Does 4 watts make a difference over 1 watt on UHF? Let's find out

In this video I find out if 4 watts really makes a difference over 1 watt (or 3.1 watts over 750mW to be precise). I use two Motorola GP340s for this test, the 'Ex' version which is designed to be used in places where there may be flammable or explosive substances present and a standard one, I do a power check on them before leaving the house then test them at two points. There is this myth about power amongst those that don't have an Amateur radio licence that more power equals greater distance, particularly amongst those that use CB radios with linear amplifiers or Chinese radios and widebanded 70cm sets on PMR446 (as PMR446 frequencies fall into the US 70cm allocation), the truth of the matter is that it all comes down to many factors, location (I was in a built-up area with many metal buildings between me and home), antenna placement at both ends (my receiving antenna was indoors), feedline at both ends (RG58 in my case at the receiving end which is not ideal for UHF) and how well matched your antenna is at the transmitter at least. Keep watching to see the results, as my SDR has an S-meter you can see that value in the clips of the received end. #hamradio #433MHz #UHF #Motorola #pmr446 Help support the channel, basic level for only £0.99 or early access for an extra £2.00:    / @paulmcgeem0wnu
