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.

My vote is also to ressurect the
Soup'er Up'er now that the BJ is back. It would greatly enhance the rig and the wheel would not have to be reinvented.

I have the original white faced BJ which works extremely well. Nevertheless a filter would be helpful. My Hi-Per-Mite should arrive today or tomorrow. I plan on trying it as an external addition first. If that works, I have a plan for putting it in the BJ wooden suitcase. I can let you know how it goes.

I wonder if most people build the filter in to the unit or use it as an external addon. That would have the advantage of being used with other rigs. I'm leaning toward building it into the rig and just adding a switch.

I'm in favor of bringing back a version of the Soup'er Up'er as well!

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,
Gary

Here's a pic of mine. I mounted it in a box which is angled, the back being higher than the front. I think it was designed to be used in this manner. In the pic you can see a crystal in the crystal oscillator socket and the frequency counter reading the crystal's frequency. All the connectors for the different functions are on the back along with a 9V battery mounted externally. Building the test set this way makes it very handy & easy to use.

I don't know if you've ever seen mine or not, but I made it a lot more
user-friendly by putting it in a box and using a multi-position rotary
switch to choose the different functions.  I really like using it to
test crystals with the crystal oscillator and frequency counter.

For what is a crystal spotter used?

Jim, N5IB
 

A crystal spotter is just a simple oscillator which will emit a very low level signal when a crystal is attached. It's used to locate the crystal's operating frequency in a receiver, when the receiver is not slaved to the same oscillator as its companion transmitter.

It's very useful with the Bayou Jumper, which has a wide pass band regenerative receiver, completely independent of the transmitter. If you're calling CQ with a Bayou Jumper you need to know where on the receiver dial to look for replies, since most operators using modern VFO controlled transceivers will zero beat your signal. It also helps to find out if there is other activity on your crystal frequency so you won't QRM them.

The spotter does not have to be connected to the receiver, just placed nearby. Enough signal leaks out to be easily heard.

BTW - whenever you are the "other op" trying to call and work a Bayou Jumper, remember that poor fellow has a regen. It's wide as a barn door, very sensitive, but he has to manually throw a switch and then perhaps tweak the tuning a bit to get back to where he was.
