “to do” list before
the weather makes a turn. Here’s hoping you are all in better shape with those outdoor radio projects.
I mentioned last month about the awesome power and capabilities within our little radio club. I believe this
is a huge asset that everyone can take advantage of. In retrospect I realized some folks reading this newsletter may NOT be members of the LARK. Even so, you can still take advantage of this talent by attending our
Saturday breakfast. The “official” LARK breakfast is held on the FIRST and THIRD Saturday of most every
month, beginning around 8 AM. We’re meeting at AMERICUS GRILL in Brighton. The truth is that there are
many of us who get together most every Saturday morning at the same location and time. Drop by, enjoy
the opportunity to talk, and enjoy a pretty good meal.
Sometimes you’re wrestling with a technical issue or challenge that may seem overwhelming. LARK members may be able to assist you, but unlike service that you pay for, there are a few friendly guidelines. First,
let us know you’re having an issue. The LARK breakfast or a club meeting might be a good place to share
that information. Second, it’s good to plan and prepare in advance if you are attempting to solicit help. Timing can be everything in trying to gather up human resources for your next big antenna project. Finally, consider offering something in return for all the effort. This doesn’t have to be complicated or expensive; you
might want to bring a snack to the next meeting, or perhaps provide snacks after we complete your project.
These three steps may help you accomplish more with amateur radio.
Snacks and treats at our club meetings are generally provided by your fellow club members. No club funds
are spent on those munchies. I encourage all members to participate, either by providing edibles or donating a few dollars to the cause. Feel free to approach any LARK officer about this.
Beginning in January, we’d like to start a new feature article in our LED newsletter, called Ship Shape Shack
Shots. It’s really simple, just take a picture of you at the controls of your radio gear, and send it to or give it

From the Program Director:
Following last month’s presentation, the consensus opinion of the Klub members was that we should continue to pursue a better understanding of Packet Radio for a few more months. We took a “fifty thousand
foot” look at how packet operates and realized that there is a lot going on behind the scenes to assemble
packets, calculate and perform error checking, modulate and demodulate the RF from the radio and do all
this with minimal operator involvement. But, we don’t need to understand the in’s and out’s of AX.25 Link
Layer Protocol to operate packet radio any more than we need to understand the code running the engine
control computer to drive a car. With that in mind, the September program time will be devoted to a review
of basic Packet Radio equipment and a demonstration of packet communications. We’ll set up a couple of
stations using the SPARK kit and similar equipment and barring any recurring problems with Windows 10
this should all work well. Actually, this works well with Windows XP so we’ll stick to that.
Switching topics, I‘d like to discuss coaxial cables. Coax comes in many
physical sizes and characteristic impedance’s. We are most familiar with
the 50 and 75 ohm types found in diameters ranging from about 0.125 in.
to 0.5 in. Coax also comes in larger diameters, but then we usually refer
to it as “Hardline”. The construction of coax varies and we can find solid
and stranded center conductors, various types of dielectric materials, various types of outer shield construction, and finally, different outer covering
materials. By using the “RG” designator on the coax you can determine
some basic information about its construction. For example, RG-58/U has
a 50 ohm characteristic impedance, a diameter of about 0.193 in. and it
has a solid center conductor. If the designator were RG-58A/U it would
indicate a stranded center conductor. Unfortunately, the RG designations
are no longer controlled so you will need to refer to the information provided by the manufacturer to determine other properties such as dielectric materials, wire sizes, and outer shell composition.
The characteristic impedance of a coaxial cable is determined by several factors including the composition of
the dielectric material used to insulate the center conductor from the shield, the outside diameter of the
center conductor and the inside diameter of the shield. The characteristic impedance of an air insulated coaxial line can be found using the formula: Zo =138 log (b/a) where b= inside diameter of the outer conductors and a= outside diameter of the inner conductor. The use of a dielectric material other than air will
affect the characteristic impedance (and complicate the formula).
Say what?
So, after all of that, what I really want you to understand and appreciate is
that coax cable needs to be handled with care. Kinks and sharp bends can
break the center conductor. They can also alter the spacing between the inner and outer conductors and that will change the characteristic impedance
of the coax. One small kink might not change the impedance much, but several could introduce enough of a change to cause an increase in SWR and
losses. Treat your coax carefully. Wind it up in smooth coils and NEVER wind
it on your arm like you might a rope. Handled properly, coax will last for
years and work when you need it to.

