I am trying to find someone that can do or can share the how to information for this modification to the "Albrecht AE 6110 / Anytone Smart 10" to add a Rotary Switch with push button abilities that enables channel selection, direct access to the Squelch menu / ASQ menu for easy Channel switching with function key for direct access to squelch and the autosquelch (ASQ) menu. I exchanged an email correspondence with a savvy German radio experimenter that did about 10 of these added channel selector knobs, etc.. mod conversions, however he is no longer doing them; so I emailed him back recently and asked if he could share a how document if he has one and waiting to hear back from him. I also read on this forum that someone in the UK has figured out how to do these modifications on a work for hire basis as well, but I still haven't been able to run down whom that is or otherwise. I am including some pictures that I screen captured out of a youtube video that shows these modifications for your viewing as well. Understand that as a part of this modification the microphone cable is re-purposed and directed out the back of the radio and a standard connector added so that you can have other microphone options available to you as well and optionally still retain microphone based channel selection, etc.. .
My intention is to use this external microphone connector to connect it to a bluetooth device (bt-trx.com) that allows the radio to be connected to a modern car audio hands free communications system such as is common place with mobile cellular communications today for added safety while driving. Note that the br-trx device adapter also affords both wired or wireless both push to talk capabilities as well.
Any input or feed back relative to moving these endeavors along would be much appreciated. Thanks for your viewing and input of this post.
I thought I would include some pictures of the BT-TRX devices along with an translation to English of the German BT-TRX open source bluetooth project as well since I am sure likely this will be of interest to many people on this forum as well:
I've looked into doing this before but decided it just wasn't worth investing the time into since it requires a programmed microcontroller if I recall correctly to handle the rotary encoder and it's such a tight squeeze to fit it all inside without removing the speaker for space.
Only other thing I could figure is using a flip flop and NAND gate chip to get the up/down from the rotary encoder. Then run the up/down logic high/low into a bilateral switch IC like a 4066 to control the actual channel up/down of the radio so to isolate the circuit with the radios. Problem is fitting the logic circuit on something tiny enough and would require SMD parts.
I just cut my mic cord about 4" from the radio and soldered on a 4 pin mic jack so I can plug in any external mic I want and left everything else as is. So much easier to mod the larger radios lol.
