• 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.
  • Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I haven't seen any posts about this product yet. The Retevis RT97 is a 10W duplex repeater with a pre-tuned duplexer in a weather resistant metal enclosure. It runs on 12V and sells for around $400 US. It can be ordered with a 5 MHz offset within the 420-450 MHz 70cm ham band. As such it should be useful as a low power ham repeater operating off of a single antenna. I don't think it is legal to use in the US for any other purpose as I can't find any FCC certification for it.
More information is available at the following websites.

This kills the deal unless you are on the left coast where folks use the reverse split on some UHF repeaters.

4, UHF-5Mhz-Customize: Offset 5mhz, Tx and Rx's frequencies can be customized. But Tx must be higher than Rx

Definitely an inconvenience. Of the 15 70cm repeaters near me, 10 have a -5 MHz and 5 have a +5 MHz offset. I suspect there are other limitations that are more serious.

I always attributed the weird California offset to the availability of many obsolete UHF MTS and IMTS phones that could be easily converted to a repeater but stuck with the TX high.

I always thought it was because the ex-commercial subscriber gear RX side wouldn't go too far out of band but the TX side would?
