Gary,

Congratulations on your breakout BJ contacts. Good things take time.

Very much enjoyed your writing and the enthusiasm it clearly communicated.

Subject: Re: [4SQRP] Bayou Jumper kit

Propagation finally smiled upon me. Today I made my first ever contacts
with my recently completed BJ. The first one was with KB5ILL in Louisiana.
He was 599. I received a 559. George was running 100w to my approximately 
5w.  Next up was N0YJ in Kansas. We were 559 both ways. Bert was also
running a BJ. That was my first ever BJ to BJ contact! Same for Bert
as I recollect.  I had to endure loud SSB interference during both contacts
but luckily I was able to tune to the opposite side with a good result.
I did not start making contacts until I hooked up my 4SQRP tuner.
It's amazing how much difference that little black box made once I
got it all tuned up. 

I need to get some more crystal adapters so as to be able to use some
of the other frequencies in my collection. I really like the Cajun
crystal adaptors. That's an innovative concept. The 7030 crystal currently
comes out on 7028.2 and the 7122 is 7120.2. That's pretty far off of
the published frequencies. I'm going to try rubbering the crystals to
get them closer to 7030 and 7122. The wide nature of the receiver does
help to hear some stations that are not exactly on your frequency.
Reminds me of my Novice days when I only had two rocks. I would call long CQ's,
and then slowly tune the entire band for calls. 

Somewhere in the fray I believe I heard a KL1 or KL1G something or other.
Unfortunately the signal faded and SSB monkey chatter took over so I
cannot confirm.

I must congratulate 4SQRP for a very innovative and novel radio kit.
I enjoyed building and troubleshooting this rig. I learned a lot
in the process. I am very appreciative of everyone's efforts. Thanks
for all that you do to keep ham radio interesting. The payoff was after
I made that first contact. Interestingly, I did have an incomplete contact a half hour
or so before the first good ones. I guess my signal was being overwhelmed by
fading so we never got a legitimate two way for the log. That was another
N0 station.

Good luck to all with your BJ 40's. I look forward to making contacts with
you in the future.  Now all we need is the Souper Upper to make the Bayou Jumper
an even better rig. Emoji

Stay safe and warm.

Best regards,

Gary, K7EK

Hello Gary
Sorry for your troubles.
After you get the coil moved, look for the oblivious stuff, missed joint, part in the wrong hole etc.

Then run the numbers on the voltage chart in the manual.

I finished my kit but ran into problems with the receiver. All I get is Brother Stair's AM shortwave
broadcast blasting through. The audio becomes louder as I turn the Attenuator to the right. Regen does
nothing, nor does tuning. I must have goofed somewhere. I am going to remove the toroid and reinstall it
on the bottom vice the top of the board. Although it can go in either location, I found it very difficult
to adjust the turns spacing as installed. So I will step back, take a breath, and reinstall the toroid
on the bottom in a day or so. I've been a ham since 1967 and do not knowingly remember building and/or
using a regen type receiver. Now 54 years later I must digress and learn about them.. :-).

The transmitter on the other hand is quite amazing. It works very well and puts out a whopping signal.
I was quite amazed. I've been jumping between 7030 and 7122 calling CQ's from time to time while listening
on one of my big rigs. I'm getting responses and seeing posts on RBN with great signals, despite horrid
band conditions.

On a more positive note, I did manage to get the prescribed small wooden box at my local Hobby Lobby. It
was the last one. I was unsure whether or not the board would fit so I had to make a second trip with the
board to actually place it into the box. Bingo! Perfect. $9 and some change and I am all set. Now I just
need to get the receiver working.

Question:  Are additional crystal adaptor boards available? If so, from where and how much? I would like
to buy 5-6 more as I have a handful of additional crystals I'd like to use with the BJ 40.

Happy new year, and please stay safe...

Those were the two xtal sources I was thinking of. I remember only using 2 xtals with my para80set, so 2 may be enough for a novel fun rig.

