UHF vs VHF – What is the difference?

Here at Radiotronics we tend to be asked this question a lot, and for good reason. Picking wrong could result in your radios not working as effectively in your business, or not even working at all. Firstly, this is what they are:

UHF – Ultra High Frequency

This is the frequency band of 440-470mHz for business-grade two way radios. This frequency band is often selected if the radios are to be used both indoors and outdoors. A UHF wavelength is smaller (about 70cm) than VHF which means it is much better at penetrating walls and obstacles. Because of this, UHF is a much more common choice than it’s VHF counterpart, for example in schools, offices, warehouses, etc. Wherever there are walls, think UHF!

VHF – Very High Frequency

This is the frequency band of 136-174mHz for two way radios. This band is often used for the outdoors only. VHF’s wavelength is much larger (around 2m) than UHF, which means it can really struggle through solid objects. However, in the outdoors, it tends to have better range than UHF in open environments, such as farming, hiking and outdoor activities.

One very important thing to know about these frequency bands are that they do not mix; UHF radios will not work with VHF radios and vice versa. These radios are manufactured so you could not add a frequency if it is not within the range.

If you have purchased licenced radios from another company in the past and are wanting to purchase more from Radiotronics, we can confirm what frequency your radios are already on before you select a band and make a purchase. You can either contact us and quote the long model number on the radio (which can be found when you remove the battery on a sticker on the radio side) or alternatively take a look at our detailed product pages which are being updated with this information.

If you have purchased radios from Radiotronics in the past, your previous invoices will confirm your frequency version.

If you are wanting to purchase a brand new fleet of radios and can’t decide which frequency band would be best for you, please give us a call and we will be more than happy to assist!

Motorola CPS 2.0 Is So Slow!!!

Motorola CPS 2.0 Logo

Yes! You’ve noticed it too then? A problem with the latest version of CPS 2.0 for Motorola MOTOTRBO radios is that it appears to be so slow!

But there is a fix. It’s a bit of a mess around, but it seems to work.

Our colleague, Sam from BTW in Canberra, went under the hood so-to-speak and made some adjustments in CPS 2.0 configuration file which makes most, if not all, operations many times faster than before.

Until the necessary improvements are made in the next release, here is the modified configuration file:

  • English [MD5 hash e0b529485e2efdd726fb1c37705f6b04]
  • All other languages [MD5 hash b126e04c65e8b706ce15851317e88a5d] results might not be as fast as the above file.

To use it:

  1. Download either of the above files. (Optionally confirm the MD5).
  2. Make sure CPS2 is closed.
  3. Copy(overwrite) the above downloaded CPSshell.exe.config file to C:\Program Files (x86)\Motorola\MOTOTRBO CPS 2.0. Optionally, you can create a backup of the existing file by renaming it to CPSshell.exe.config.bak.

NOTE: Hidden Cotcha – Must Be On Latest V1.0 Firmware

Your MOTOTRBO radio MUST be on the latest verison of 1.0 firmware to be able to upgrade to 2.0 firmware. That means that you cannot upgrade a DP4400 on really old firmware to 2.0 firmware without first updating it to the 1.0 latest firmware.

But don’t worry, we’ve got your back. If we have supplied CPS 1.0 subversion 16.x within the last 12 months, we will supply CPS 2.0 for free*.

*We must have supplied CPS 1.0 subversion 16.x within the last 12 months.

The Current CPS 1.0 Subversion 16.x Version

Bearing in mind you will need CPS 1.0 subversion R16.8 to upgrade your old radios to the latest version of v1 firmware, you will also need CPS 1.0 subversion R16.8 and the firmware that corresponds to your radio.
