Anytone 6666 HiFi mods?

Gold Finger at World Wide Pirates of DX would be able to figure it out I am sure.

You need to be very careful working on piggyback/replacing components like capacitors on those boards for hifi mods

Looked at the 5555 schematic and compared to my Lincoln 2 . Also compared a blurry copy of the 6666, they are all the same. I modded my Lincoln 2 hifi front to back TX and RX. Left a copy over at GF site of my mods but I missed the portion between the front jack and the first mic preamp.

Goldfinger has done it here:

I will try the capacitor swap with the noted capacitors that Goldfinger had noted. I haven't got this 6666 yet from Amazon but I'll give it a try. I have had great success with better audio friendly style capacitors in the past radios I have recapped for a better clean clear and smooth audio purposes. It does make a difference to my ears anyway. To those who are looking to get a more wide and full higher fidelity sound from your rigs, I have had success with rack gear and a good flat studio microphone. It sounds over the top and it is...but you will love how you sound and others you talk to will be dumbfounded on how your broadcast quality on a cb radio. All my rack gear is either used or new for less than 100$. I hook it straight into the microphone plug on the radio (everyone says it doesn't work that way). I must have good luck then. My latest radio I have it hooked up to is a Bearcat 980 with the screen all dimmed like everyone else's. On air Testing on channel 23 gave me an unsolicited report that the audio was 5 khz on both sides and sounded great. And that was on a junk radio without mods. Give it a try and you may like it. Maybe someone can tell me why this occurs, but In my mind I just think that I'm overloading the inexpensive filters and it has a good sounding benefit.

If you push on the filter edges, they will give a little. Some people boost the eq at the edges which seems to help. Let us know how the 6666 does with the capacitor mod.

I'd like to hear more details on your rack gear and the flat studio mic! I've never ventured into the hi-fi territory but I like the sound of it, pun intended . Please share.

That was the same thought that I had but just wasn't sure. Thanks.

About my rack gear and the microphone.. I learned the hard way. For me, venturing into the hifi audio world has all been trial and error, but I think I have found a solution to midfi and hifi that works for mostly all radios. You have to know how to rewire a mic plug and be able to hear so you can adjust the knobs, that's basically it plus your rack gear if you go that route. Many people use a simple audio mixer and that works but you will not be able to push your radio enough to get the hifi sound, it will sound very nice and better than stock and that's fine...but I wanted more. I started out with a simple cheap studio mic for like 30$ and an small mic preamp. Worked fine. Eventually I picked up a rack mounted mic preamp. Then I added a multi band equalizer. Then I added a rack compressor to smooth out the volume level on the highs and lows and to eliminate background noise. The magic happened when I added a sonic exciter. The sonic exciter gave me the expanded range of fuller audio. I run 4 or 5 rack units when I transmit depending if I want reverb I'll add the 5th unit. It's a lot of stuff right? You don't have to do all of that. The key to my puzzle was getting a microphone that has flat audio characteristics as possible element. The flat or wide range sound of the microphone gave the ability for the rack gear to do it's magic. I have ran just the mic and preamp with the sonic exciter and have great sound. I know rack gear is old tech. I just didn't want to have to depend on a computer program to run the audio of my radio. I use xlr cables and just wire the XLR to what ever pin microphone you need for your radio. They even sell premade ones made by Heil that even have a 1/4 phone plug for your ptt switch. I have tried these rack units on a cobra 29, uniden bearcat 980 and an old Kenwood ts440. The Kenwood was able to be pushed to about 9khz on both sides of the center frequency and did have broadcast quality sound. All these radios were on AM only. My guess is that most cbs could be pushed to about 5khz this way. It has worked for every radio I hooked this set up to. I was plagued with lots of rfi in the audio cables so I had to buy lots of ferrite snap on beads to help with that. Flat range mic, mic preamp, sonic exciter. Those three worked well for me.

9khz wide by pumping audio thur the mic jack on ts 440...... er.... I don't think so.. maybe by pumping audio thur acc2 port on the back but not the front mic jack.
Or did I mis read your comments

You don't have to believe me. I put in an upgraded ceramic filter that was different from the original. I just followed what I have read online to do. that ceramic filter also was used for AM transmit on that radio. The 9 khz is not from any of my test equipment. Those reports were from 2 different people telling me what my bandwidth was on their end during DX. I have never read anyone doing audio the way I do it. I have always read it doesn't work that way. I just like to experiment and I'm sharing my results.

Oh OK, you changed a filter .... that will do it.
Cool... I believe I talked to you a few hrs ago. Nice sounding 980

Lol seriously? I was on a few hours ago. That 980 is just a temporary radio untill the 6666 comes in. People have said it is quiet but any louder it gets distortion. The screen has malfunctioned from cheap factory parts and it struggles to do legal power. Ssb at best is like 5 watts. I had it hooked up to a kl503. Are you the one that has the 6666 with asymod or the 7300 with asymod. I talked to two people with those devices.
