HELLO, TESTING, TESTING Bill Owens AD5EW

Our Beginning

As with so many things we do in life, we stand on the shoulders of those

who have come before us. And this is true with the RWK Volunteer

Examiner (VE) Program. Dick Morgan, K6RAH, Dave Russell,

W2DMR, and Don Bowen, K5LHO, were our VE founding fathers, so to

speak.

It all started when Dick, our President in 2012, asked Dave to look into

what it would take to implement the ARRL VE testing sessions and to let

the Board of Directors know if a licensing program would be beneficial

for our Klub.

Dave quickly added Don to the discovery mission, and soon both were

attending several local clubs but especially the Garland VE Team. Janet

Crenshaw, WB9ZPH could not have been more helpful. She and her team

were happy to show Dave and Don the ropes.

Dave and Don concluded that RWK and our namesake City, Richardson,

would benefit from incorporating an amateur radio license testing

program in the Klub’s menu of ham radio activity offerings.

The Heavy Lifting

Dave and Don learned the policies of the ARRL VE program, created

forms and procedures, and recruited an all new VE’s who already were

accredited or were willing to become accredited in short order.

As if that were not enough, they had to locate a place to hold the sessions.

In typical fashion, a large number of RWK members took the Volunteer

Examiner, open book test. These new examiners, together with a couple

April 2018 RWK President’s Corner

It was a relatively calm month of

March. The most notable area event

was the always great IARC Hamfest

at the Betcha Bingo Hall in Irving.

This hamfest is a great venue for

shuffling excess ham gear among

various members of the local

amateur radio community. You can

appropriately describe me with the

idiom “one man’s junk is another man’s vintage

electronics” because I managed to lighten the load of a few

sellers at the event. I was also happy to see lots of other

RWK members there enjoying the company of others that

share our common passion for the hobby.

The March meeting presentation, by our very own Dave

Russell W2DMR, was on antenna analyzers. Judging by the

questions, the presentation was very well received by the

attendees. Dave covered both theory and practice with an

emphasis on helping users make an informed purchase

based on desired features. Bob Coelln KG5JL also showed

us his home-brew Arduino-based antenna analyzer based

on the article in the November 2017 QST issue.

Mark Beebe K5YOL is our VP responsible for scheduling

the programs for the general meetings. He has been very

busy lining up some truly outstanding programs for the

coming months. As you may have already read on the

website, Frank Krizan KR1ZAN will be presenting on the

Outernet Project at the April meeting. This is a satellite-

based form of data-casting that provides various media

content to the far reaches of the globe.

In May, Carl Solomon W5SU will be preparing us for Ham-

Com by giving us some pointers on what to look for in used

ham gear if we’re thinking of making an acquisition at the

event. FT8 Mode is the latest bright shiny object in the

amateur radio digital world and Dick Morgan K6RAH will

be bringing us all up to speed on that topic in the June

meeting. Mark has also lined-up John Padgett, from

PhaseCom, for the July meeting to give us a tutorial on

Lightning Protection/Grounding. For the August meeting,

Bill Brady KF5ZBL and David Cappello KG5EIU will be

President’s Corner

making their much-vaunted presentation on

Digital Voice Hotspots.

The Klub is also about to shift into high-gear

in preparation for this summer’s Field Day

event on June 23-24. The City of Richardson

has graciously offered the use of the EOC

again this year. We were happy to accept their

generous offer. Reserve the weekend and

watch the website, Facebook page, and your

email for details.

At the April Board of Directors meeting we

also discussed lots of exciting possibilities for

our Klub repeaters. So stay tuned for

announcements in the coming months as we

roll-out new features and capabilities.

On a personal note, I finally got a new HF

antenna back up after my old, home-brewed

dipole got ripped out of a tree during a storm.

My new antenna is a store-bought all-band 80-

6M MFJ-1777 Doublet. I also have an LDG

RT-100 remote tuner but I haven’t

permanently installed it on my chimney yet.

I’m really looking forward to getting back on

the air after more than a year offline.

RWK Wednesday

"Hungry Hams" Lunch

The RWK lunch bunch meets each Wednesday at

noon at Sonny Bryan's BBQ on West Campbell

Rd. two blocks East of Coit Rd. All are invited to

enjoy the benefit of a lot of "eyeball QSOs."

