Another month has come and gone, spring is just
around the corner and I am ready. Before Christmas, I
shattered my elbow and have not been able to do much
with it the past few months. I am still on restricted duty
at work, but am starting to get some use out of the arm.
Doesn’t look like I will be back to health until late
summer or early fall. Anyway, enough wimping and on
with the Ye Ed.
This month we will be starting our 2015 meeting
Cycle. The program for March the GCARA will host the
ARRL Great Lakes Vice-Director as he answers
questions on the direction of RRL and amateur radio.
Next month we will be holding the GCARA Annual
Auction. If you have never been to one of our auctions,
you are in for a treat. The are a lot of good deals and
unique items on the auction block. If you have
something you want to sell (it does not have to be radio
related) and are will to sell for a good price, (you know
hams) you are invited to bring your items for Richard,
KC8RP, to auction off. Hope to see you then…with or
without items to sell.
Well, I am going to wrap it up for this month and will
back next month.

Meeting
A Cold But Sunny Day Next To the Pemi
de Tim Carter – W3ATB
Last year the first day I operated outdoors was on March 17th. My outdoor radio colleague, Jim Cluett, W1PID
was itching to get out because it’s been such a wretched winter here in the Northeast. The brilliant sun spoke to
Jim in the morning like a singing siren serenades a sailor.
We were soon both to discover that Mother Nature can be such a teasing temptress.
We had to hike about a quarter of a mile from the parking lot at Profile Falls to the edge of the Pemigewasset
River. The walk through the woods was magical even though you had to look down almost all the time to stay
on the narrow hard-pack snow trail. If you strayed from the trail, you post holed up past your knee in cold
snow.
Today the only condition that was the same was the sun. Last year it was 37 F and today it was 21 F. Last year
there was no wind, this year a stiff breeze was lashing Jim as he was trying to get the halyard up into the tree to
pull up my par end-fedz antenna. I was busy getting my HB-1B rig set up.
I’ve discovered working with Jim in cold weather that you need to waste no time getting antennas up into trees.
If your fingers get cold, it’s hard to operate and the fun of the adventure diminishes as rapidly as water puts out
fire.
Once the antenna was connected, I started to check the 20-meter band for activity. It was dead to me only
because I had the filter on the HB-1B set too tight. Jim rotated it counterclockwise and then we could hear
operators.
While I was trying to find a strong signal, Jim got out his small camping alcohol stove and lit it with a match.
It was just what we needed to take the chill off our hands. We both had thick wool mittens and gloves and it’s
just about impossible to operate the radio and paddles with them on.
“Do you want to go? Are you cold?” Jim asked me as I was tuning around.
“No way. We’re not going to get skunked,” I replied.
Jim scored first lassoing NM2L/M. He was 599 into us and he gave Jim a 599. “I’m all warm now after that
QSO, so it’s your turn!” QSOs do that to Jim. He loves CW contacts.
Moments later I was able to sneak in my call to W9JVW and he came back. He gave the little HB-1B a 459 and
I gave him a well-deserved 579.
“Let’s get out of here!” Jim didn’t get an argument out of me.
As we walked back towards the car, we stopped in the large field to just soak up the sun. The wind had died
down a bit and the rays of the sun revived us and erased the pain we had just ten minutes before.
It didn’t take long to get back to the car and we both agreed it was the lower limit of us being able to operate
outdoors.
Without the sun, it would have been impossible. In just a few weeks, bare ground will start to appear and our
operating options will be as broad as the side of a battleship!

RESTRUCTURING: ARRL ASKS MEBERS TO COMMENT ON DRAFT HF BAND PLAN PROPOSALS
Your opinion could help shape future amateur rasio bandplans. Skeeter Nash, N5ASH,
The ARRL High Frequency Band Planning Committee is recommending band by band changes to the overall High
Frequency bandplan and wants input from its members before April 19th.
The proposed changes differentiate among Automatically Controlled Digital Stations known as ACDS, narrow RTTY
and data modes having a bandwidth no greater than 500 Hz, and wider data modes having a bandwidth up to 2700 Hz.
Here are some of the highlights for the most popular bands.
Starting with the 75 and 80 meter spectrum, the committee recommends that the League petition the FCC to move the
boundary between 80 meter RTTY and data and the 75 meter phone/image band from 3600 to 3650 kHz and restoring
that segment to General and Advanced class licensees. Members are also being asked if the League should petition the
FCC to shift the ACDS band segment from 3585 to 3600 kHz higher to 3600 to 3615 kHz making it consistent with the
International Amateur Radio Union Region 1 and 2 band plans. Also should it ask to extend the current Novice and
Technician CW segment up to 3650 kHz as well as adding 80 meter RTTY and data privileges for these licensees.
At 7 MHz, the committee has concluded that it would be unrealistic to try to bring the ARRL 40 meter band plan into
alignment with the rest of the world. They say that in Regions 1 and 3 where 40 meter operating patterns developed
when the entire band, including phone, was just 100 kHz wide and is still only 200 kHz. While 7040 kHz is a
recognized RTTY and Data DX frequency in the band plan, it believes that the best place for other RTTY and Data
activity in the United States is above 7070 kHz.
For 20 meters the committee suggests using the 1 kHz International Amateur Radio Union backed Northern
California DX Foundation beacon network frequency at 14.0995 to 14.1005 MHz as a dividing line between wide
ACDS in the 14.1005 to 14.112 MHz segment, and narrow ACDS from 14.095 to14.0995 MHz. It also recommends
14.070 to 14.095 MHz for RTTY and narrowband data, noting that so-called weak-signal data modes often are used
between 14.070 and 14.078 MHz.
On 15 meters, the committee recommends that 21.070 to 21.090 MHz for narrow RTTY/data modes, the FCCmandated ACDS segment of 21.090 to 21.100 MHz for both narrow and wide automatically controlled data station
activity, and above 21.100 MHz for any additional wide data activity. The ARRL Board also wants members to
comment on the desirability of adding RTTY and data privileges for Novices and Technicians in their existing 15 meter
segment, where theyre now limited to CW.
On 10 meters the committee only recommends that wide data be confined to the FCC-mandated ACDS spectrum at
28.120 to 28.189 MHz be separated from narrow RTTY and data modes at 28.070 to 28.120 MHz.
Proposals for the other High Frequency bands can be found in an article on the ARRL website at tinyurl.com/HFbandplan-proposal. The League has also set up a web page at arrl.org/bandplan where members can comment. Those
wishing to offer more detailed proposals may do so by e-mail to bandplan (at) arrl (dot) org.
The HF Band Planning Committee will deliver its final report at the ARRL Board of Directors July meeting.

