Memory channel management is a different kind of thing. It is a time-consuming task to select the channels and add assign them to a memory group, unless you use the ADMS software.
Another point to note is that if you rotate through your memory channels and you reach the last channel you have to turn the DIAL in the opposite direction yourself. So there is no jump from the last memory channel directly to the first memory when you turn the DIAL key to the right.
In my opinion, the set could have won a lot of points as a mobile set because it is standard equipped with Bluetooth. However, when I compare its implementation to an FTM-100 with BU-1 and BH-1 headset, I am somehow disappointed. When I use a parrot function to verify my audio it doesn’t sound very good. And then it doesn’t matter whether you use a standard headset or a more expensive one with noise cancellation. By the way, the headset must have a default PIN code of 0000; this is not a choice, so Yaesu again says farewell to the older headsets such as the BH-1 and BH-2, where the pin code is set to 6111 by default. The audio via bluetooth sounds a bit pinched, not clear and far from nice. In a silent shack it is still do-able, but the question is how your counter parts, especially if they are mobile, will respond to your modulation. A plus is that the standard PTT toggle works, so you have to press the PTT button once to start transmitting and once to stop transmitting.
In short, the FTM-300DE is a nice set, but there are plenty of areas for improvement that can easily be addressed with a firmware update.
