Hoxin and custom cable

Hi Guys

I have picked up a Hoxin AV908 desktop mic but i am struggling to get a lead for it
its got like a ethernet plug into the base mic and i need it to go to my 6 pin ss9900
i have tried knights they stopped doing custom leads
Does anyone know where i can get a custom mic lead from for a Hoxin AV908 to a SS9900

Thanks

Hi Andrew,


A quick scout around the old internet didn't show up an adapter lead for your setup.

If it helps any the wiring details for the AV908 is on the following link :-

The wiring for the SS9900 can be found here :-

That'd be enough info for someone to build their own adapter lead or indeed for someone to build one for you.

Sorry I couldn't be much more help and I hope you get sorted. (Nice mic BTW )



All the best,
Victor

6 pin plug and cut the end of the cable you have and fit the 6 pin plug.
Victor has given you the wiring for the mic.

I know you siad Knights have stopped making leads they haven't totally stopped it's only while the Bat Virus is stopping people doing there jobs and his workshop is closed as sayes on the website, but my mate actually phoned them to ask and he said he would make one for him for a radio/mic he needed, so if you haven't might be worth phoning , there use to be someone on ebay who sold them I'm sorry cant remember the name though try typing in cross over mic leads on ebay see what happens.

thanks guys for the replies and help looking at it i think i might have to have a bash on my own
its just working out what goes to what
sorry for sounding dumb the modulation pin on the ss9900 is the mic input wire on the mic
the up down wire is single but there are 2 connections on the mic
ptt is the same ptt
we have the shield thats the braid wrapped around the white wire ime guessing thats the earth so would go to the gnd on the mic
just confused over the shield

Hi again Andrew,

You'd have to hunt around the web for details but luckily I won't send you up the 'Google it!' path

It's always best never to assume wiring colours but trace them with a multimeter. However CRT did stick with a standard colour scheme. The colours and function are as follows :-

Shield - Ground
White - Audio (as you say 'modulation' or mic audio)
Red - PTT (Push To Talk)
Blue - NC (Not Connected)

It does become a little more complicated for the Up/Down functions....

A resistor of 3K9 value goes from the PTT connection (Red) to the 'Up' button. (It connects this to ground when the 'Up' button is pushed.)

Another resistor this time of 2K2 value goes from the PTT connection (Red) to the 'Down' button. (Similar to above but the 'Down' button connects this to ground.)

...and Bob's your Uncle


You'll see how these connections work if you look inside your original CRT microphone.

You might need to fiddle about connecting these extra resistors to your wiring or you could even forget about them and just use the audio, PTT and shield ground. (Some mic adapters don't even bother with the up/down functionality!)


Well done for having a go yourself, (always admire someone's DIY efforts), and let us know how you get on.


My payment for this exemplary help? 

Just a simple word of 'thanks' goes a huge way.

If you feel really grateful, you could even click the 'like' button at the bottom of this posting and even go as far as clicking the '+' on the top right giving me a vote of thanks. I'll be chuffed to bits and you'll never be indebted to me ever again.


Honestly, I wish you well.

All the best,
Victor

Thanks for that much appreciated liked and voted

Aha, you're a diamond Andrew

Thanks very much. (A 'thanks' right back at you too.)


It can often be a thankless task as an admin sometimes, we often bend over backwards to help members where we can, (not forgetting other CT members helping too), and that little 'thank you' goes a very long way. It's more than enough reward for the voluntary time we put in to assist fellow members with a passion for radio.

Do let us know how you get on with your mic.


All my very best to you,
Victor
