ABOUT ME

 

Please call me Joe.
Thanks for stopping by!

I live in the Bronx, NY.

I was introduced to radio communications by my father in 1979.
I enjoyed talking on CB radios and fiddling with antennas in our tin roof in Comerio, Puerto Rico.

KBBE6156 was my CB license and a Lake 40 Channel Base Station was my first CB radio.

After graduating from High School (1985), I attended Technical Career Institute in

NYC (1985-1987) and took a 2 year course in Consumer Electronics Technology (TV/VCR Repair).

I completed an Associates of Occupational Studies Consumer Electronics Technology. Shortly after I

worked in a TV repair shop / Cable TV Contractor in Long Island City ,N.Y. for 2 years repairing Televisions and VCR's.

The TV/VCR repair business was dying out in my area by 1989 and I had the opportunity to apply to be a Cable TV Technician for Manhattan Cable TV / Time Warner Cable - NOW CHARTER SPECTRUM.

 I have worked in practically all field technician positions and am currently a Tech Operations Foreman in Woodside, NY.

October 16 2017 will mark my 28th year in the Cable TV Industry. I thank God for that!

In 2002 I decided to go back to Technical Career Institute and after 2 years Graduated again with a Associate degree in Electronics Engineering Technology (2002-2004).

My favorite aspect of Amateur Radio is QRP (Low Power)

CW (Morse Code) operation!

Straight Key Century Club (SKCC)

I am member # 10879.

This Club is free to join and has lots of on air activities. If you like CW operation and have never "jumped in" this is the Club for you.  I have made over 100 Contacts and have achieved a T status. TRIBUNE.

SKCC Tribune 10879T TX2.

This award is effective at 0000Z on 07/21/2015

  Here is a typical SKCC contact QSO. Very basic "cookie cutter"  messages. (I used my current and old callsigns as examples).

   HAM 1 ====  " QRL? QRL? " ---  LISTEN AND IF NO ONE IS HEARD ON FREQUENCY I SEND MY CQ CALL

   HAM 1  ==== " CQ CQ CQ SKCC DE KN2A KN2A KN2A K "

   HAM 1 ====  " CQ CQ CQ SKCC DE KN2A KN2A KN2A K "

   HAM 2 ====  " K2MVR"

   HAM 1 ====  " K2MVR DE KN2A  TU UR RST 599 5NN NY NY JOE JOE NR 10979T HW CPY? BT "

   HAM 2 ====  " KN2A DE K2MVR  TNX UR RST ES 559 55N QTH NY NY OP JOSE JOSE SKCC NR 10979T BT "

   HAM 1 ==== " R R K2MVR DE KN2A TU FOR NEW CALL ES 73 73 K2MVR DE KN2A SK EE " 

   HAM 2 ==== " KN2A DE K2MVR 73 ES HOPE TO C U AGN KN2A DE K2MVR SK EE "

   HAM 1 ==== " E E "

   HAM 2 ==== "E E "

The E E is a custom that CW operators have after they end their contact. It is actually a dit dit sound and the other operator responds with dit dit.  Kind of like "Shave and a haircut... DIT DIT "

MICRONOUT CW TRANSMITTER

by Dave Ingram - W4TWJ (SK)

CQ Magazine - April 1996 issue , pages 48-51

 

While doing research on QRPp Transmitters, Bob (AK4JA) pointed me to 

Steve McDonald's (VE7SL)  Radio Notebook.

Steve incorporated  The Micronout CW Transmitter into a Tuna Can and called it

 MINI-TUNA

I decided to build the circuit however I did not have any PCB to build it on. Desperately I ran to the hardware store and purchased a few wooden moustraps and small nails.

I used the wooden board of the Mouse Trap and used Steve's (VE7SL) schematic as a template to build the circuit. I used small nails and soldered all the components. A 7.040 Mhz xtal was used.

I emailed Steve and he was very pleased with my tinkering!

