Just found out that you can’t have the Noise compander and the Noise reduction on together.

Of course you will need the manual to see what the menu number is associated with. Thats handy because sometimes it is tricky to know exactly where you are in the menu. Another thing I noticed on this radio and not on the earlier versions of the AT-5555 that when you are in the menu the channel indicator shows the menu number. Not much, but certainly doesn’t reduce it on Sideband. NC? So far it just seems to make more noise. The AT-5555 Plus has 8 switches with 15 functions…surely 2 of those could be repurposed? Better still: put the echo controls into memory and put the NR and NC on the echo knobs so it could be readily adjustable. Adjust it in the menu and activate it on a switch. You need it on a button and you need it adjustable. The other thing with the noise reduction is that you have to go into the menu to activate and deactivate it. It also takes a few miliseconds to start working which is a bit frustrating. Need to play with it some more, but it ressembles setting 5 on the N II and tends to distort the received audio. Some background artifacts almost like FM broadcast bleed thru, but we don’t have any FM transmitters nearby. My initial impression of the noise reduction on the AT-5555 Plus /N is that it is too aggresive. NOISE REDUCTION The menu on the AT-5555N II only has one noise cancelling feature. Other than that there is not a lot to play with in the menu. The most important is the mic gain! It comes in as item 01…Out of the box it was set at 31 out of 63 and I cranked mine up to 60 just because that is where I used to have it set on the other anytones. There are 25 settings in the radio’s software settings. They are the compander under item 06 nC and the Noise Reduction nR under Item 08 in the menu settings. It actually has 2 receive noise reduction settings, neither of which are adjustable: ON or Off from the menu which is accessed by holding down the func button for 2 seconds. Plus N means it has the noise reduction features installed. So for now I will just go through the new AT5555 Plus /N. I will be adding to this post over the next few days as I become more familiar with the radios. You can order the AT-5555 Plus radios with or without the noise reduction but I think the N II has it built in. I think version 6 was the last one and it seemed to be pretty good.

The AT-5555 Plus/N is very similar (almost identical really) to the older versions of the AT-5555 which we first looked at many years ago and was continually refined and improved over the following years. Despite sharing the same main board they are completely different animals in the flesh. I have one of each to test and will be spending some time with each to see what I think of them.
