Here's a long test message created with Mike, N2HTT's program. Still
using the mary had a little lamb poem for the keys so even manual

Gentlemen,
In order to decode these messages, you must first download the Message Encryption Techniques for Field Agents from the Bayou Jumper Yahoo group files section, read and understand it or you'll never get it.  

If you can't access that file, you're going to be lost unless you download and install Mike Aiello N2HTT's Python program - _rebecca.zip from the files section as well and either get Python running on Windows (it's out there and runs quite well on the Windows platform) or if you're running Linux, you should already be familiar with the Python language and it may be even easier.  All the messages we are generating so far are using the Poem Code "Mary had a little lamb" as spelled out in the Encryption Techniques PDF file and unless a different poem is specified, that will always be the key generator.

Re: EZ Keyer III

Sam Neal
 

Hello David,

I also have a hearing problem and over the years I have been turning the
volume ever higher. I solved the problem by feeding the output from my Icom
756PROII through a Clear Speech DSP speaker - and then I feed it into a 50
Watt tube type Peavy guitar amplifier. The side-tone is still lacking.

I use a Pal-Star keyer. It can key three rigs at the same time if you should
want to. I use the solid state keyer output to key an old MFJ code practice
oscillator which is fed into a different input on the Peavy amplifier, leaving
two relay keyed outputs to key different tube rigs, one of which is in
stand-by position..

To say that the audio is full is an understatement. Of course, it is never ran
at full output - just a comfortable listening level.

73,

Sam Neal N5AF

Subject: [4sqrp] EZ Keyer III

Some have been known to say that I am losing my hearing (depends on who you
ask). Anyway, I got my EZ Keyer III out to tinker with and maybe program some
of the files to use with my Bayou Jumper, and also see if it would function as
a side tone. At first I thought the battery was dead but with more tinkering
and holding it up to my ear I could hear that the little piezo speaker was
putting out sound..... But not much. My wife could hear it up stairs and
wondered what the racket was.

Rest of story: today I received the larger Piezo speaker from DigiKey, the
one mentioned in the build instructions. Well, now I have a keyer I can hear!
There is a volume control inside the keyer but I have it turned up as high as
it will go. Now to replace the IRF510 in the voltage reverse protection
circuit and get back on the air. Neat little keyer.

So, if you are looking for a side tone AND a keyer for the BJ try the EZ Keyer
III. I think you will be satisfied. The built in key in the BJ is "cute" but
not comfortable to use and without the side tone how do I know how many
mistakes I am making?

Re: Long Test Message for you to play with

Jim Sheldon
 

Messages can be over 100 characters.  This is an exercise in how to handle columns that are longer than 5 characters The  short columns were covered in Mark's first message.  The basic rules apply.  The number of columns = the number of letters in the decoded indicator group words. The number of total squares = the number of characters in the message. When laying out the squares,  they go under each numbered letter in the key line.  When you get to the end of the key line, start another line of squares.  Keep adding rows of squares using that format until you have squares enough to hold all the characters in the message.  If the last horizontal row of squares contains fewer squares than the line above, blank out the unused squares in that row.  The columns above those blank squares will be shorter than the others.

Column 1 gets group 1 and however many characters are in group 2 that will fit.  If more than group 2 fits, keep going with group 3.  If less than group 2, carry the leftover characters into the column numbered 3 and so on.  That's how you handle big messages.  The only reason for the approximately 100 character limit was to make it difficult for a cryptanalyst to break the message.  Since we aren't really worried about that, the 100 char. limit is only for ease of decoding.  I made this one harder as a training exercise to see if anyone would tackle it and come up with a solution.

Re: Failed IRF510 in BJ

I had a problem with Q6 right after I powered my radio up. Got it fixed then a couple of days ago Q4 started smoking and

I'm pretty sure it burned up my whole radio. some of the etchings are fried, and nothing works now.


 

Burned my fingers on the reverse polarity IRF510. Rig was drawing 2.4 amps! Replaced it with junk box spare and all ok. Must be a QC issue with supplier.

Re: Pixie success

Sam Neal
 

Hello Curt,

I just got two new QRP(p) rigs. One is a Pixie with the crystal that comes
with it. Later I will switch it out for a 7122 crystal. The other rig is a
Frog Sounds transceiver. I hope it sounds better than a bullfrog! hi.

I am in Cleveland plus about 12 miles East near Romayor and am very active on
QRP/QRPp. We are probably 60 miles apart as the crow flies.

I would like to work you, Pixie to Pixie to get an idea how my rig may sound
on the other end. I haven't hooked either of them up yet but will and also
check the output power on one of my two factory built/calibrated Oak Hills
Research WM-2 QRPp Watt-meters.

I am retired and largely confined to home - so I can meet you on the air
almost any time that is convenient with you.

If this is OK, let me know when would be a good time for you. I still need to
make up a couple of power cords and find a key with a 1/8 inch plug on it.
Also need to confirm output power. I have a J-38 with one but need to uncover
it first.

73,

Sam Neal N5AF

Just to prime the pump a bit on the huffduff (HF DF) activity at OzarkCon, I've posted in the Files area of this Group a one-page PDF document showing how I cobbled together a small loop on the kitchen counter in about 10 minutes. Note that this is not (yet) a shielded loop.

It has a very sharp resonance that can be found by peaking the noise It does show directivity, but not much on 40 m right now to test with. On 30 m it was clear there was directivity. Being a very small loop it's not very efficient so signals (and external noise) are way down. It was also apparent that the noise at this QTH was directional

Voltage 13.5 v, current 430 ma when the BJ is turned on OR off.  Flickers a little up or down when first turned on.  No wonder the IRF510 heats the shack and takes down my SLA JetSki battery over night.  2 amp fuse in line with the positive lead to the BJ.   Originally the BJ was run on a battery but today did the tests with my Astron PS.

Very likely not a "dead short" failure. The gate structure isn't suposed to pass current at all, so even if it's compromised it may end up being a "lower" resistance path. To make a non-heatsinked TO-220 really hot doesn't take much current. The IRF510 junction-to-ambient thermal resistance is spec'ed at 62 deg C per W. So a couple watts gets you better than a 100 dec C rise. And 2 W at 12 V is just 170 mA or so. That would be some 4 amp-hr per day drained from your battery.

Now, that doesn't take into account heat that is transferred away via the soldered pins, but even if that reduced the temperature rise by a factor of 10, you could get a 50 deg C rise above ambient (90 F - pretty hot to touch) with 8 W. That would be less than 700 mA and wouldn't blow the 1 A fuse.

It would be an interesting and useful interesting data point if you could do a quick measurement of that current before you make the repairs, just to test the above theory.

In normal operation the voltage drop, Source to Drain, is so small with the device fully turned on that the power dissipation is very small as well. With an on-resistance of less than half an ohm, the 750 mA Tx current will cause less than 0.4V drop, and dissipate less than 300 mW. And, in theory, there's no current at all Gate to Source.
