One of the big differences is the types of frequencies available in the intercom, all of which have their own unique pros and cons. Two of the most common and popular in use are the UHF (Ultra high frequency) and MURS (Multi-use radio service) frequency intercoms.
UHF intercoms have to their advantage distance, along with being able to be used with many pre-existing UHF radios. This coupled with the fact that UHF also has better building and barrier penetration, is why many have chosen this option when it comes to truck scale intercoms. Although, it?s not all good points - a UHF intercom requires the user to have a FCC license to operate it, or an IC if you are living or working in Canada.
Then there is the MURS, again with good and bad points. One of the top pros is the fact that as yet MURS frequencies are not crippled with overuse, and no license is required for its operation. On the flip side, it also doesn't carry the range of UHF, is limited by up to 2watts, and it has a significant reduction in building and barrier penetration. You will also find that the use of MURS intercoms are as yet not legal for use in Canada, which many find is a big down side.
So when deciding on your choice of a truck scale intercom, you must first evaluate what your needs are and the area in which you will be using the system. Of course, if you live or work in Canada some of your options will have been taken away from you before you have even begun. Again, in the case of UHF you will need to ensure you have your FCC license prior to purchase, and that your paperwork is in order.
Not such a cut and shut case as many would think. The best way to truly decide what is best for you would be to ask questions from truckers, find out why they feel the system they have is a the best system for them. Visits retailers, and if possible try out systems in action. The last thing you need is to purchase a truck scale intercom system and find that six months down the line it doesn't suit your needs and requirements. It could be a costly mistake.