NOTE: On the first Wednesday of the month,

RWK helps the City of Richardson conduct siren

tests, so lunch is delayed until around 12:30 P.M.

If you go often, you should get your "frequent

customer" card. If you don't yet have one, get one,

for a free sandwich and cobbler after 10

purchases of any kind. Of course, members of

other ham clubs and guests are very welcome to

join in the fun and fellowship.

of others from the WB9ZPH VE Team, held the

first RWK VE session on May 5th, 2012 at the

Richardson Senior Center.

In October of 2012, the VE session was moved

to St. Barnabas Presbyterian Church and the day

and time was changed to every third Thursday of

each month at 7PM. The VE session still meets

at that time.

Dave continued to manage our VE program until

July 18th 2013 when he wanted to pursue other

interests, one of which is the Elmer/Mentoring

program for RWK.

The Next Chapter

On July 18th, 2013, Bill Owens, AD5EW,

assumed the VE Liaison and Session Manager

position for RWK.

The license testing program has continued to

flourish, since its inception we have administered

424 individual tests to 324 candidates, and our

VE’s have worked over 1500 hours of volunteer

time.

The “secret sauce” of our success is due to our

VE’s and their helpful and friendly attitude. We

all want to see each candidate succeed. To

accomplish that, we strive to offer a relaxed, quiet,

and non-hurried atmosphere. Remember, all of the

VE’s are hams and we all have had our own

experiences when we took our tests. We want each

person to have the best chance of getting that new

ticket or upgrade. The candidate has worked hard

learning the material, we don’t want to add to

those common jitters of taking a test.

As much time and work as it takes to pull off a

great testing program, we do this because we

derive pleasure from seeing a new ham or

currently licensed ham, upgrade. It is such a great

feeling seeing the smile on someone’s face after

they have passed the exam. It is great knowing we

had a part in their achievement.

Here are the VE’s who have administered exams

since January 2017 through February 2018.

Ham of the Month

Scott Greeson, KG5MKC

Where were you born or where did you grow

up? Born in Dallas, 5th generation Texan! I spent

most of my life in Texas but my father was in the

Air Force. As an "Air Force Brat" I spent time

oversees in both England and Spain only to come

back to my home state but a little further south

(San Antonio). What age were you when you first got

interested in ham radio? Seriously interested

when I was 35.

Who got you interested in ham

radio? Hurricane Katrina. I was in Louisiana at

the time in emergency management. I saw first

hand the great benefit of what others had called

antiquated technology. That “antiquated

technology” saved a lot of lives and provided a lot

of benefit for response and recovery efforts while

we saw numerous failures of "modern

technology". I was sold so to speak. I made a

point to work with our HAM operators via

RACES, ARES or just HAM Operators

independently from that day on. There is a lot of

know how in this field and a lot of passion. When did you get licensed? Although I had

interest for numerous years it took me until

2016. I received some needed prodding from my

Elmer Kevin Sims, and my RACES Officer Roger

Stierman, to finally take my classes and pass my

test. It was a great day when that happened.

Why did you join The RWK? Many of the

City's RACES members are proud members of

RWK. They told me of the great camaraderie of

the club and the opportunity to learn. It seemed

like a natural choice to make. I have enjoyed several presentations most recently the Collins

presentation since joining.

Please tell a friend about us, come take your

upgrade from us, or if you would like to be a

VE, give me a call at 972-380-2859 and I will

make sure you get what you need to become

one. It is easy!

I hope to hear you on the air and/or see you

soon!

RWK Siren Testing Services

The City of Richardson tests emergency

sirens on first Wednesdays, at noon

(weather permitting). We do not conduct

the test if the weather looks threatening,

to avoid confusing residents. Hams

assist each month by going to a

designated siren, checking into the net

on 147.120 MHz, watching and listening

to the performance of the siren, then

reporting on the net. Most sirens have

an assigned ham, but there often are

unassigned sirens. New hams are

welcome to participate and learn!

Please contact Don Bowen K5LHO,

972-235-3063,

if you can help with siren tests.

Simple Arduino-based Frequency Counter

by John Di Filippo - AF5MN

I acquired an old but working 2MHz function

generator from a ham at the Main Trading

Company Ham Radio Day in Paris, TX a couple

of years ago. It worked great, but the frequency

setting potentiometer covered a decade and was

difficult to set with any degree of precision

without the aid of an oscilloscope or external

frequency counter. I thought a simple digital

frequency display would make a nice addition to

an otherwise great piece of test equipment.

