• 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.

people are probably sick of seeing my name. Sorry if I ask to many questions. radios have been some what of a hobby for me in the last couple of months. Anyway, I have the beofeng its A great little radio. I like it but...... its not digital. I live in Arizona Maricopa county. almost everything is on digital now a days it really sucks. So I got to hunting around for a cheap digital radio and found this guy. SainSonic FM-416S dPMR .it comes with its own software and cable. Most importantly its not noticeable. it does not have the programing keys. Which leads me to my first question. how do you know what channel you are on. I don't see a digital screen. since it comes with its own cable I don't need any questions referring to the programming. Does anyone have one of these guys? are they good will they hold up at work? I am a maintenance person. I have dropped my beofang and it mess up the radio button when I dropped it but it didn't mess up any thing else. Thanks for every ones time for reading this post.

That radio will not do you any good for Maricopa County. Their digital systems are mostly P25 and DMR, which the FM-416S does neither. That radio is meant for the European market.

Radios in the past did not have screens. You had to know what channels were what. A lot of people taped a paper on the front or back of the radio to keep track of what channels were what. Typically, a radio without a display is limited to 16 channels, but some have upwards of 32 or 48 with the use of a zone (AB or ABC) switch.

Maricopa County has several simulcast, P25 systems. Bad news for scanner folks. Worse yet is the number of Talkgroups that are encrypted in Phoenix. There's still plenty to listen to--but it will cost quite a bit more than $50. Simulcast systems are hard to monitor because they have several towers that broadcast the same signal and scanners get confused can't figure out how to decode them.

Here's a kinda simple explanation of what happens. Radio signals travel at the speed of light (186,000 miles per second). Dispatch presses their transmit button and a signal is sent either through wires or microwaves to towers A, B, and C--and since they are not the same distance from dispatch each tower receives the signal a fraction of a second apart. The three towers then broadcast the signal over the air--and since they are not the same distance from you, the signals arrive at different times. Your listening spot, for an example, is 2 miles from tower A, 5 miles from tower B, and 8 miles from tower C. The radios that public services folks use are priced in the thousands, like $3-5 range. They are designed to handle simulcast systems. Scanners, not so much. You can try dumbing down the antenna (use a VHF instead of an 800), or a Yagi pointed at one tower--but there are several trunking systems with their own towers in your area as well as simple repeaters.

A decent scanner, which is what you require, is going to cost you around $500-600. Best option, visit the Ham Radio Outlet store, 10613 N 43rd Ave, Phoenix, AZ so you can try before you buy. Listen to several models side-by-side so you can see if they are dropping calls or not.

I tested with two Uniden BCD-536HPs, HP-1, and a BCD-436HP and there was no rhyme or reason to it. Scanner A would receive a call while B, C, and D didn't--then B would, then D, all the while C was dead as a post. I changed antennas and moved location in the house to get the best I can--which is still not all that good. I finally bought a used Motorola XTS-5000 and set it up for receive only (not a task for the faint of heart--high level of radio shop skills required and I was lucky enough to get hooked up by one of them).

UV-5R is analog FM only. Digital refers to digital modulation, like DMR or P25.
