Bayou Jumpers plug in their 7122 rocks and try to work "London"
"London" has to tune all around 7122 to find those Jumpers in their  cute little QRP pileup.

Maybe "London" sends a unique BBC-style "message for our friends…" to each caller
  e.g. "Jean has a long mustache"   "the porridge is cold"  etc

Certificate or QSL to each agent who copies successfully.
Extra Spam ration coupon to "London" for the effort.
For more realism, "London" ought to be a YL

How many Bayou Jumpers could we get to congregate?
Could we find a way for those poor, Jumperless, QRPers to join in?

Re: For what is a crystal spotter used?

Jim, N5IB
 

The question asked was, "why not just power the Bayou Jumper's oscillator, but not the PA, and just listen for the signal in the receiver?"

The answer is - The Bayou Jumper does in fact work exactly that way. When you press the key while in the receive mode, the oscillator is activated, but not the PA. It was designed to do that. The signal can be heard in the receiver. Great, just what's needed, right ?!

Well, not so much....

Remember, the receiver is a regen. That means that any strong signal will pull the receiver onto the signal frequency. And remember that the source of that signal (many many millivolts) is right on the same PC board, just a few cm away from the detector. The zero beat "point" on the dial ends up being a broad region, with no some strong over a fair amount of dial in the middle and squeals on either side.

Now, if you run the regeneration control all the way to max, run the attenuation all the way to max attenuation, and turn the AF gain way down, you can sometimes just about get away with it. But then you have to reset everything back to normal receiving. Much simpler to have a little oscillator sitting next to the rig. Touch the crystal to it, and a clearly discernible, but not overly strong, signal can be heard. Tune to zero beat, pop the crystal back in the rig (maybe mark the dial) and you're ready to roll. You'll hear everything with three of four kHz of the zero beat point.

Bottom line, there's just not an easy way to knock down the signal strength of the internal oscillator to the point where it will play nice with a regen detector. BTW - the original Paraset couldn't spot it's own signal either. The B+ was switched off the receiver during transmit. But, they didn't have to. They knew where to listen for London (definitely QRO!) , and London knew what crystals they had.

BTW - When David designed the Soup'er Up'er he had to fight that problem to get a working sidetone. The audio amp had to still be powered during Tx, but he had to knock down the Rx output with a MOSFET switch.

Hi Everyone ....

A bit off-topic perhaps and i apologise to the group list moderators

Im asking here as i know some of you will have done this on occasion for yourself

Myself and my family tried to find out the current correct QRP ARCI officer and procedure again to purchase the dvd in the subject heading for christmas there

Alas this was to no avail with no answers to my sisters enquires to the toystore

I would very much still like to have the updated dvd I always have this same trouble each time we try to order this dvd

Perhaps its due to the fact i have a qth in Scotland - United Kingdom

And NOT The U.S.A or Canada ??

Can some help my family get the show on the road happenin with this for me by assistance somehow ?

Thankyou

Much Obliged !

Here's a 2m FM unit that you can try.  Although it's on my website I have never tried it myself....... I thought that some of the locals would enjoy practicing CW but it was a dead end.

Really not very complicated, no bells and whistles.  I probably have most all the parts if you don't and would share them.  You would need a box and some battery power, perhaps a 9V ?

Re: DMR Net

Unlike FM, with DMR you need to "ker-chunk" your radio when you select the appropriate talk group, to let "the system" know you wish to monitor that group.  Before that light bulb lit up in my feeble mind, I had the same experience.  I had no idea why I wasn't hearing anybody.

Re: For what is a crystal spotter used?

Hey guys,
I joined you group just to educate myself on another rig that's out there.
So, I don't really have a dog in this show but...

It seems to me that you could just make a simple mod to the Jumper, why do you need a whole
new gadget.
You just need to power the oscillator and cut power(or drive) to the final like all old novice type
transmitters did it.

If you take the crystal out of the FET Jumper oscillator and put it in an external bipoler oscillator,
are you sure its even going to be on the same frequency?  Ok, with a regen receiver a few KHz
isn't really going to matter.  Can't you just put a mark on the Rx dial where your crystal frequencies
are?  Even if its off a little, when you call CQ (the only practical way to get a contact I would think),
with the regen selectivity, you are going to hear them over the large passband, no?

As another little kit project, ok, I can see that it will be fun and a little educational, but...
Back to my hole,
73,
