One tick box wrong can silence everything. It is a bit fiddly though, and can take a while to setup. While your PC isn’t as portable as your scanner, it is a lot cheaper alternative and give you an idea on what you can here. However, you can do it all at minimal cost on your PC. It is clear my old scanner won’t cope with this at all. So instead of needing to pay for 2 frequencies for two channels, you can have two talk groups on the one frequency.Īnd this is just the start. You can also transmit text messages, your location and so on, all behind the user that is talking and on the one frequency. Effectively you can have two different conversations on the same frequency, and although every second micro second is lost, to the user you wouldn’t know. What this is the radio will do one micro second for T1, then switch to T2 for the next micro second. For example, DMR can have T1, T2 or higher, where T stands for Tier. Then within these digital modes are different ways of using them. Some of these are popular, and some are not.

There are several reasons for this, but put simply, digital seems to have a longer range, is clearer and you can do a lot more using just the one frequency.įor the hobbyist, to make matters hard, there are many digital modes.

While there is still a lot of Analogue transmissions today, even a lot still on AM especially when it comes to Aviation, however most have gone to digital. If you don’t have one of the latest and greatest expensive scanners, you will struggle to listen to a lot of transmissions.
