I have one of each to test and will be spending some time with each to see what I think of them. Despite sharing the same main board they are completely different animals in the flesh. 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. I think version 6 was the last one and it seemed to be pretty good. 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 will be adding to this post over the next few days as I become more familiar with the radios.
The microphone is the same shape that has always been on the AT-5555 radios since version one. Small and light. There is a bit of room to add some weights but I am sure there are a lot of folks who will want something bigger and heavier.
Memories. Always great to have. They both have 6 memories but with the N II you can program the mode along with the frequency. The AT-5555 Plus can only store the frequency as the mode selector needs to be changed physically. The AT-5555 Plus needs to be relegated to the scrap heap. It works, but is fiddly and despite the colourful display is cumbersome to use compared to the N II. It has nice audio and receives well but after you use the N II there is no going back to the Plus.
Attach the cable to the radio and turn on the radio. There is nothing on the radio to show anything has been connected. Open the program and it will show up in the 10m mode with a list of freuencies. To test everything attempt to download the list of 10m frequencies from the radio to the computer. If it reads correctly the screen will show PC and the list of frequencies will be shown in the program on the computer. This should be the same as the frequencies already in the program but it is a good idea to save it as something else anyway. Before using the software to program for the 11m and 12 m bands with the radio off, hold in Func and EMG buttons and turn radio on and release the buttons. Band 1 will show on display. Rotate the channel selector clockwize to Band 2. Hold the func button for several seconds untill Rend is shown on the display. turn radio off and on and it will fire up in the 11m mode. Change the program from the 28mhz setting to the 25mhz setting. For every band there will only be one frequency loaded which is not of much use. Using the template you can now go ahead and fill in the program with what ever frequencies you wish between 24.715 and 30.105 Mhz. Before you do this I reccomend you read from the radio and save the DAT file so if you ever mess things up you can reinstall the original 11m file.
Re the size again..what we were working on a few years back was a smaller board similar to this one but mounting it forwards and having a separate PA board at the back of the radio with forced air cooling on internal heatsinks. We were looking at 100w + When you start upping the power you need the space to cool it properly.
At my location on my ham radios and other CB types i have 0 noise but ont the 7900v i have s5 and while it doesnt affect the performance its extremely anoying. i dont think there is any easy way to turn it down
The heatsink on the NII is enormous and the chassis also has a large heatsink on the Power Regulator inside the radio. You can use FM to your hearts content with no worry of overheating that model radio.
Hello, unfortunately my at 5555nii, arrived from the venue without a sign of reception and does not transmit. All electronic components are ok, it appears to be a factory firmwere problem. Unfortunately the manufacturer does not support or offers the recovery firmwere.
Anytone AT-5555PLUS/N has the new the RX noise reduction option, NRC (extra PCB inside the radio) With a completely new designed PCB board the Anytone AT-5555 PLUS is one of the most modern and up-to-date 10M radios on the market.
High quality Dynamic microphone with UP/DN frequency and AQ controls. DC Voltage display function. SWR protection and power supplied voltage protection. Software allows to program frequency range limits, frequency channels, Mic Gain limits, factory reset function, CW side tone frequency and volume, RB holding time and much more.

My AT5555 has been dormant for quite a few years and I had the urge to try it out and test it, after giving the Cobra 29LTD AM rig a whirl. SSB receive quality was terrible, really really bad. Then I noticed that it was receiving on adjacent channels! This usually means transmitting on adjacent channels too :O
So I had a poke around with the scope and spectrum analyser to see what was wrong. I figured that something somewhere must have gone distorted and checked out the BFO circuit... urgh! It was like this:
Analyser showing 5-15Mhz. I had been using this for a QSO! I dread to think where it was transmitting! When I bought the radio, I found that the BFO was slightly unstable, after the radio warmed up it would make a little step change in frequency. It was minor, but enough to be annoying. I changed a resistor R68 from a 56k to a 68k, which you can see standing up in the photo and which cured the problem at that time. But in the long time that it had been switched off, something has changed slightly and the BFO circuit is not functioning properly again.
So, I removed the 68k and replaced it with a 47k. This seemed to solve the wonky oscillator problem (but now occasionally on power up the oscillator fails to start!) But the fine tune was all wonky too, and generally the rig was misaligned, especially on CW, receiving 1Khz off and several hundred Hz off for USB and LSB. Tuning up and down with the clarifier was not continuous, it stepped incorrectly every 100Hz and was just plain wrong.
First reset the AT-5555 by holding down FUNC and SCAN while turning the radio on. On my radio, this defaults to the frequency range 25.615 to 28.305Mhz.
There is a service menu - Turn on holding FUNC, then press RB, then NB, then DW. There is no documentation for these settings so I have worked out what each of them are.
For each MODE switch position, there are alignment settings. Some are shared. You can scroll through them by pressing FUNC. The settings are bfC, fr0, fr4, fr5, fr9, loC.
bf adjusts the frequency of the 10.24Mhz BFO
fd0,4,5,9. What do these control? Hmmm. Bingo! These are for fine tuning! The radio performs fine tuning by adjusting the voltage across a set of varicaps, which affects capacitance and hence the frequency of the oscillator. These must be the limit voltages for .00, .04, .05, .09
lo controls the local oscillator offset.
I found at the end of this I was still slightly off on USB and LSB. If this is the case change lo *first* to get as close as possible, then tweak bf for the final step. This reduces the amount bf needs to change, preserving your fr settings.
Go back to normal mode and check each mode for correct operation. Check the fine tuning is even and smooth. If not, repeat the fr0-9 steps for that mode. You can try one click for bf if the radio is very slightly off frequency on CW, USB or LSB. Any significant change of bf requires fr0-9 alignment.
Feedback and double checking welcome on this procedure.
I have a Anytone 5555N2 and the Digirig cable for the AT-778UV and the setup has worked great from the first time trying it. I have used the Digirig rev 1.9 and 1.10 on it. Everything works fine without modifications.
