According to this TI page uA733 14PDIP is active and there is a
list of suppliers and how much who has in stock:
http://focus.ti.com/docs/prod/folders/print/ua733.html

I am working on a new Ronja receiver that is called Mundaka and will
not use NE592. It should also have higher signal and ambient dynamic
range, higher sensitivity, better shielding, and logarithmic
ambient light and RSSI indicators.

Karel,

 

According to the site they no longer manufacture it but some seem to be still in stock, I hope to be able to get one.

 

Also can u please provide me with detailed info about the new mundaka, im on going to start working on a 100M ronja yet i want to see the 10M working first, so i would gladly help in developing the Mundaka

 

Ahmad.

Active means no more manufactured but still in stock? I thought
it means that it's manufactured.

http://ronja.twibright.com/technotes/mundaka.php

I can't imagine a way of help now. The work that has to be done is
all on the one physical prototype that I have at home and building
another one is relatively a lot of work because it's partially SMD airwire with tight parasitic inductance requirements.  
Special purpose-built scope probes have to be used, shielding and filtering is critical.

So if I got u right,, the design is complete but the problems are in the implementation only? I should give it a try then, and anyway any prototype would be built with air wires before pcb implementaion, if only air wires are the problem then that can be overcome. But why cant the regular scope probs be used?

 

 

A last thig, will u please arrange ure technotes site better than it is now, why dont u make it that when u go to the page u find a list of all possible technotes instead of the current design that doesnt show what are the currently available technotes?

No the design is not complete and there are no problems in implementation.

The regular scope probes have too much load capacitance and too much
parasitic inductance on the ground lead.

Really??? its the first time I know that coaxial got that much capactiance and inductunce... so what is the followed procedure to reduce that?

Hi,

 

How did simulate the Rx, Tx? does the Eagle have HSDL and in its library or did u creat and equivalent circuit / model?

What did you use as an input instead of the SFH?

When placing capcitors does it matter in the simulation which C is SMD and which is ceramic?

All simulation is done by Gnucap. I didn't simulate the TX so
I didn't need a model for HSDL.

Current source and a capacitor.

Yes that matters. See http://ronja.twibright.com/technotes/stray.php

Message-ID: <28732289.1244572779210.JavaMail.root@viefep14>

I just started using 96-well laboratory test plates for organizing my SMD resistors and capacitors.
http://www.tpp.ch/tissue_culture/test_plates/Test_plates.html

 Their horizontal dimension 12 exactly fits the E12 number series:
http://en.wikipedia.org/wiki/Preferred_number

The vertical dimension fits 8 decades, 1 Ohm
- 82 MOhm, 1pF-82uF.

There is loose lid which has ridges preventing the components from
falling into neigbouring well when the thing is turned around with
a slightly loose lid. I use rubber bands to secure the lids.

Now I can organize all my SMD R's and C's just in two little
plastic boxes!

Hi again,

 

One more thing,, in ICs like 74AC04 for instance, how can I set there Vcc values? shall I do that through the model editor? do u have experience with that?

Am working on Orcad 10.3 and would go to 16 in few days I hope.

 

Regards,

Ahmad

I have no experience with modelling in Orcad.

Any one know how to built this TX (or what mod) for laser pointer?
