Okay I'll actually contribute.
There is a micro switch on the edge of the bench.
There is a micro switch inside the desk that can be activated with the knee, much like a sewing machine switch
There is a foot switch
There is a button on the screen via keyboard or touch on the laptops.
I have, had used a wireless PTT. That I haven't used it in years might tell you what I think of that.
In any case I rarely use more than one. All can be disabled with a switch.
Short addendum.
As far as VOX goes I can't seem to use it. I must be broken. For PTT microphones I use a press down bar and never got used to a chicken choker. The lock function has been disabled on all my desk microphones.
Otherwise useless information.
I use cardioid pattern microphones exclusively with one exception. I have an overhead microphone in the shop that is used for computer, intercom, telecoms, and transceivers. It would have ended up in the trash because it hears
absolutely everything.This is the one place where it has a use.
The reason for the cardioid pattern is the usual household noise as I have never had an exclusive shack space. I try to limit noise from other than directly in front of the microphone.
There is one accidental effect from all these operating positions. They all sound alike. Other than the garage microphone being a bit down from the others the frequency response is near identical for all .
Anecdotal.
Three of the members here have heard the TS-830S and spoken to me on the phone. That they find very little if any difference between the two I'll give to the Kenwood's audio processing.
Important note.
In all cases the the PTT is the tip of the iceberg when considering T/R switching. There are many good articles on sequencing. Read how ever many of them you need to understand. I only mention this because there are a very few ways a remote PTT can interfere with sequencing. Learn to recognize and deal with out of sequence PTT events. Now this is going to hurt and create a bit of a firestorm. By it's use alone, a carrier operated relay as is found in virtually all 11m amplifiers "hot switches" . This is bad news on so many levels. As power levels go up it gets worse. In many cases physical adjustment of the moving contacts will stagger events enough. Delay circuits will be needed otherwise. The simple fix is to not use a carrier operated relay.
Then...
