What’s New

Version 12.2.3

This update adds some new tools and improvements:

■ Stock / Inventory

The Make section now contains a new Stock / Inventory tool which can be used to maintain your local component Inventory.

■ SamacSys / ECAD Models

I am very proud to announce the new ECAD Models Tool which is powered by SamacSys. SamacSys is leader in providing Schematic Symbols, PCB Footprint and 3D models for almost any available component.

You can now use the ECAD Models Tool whenever you are looking for Details, including Datasheet or Pinout for any component.

■ Source Code for Projects

You can now even add and edit the Source-Code files for your projects.

■ New Two-Tone Tool

Even though not just dealing with plain Two Tones, this new Tool allows to generate audio codes of a variety of different standards like CTCSS, DTMF, SelCall etc. There are already 11 different Standards supported. Let me know if you need more. I am happy to add them via Data Update.

■ Other changes

As usual, some additional minor requests have been implemented and some bugs were fixed.

Thank you so much for your support.

Please let others know if you like this App to keep it going.

Thank you so much!

Best Regards,

Electronics and RF Tools

WOW....... After a 30 year break I decided to get back into Ham Radio and Electronics I stated in Boy scouts. Needless to say my math skills were never great and now pretty much gone, my military service took its toll.

A few years ago I looked for this type of software but nothing like these were available, but tonight I found these two sets of tools and about hit the floor when I opened them, for me and others without an EE degree these tools include everything I need to not only troubleshoot equipment but now I think I’ll be able to build my own.

I cannot say enough good things about these, check them out you won’t be sorry. Now if someone could develop programming tools for ATMELs and PICs I’ll be in heaven.

Thank you for developing these awesome apps.

Second to none

I'm a lifetime electronics technician and can testify this is what gets you going in the right direction for most of your formula needs. I appreciate that the developer continues to support the app for well over a year since I bought it. Bugs squashed before I knew it was a problem.

A real electronic toolbox

What a nice professional product. I use this app weekly, saves time from not getting on a workstation just to design or validate a simple circuit.
Both RF-Toolbox Pro and Electronic TB Pro have been excellent references, and are always being improved/updated by Marcus. Thank you.
