How do I install a FM radio 180 kHz low-loss filter?

How do I install a FM radio 180 kHz low-loss filter? Topic: Housing case sony
July 19, 2019 / By Nethaniah
Question: I have never opened an expensive radio before, and I don't want to mess up a $150 radio. Is there a way that I could install this into a Denon Tu-1500RD radio (shipping to my house this moment), a Philips radio (forgot the model), or some Sony boom box from the late 80s, with instructions basic enough to cover all of the radios? Perhaps a link with visuals would help; I am a visual and kinesthetic learner. Any help is appreciated, thanks! These filters are at 180kHz so there is no interference from a possible radio station 200kHz away (such as 95.9 and 96.1 may be semi-local and 200kHz apart) I theorize that with this filter, it would show absolutely no interference.

The filter you describe would have to be at the IF frequency, usually 10.7 MHz with a bandwidth of 180 KHz. Most radios for the last 30 years would be difficult to add a filter to the IF without detailed Schematics. In the US, FM stations are strictly limited to distance between adjacent and second adjacent stations, so it would seem you are trying to listen to a distant station while a nearby one is causing your interference. The filter may not help and may make it more difficult since the filter will have losses, meaning the distant signal will be weaker. In any event, if the local stations are very near or very strong they may override the receiver front end enough to make it impossible even with the filter. Your problem may not be adjacent stations but overload from a near by station that may be many KHz away in which case the filter will be a total waste. If that's the case, just try less antenna on the radio and see if that helps.

If I told you how easy it is to get a job in this recession, you wouldn't believe me. But the truth is more employers are going online to find people just like you and me who are ready to work at a good job (one that pays good!). The only thing that makes sense is to stop wasting time driving around all day filling out a dozen applications and going from one boring low paying job to another. I found this site that pretty much matches you up with your dream job that is available in your city right now. I have found it very helpful. Go to FindMeJobNow.com

Receiver removal keys: http://www.amazon.com/METRA-86-5618-ford... Wire taps: http://www.altex.com/16-14AWG-Wire-Tap-S... Splice the wires from your aftermarket Sony to the vehicle wires as follows: Yellow - Constant 12V+: Light Green/Purple Red - Switched 12V+: Yellow/Black Black - Ground: Black Orange - Illumination: Red/Black White - Left Front Speaker (+): Orange/Light Green White/Black - Left Front Speaker (-): Light Blue/White Gray - Right Front Speaker (+): White/Light Green Gray/Black - Right Front Speaker (-): Green/Orange Green - Left Rear Speaker (+): Tan/Yellow Green/Black - Left Rear Speaker (-): Gray/Light Blue Violet - Right Rear Speaker (+): Orange/Red Violet/Black - Right Rear Speaker (-): Brown/Pink Seal off all other wires with a wire nut or electrical tape to keep them from shorting.

Go to walmart. Buy a radio dash kit and a wire harness. That's basically all you need. You can look up vides on youtube to help you install it. Oh, you may need to buy din tools to remove your factory radio.

Why would you need one? FM Radios are 88-108 Mhz...no where near 180khz. EDIT: You want a filter 180Khz WIDE, not on that frequency. You may want to try a directional antenna to minimize the adjacent channel interference.

Hum Originally Answered: I needed an FRS Radio, is there a difference between a marine radio and a normal 2 way programmable radio?
A marine radio is for use over water *only* (yes, you might get in trouble for attempting to use it for land to land contacts). It is VHF (30 MHz to 300 MHz) and will not communicate with FRS units, which are UHF (300 MHz to 3GH). Most handheld units, whether FRS, VHF, or UHF (and it doesn't matter if they are ham units or FRS) will generally not be usable for more than about 3 to 5 miles between handhelds over flat terrain. This is due to the curvature of the earth and there exists a formula which can give you a pretty good "guestimate" as to their range. That formula is to take the height (in feet) of the antennas and double that number. In the case of handhelds, 5 or 6 feet is about right. Now take that number and double it. Let's use 5.5 feet doubled, which is 11. The square root of that number is the distance in miles to your radio horizon. The square root of 11 is between 3 and 4 (closer to 3). So long as your radio horizon intersects with another station's radio horizon, you can communicate. In this case, another handheld would have a radio horizon of 3 to 4 miles. You may well be able to communicate with another handheld for 6 miles. Getting a higher antenna (standing on top of a hill, for instance) will improve the situation considerable. Although my handheld antenna is but 5 or 6 feet off the ground, the repeaters I communicate with are often hundreds of feet off the ground. If a repeater is located atop a hill and has a tower that puts the antenna at 200 feet above average terrain, doubling 200 yields 400 and the square root of 400 is 20. 20 miles to the repeater horizon plus my 6 miles would indicate that I can use the repeater some 26 miles away. When I was atop a 23 story building, I could communicate with repeaters over 100 miles away. The building was on ground 600 feet above local terrain plus the 23 stories plus the height of other repeaters. I chatted with another handheld over 100 miles away. 27 MHz CB is different as F layer (or sporadic E layer) propogation can come into play. Then openings can occur over thousands of miles (although the are not legal in the United States). For what it is worth, power is not as important as some think. It is the antenna and (at VHF and above) elevation. 2 amateurs succeeded in communicating via moonbounce (bouncing signals off the moon) using under 100 watts. The moon is some quarter of a million miles away and the signal has to complete the round trip of half a million miles. 85 watts. Go figure. You might consider MURS, a VHF offering that is license free and offers very little interference (unlike 27 MHz CB). You could get your 6 miles between handhelds or perhaps 20 miles between a mobil and a base unit. For longer distances on a consistant basis, about your only legal alternative would be an amateur radio license (no more Morse code!!!). I have included a URL. You can do a search of Yahoo groups to find a number of amateur radio groups, some devoted to helping swls, cbers, and others in obtaining their first license as well as others in upgrading their license. For me, six double a batteries has been sufficient (with the aid of one repeater) for a nice chat (all rf path, no internet involved) with Australia. On FM. Hope this helps ;) Best regards, Jim

The answer is NO. Marine VHF radios operate on fixed channels that have the same frequency world wide. Shore based walky Talkies do not operate in the same way. For example the unit that you are using on chanel 2 will not pick up say police radio channel 2 or possibly a truckers channel 2.
