There are three methods of charging the HNN9044 battery used in an SP10 radio:
1) Use the HTN8232 10-hour wall charger. It plugs into a jack under the flap on the side of the radio (opposite side from the PTT button).
2) Use the drop-in style charger by setting the radio in the charger (this works if your radio has silver battery contact showing on the bottom.)
3) Use the drop-in charger to charge the battery alone. (The battery will set in the charge crossways to the way a radio would set.)

Lastly, if your battery will not charge by one of the above methods it might need replaced.

Best regards.

Trying to program sp21 to a sp10

If your SP21 and SP10 are both either VHF or UHF, it is possible to program them to match one another.

The SP10 is limited to 16 available channels, programmable by 4 dip switches behind the battery compartment of the radio. Great care must be used in removing the entire battery tray to get to the dip switches. Many times we see radios which have damaged mylar battery leads when someone attempts to get to the dip switches by removing the thin plastic/copper liner behind the battery. DO NOT remove this piece. It will come out with the battery tray. The tray is somewhat of a picture frame which holds the battery in place. In the SP10 radio it is removeable by slipping a small screwdriver or thin car key in the slot at the bottom of the radio and gently prying up. This will begin to dislodge the tray and you can pick it up and pull it out of the radio. (The upper battery contacts near the center of the radio will remain with the radio. The bottom battery contacts, if any, will come out with the tray.) At this point you should be able to see the 4 dip switches. The four most common VHF settings are:


Your preference on these should be limited to green and blue dot, as they are license-free, and are the only wideband frequencies still okay to use after Jan. 1, 2013, when the narrowband change takes place.

If your SP10 is UHF, or has 8 additional dip switches in the lower left below the main component board, you have PL. It would be best if you call someone who can help you with programming, as it is too lengthy to type more about this here.

The SP21 is PTT programmable. You hold in the PTT button while turning the radio on, and it will announce its frequency, press the monitor button once, and it will both lock in your frequency setting and announce the PL code setting. Either of these is changeable by pressing the PTT, followed by pressing the monitor button to lock in the new setting.

The primary VHF settings for the SP21 are as follows:
Freq 1 = Red dot
Freq 2 = Purple dot
Freq 3 = Blue dot
Freq 5 = Green dot

Once again, your preference, if you are VHF, should be toward Blue and Green dot frequencies.

Best regards.

Looking for a 21" antenna for a Motorola SP10

There are custom made antennas for portables. But the better solution is by eradiostore, use a mag mount.1) custom portable antenna, expensive.2) Motorola adaptor to BNC to longer antenna (portable, car type or base station).
3) NO power increase, not only are those frequencies designed for low power the board inside the radio cannot handle the heat and is not changeable or adjustable.

Rotel processor bypass for Audio Research SP10

If I understand you, the 'sound' of the AR preamp is what you're trying to preserve. Presumably you're just running a phono through it as nothing else needs a preamp these days.

The multichannel inputs bypass all of the Rotel's processing except the volume. Use the Front L and R.

Delete it from your Razr, turn off the bluetooth and recharge it to full. Try pairing it again. Make sure you enter the passkey correctly. Check the manual for the bluetooth if you dont know what it is. It is usually 0000.
