Jay-

I think the misunderstanding is that his radio is an A3 Handheld Control Head (HHCH) model (as least, I'm guessing). The A3s have a different MLM (slightly scaled down) from the A/B/C 4/5/7/9 family, so there's no easy way to make this radio into a dashmount. Unfortunately, I can't comment on the programming, as I've never even seen an HHCH radio, let alone programmed one...

Please excuse the "generic" answers. I don't have Spectra RSS here and can't

exact key strokes.
The buttons on the dash mount or remote control head are programmable.
You can also purchase the correct buttons from Motorola Parts, (such
as EMER, SCAN, etc) and put those in blank or already used buttons.  
Yes, you can program a control head button for
talk-around or "DIR".
As far as the programming, most Spectras are 128-channels (max).
In the software, you must first "add" the channel slot and
then program the information (PL, TX, RX, power out, MDC) into that slot.

I recently got a High power VHF Spectra.  This radio has the interface box, 
the secure module and the control head on thhe microphone.  The radio is 64 
channels.  When viewed with the RSS, it implies that the radio is 128 
channel capable.  However I cannot find a place to change the number of 
channels fron 64 to 128.  Is there a trick to do this or am I missing 
something?  The microphone does not have a switch for talkaround (maybe I 
do not need it). There is a switch for secure.  Can this switch be 
reprogrammed for talkaround?  Can the secure box and the interface box be 
eliminated?  Al that I think that I need is the radio and the 
microphone/control head.  Can another control head be used with this radio, 
or is the radio unique enough that only the microphone/control head will
work?

A lot of questions.  This is my first commercial synthesized rig.  I do not 
want to destroy the codeplug in the radio. I see that the data is stored in 
EEPROM and that the processor is a 68HC11.  Is it possible to remove the 
EEPROM and reprogram it in an external programmer to change the 
personallity of the radio?

Thanks
