If you do not already have one, it is recommended you get a programming cable for $5.

If you want a single band DMR / Analog radio you have a choice between the CS750 or CS580. Comparing the two is like comparing the Rolls Royce against a Tesla. They are both great cars but the Rolls Royce won't accelerate to 60 mph is 3.9 seconds. In a like manner, the CS750 is one of the best made DMR radios made at any price but does not have a few features of the CS580. Even some of the Motorola Engineers prefer the CS750 over the Motorola XPR6550.

Can You Hear Me Now?
Some of the Motorola Engineers reported in the Yahoo Forums that the Hardware of the CS750 is 3dB more sensitive than their radio with the other parameters being about the same. One of our commercial customers was testing the radio in Las Vegas when it first came out against the Motorola radio and a Hytera radio and found that they were able to maintain communication at the fringes of reception with their repeater while the other two radios were silent.

How Rugged is the CS750?
The CS750 is among one of the most rugged radios available. We have had a customer accidentally drop the radio from 30 feet and the radio suffered no damage. We had one customer accidentally drop the radio from 50 feet and the only damage was the display which was replaced for $10. Most of the others radios will break and cannot be easily fixed if you look at them funny.

Will it Work in Sunlight?
The CS750 can be used in bright sunlight. The other radios displays fade in bright sunlight. This is a choice you have to make. While the CS580 and a few other radios have a multiline multicolor display, their display cannot be seen in bright sunlight. The CS750 has a two line single color display that can be used even in bright sunlight. The larger color display of the other radios make it easy to break when it falls.

Superheterodyne Receivers Verses Direct Conversion Receivers

The CS750 receiver is based on a tuned front end double conversion superheterodyne design. This gives the ultimate in sensitivity and selectivity. The cheaper radios are based on a single chip design that often fails in a high RF environment such as you might find if you go to a HAM convention. Because of the design of the PLL in the CS750, any birdies can be eliminated. Not so for the less expensive designs.

CS750 Verses Hacked Radios

Some of you might be comparing the CS750 with the less expensive hacked radio from one of our competitors. What the engineers who hacked the radio tried to do was add features that was already in the CS750. While they did a decent job, they still have not incorporated many of the features that has been in the CS750 for many years.

Have you ever tried to get support from some of our competitors. If you know Mandarin Chinese and you have free international calling you will have no problems. If you want to speak to someone who native and only language is English, you call Connect Systems during normal business hours. We also answer e-mails after hours and holidays. Here is what some of our customers say.

"Once emailed Connect Systems in the early morning hours east coast time. Knowing they were west coast and would not be open for hours I was surprised to get an email response from Jerry personally before they were even open." (From Facebook)

"I've always has good support from Connect Systems. Chris is amazing." (From Facebook)

Code Plugs
If you are hesitating to get this radio because your friend has one of our competitors, be aware that through the generous effort of Tom Wheeler, he made a conversion program called "Contact Manager" that converts virtually any manufactures code plug to the CS750. You can get that free program by following this link.

    Very Good DMR HT

    Posted by Dave on May 19th 2023

    I have owned several DMR HT's and that is an understatement. The CS750 is definitely my favorite. It has a very simplistic display and a CPS that is fairly easy to navigate. I hope the 751 comes back in stock because I will be ordering that as well since I really like the platform of these radios.

    CS750 Handheld

    Posted by Mason Sarles on May 10th 2023

    I have only had the radio for about a week. My friend Mike helped me build my first code plug. So far the radio has performed well, as expected. I would buy it again, and I would recommend. Best 73

    Still my favorite DMR radio years later.

    Posted by Andrew Camp on Mar 30th 2022

    I have owned this radio for a good handful of years now and it has yet to fail me. I use it at work during the day and at night I use it with my hotspot on the ham frequencies, both analog and digital work phenomenally. Enjoy your CS750!

    I started out with DMR in the beginning and my first DMR radio was a CS750. I sold that radio, along with many others including Hytera PD682, 2 Motorola XPR7550e over the last 5 to 6 years. Today, I’m down to one radio and it’s the CS750. Should have never sold the first one. It just meets my needs.

    CS750 Radio

    Posted by Barry Robinson on May 27th 2020

    I have switched my EH&S employees/responders to the CS750 and we find this to be a very good radio in size, sound and functionality. This is a quality made and rugged product yet an inexpensive replacement for the overpriced brand "M" 6000 series radio we used to carry. CSI is also user friendly to the programmer, by providing the CPS free of charge. Being it's a SuperHet design, I've not had any desense issues in an environment that is surrounded by steel walls and structures as well as numerous other radios TX'ing at the same time, like I've had with other Chicom direct conversion style radio's I've tried. I'm very pleased with the CS750.

    CS750 you won't find a better radio anyway

    Posted by John Hess on Jun 26th 2018

    So the story goes like this. I read a allot about DMR and wanted to give it a try. Since it was a new mode for me I didn't want to spend a bucket on it. I did allot of reading and saw many, many many radios out there. During my search I stumbled across a post that talked about a radio that had voice output. This is important because I am blind and can't see the screen. It was the CS580. I went to the companys website and was shocked to find the number of the president and his e-mail address listed. It was a Sunday and Well, why not take my questions to the top. I really didn't expect an answer. So, I e-mailed Jerry and to my surprise on a Sunday afternoon within an hour I got a reply. The conversation started and He told me about the radios he would recommend that offered some type of voice functionality. What won my respect was was how much he cared about his products and his customers. So, in the hopes I could continue receiving this excellent support I bought the 750. What came out of the box resembled a $500 radio not a $260 radio. The CS 750 looks like a well Built Motorola, solid, durable, great to hold and use. It connected to my computer instantly using the CPS software supplied on the CS website. The software is friendly to Screen readers used by the blind which made me more than happy. I could program this thing independently. So, I uploaded a code plug and with some help from Chris, yup, He's another of those great caring support fellows, got the layout of the keyboard and made a contact. Man, was that exciting. The audio is nice and loud and I was told my audio sounded good. I also bought a CS580 which I am looking forward to receiving. Conclusion: If you want a radio with the quality of the big guys and a price you can afford, by any of the connect systems radios. I doubt very much there is a company that will support you as well as Jerry and his crew. Thanks Jerry, it's really appreciated.

    This radio is very well built compared to my MD380. The case feels like you could drive nails with it. The firmware is very stable as well. Very easy to program from scratch or using Connect Management Software. No problem converting the MD380 code plug to the 750. So along with the solid construction and stable firmware, I think it's worth the price. Not to mention a USA based company that is only a phone call or email away to help you with any questions.

    Great value. Great radio. Initial sw revisions were a bit confusing. This was quickly cleared up by Chris. Recommend you build a sw and firmware packaging script that runs and checks compatibility of the software and firmware for the user. The package could update anything that was down revision for the user. Other than that this radio is a great value and I would not hesitate to recommend it to a friend.

    amazing radio for the price

    Posted by Charles Burnham on Jan 22nd 2018

    The radio was recommended by a friend. He programed it for me & I found it easy to operate. Thanks for making it for the amateur market. I will recommend it to my fellow ham radio operators.