Briefly I contemplated my buy versus build

options and then made my decision.

For me, the lure of electronics is primarily hands-

on experimentation and building. To quote

National Semiconductor analog designer Robert

Pease, “my favorite programming language is

solder.” Within reason I’d much rather build it

myself and maybe learn something along the way

than buy an off-the-shelf product.

When I have a specific project in mind I usually

start by googling to see if someone else has

already done the heavy lifting. Sometimes I find

a website or YouTube video with exactly what

I’m looking for and other times I find something

close but must “tweak” it slightly to meet my

specific needs. Very rarely do I find that I need to

start completely from scratch.

Once I’m satisfied that I’ve got a solid design, I

collect the parts, breakout the breadboard and get

to work. Sometimes, but not very often, the

project might eventually migrate from the

breadboard to a permanent, stand-alone

enclosure.

I’ve always been open to better ways of doing

things and that is why I was so intrigued when I

saw Brady Pamplin’s (W5LH) presentation

“What is Arduino?” at the March-2014 meeting.

It seemed from Brady’s presentation that the

Arduino’s breadboard-friendly digital and analog

I/Os, along with the user-friendly Integrated

Development Environment (IDE), had a lot to

offer to the experimenter.

I typed “arduino frequency counter” into the

YouTube search bar and the very first video that

popped up was “Super simple Arduino

Frequency Counter” from a YouTube Channel

called learnelectronics. The channel is run by an

amateur radio operator named Paul and contains

446 videos about electronics, Arduino, Raspberry

Pi, 3D printing, and ham radio.

What caught my attention was the video’s

description that said this was the easiest and

smallest frequency counter the author could come

up with. It just used two components; an Arduino

Nano and a cool little OLED display about the

size of a postage stamp.

Refer to the schematic in Figure 1 to see just how

simple this circuit actually is. Besides PWR

(+5V) and GND, the OLED display only needs

two jumpers to talk to the Nano. The serial clock

pin (SCL) on the OLED display connects to pin

A5 on the Arduino, and the serial data pin (SDA)

on the OLED display connects to pin A4 on the

Arduino. The input is on digital pin D5.

Figure 1. The Complete Frequency Counter

Schematic!

You can get Arduino boards locally at Tanner

Electronics, Fry’s, or Microcenter. Additionally,

you can order them online at Amazon, eBay,

Adafruit, sparkfun, Element14, or many others.

The OLED display is a little harder to come by

locally, so I ordered it and the Nano board from

Amazon.

The OLED display was $7.49 and the Arduino

Nano was $3.95. I know you can find both

cheaper on eBay if you’re willing to wait, but by

ordering from Amazon I had them in two days. I

already had the breadboard and jumper wires as

well as a USB cable with a mini-USB connector

(not a micro-USB connector like your Android

smartphone).

Note that there are two different flavors of OLED

displays. For this project you’ll want to get the

one with the two-pin serial Inter-Integrated

Circuit (I²C or IIC or I2C) interface. Not the one

with the Serial Peripheral Interface (SPI) which

requires four or five pins to talk to the Arduino.

See the Resources section at the end of the article

for a link to the version that I used.

With all the hardware in hand, I proceeded with

implementation. I clicked on the source-code

URL (https://pastebin.com/G6x7tsge) and

cut/pasted the code into a blank sketch in the IDE.

The sketch itself is surprisingly small. That’s

because it relies on additional libraries to handle

the low-level tasks of serial communications,

OLED display control, and frequency counting.

So in addition to the sketch, you’ll need to

download and install the following libraries to the

IDE: Wire.h, FreqCount.h, and

Adafruit_SSD1306.h

Once everything was properly installed I hit the

upload button and voila – it didn’t work! After

more googling I finally determined that the

original sketch was missing one additional library

for the OLED display. I don’t know how Paul got

his original sketch to upload but I had to

download and install the library Adafruit_GFX.h

to the IDE and then edit the library calls section

of the sketch to include it. Once that was done I

once again hit the upload button and voila – this

time it worked!

