• 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.

Was always curious about this.

I come to visit my mom in Los Angeles from Arizona regularly, and always have to pass the CHP/Caltrans office in Glendale. I’ve always wondered why this vertical beam antenna is on the top of this tower, and what band would it be used on? I finally decided to park across the street and take a picture. I’m pretty sure that they’re not shooting skip on CB Channel 6!

When I worked for Minnesota DOT, we had a short wave installation at our main Highway Patrol dispatch center that communicated with FEMA in Battle Creek, MI. Our antenna was a multi band trap dipole. Usually we used something like 7.8 MHz SSB to communicate with FEMA. But there were a suite of frequencies just above the ham bands up the spectrum if we couldn't communicate on 7.8 MHZ.

My first guess is they use a something above 14 MHZ for the same.
OR second guess: some of the radio techs are hams and put a beam on the cat bird's seat of the state's tower!

Ham Radio. There is a weekly net of various state offices, including Caltrans, CHP, State Hospitals etc. There was one on the CHP/Caltrans building in Fontana before it was destroyed by winds.

I pass by there on my daily commute along the SR-2 Freeway. Kind of a stealthy looking building with the tinted windows and such.

The HF antenna is most likely for the SHARES (SHAred RESources (SHARES) High Frequency (HF) Radio Program | CISA) radio system. @mmckenna most likely can elaborate since he works directly with this equipment at another location.

Thanks for everyone’s response. Makes more sense know, and obviously I made a mistake. That’s a horizontal beam. 😄
