Stops receiving signals

I have experienced the same with numerous different, "quote un quote" atomic clocks! Please don't forget that this sender unit, that goes outside, generates a RF Singal to be received by the clock inside. This unit transmits a signal 433 MHz signal approximately every. 3 minutes, and after so many years the sender unit's RF section(electronics) just goes out or no longer function properly or not at all! The transmitter/sender for this model number, according to "3M" is obsolete and can no longer be furnished, DRATTS !!!!!

Hi Kathy,

It sounds like its the antenna, although it could be the docking station itself, or even the receiver. The best way to narrow it down is by testing against other equipment (if you happen to have other docking stations and or antennas) If it produces the same result you know its the radio. If you swap antennas and it works, obviously the antenna; and the same goes for the docking station. You can find replacements at tss-radio.com.

I sometimes have the same problem with my Roomba 530 (named Ethel). Make sure the signal transmittor on the docking station and the signal receiver on the top of the Roomba are clean. You can use a cloth or paper towel with a SMALL amount of window cleaner to run around both of these signal devices. I also like to clean the metal contacts on the station and the corresponding contacts on the bottom of the Roomba at the same time. This won't make a difference for the docking but it just assures that the vacuum will charge efficiently. If this doesn't work, you might need to have the unit cleaned professionally unless you feel comfortable about taking the unit apart and cleaning it yourself. I did this and Ethel has worked fine ever since!
If this helps, please come back and rate my suggestion!

If you've also power-cycled the unit (turn it off and unplug it for several minutes) and the problem still persists, repairs will likely be required. Service can be obtained by carrying the unit in to the place of purchase.

AM is just another name for MW. The Radio should tune to a strong signal regardless of the frequency the radio is set to. It should also sweep the entire frequency looking for stations. I'm assuming it has a channel scan setting, plus options to set a number for the station. AM/MW are very much dependent on the position of the either internal or external Ariel. If you have the radio in the wrong position or you have some electrical equipment nearby it could block the signal for the station you want, but not affect the others. Which might explain why it can't find the station you want.

It's the dock. The docks pass analog signal through it, not digital, so the hissing is in the background.

check the antenna and see if its grounded out anywhere, like if its chaffed and grouned to the car somewhere. If not try turning on the unit outside of the car or using it in the home dock, if it does the same thing its a problem with your unit or car dock

The unit has an internal antenna (that is really poor) that is activated when you unplug the external antenna. This is why you get some signal when you unplug the unit.

I assume the problem is the antenna itself.

My suggesion is that you charge up the unit, take it to a place that sells XM equipment AND has a demo unit working. Be sure to take your docking station with you (it has the plug in for an external antenna). Ask the sales rep to please connect your unit to an external antenna to test your unit as you are trying to determine if your antenna is bad. If it works, you need a new antenna (cable may be cut on the inside or antenna may have water/weather damage). If it does not, then there is an electrical issue inside the unit and the unit itelf will need replacement/repair.

I also have the same problem but now I think it's the type of I-Pod you use. Do you use the I-Pod 80 Gb video or the newer 160 Gb I-Pod with the cover flow etc. ? The documention of the HTD7001 says it's only support some I-Pods. I would know sure if I would have a type of Video I Pod wich is supported by the documentation

Sirius does not stand behind their products, There is no out of warranty repair for their radios,  and they do not offer sites for repair. Seems  like this is a definite problem with this model. Their solution is to buy a new radio,(with all the new-docking,boombox etc) accessories. also they charge $75.00 to change to the new radio.I liked my sportster 1 because of the FM modulator. It just had to be centrally located and all the radios in my home picked it up(no docking) the new radios require $50.00 docking stations for each stereo location and radio location, unless you bring a boombox everywhere, and the sound isn't the same.    I feel there should be a class action lawsuit against Sirius for these reasons and I might look into it. What do all you think?
