Question about Sirius Sportster 4 SP4-TK1 Satellite Radio Receiver with Car Kit

4 Answers

Sportster randomly turns off.

I have my sportster on a boombox base, the base is receiving power and the sportster will come on whenever I hit the power button. But suddenly it has begun to shut down randomly. Once it said "Battery Low" but I assume it's supposed to be drawing power from the base?

This is my second sportster in a year and a half. These things don't seem to be made to last.

    I have the same problem "Low battery / powering down" on the boom box with a sportster 5. I bought 2 complete boom box and radio both have the same problem. I checked the power cord 122 ac volts going into the charger and 12 dc volts at the boom box end. I don't have a amp meter. Works fine in the car kit. Has nothing to do with heat.

I had the same problem When I looked at the settings for display the brightness was set to the highest level in manual mode. I set the unit to automatic the screen dimmed and I have not had any issues since.

Your answer is border line retarded at best. The problem is your sportster overheating not your boom box. Someone said you can dim the lcd on the sportster and that could help. No wonder these PAS radios carry a 30 day warranty. I have the same thing happening. Mine happen like clock work. I put it on and it completely shuts down after 10 minutes. Does not do it with any of the other 3 sportsters on my account.

I too started experiencing drop-out/unit lock-ups after two months.  After resetting to factory defaults,per Sirius phone support, without results, only pulling out power adapter would reset the unit.  I suspected a design problem with heat.  I wrapped the unit with a medical cold pack and got stable operation.  Given all the complaints I see on this web site, I suspect Sirius is well aware of the issue, and not addressing it appropriately.

Remove the batteries from the boombox. If there is no batteries in the boombox, and it still does this, then the boombox itself is no longer any good.

Sportster 5 turns on and off randomly every few seconds hooked to a dock.

Sportster units get very hot ! If you use it in the boombox stop ! Take the radio unit out - remove the silver cover from the boombox ( don't overlook the 2 hidden screws under the speaker grills ) take a dremel tool with a cutting wheel - and cut all the shrouding away around the top of the reciever. This will allow the radio to run way cooler ! I also drilled several holes thru the swivel mount to allow better air-flow !

Why does front cyl. base gasket keep blowing out on 1984 sportster with stroker kit?

It's unusual for an Ironhead Sportster to blow a base gasket. The reason is that the cylinder bolts directly to the crankcase via four short studs. I would suspect either a warped cylinder base or case. Now, the Evolution Sporty's are bad about base leaks.

Good Luck

My sirius radio sportster works sometimes and others doesn't

Buy radio shack electronic contact cleaner (in a can) and spray a small amount on the male connector from the antenna wire, and spray a small amount on the male connector in the base of the Sportster that the sportster interfaces with. Place the antenna connector onto the base unit and remove it several times and swirl it while connected. Place the sportster into and remove it from the base several times. This usually will fix the issue. Sat signals are extremely sensitive to the slightest oxidation or dirt or whaterver on that tiny antenna connection point.

When i place my sirius radio into the base, driver side speaker goes off and on but most time i only hear the passanger side speaker working, I had my sirius sportster for 3 years. I think it is the base,...

when you listen to a cd or the normal radio does the drivers side speaker work? if it does then it is most likely the base is the problem. you might have a loose connection in your car. or the speaker is blow.

Your best best is to replace the units. Sirius usually does it for free for existing customers. You can a good discount on a new boombox as well. The new models are designed to work with more Sirus receivers on the market.
