A U.S. Manufacturer of Repeater and Interoperability Controllers and Accessories
See all DR-2X and DR-1X interface documentation here: http://www.scomcontrollers.com/yaesudr1x
[Update 11/18/2017] At S-COM, we've been testing the DR-2X with the S-COM 7330 repeater controllers. The DR-2X that I have has the external controller modification and the latest firmware.
Here's the two configurations that I have tested and work well:
Thanks for all the comments on my first post. Your feedback has been a big help in figuring out what features should be included in a new controller. Keep the ideas coming!
The worldwide supply chain shortage in integrated circuits has made it very difficult for most manufacturers to keep up with demand for products. Because of this shortage, we are forced to discontinue production of the 7330. It was a very good run (we've been producing them since 2007). We just can't buy the parts.
But we're still here. We're available for support of all S-COM products, Dave is working on firmware updates for the 7330, and there's also a new controller in the works. Stay tuned for more news from S-COM.
S-COM has not been directly affected by the COVID virus -- we're all healthy -- but we have been affected by supply chain issues regarding the availability of certain components used in our products. This is something that is affecting all manufacturers, even the car companies, because virtually all electronic components are now manufactured outside the United States. Be sure to contact us for product availability.
I've lately had an itch to write posts to a blog describing what's on my workbench to do with repeater controllers and repeater site infrastructure -- if I can tear myself away from the workbench long enough to write it ;-) I'll try to keep my blog posts on-topic and a quick read.
So, where to start.
Bob DeMattia, K1IW has contributed an article on interfacing a DR-1X and DR-2X to the 7330. This is the solution used to deploy these multimode repeaters across his club's network.
When building a custom audio library from individual words or phrases, it's useful to be able to quickly play those words from the raw files stored on your Windows PC instead of going through the entire process of building and downloading a custom audio library to the 7330 only to find it doesn't work. The way most of us play a custom word on Windows is to run Audacity, import the file, then play it. (See 7330 manual page 23-13.)
It can be even simpler to play a word with SoX. (See page 23-11.) Normally, SoX is invoked at the Windows command line with the program name
Let's say we want a message to be appended to the Repeater Initial and Normal ID Messages while the repeater is operating on battery power. We have wired our Logic Input #4 to detect a power failure.
We program User Message #1 with the speech we want to hear, like this (see page 6-63):
; Say "power fail thirteen point two volts" or whatever the actual voltage is
99 33 0015 9960 0148 0766 9852 01 00 9960 0150 *
You can test this message with this command:
99 34 0015 *
Yahoo Groups is shutting down their current Groups service. Because of this, we have moved the S-COM lists to groups.io.
