Re: DTMF with Mic
What's all of the fuss about?toggle quoted messageShow quoted text
If you use a second same type mike remember the IC-7000 mike generates control data, two will loads down the data line.....
Simple LOW COST Solution…..
I found my OLD DTMF pad that I used in early control projects it is mounted in a nice desktop case and found a nice shielded cable (CAT6) attached a RJ-45 on one side spade terminals on the other side, found the power, PTT and audio pins and all is well in TT land now I have the pad activate the PTT when you press the button its cap coupled audio and everything works just fine total investment $1.75 no problems with repeaters or IRLP control.
All of this from a 27 year old Bell Labs 16 button TT pad, and it even has lights when you press the buttons, what a country....
For mobile I found a TT pad that I used on a old HT-220, yes crew a HT-220 that fit nicely attached to a small plastic project box, sane type of attachment as the home station the only difference is that I needed a different coupling cap and the pad is not lighted, this one was bit more since I needed a clip to attach the project box and the cost of a white LED to see it at night.
Let's use some of that ham ingenuity
