• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

VXR-7000 DSUB Channel Control

Out club has a VXR-7000 connected to an Arcom RC-210 controller. I have a macro set up for a power failure that changes the courtesy tone to let us know there has been a power failure, but we’d also like to reduce repeater power automatically to extend our runtime (we lasted about 2 and a half days at full power on two deep cycle batteries.. not bad, but with minimal use.. more batteries and a solar system on the way soon)

Ch 1 and 2 are set up the same, with Ch 2 being low power and Ch 1 being high power. However in Remote mode I know you cannot change the channel from the front panel. Pins 16-19 are channel control. Pulling Pin 19 to Ground would effectively change from Ch 1 to Ch 2 (in theory without needing 16-18 connected as they all stay high) but I do not know if that still works when in remote mode.

Does anyone know if the rear channel pins will work as intended while in Remote mode and this will work? I wanted to ask before I start wiring and programming the controller for it.

The only thing I'm familiar with is the Power dropped to 10W on DC, but I'll look.
CE27 for Windows
Common -> Radio Status -> DC TX Power Low = enabled

edit: It's channel steering only on pins 16-19. If you're running DC only the option above wouldn't work, but you could use a relay drop-out to steer to ch2.
Not a great idea, but you use a relay to switch the low power button on the front panel. I'm not familiar with your controller, but maybe an I/O of DC and momentary latch there?
