Your SWR (Standing Wave Ratio) is 1.5 this is acceptable. Now your radio comes with a 2SC2290 final transistor. This produces 50 watts PEP (Peak Envelope Power) But you say you are getting 4 or 5 miles. You should be getting FAR more than this. So this hum could be your problem. What your hearing is a ground loop. Yes, this big of a radio you should run strait to the battery and I would put a 15 watt fuse inline on both the ground wire and positive wire within the first foot of your battery post. A blade fuse and holder is fine. This is what I use. Next get yourself a copper braid strap and ground the radio a second time. Install the braid strap from the radio to a bolt on the passenger side floor board or any other suitable place but make sure it bolts down tight. This is the proper way to install this radio and it should also fix the hum. You may also need to address the microphone if it is still humming but I think this will take care of you.

by Osko Pool n Spa If your Swimming Pool or Spa Pump Motor is humming and/or has very little or no water flow, please follow the following directions.
1) Remove the pump motor from the system.
2) Disassemble the front half of the Pump Pot Housing from the back half.
3) Check for any foreign obstructions which would jam the Impeller and remove it
4) Next, inspect the Pump Motor Impeller itself. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged and requires replacement.
5) Next, remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged and need replacement.
If everything seems to be in good working order, then you need a new pump... not just replacement parts.

I have a 99 ford explorer and there is a grinding sound that is coming from the passenger side that is constant when i drive and it isn't the brakes

4x4 ? how many miles ? jack front wheels off ground and rotate by hand feel for the grind, bad wheel hub bearing? check brake rotor dust shields, If high miles possibly front carrier or pinion bearing. Just replaced front , rear , and transfercase bearings on my 98 with 193,000 mi. And yes,they were all bad $500.00 did labor myself. did rear first as it was humming, week later grind and hum coming from front, then couple days later transfer case was also whinning,humming, good god what a project all that was but today its great and quiet.

What size wire and what size amp do I use to install a galaxy dx95t in my car

I am thinking you are asking about the " power supply wire "....Ultimately this depends on how much power your radio is asking for when transmitting. Usualy a # 16 wire is adequate but # 14 would if you were to9 pump out 40 to 75 Watts and # 12 Minimum for up to 100 Watts which means heavier wire as the power requirement is increased.

I do not have good transmission but good reception

make sure the antenna is tuned for lowest SWR. Make sure if the antenna is a magnet mount that it is stuck directly onto the body of the car. do not put something in between it and the car to protect the car. likewise, make sure the film is in tact on the bottom as the antenna system needs to have a ground to the car body to work.

If its another type of mount, make sure the mount is grounded to metal of the car.

Make sure your dynamic is up. the louder you are with out over modulating the better you get out. If the radio is stock then turning it to full is fine, it will not over modulate.

You can expect about 4 to 8 miles depending on location and your antenna system with a stock radio. 4 watts of output. Hills and other obstructions like trees buildings and such will lessen the range.

You can turn the power up in the radio. If there is a cb shop near by, you can pay them to peak and tune your radio.

If you don't have a cb shop near by, and you feel comfortable going inside the radio you can turn up your modulation wattage which will greatly increase your range.

Take the bottom cover off. Be careful of the speaker wires.

Look for a variable resistor near the back center of the radio marked VR4 on the board. depending on when the radio was maid its either a blue plastic pot or a metal pot. (pot is potentiometer or variable resistor.)

with a small flat head screw driver, carefully turn this little dial all the way to the left. this will increase the modulation output to max. Now you will be putting out somewhere around 12 to 15 watts of swing wattage, or modulation.

put the cover back on. After this, hook the radio back up and you will get out much better. You will notice that people hear you further away.

You will now get anywhere from 4 miles to 25 miles or so again depending on location.

If you were up on a very high hill with nothing around you, then you could possibly talk further then that.

You will sound much louder to other people on the radio too.

If you are gauging your range on truckers, 90% of truckers have had their radio's peaked and tuned at a radio shop. That will get you even more range then just simply turning up the modulation.

Typically costs around $25 to $35.

Humming sound

it could also mean a low fluid problem. I'd check that first.

well 1st a good radio fragile it is but it kicks **** well
well that hum might be something being lose on the board itself
try to poke the board as you have the radio power with a plastic stick see by pressing you can pin pont the area where something might be lose if you feel risky try soldering yourself.
that's how you learn that gelly rubbery substance inside the radio means cratical part of the bord should be play with unless you are a professional no doubt I hope I help you a bit no doubt
