• 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.

DTR650 - Decent speaker/mic's for them?

We have a collection of DTR650 radios and are having a difficult time finding a good speaker mic for them.

There is a uniqueness on these DTR radios as the depth of the plug has to be extra deep since they need to accommodate the rubber seal on the mic/speaker jack. If it doesn't have the depth, it doesn't plug in, or if it does, it comes out (since the rubber seal folds over right underneath where the cable comes out).

The microphones motorola sell for this radio (HMN9026) are huge and the PTT is awful (hard find push).

Pryme makes one, but still has the issue with the jack not having the depth.

Anyone have the DTR650's with a quality speaker mic (that isn't the size of a truck)? :)

I'm using the hmn9026c on my DTR550's. The size is fine, but they don't go loud enough at all.
Anyone know if the HMN9051a is louder?
The connection looks the same as the CP series, are there any specs anywhere on these speaker/mics that lists DB levels?