He suggested I call my version of the transmitter

The Mouser-40! 

because it was built on a mousetrap... hi hi!

Thank you Bobby AK4JA for pointing me to VE7SL 's  Radio Notebook and also inspiring me to Build this Circuit

 

 

THREE BLIND MICE TRIBAND CW QRPp TRANSMITTER BY KN2A

The Scoop!

While doing research on QRPp Transmitters, Bob (AK4JA) pointed me to

Steve McDonald's (VE7SL)  Radio Notebook.

Steve incorporated  The MICRONUAT CW TRANSMITTER by Dave Ingram - W4TWJ (CQ Magazine - April 1996 issue , pages 48-51), into a Tuna Can and called it MINI-TUNA.

 

I decided to build the circuit however I did not have any PCB or breadboards  to build it on. Desperately I ran to the hardware store and purchased a few wooden moustraps and small nails.

I used the wooden board of the Mouse Trap and used Steve's (VE7SL) schematic as a template to build the circuit. I used small nails and soldered all the components. A 7.040 Mhz xtal was used.

I emailed Steve and he was very pleased with my tinkering!

He suggested I call my version of the transmitter

The Mouser-40!

because it was built on a mousetrap... hi hi!

 

Well I liked the idea of using a board and nails even though its a bit old school I found it to be so much fun! 

I looked at the values of the caps and inductors for the output filters of the original Micronaut and incorporated the output pi filters for 20 , 30 and 40 meters in the schematic and  built a three band version in one "Mousetrap" wooden board. 

I Named It:

Three Blind Mice CW QRPp Tri-bander XMTR -  Or just "Three Blind Mice"

The bands will be changed by means of three jumpers and changing the xtal for the desired band.

1 jumper from emitter to respective band emitter capacitor

1 jumper from C4 Q1 output to respective band filter input

1 jumper from respective band filter output to output connector (antenna out)

 

My brother Jose Luis (Cartoonist and Artist) did the artwork for the mousetrap board.

I added a small meter to see a indication of output power. The schematic for the meter is not in the original design. It is basically a diode, capacitor and a variable resistor.
It rectifies the output and takes a small sample of the rectified voltage to deflect the meters needle. It can be turned on or off by means of just a alligator clip.
A variable capacitor was also added to the circuit in series with the XTAL. It fine tunes the output frequency + or - 500 Hz.

 

 

THREE BLIND MICE initial  stages

In the photo above you can see 1 jumper from the emitter to the 40m band emitter capacitor, 1 jumper from C4 Q1 output to 40m band filter input and 1 jumper from 40m band filter output to output connector - (antenna out).

I made my first contact on 40m with THREE BLIND MICE on 5/12/15 to VA

Station N7DC @ 20:45 UTC  on 7.113 MHz with 123 milliwatts using a Endfed Antenna

 

 

POWER OUTPUT TESTS WITH ELECRAFT DL-1 DUMMY LOAD

MAY 5th , 2015

Elecraft DL-1 Dummy Load formula:
P(watts) = (V + 0.25)2 /25 where V= volts and 0.25 is the RF voltage drop across the diode

The following tests were done with the following QRP frequency XTALs:

- 7.030 MHz

10.114 MHz

14.060 MHz

The variable tuning cap was tuned to obtain minimum , midrange and maximum frequencies

Emitter Resistor at minimum - 39 Ohms  (maximum collector current)

SUPPLY VOLTAGE FREQUENCY MHz

  It is easy running a KW and talking around the world.  Even 100 Watts will  give you great results.  However, what's even more fun is that you CAN  do  the same with 10 Watts or less!  I have nothing against QRO operators. I work them all the time! Your probably a QRO operator reading this and we have made a contact. Nothing against your  "Fire In The Wire".  I just dont agree with the slogan "Life's too short for QRP".  QRP is lots of fun. Try it! Lifes too short not to try it.

REALITY!  WE WILL ALL DIE ONE DAY AND DONT KNOW WHEN!
