Release 1.7 of the 7330 Firmware and Tools is now available! Our testers have finished their testing and all feedback has been incorporated into the firmware and documentation.

There are two new major features in this release:

Bob's Blog #5: Macros

Macro commands have been implemented in every S-COM controller since 1976. Why?

The term dates from mid-1950s computing. It was common for a programmer to enter a short macro instruction to generate a series of other instructions. It saved time, reduced errors, and helped standardize the code.

7330 GUI Programming Utility

Sigrid Company LLC is pleased to announce version 1.0 of P7330, our new GUI programming utility for the S-COM 7330 repeater controller.

P7330 includes these advanced features and more:

    • Message Builder - Create a messages without looking up controller codes.
    • Macro Editor - Create & manage macros with automatic creation codes and password insertion.
    • Macro Pick List - Shows currently defined macros. Drag & Drop a macro from the list to any macro field.

Bob's Blog #1: 7330 Digitally Stored Speech

Years ago, the S-COM 7K and similar controllers used voice synthesizers to create speech for talking clocks, talking calendars, announcements, and so on. Users could not add their own words to the vocabulary due to the specialized hardware and software involved, so we contracted with a language lab to offer a word creation service. EPROMs were programmed with word files from the lab and shipped to customers for installation in their 7K SSMs (Speech Synthesizer Modules).

7330 Speech Library Update Now Available

Yesterday I posted an updated to the 7330 Speech Library, V1.3.  This is an optional update that fixes the mispronunciation of the phrase "http://www.".  It also includes an improved version of the letter "S".  We have received several reports of "S" sounding like "F" in some cases and are making this fixed version of the letter "S" available.  

You can find the updated library file on the 7330 Firmware Upgrade page.

Q: How do I delay the PTT on a port after a power cycle?

After a power failure, some radios require that the PTT not be asserted for some amount of time.  You might need this if you have a tube power amplifier that needs to warm up, a Yaesu DR-1X that might lock up, or a Kenwood TKR-x50 Version 1 that switches modes.

This example uses a User Timer (see page 20-1) that is started by the Power-Up Macro (see page 5-28).  Macros disable the transmitter PTT (see page 11-26), then reenable it after the delay time.
