Static Can get only static on FM, buzzing on AM. Have had unit only 3 months. Same situation when used in different states.

Sounds like the "set point" is set too low. If they are sending out same Tech every time... Well get a different guy. This should not be happening something is defective it's new you should have MFG warranty contact them to send out new tech. Hope I helped

Try some standards -- unplug EVERYTHING, and use the headphone out jack first. After 2-3 minutes, and it's still crackle or buzz, then it may be something wrong with the internals. Could be simple, but may be more than what the unit's worth to fix. If it DOES NOT crackle/buzz, then you might have a bad connection/cable somewhere. Just plug them all back in, one-at-a-time, and wait in between plugging in. Best of luck!

it's obviously getting interferance fronm that whole house broadcast unit (not abnormal!) best and only thing you can do is to move the stereo to a place where you can get the MOST am stations the loop ant. is exactly what it says it is a loop of wire with two ends..both ends connect to the ant. input on the back of the unit..however if that whole house broadcast unit is the devil then an ant. no matter what or how it's made will only recieve more static not built to reject static! so you've got to move it unfortunately ..fm is a totally different band obviously fm isn't being affected by that whole home broadcast unit..you're lucky! on that count

The only change you need to make for the 120 operation should be to change the fuse to a 2 amp fuse. Faint static is typical of the electronic noise of amps... as long as it it is faint. The power supply will act differently on 120 than 240... probably takes a brief more time to get the system stable, hence the initial buzzing. As long as it performs don't worry about it.

Under menu, select FM frequency. Try using different frequency. A nearby FM station could be bleeding its signal onto the FM frequency your unit is using by default.

Loud buzz is usually caused by static and radio interference in radios. If none of this is affecting you unit presently there there is a probability that some cables which aid the fm antenna in receiving stations this could act as static which brings about the buzz on the unit. Either way it is caused by interference on the fm receiver end and all you have to do is get that serviced and the problem is solved.
Hope this solution has been helpful?

First, you have to find out if the intereference is coming from your power supply or your FM radio. Are you listening to the Stiletto2 on your car FM radio? Is you car FM antenna visible? First try using a different FM frequency - that is the most simple fix. Second, if you car radio has an "AUX" input jack, use that to eliminate static. If the interference is from the car ignition, that is most difficult to eliminate, but you can try a clip-on ferrite ring on your power cord.
In summary, try a different FM frequency, 2nd, try using an AUX input cable, and if you've done either of those, then the noise may be in the power. Make sure to turn the AUDIO OUPUT level of the Stiletto2 all the way up so that your car radio won't have to be up so loud. Go luck, and let me know if this works for you. Happy New Year too!

The "hard wired" version that you speak of apparently only refers to the power supply.Do you have a seperate display for the Sirius unit? Now, you failed to mention the type of radio (factory or aftermarket); so, if you have to use an "empty radio station" then you have an FM modulator. This modulator could wired or wireless. The wired version interrupts the vehicle antenna wire and the station on said modulator is usually preset to either 88.1, 88.3,88.7, or 89.1. There is no need to power this modulator up, it comes on when then Sirius comes on. One way to check for power is to turn on the Sirius unit and tune your radio to an occupied Fm station. Wait a few seconds and listen to the reception. Turn off the Sirius unit, the reception should improve for the occupied station. If it is a wireless FM modulator it also has preset stations that you can change but, extending the wieless antenna will greatly improve your reception of the Sirius stations.

Are you using the FM modulator? Try using a different FM frequency, or use the 'audio out' jack and a cassette adapter. If you plug headphones into the unit, do you still have static?

I have noticed various changes in my invehicle FM reception as well. There should be a external antenna that came with your car kit. This is precisely for these types of issues. It is designed to run along the windshield inside the car closest to the Cars radio antenna. It should plugin to the bottom of the cradle. Then tune it into a clean FM station (one that has no local station on it) and position the cradle and/or ext. antenna till you get the best reception in your vehicle. It could very well be that the antenna has come has loose on your car stereo backplane. You would probably notice decreased reception on regular AM/FM stations as well though.
Your wifi reception/functionality is a completely different animal and has no bearing on the FM transmitter in the car cradle. When your on wifi your not receiving signal from a sat. anymore just simply streaming internet audio like your computer.
Good luck.
