Anytone AT-5555n Service Manual.

Anyone have alignment info?

I have not seen a service manual for the at-5555 so far. I did some searching on a sight in the UK I think it is. no luck there either.

Uniden must have it locked in their safe of secrets.

I was just back on the site I mentioned and one of the guys took a picture of the board for the at-5555 radios and all the Vr's were marked as to what they controlled. what pic he posted showed the asq vr and ssbpower VR. have you looked inside yours as of yet?

 

[Mudfoot]

Not yet, trying to help find alignment info. Mine needs an alignment bad.

I read that the crt ss 6900 or 6900N are the same radio. maybe you can find some info on them. here is a link for the crt radios from France.

Hope this helps.

Does anyone know how to disable Modulation limiter on the Anytone AT-5555N?

Has anyone already added a DSP Noise Cancellation PCB in the AT555N such as the NEDSP1901-PCB from BHI ?

Looking into this radio for a station addition. Would any of you owners give some input about this rig. I'm asking about the "n" version not the original 5555.

I found this pic on Amazon on the adjustment points.

Well after bouncing the decision between the 5555n and a couple of other choices, I now have one of these on the way. For it's capabilities the price is nice and think it will pair well with the kl-503hd.

Done with buying radios, enough in the arsenal to get through apocalypse.

Will be reporting later down the road, but still have to finish the galaxy I've not had time to get back to.

I have a question. What is the opt2 for? Has anyone jumped it to see what it does?

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.
