dual-head radio question

[Riktar]

If I am running a KRK-6DH with a TK-890 head unit (Single radio controlled by 2 separate control heads) is the volume able to be set independently from either control head? Or does changing the volume level on control head "a" also change the volume level on control head "b"?

Reason for asking is for the consideration of having one radio service the upstairs and downstairs of my home.

So I do that very same thing with my Motorola CDM1250. They have a jack in the back that allows for a second mic and speaker. I use the low output side for the second speaker along with a set of amplified computer speaker so that I have separate volume controls. I have three base units. One at the front of the house with the unit in the leaving room with a second mic and speaker on the front porch. The second base unit is in the back of the house with the unit in the office with a second mic and speaker in our up stairs bedroom. The third unit is in the unattached garage with a second mic and speaker outside in the back yard, so no matter were you are at you can hear it and transmit back. 

 

This is the kit I use.

I believe if the speaker is hooked to the head and not the deck it will allow individual volume control. Its been some time since I had a 90 series in a vehicle but our ambulances had them and we could control back to no volume while front is talking.

Thanks for confirming the volume question!

I never considered that possibility. I will check the back the manual for my TK-8180 and see if the back ports have that same capability!

In the Astro 25 series mobiles, such as the XTL5000 remote mounts, each control head has their own speaker connection thus, each control head individually controls their respective speaker.

One draw back is that you can't change channels from the remote area, it's not really a problem for me because I use it for family communication and not really bouncing around simplex or local repeaters channels.

That should not be a problem since I have a specific set of mixed (repeater and simplex) channels that I seldom change. The ability to set volume control for either speaker is paramount to this project.

Noted for future reference. Thanks!

I know what you mean, I originally used the high side input for a external speaker and quickly found out that was not going to work and switched it the other way.