With Just a WSPR
By Dan Romanchik, KB6NU
It's really amazing what you can do with computers in
amateur radio, and there's been an explosion in the
number of digital modes. One interesting mode that I've
recently been introduced to is WSPR, which is short for
Weak Signal Propagation Reporting. The protocol and
the original WSPR program was written by Joe Taylor,
K1JT, and is designed for sending and receiving lowpower transmissions on the HF bands to test propagation
paths.
Mini-Circuits 10.7MHz low-pass filter, then to a 1:1 balun,
which is connected directly to the dipole elements.
Joe says, "The antenna is just a dipole taped up to the
walls of my living room and hallway." As you can see he
made the balun and dipole from 24 ga speaker wire.
The performance of this setup has been kind of amazing.
In one e-mail, Joe reported, "Your toroid seems to be
working well. Got the balun and antenna finished and
executed seven WSPR transmissions from the
Raspberry Pi. The WSPR reporting website WSPRnet
(http://wsprnet.org) came back with a couple dozen
reception reports; typical distance is ~300+ miles, max
was 593 miles." In a second e-mail, Joe writes, "Did a
few more beacon transmissions and checked the WSPR
signal reports again. Someone picked up my 5 mW
signal from 1010 miles away in Canada."
I won't try to cover all the technical details here. There
are several sites that cover them pretty well:
* Wikipedia: WSPR (http://en.wikipedia.org/wiki/
WSPR_%28amateur_radio_software%29)
* G4ILO's Shack: WSPT - Distant Whispers
(http://www.g4ilo.com/wspr.html)
I was introduced to WSPR by my friend, Joe, AC8ES. He
posted a message to our club mailing list asking if
anyone had a toroid core that he could buy to make a
QRP balun for 10 MHz. When I asked what he was going
to use it for, he said that he was making a WSPR
transmitter with a Raspberry Pi, and the balun was for
the dipole he built for it. He said that he'd gotten roped
into doing this because he'd attended a local Raspberry
Pi users' group, and when he mentioned he was an
amateur radio operator, they encouraged him to try this
project.
Joe's turned into quite a WSPR fan. He's even written an
Android app - WSPRnet Viewer (https://play.google.com/
store/apps/details?
id=com.glandorf1.joe.wsprnetviewer.app) to retrieve and
displays report from www.wsprnet.org. Tapping on a
specific report displays more details about it, along with a
world map that shows transmitter and receiver locations.
Unfortunately, I don't have a Raspberry Pi, or I'd try this
as well. I do have a BeageBone Black, but there doesn't
seem to be software that I can download and install as
easily as the Raspberry Pi software. That being the case,
this might be a good excuse to purchase one of those
new, cheaper RPis.
How could I refuse a request like that? I have a whole kit
of ferrite cores, and after some back and forth, we found
a small core that he could use.
The software he chose is WsprryPi (https://github.com/
JamesP6000/WsprryPi). It's described a "Raspberry Pi
transmitter using NTP-based frequency calibration." It
uses a GPIO port to generate WSPR signals anywhere
from 0 to 250 MHz. Joe said that there are several
Raspberry Pi programs that run WSPR, but that he
chose this one because it seemed to have more features
than the others.
-------------------------------------------------------------------When he's not digging through his junk box or teaching
amateur radio classes, KB6NU writes about amateur
radio at KB6NU.Com. He has just released The CW
Geek's Guide to Having Fun with Morse Code. The book
is available on Amazon.Com or on KB6NU.Com.
Figure 1 shows Joe's setup. Since the output generates a
square wave, a low-pass filter is needed to filter out the
high-frequency components. As you can see, the GPIO
output is fed through a 0.1uF decoupling capacitor into a
