OK I GOT INTO P25 , HAD NO IDEA ABOUT WHICH RADIO TO BUY. WITH THE HELP OF FELLOW HAM

N2HUC PHIL

I GOT THE RIGHT RADIO , NEXT FOUND OUT ABOUT THIS TING CALL A AVA or SVA\WHAT IT DOES IN MAKES YOU HT MOTOROLA ASTRO SABER RADIO A BASE RIG OR A MOBIL RIG.

HERE IS WHAT I FOUND YOU NEED.

 

Notice in the above picture the key if you don't get the key's here is the answer:

The MOT-1 key has the exact same cuts as found on a 2135 key, but it's made on a

different blank (Ilco 1041-N).   Have the locksmith copy your 2135 onto

the Ilco 1041-N blank but use the photo to get it right side up.  
 

 

I'M on 146.565 simplex. And from DV4  Mini

on FSC002 room 10 the Florida Room, come join us.

 

There is a decal on top of the Astro SVA that gives the following useful data:

"CAUTION: Inserting the wrong radio may Damage the Adapter. This Adapter works with ASTRO Digital SABER, SABER and Systems SABER radios manufactured on or after September 1, 1994. These radios can be identified by their serial numbers: The 5th character (year) must be "U" or later (V, W, X, Y, or Z). If 5th character is U, the 6th character (month) must be "S" or later (T, U, V, W, X, Y, or Z). Use Adapter ONLY with approved radio models. For radios manufactured prior to this date please contact: Motorola at 1-800-523-4007 (ext. 112) for upgrade details." The phone number is long gone remember these unit are 30 plus years old.



One thing to note when using your SVA, if you pull the radio out while it is on, you may loose your volume control (any other controls). This may be intentional, or it may be a firmware issue. Since the AVA doesn't know when you are going to remove the radio from the cradle, it can't completely return control of the radio to the user before it is detached. As a result, some radios still pretend that they are in the AVA, and don't respond to user controls without a power cycle. On the other hand, there are some radios that seem to work fine some/all the time when they are pulled out of the SVA. This points to the firmware in the radio and the newer revisions may be able to compensate for the loss of the SVA control without the radio being power cycled. Just something to be aware of."

I have a Astro SVA that has the decal. The correct SVAs are hard to find. I had a long wait to get one on eBay and it was on the spendy side. About 5 times the rate as an old, non-Astro version. Good luck and keep hunting.

 

Facing the 4 pin Male Plug on the rear of the SVA here are the Pins left to right as follows:

Black = Vehicle Ground (or "-" Power Connection)
Green = Headlight Sense (dims the backlighting when
+12Vdc is applied...can be left disconnected and the backlights
will always be full brightness.)

Yellow = Ignition Sense (Turns on SVA and allows
charging to begin when +12.0 Vdc is applied.)

Red = Vehicle Power (+12.0 Vdc Power Connection)

 

Next you are going to need is a Amplified Speaker Motorola NSN6054A

  Make sure you get the wire harness with the speaker
