Question about Audio Players & Recorders

1 Answer

Cd quality The quality of  the cd music  on my Bose is consistently inferior to the quality of the music on the FM band. It seems to lack upper frequency response.It lacks the presence and fullness of the FM music. I bought this system perhaps five or six years ago. I am wondering if there is some sort of maintenance I should be doing to improve the reproduction...something similar to a head cleaner I use on my camcorder?

TV CONTROL ON SAME FREQUENCY AS BOSE, HOW DO I CHANGE THE FREQUENCY TO STOP THE BOSE SYSTEM FROM RESPONDING TO MY TV REMOTE


Go through the BOSE manual to see if another channel can be chosen to control the system. If not, try and locate them farther apart and shield the remote with your hand to avoid signal from getting to the unwanted device.

Can the GRECOM PSR255. be used to scan for aircraft /airband frequencies


Your radio is not capable of recieving air band frequencies. It will only receive 4 bands consisting of: 26 - 54 MHz; 68 - 88 MHz; 137 - 174 MHz and 380 - 512 Mhz.

The VHF airband uses the frequencies between 108 (just above commercial FM radio) and 137 MHZ (just below 2 meter Ham radio). Amplitude Modulation ("AM") is the mode that transmissions are made. The lowest 10 MHz of the band, from 108-117.95 MHz, is split into 200 narrow-band channels of 50 kHz. These are reserved for navigational aids such as VOR beacons, and precision approach systems such as ILS localizers

Ihave a gargeled recive sound


Check the position of the mode selector switch. You may be receiving a SSB (single side band) transmission that is not on the exact same frequency as you or, your radio is in AM or FM mode. You will need to select either USB or LSB (upper or lower side band) and vary the clarifier knob until the sound becomes intelligible. If the sound does not become clear, try the other side band and repeat varying the clarifier knob.

Conversely, if you are in USB or LSB mode and there is a transmission on AM or FM, it will have the same garbled sound. Try changing the mode to AM and the FM. If it does not become clear, it is likely a SSB transmission and you are not on the exact same frequency of the transmission you are hearing. Vary the clarifier knob until it becomes clear - or change to the other side band if needed and try the clairfier again.

The short story is that you must be in the same mode and on the same exact frequency. When in AM or FM, this is less of a problem as these are much more wide banded signals than SSB signals.

The 2990 is really a 50 watt 10 meter amateur radio - but is geared to CBer's as it is easily modified to work in the CB frequency range and the so called "free band" between USA's CB (11 meters) and worldwide amateur 10 meter bands. Be careful transmitting this radio on CB frequencies as it violates FCC rules for power output there - and transmitting in the 28MHz - 29.7MHz requires a valid amateur radio license. Fifty watts on ham frequencies is tiny compared to the 1500 watts permitted. Why not get your ham license (here's how) and leave the "Chicken Band" (and all it entails) behind. You won't miss it!

I hope this helps and good luck!

After placing several discs in the bose wave radio


Buy a quality CD radio. Bose is not quality. It is overpriced overhyped so-so quality stuff. Repairs by Bose will cost more than a better quality replacement.

How good is fm tuner reception? We live approx 50 miles from transmitters and have trouble getting clear signals. Is Bose just good sound quality, or does tuner provide superior reception?


I live in Vail Az about 110-120 miles from Phoenix Az I can pick up 60% of the stations decent. The power cord acts as a fm antenna. Plus this Bose Wave CD/MP3/FM

Only in certain areas and passing vehicals cause interferance


I'm assuming your using a RF unit (radio frequency). Whether this unit inserts in the antennea line or is simply broadcasting an FM signal via it's own antennea, it is still transmitting a low power FM signal. The idea here is to find an unused FM channel in your area, set your radio to that channel and program the Sony RF unit to use that channel. The signal the Sony RF unit is transmitting is low power due to FCC regulations and to minimize the possible interference you could cause to someone else's FM listening.

You are likely using an FM channel that is being overpowered by a real FM radio station. This is usually solveable if you only travel in your town by picking an empty FM channel. If you travel alot, the channel in your town that is empty may not be the case when you travel 50 miles away. That's just part of the problem inherent when using radio frequencies to get your music into your radio. You have to be willing to deal with it.

As far as passing vehicles, I'm going to assume that the vehicles that are interfering with your radio are doing the same thing you are doing, they are using FM radio frequencies to pump music into their radios and they are using an FM frequency close to or the same as the one you are using. Since having an unused channel on the FM band is pretty rare these days, if there is one, you can bet everyone is trying to use it for their own purposes since it is "quiet", until you come around!

Bose in France


If you don't have your user guide any more, you can view, but not download it here:

http://products.bose.com/pdf/customer_service/owners/og_awmsii.pdf

Bose has blocked the download of the .pdf file for whatever reason.

If you check it you will see that it is compatible with international AC voltages (220-240) but France uses a different AC receptacle than the US so you will need the correct power cord.
As far as frequency bands; Europe uses much the same for AM & FM but some bands not used in the US won't be available with the Bose.

Because the user is supposed to be an idiot, they have very little detail in their manual besides what is necessary to operate it, they do not specify whether the power supply is auto-switching for different AC voltages or not. Most modern electronics uses a type of supply that will accept anything from 100-240 VAC and that kind of supply doesn't care much what the line frequency (50 or 60Hz) is since they do not use low frequency AC transformers.

Typically, their customer service phone line is answered qjuickly and by knowledgeable people so I recommend you call them with the request for the needed AC power cord and ask them about the means of accommodating French line voltage.

You didn't mention where you live so you will have to check for the proper current toll-free number on page 27 of the online user guide linked above.

Realistic pro 2020 scanner


The Realistic PRO-2052 is an old (vintage) scanner receiver with fixed AM and FM modes on the bands it cover, as specified by the U.S. band allocation. The PRO-2020 covers only the VHF and UHF frequencies and modes AM and FM is not user selectable. Frequencies can be programmed into any of the 20 memory channels

U.S. Coverage: (varies from state to state and other countries. We don't use 30-50 Mhz here in the Philippines for 2 way mobile communications, except for cordless phones)

30-50 Mhz Lower VHF at FM narrowband only (covers mobile, emergencies, businesses, etc. and
cordless phones)
108-136 Mhz Aircraft band at AM narrowband only
138-174 Mhz Amateur and Commercial band at FM narrowband only (2 meter band)
410-512 MHz Amateur and Commercial band at FM narrowband only (70 cm band)

If you're trying to select AM or FM for a specified frequency, I'm afraid you can't do that as it is not selectable.

If you are trying to program AM Broadcast frequencies (mediumwave (MW) or FM Broadcast frequencies (FM radio stations), those were not covered by your PRO-2020's microprocessor. Even if you modify your scanner to receive those bands, you will not hear radio transmission properly since the receiver do not decode FM wideband, which is the standard mode for FM broadcast and Television band.
