7330 Radio Port to Yaesu DR-1X Repeater

The Yaesu DR-1X is a multimode repeater that supports analog voice and digital voice.

The 7330 can add functionality to the DR-1X in several ways:

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.

7330 ScriptKit Available

The 7330 Script Kit can be used as a starting point for configuring the ports of a 7330 with various Port Personalities.  I currently have examples posted for a Repeater, a Wired Link (e.g. EchoLink, IRLP, Allstar, another controller) and a Control Receiver.  You can find the Script Kit and its contents here:
 

New 7330 Programming Example: Final ID without CTCSS

This week I was asked how to configure a repeater to ID without a final CTCSS.  This programming example is one way to implement this solution.

S-COM 7330 and the Yaesu DR-1X

At Dayton, some of you may have noticed an S-COM 7330 mounted in a rack in the Yaesu booth between two Yaesu DR-1 System Fusion repeaters.  This demonstration showed how an S-COM 7330 can provide analog linking between two DR-1's as well as with other analog linking and repeater equipment.

7330 Programming Examples

There's a growing list of 7330 programming examples available now from the link in the menu on the left side of every page.  Customers like you have asked for these examples.  What would you like to do that you haven't gotten around to figuring out yet?  Let us know.  All contributions welcome.

S-COM Services What It Sells!

Every 5K, 6K, 7K or accessory ever sold by S-COM can be serviced by the factory! If you need service, documentation, or upgrades contact us!

S-COM In The News

The S-COM 7330 is shown in the May 2012 issue Mission Critical Communications, page 36, in a product roundup called What's New: Interoperability.  If you receive the magazine and have that issue, be sure to take a look.

Updated 7330 Speech Library Available!

This updated Speech Library, SpLibEng_1.2, shortens the words in the library by trimming ~5% of quiet from each word. Overall, this has the effect of making sequences of words sound faster.  This library includes the changes from SpLibEng_1.1 which increased the amplitude of all words to full scale and fixed the pronunciation of "Joaquin".  This update replaces the 7xxx_words_1.0.bin that has been shipping in all previous releases.
