• 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.

I have an Astro VLS-25M power supply that has fried a resistor on the board. It is the R14 resistor and I cannot find a schematic of that board. I found one for the RS-35 PS and it shows an R14 resitor to be 330 ohms in value. Can anyone assist me on this?? Either a schematic or verify what the value of that resitor is? I have called Astron, but no answers the phone.

Also the LM723 chips seem to fail and where can I get one of those if needed?

thx,

Mike

Someone picked up at Astron.......560 ohms and 1/2 watt rating. And IC can be had from digikey. Evidently this is a common problem with some Astron power supplies so just FYI if your PS show low voltage....most likely problem.
