It’s not cheap, but the Icom IC-7100 has tons of amazing features and is built to last, making it a good overall investment. This is a great mobile transceiver, particularly for newer operators who may have mostly used HTs, but are now familiar with the basics and are ready to set up a home base station or a mobile vehicle station.

You may want to keep this in mind while shopping.

Touchscreen quality control – A handful of users have noted that they’ve experienced malfunctioning touchscreens or complete touchscreen failure.

Lacks a few features compared to the competition – Some comparable radios in this price range have features like a GPS, color screen, and built-in antenna tuner, which the IC-7100 lacks.

500+ memory channels – The IC-7100 supports 495 standard channels, 4 call channels, and 6 scan edge channels, as well as 900+ DR mode repeater channels for D-STAR users.

Powerful DSP for clear audio – The proprietary digital signal processing (DSP) uses a 32-bit, floating point architecture to provide clean, crisp audio on both digital and analog bands.

Paired with the proper antenna and accessories, this powerhouse will have you reaching repeaters and base stations worldwide.

Tri-band design with plenty of power – Maximum transmit power is up to 100W in HF bands, 50W in VHF, and 35W in UHF.

While it doesn’t come with a GPS, it can be expanded with a variety of compatible units for further functionality. It supports both DV mode digital voice and low speed data communications.

Excellent D-STAR capabilities – The IC-7100 is an excellent choice for any ham looking to dabble in digital radio.

And, despite its light weight, durable rubber feet keep it from moving around during routine use.

Intuitive detached control head – The angled control head may look a little bit funny at first, but it’s got great ergonomics.

It even functions while wearing gloves, which makes it ideal for use while working outdoors in cold conditions.

Great display with excellent touchscreen – It may not be full color, but the LCD touchscreen is large and responsive, making for an excellent user experience.But it justifies its price tag with robust features, excellent sound quality, and a surprisingly small learning curve, especially for those who have already used Icom products in the past. Pinouts change over time but using the right connector for the right cable will preserve the signal integrity and modular plug usability.A fully-featured tri-band radio that also offers amazing D-STAR compatibility? Who could say no? The Icom IC-7100 may be a little bit expensive, particularly for new ham operators. In the end the only difference between is that one is designed for shield cable the other for unshielded cable. After plugging and unplug devices the strain on the pin connectors will cause one or more pins to intermittently fail. However, doing this negates the shielding at a point where the signal would be the most vulnerable to interference.Ĭonversely if you have UTP cable and try to put it in an RJ48 connector the cable itself will be loose causing strain on the connectors. If you have STP cable trying to put it in a RJ45 connecter will be difficult as the shielding would have to be removed in order for the cable to fit in the connector. RJ45 is designed for UTP (Unshielded Twisted Pair) Cable (thinner) The difference is: RJ48 is designed for STP (Shielded Twisted Pair) Cable (thicker) RJ45/RJ48 uses 8 pins & 8 connectors - Yet not compatible. In simple terms: RJ45/RJ48 has their own "pinout" used to wire the modular plugs. RJ45 is connected with UTP cable while RJ48 uses STP.RJ45 is predominantly used in LAN while RJ48 is more commonly seen on T1 lines.RJ45 differs from RJ48 in the way they are wired.To protect the integrity of the signal, RJ48 wirings use STP or Shielded Twisted Pair cables. RJ48 is used in T1 data lines where the wires can extend longer distances and are often exposed to the environment. It uses the more common UTP or Unshielded Twisted Pair that have categories 1 to 6, with cat5e being the most predominantly used. RJ45 is used mainly in local area networks where the distances between each network element is relatively short. Other wires are also used for extra shielding while the remaining wires are reserved in case some uses would arise in the future. One configuration uses the pins 1,2,4, and 5 while another uses 1,2,7, and 8. With RJ48, there are a few configurations that can be used depending on the situation and how they are to be used. The RJ45 that we are already very familiar with uses the pins 1,2,3, and 6 for receiving and transmitting data. Both RJ48 and RJ45 use the 8P8C modular plug and 2 pairs of the wires, one pair for transmitting and one pair for receiving data.
