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)
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.

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.
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.
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.
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.
I purchased this radio in late October 2017. I live about 8 miles from the Boston UHF DMR repeater. I can hit the repeater from inside my house (my home elevation is about 8 feet above sea level. I can hit the this repeater from inside my vehicle on my daily commute into Boston - without using an external antenna. The range is excellent. I get good signal reports using this radio. The radio feels very solid in your hand. It is very easy to program. The programming software is very straightforward. I am a huge fan. I also comment Connect Systems for their customer service. I had a question about programming software. They responded to my email that I sent on a Sunday within hours. My experience has been so positive that I will purchase a CS-800D sometime in the next few months. I highly recommend this hand held unit and Connect Systems.
A terrific radio, great audio, good signal reports both analog and digital. Well made. The display is easy to read. At first the programming instructions were unclear but once you become familiar with DMR terminology, it makes sense.
I purchased the CS-750 on a friends recommendation for Amateur Radio DMR and I am pleased with this radio. I had my local Code Plug programmed into the radio and it works very well except on one item. The PTT Button has to be pushed in a certain way to ensure that I am actually transmitting. The housing is solid and it fits great into my hand. The display is big enough and the backlight works well, even when a receiving station is transmitting (where I can see the station callsign). This is a good starter radio for someone looking to get into DMR and not pay a high price. It also is not a "cheap" radio in its construction. The battery life is excellent to especially on low-power.
This radio does a lot. I will have to study the manual to learn. Has great sound and this radio is the best compared to D-Star and Icom. A great radio for the money.
Solidly built radio and the price is reasonable. Easy to use and the programming software is easy to figure out as well. Wish I had bought this radio a long time ago.
