A U.S. Manufacturer of Repeater and Interoperability Controllers and Accessories
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:
-- new Runtime Variables (RTVs) have been added so that your messages can speak the current values of booleans, software switches, counters, timers, analog inputs, logic inputs and logic outputs.
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.
So where did it come from, anyway?
Not surprisingly, early repeater control systems weren’t very sophisticated by today’s standards. Oldsters will recall one-tube COR circuits, CW identifiers that used code wheels and tape decks, and controllers made from relays and pneumatic timers. Some repeaters could be shut down by dialing an unlisted telephone number.
The 7330’s internal power supply is compatible with both standard and alternative energy sources. Here’s how it works.
The 7330’s circuitry requires four voltages: +5 V, +3.3 V, +2.5 V, and +1.2 V. A type of DC/DC converter called a buck regulator reduces the external supply voltage to +5 V; linear regulators further reduce +5 V to the other voltages.
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.
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).
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.
We've just added another example to our FAQs and Programming Page. This one was submitted by an owner and describes how to get a scheduler setpoint working.
How do I figure out why my Scheduler Setpoint Macro doesn't work?
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.