Been a while since I recalled ceramic vxo, yes if a stash of useful resonators could be found, even a stand alone vxo kit would be interesting. Many apps would do well with 20 some kHz of tuning.

Heard you with a nice skcc signal on 40m today but it was dinnertime.

Re: Cricket 40 Crystal Source

Bobby Drummond
 


Also, once you've used your Cricket for a while consider using a ceramic resonator (or better yet, two in parallel) along with a 22 uh inductor and variable capacitor in place of the crystal.  That would be a VXO that would allow you to use the Cricket in just about any part of the CW portion of the 40 meter band if you were to select a ceramic resonator in the neighborhood of around 7.2 MHz or so.

Yes, it would require some relatively extensive modifications to the Cricket but it's doable and would allow you much more flexibility with the Cricket.  With a little creativity and effort, you will be greatly rewarded.   (Kit designers of 4State QRP kits- please consider making some future simple transmitters using VXOs and ceramic resonators. I think there would be enough interest that it would be worth the effort)

For info about VXOs with ceramic resonators, just use a search engine and put in "VXO using ceramic resonator" and you should find plenty of information.

Glen. As I recently quoted to a valiant 4SQRP kit builder on the Bayou Jumper sub-Reflector:

“The credit belongs to the man who is actually in the arena. Who’s face is marred by dust and sweat and blood. Who knows the great enthusiasm, the great devotion. Who spends himself in a worthy cause. Who in the end at best knows the triumph of high achievement and at worst fails while doing greatly. So that his face shall never be among those cold and timid souls who know neither victory nor defeat.” Theodore Roosevelt

Disregard the “cold ... souls” reference in the quote. I suppose that, in your case, “Freeze My Butt, Off,” at least equals being “marred by dust and sweat and blood”. Congratulations, well done and to use another T.R., “Bully for you!” (and for and to all of those QRP Types who venture out there “in a worthy cause.”

Re: Anyone have a box for the Tracer Injector v2 Kit

 

Phil,

Ok, I see that the depth of the cast must accommodate a 13.4mm tall cap, but it can be taller and the board mounted on standoffs (unless one can find such a shallow case as 13.4 mm)

I didn't see what length and width is needed for `the circuit board to fit inside the case.

I bought a box of Bud and similar cases at a hamfest (back before COVID shut 'em down) and they vary in sizes from the smallest, 65mmx40mm & 27mm deep on up to larger sizes.  Also I have the larger size Altoids tin which is 90x55mm & 18mm deep.  What is the size of the circuit board?

Hi EuGene,

I'm rounding to nearest 0.1 mm, I'm using calipers that claim 0.01mm accuracy.

Top of board to the bottom of approx solder connection on the bottom of the board ~ 3.7mm

The top of the board is far more complex. There's a slider on/off switch, two connection ports to plug the probes into, the vertical caps are taller than the case of the volume control.

Board thickness ~ 1.6mm

bottom of board to top of stereo socket case ~ same as top of on/off switch case: ~8.4mm

bottom of board to top of tallest vertical cap (10uf) ~ 13.4mm

Probe ports, bottom of board to top of these: ~ 14.3mm,
  bottom of board to wide section of probe ports: ~9.7mm
NOTE: the probes should be able to plug into these to touch the top of the wide section.
DIA of the ports 10.8mm (10.82mm)

Bottom of board to top of volume control case: ~10.0mm (9.95mm)

Bottom of board to top of volume control stem: ~22.3mm (22.26mm)

If this stem is 22mm tall and the case is made to just match the height of the tallest vertical caps there's about 22-13.4mm ~ 8.6mm for a knob to slip onto the stem. Looks good.

However, if the case has to clear the tallest caps at 13.4mm then they are taller than the stem of the on/off slider switch and an extender will need to be made for the on/off switch stem.

Top of tallest cap ~ 13.4mm, top of slider stem to bottom of the board: ~12.6mm.

        _______Parts here - top of the board
Board:  |______solder + parts wires down below here - bottom of board

I hope that helps and is not too confusing.