Perhaps the Program Director can
explain this in our next meeting.

to the newsletter editor. Not only is this a great way to get your picture
in the LED, it will motivate you to clean up your radio room! (You might
even discover something you’ve been looking for under that pile of magazines and “important stuff”). I want to kick this off at the beginning of
the year because it’s going to take me that long to clean up my own
station!
Finally, some LARK members will be demonstrating amateur radio to a
Howell area Cub Scout pack in September. If you know of an organization
or group that might want to learn more about our hobby, make sure you
let an executive team member know.

Awards and Recognitions
Congratulations to Les Butler. August 10th marked his one
year anniversary on HF. In one year he has worked 180
countries, with 169 confirmed. Les uses what he calls an
‘ultimate tracking sheet’.
Are YOU earning awards? Please send the details to w8mck@arrl.net to be recognized in the LED.
Do you operate on 160?
The ARRL also commented on the FCC's proposal to amend its Part 80 rules to permanently authorize radio buoy
operations on the "open sea" under a ship station license in the 1900-2000 kHz band, which the Commission recently elevated to primary for Amateur Radio. The League said there is "no evidence of compatibility" between Amateur
Radio operation in the band and the "heretofore illegal" ocean buoy operations there.
"Should the Commission proceed with its proposal...to make the 1900-2000 kHz band available to commercial fishing vessels for use by radio buoys on the open sea and to include them in the equipment authorized as part of a ship
station license, it should not do so by means of a primary allocation for these devices in ITU Regions 2 and 3 as proposed," the League said. "The entitlement to utilize radio buoys should be on a secondary basis to the Amateur Service (and other
radio services operating in the 1900-2000 kHz band), and the buoys should be prohibited from causing harmful interference to
Amateur stations without qualification."
In a footnote, the ARRL said, "The record is silent heretofore as to the need to use radio buoys in this frequency range. There is no
information as to the necessary path distances for these devices and why a band with very long distance propagation is necessary
for these buoys rather than VHF or some other suitable alternative."

information can be sent via email to W8MCK@arrl.net or given to her at any meeting.
 VE Report: No one presented for testing.
Old Business: None
New Business:
The Amateur Radio Parity Act of 2015: John Wilson K8TTI began a discussion about this pending legislation and whether LARK
could or should offer financial and/or other support for these bills (H.R.1301 in the US House of Representatives and S1685 in the
Senate). If enacted, these bills would direct the FCC to extend its rules relating to reasonable accommodation of Amateur Service
communications to private land use restrictions.
All are urged to learn about these bills and to write their congressmen to state their position on these topics. For a full explanation of these bills and to find the addresses of your congressmen, please refer to http://www.arrl.org/amateur-radio-parity-act.
Request for Amateur Radio Demonstration: A local Cub Scout group requested a demonstration of Amateur Radio to take place at
the Peacemakers Gun Club in September 2015.
Pat Shannon W8LNO motioned to adjourn; seconded by Ralph McChristy N8RBA. Meeting adjourned at 9:24 p.m.
50/50 raffle won by John Wilson K8TTI.
Respectfully submitted,

The Livingston Amateur Radio Klub maintains
the 146.680 (negative offset, 162.2 CTCSS) and
also the 444.525 (positive offset, 100.0 CTCSS)
repeaters in Livingston County.
FCC website maintenance in early September
will make the Universal Licensing System (ULS),
the Electronic Comment Filing System (ECFS), the Electronic Document Management System (EDOCS) and other public applications
unavailable for more than 5 days. The Commission said the outage
will begin at 2200 UTC on Wednesday, September 2, and continue
through the Labor Day weekend. The maintenance work should be
completed by 1200 UTC on Tuesday, September 8. During the ULS
outage, it will not be possible to file any Amateur Radio applications.
In a blog, "Modernizing the FCC's IT," FCC CIO David Bray said that
with the world and the technology we use changing rapidly, "the
information technology used by the Federal Communications Commission must change as well." Bray said the FCC has "made significant progress to upgrade and modernize our infrastructure, and we
continue to work on modernizing the FCC's legacy IT systems with
the resources we have available."
"We understand that this temporary downtime before and during
the Labor Day Weekend may be inconvenient for some FCC stakeholders," Bray added.
Did you know?
