A New Jersey Battalion for the CBLA? The NJQRP SNAP on 3.579

Back in 2000, the NJQRP club came up with a nice little transmitter called the SNAP. It was designed by Chuck Adams K7QO.   Dave K5YFO alerted us to it and suggested it as an alternative to the Mighty Midget.  One advantage over the MMM is that the SNAP needs no variable capacitor.  But it does need a couple of coils wound on toroids.   The SNAP design includes a low pass filter, something that has to be added on to the MMM.  Check it out.   Even if you've already built the MMM, you could easily take the crystal and use it in a SNAP build.

Midwest Mighty Mite from KK0S

Wow, beautiful job Bruce.  I was hoping that a check of the Reverse Beacon Network would reveal that someone had heard you, but no joy.  Keep at it.  You may become the first CLA member in this round to make a contact.  

Bill - 

Hello from the Midwest chapter of the CLA.  Here's pix of my just completed Michigan Mighty Mite.  Nothing was purchased specifically for this project.  It was put together using only parts already on hand.  The only previously unused parts were the front panel sockets and one resistor.  The rig uses a 2N2219A transistor salvaged from a junked industrial control board and a color burst crystal that actually first oscillated in a tube-type color TV some 40 years ago.  Loading into my ground-mounted vertical, this MMM seems to be most stable at a draw of 87ma at 12.6 volts.  The arithmetic seems to work out at somewhere around 650mw into the ether.  I called for about half an hour around 2300Z, but got no takers... it was still pretty early for 80m and I had an extremely high local noise level.  The rig seems to run about 1khz high. I'll give it another go this weekend.

Jean Shepherd's Shack Gets Hit by Lightning

Yikes!  This is really good!  Thanks to Harv for sending us this link:  Poor Shep!

Greetings Bill,

Have been loving each Soldersmoke Podcast and Blog Segment recently.
You and Pete have made the program a superb treat while I've been busy with the Radio Room construction.


Building the Radio Room is like constructing an ARK in your Basement. Everything is being done in pairs
and the water keeps rising. (No kidding)...
I encountered two water breaks in the Radio Room while construction was under way but, that is a whole different story.
Fortunately none of my prized boat anchors were damaged.

The project; (The Radio Room), includes operating positions for 14 complete stations.
That wouldn't be too bad except I'm constructing walls, benches and over-head lighting from complete scratch.
While this is going on, I wanted to finish my 3.579 MHz CBLA transmitter and return to the Minima build that I started in April 2014.
However, in September, I retired and moved to another state.  The reality of the latter took awhile to sink in. Most Ham Projects took a back seat to higher priorities. I will soon have the Radio Room I always dreamed of. The Drake 2B fills the space with the sound of 20 Mtr CW and the anticipation of having the HT-37 brewing away is just around the bend.

I'm taking a short sabbatical from the Ham Shack construction to get caught up on some other household projects.
In this notion of taking a needed break, I rediscovered Jean Shepherd's programs on Youtube.
I started to dissect Sheps monologue when I found that familiar path in my own life as a 15 yr. old Ham in the mid-1960s.
I'm sure you too can relate to Jeans' life as a kid.
I really liked his broadcast https://www.youtube.com/watch?v=akyTVNorXQ8&feature=player_detailpage
"Lightning Hits the Ham Radio." Near the end of the program, he mentions that his life was over because his
Dad hammered him over the damage to the house by the lightning strike. I'd love to hear the rest of that story!!!

Please keep up the great efforts with Soldersmoke and bringing us all that good Tribal Knowledge. I think we should all go build something.
Looking forward to what's next. Thanks to You and Pete.

Mahalo! WH7TT's Hawaiian Mighty Mite

This is our western-most MMM.  Edward took one of the 3.579 rocks and, using a Radio Shack breadboard (much used by Michael Rainey AA1TJ) built his version of the Mighty Mite.  When I saw the long clip leads to the coil I was apprehensive, but obviously it works.  Great job Edward and thanks for sharing with us your island rig.  Mahalo! (I like saying that!)

W1KF's Connecticut Mighty Mite

Steve W1KF's Connecticut Mighty Mite is the neatest build so far:   it has a front panel and knobs and plugs and everything!  Pete Juliano commented: "Very cool –and elegant. I loved the transistor in a front panel mounted socket with heat sink. Wished I had thought  of that –great idea."  Steve is on the air at grey line times, looking for contacts at 3.579 Mhz.

Launch of the new Orion rocket

The Saturn V was, of course, far more impressive and beautiful.  But the Orion is pretty cool. When  I was looking at the drawings depicting the various stages of the spacecraft,  that Apollo-shaped capsule brought back some deep memories.  I was 10 years old when Apollo 11 launched.

Manhattan Mighty Mite: "Rockin' the Big Apple on 3.579"

Dave W2DAB got his Manhattan Mighty Mite oscillating nicely!  Hooray!  

Check out Dave's report on his Mighty Mite adventure: 

http://w2dab.bamford.net/

So far we have sent out 20 colorburst crystals.  Already we have two circuits oscillating (not counting Pete's and mine). 

CLA is on the march! 

E-mail from Dave: 

Dear Bill & Pete:

Thanks for all your help, I can joyfully announce the birth of my first Michigan Mighty Mite, Oscillating at the frequency of 3.579!  Yes, Pete’s sage advice to flip the coil over was a great help and also my good friend from Vermont (A Michiganian by birth ).  OK, so Bill… you remember your most embarrassing moments in home-brew? Well, here’s mostly what happened: I was reading the article I found online and somehow got 40 meters stuck in my head even though your colorburst was for 80 - So I build a 40 meter coil.  When I realized my mistake I thought - well why not build two of these so I pulled out the Colorburst and put in a Norcal 7.040 and then built a new board with a new 80 coil oriented properly and the pic below is the one you see.  Now I have two Mighty Mite’s that work, how great is that.

My next goal is to continue forward using Pete’s Build Something Video’s, so more fun to come.

I will post a video on my blog of the 80 Meter Colorburst Michigan Mighty Mite uttering it’s joyful tones, but for now I’ve put a lovely photo at the bottom.

Success is sweet when you hear the sounds of the beep!

Cheers and 73 Gentlemen

Dave