Figure 2. Arduino Nano and OLED display hooked-

up on my bench and running the original sketch

The first thing you notice in Figure 2 is that the

original sketch uses a small font and displays two

digits behind the decimal point that always read

00. It also displayed the period but only down to

0.01ms which was fine for audio frequencies but

not that useful above 100KHz. For a close-up of

the display see Figure 3.

Figure 3. Close-up of OLED Display using

display.setTextSize(1)

I didn’t really care about displaying the waveform

period or fractions of a Hz and the tiny font size

was kind of a bummer. After more googling I

found out how to enlarge the OLED display font

size. display.setTextSize(1) is the small font and

is what Paul used in his original sketch.

display.setTextSize(2) doubles the character size

which seemed better for my eyes. So I edited the

sketch to use display.setTextSize(2) and re-

uploaded it. The result is shown in Figure 4.

Figure 4. Close-up of OLED Display using

display.setTextSize(2)

I have another laboratory-grade function

generator, a Wavetek model 288, that I know is

very precise up to 20MHz. After playing with the

frequency counter for a while, I noticed that it

didn’t match that closely to the Wavetek or to the

frequency counter built into my oscilloscope. The

Arduino-based frequency counter always read

slightly low with a consistent error of over

2200ppm. I’m not sure what caused this problem.

Perhaps my particular Arduino Nano had a cheap

crystal or ceramic resonator or maybe there was a

problem in the FreqCount.h library. Whatever the

cause I wanted to improve the accuracy if

possible.

After characterizing the Arduino-based frequency

counter (see Table 1) I determined that a

correction factor of 2290ppm was needed, so that

it matched the more accurate signal generator and

the oscilloscope. To implement this, I simply

added a multiplier to the final display.print

statement which improved the accuracy to within

a few ppm.

Table 1. Comparison of actual versus displayed

frequencies.

For my last edit I wanted to get rid of the numbers

behind the decimal point. After more googling I

found a round function could be added to the

display.print statement to accomplish this.

To summarize, the major changes I made to the

original sketch are as follows:

#include <Adafruit_GFX.h> and,

display.setTextSize(2); and,

display.print(round(count*1.00229));

Figure 5 shows what the display looked like

after the three edits above were incorporated into

the sketch. Notice that the driving frequency in

`

this case was 1MHz. Note that it is now within

4Hz (4ppm) of an exact match with the Wavetek

model 288 function generator.

Figure 5. Readout of 1MHz signal after edits to

sketch. Compare the display’s readability to Figure 2.

Final thoughts:

You need a relatively high voltage swing on the

Arduino’s digital inputs for it to recognize valid

H-L and L-H transitions. That’s due to a couple

of factors.

• The specification for a USB 2.0 supply

is 5V (+0.25 / -0.6). That means if you

power your Arduino from a USB 2.0

port its supply can be as low as 4.4V or

as high as 5.25V and still be within spec.

• The maximum specification for a low on

an Arduino digital input is 0.3*VCC or

0.3*4.4V = 1.32V and the minimum

specification for a high on an Arduino

digital input is 0.6*VCC or 0.6*5.25V =

3.15V. To guarantee that the Arduino

sees valid logic levels, it must be driven

on its digital inputs, by a signal that is

greater than 1.83V, and that crosses both

of those thresholds.

• For my application this is not a problem

since the function generator has a TTL

level sync output that can drive the Nano

perfectly well. But for other applications

where signal levels in the tens of

millivolts range may need to be

measured, then some sort of pre-

amplifier will be needed.

I also observed that the Arduino-based frequency

counter could not measure frequencies above

7MHz. I think this is because the ATmega328P

uC is only running at 16MHz, and therefore

cannot sample the input fast enough for accurate

readings above 7MHz. This again isn’t a problem

in my case, since my function generator only goes

up to 2MHz but for higher frequency applications

a pre-scaler may be needed.

I wanted to add commas every third digit to

designate thousands, millions, billions, etc. but

apparently there is no easy built-in command to

do this. I didn’t want to write a bunch of

additional code just to handle that formatting.

It was at this point that I decided to declare

victory on this project. Unfortunately, at least so

far, the frequency counter has not yet made it off

the breadboard and into that elusive permanent

enclosure. But it was great fun doing something

so useful in such a simple and elegant way.

Thanks again goes to Brady Pamplin for

introducing Arduino to the Klub back in 2014 and

to Paul and his learnelectronics YouTube channel

for the inspiration for this project.
