does it do his on the other bands also? Check your heat sinks in the area to see if they are also hot.the hottest one is probably going to be the culprit .Now find out what is on the sink and back step from there until you find out why that sink is getting hot.

cut back on the power,turn up the modulation and you should be good.

open the fuse holder in the back of the radio get the number off it. It will probably be a 5 amp fuse but whatever ,replace it with the same one.

All radio's are factory set up and although you can tweak parts, this is usually at the expense of longevity or reliability.
To tweak a radio properly and ensure it remains legal, you will need the service manual, an accurate frequency counter and standard, a nice dummy load and an oscilloscope. If you turn anything inside and do not know what you are doing, you could end up stressing output components due to signal mismatching and possibly end up with spurious transmissions which can interfere with other electronic equipment.

The size of the wire is determined by the load it needs to safely carry. This can be obtained from the manual or the supplied fuse size. Once you have found this value, multiply it by 1.25. This means a 10 amp radio will be 12.5 amps. A 30 amp radio becomes 37.5 amps. A 60 amp radio becomes 75 amps - and so on. This is REQUIRED to prevent the wire being used at 100% of its capacity, which would cause it to heat up. Enough heat will cause insulation to burn. Insulation comes into play below. Use the chart linked below - and use copper wire.


In order to use this chart properly, you need to determine the insulation type. Different types affect ampacities of the conductor. Typical "romex" wire (the stuff in your house) is rated for "60 deg C (140 degrees F)". Specialty wires THW, THWN, USE, XHHW, THHN etc. are rated at "75 deg C (167 deg F)" and / or "90 deg C (194 deg F)" and have a higher ampacity for the same size copper wire than "60 deg C (140 deg F)" wire as a result. If you do not know which insulation type you have, assume the lowest "60 deg C (140 degree F)" type. Look up the amps you calculated above for your particular radio in the "60 deg C (140 deg F)" column, otherwise look it up under the column with specialty insulation types instead. If the CALCULATED amp value is NOT listed, pick the next LARGER value. Follow it back to the LEFT most column to learn the SIZE wire needed with the same insulation as listed in AMP column.

If your radio was 48 amps, it calculated to (48A x 1.25) = 60A. If you don't have the wire, you can go to a store and say you need 20 feet of #4 copper wire with "60 deg C (140deg F)" insulation, -OR - #6 copper with THW, THWN, SE, USE, or XHHN insulation - OR - #6 copper THWN2, THHN, XHHN2 or USE2 insulation.

The values above hold true regardless if in a circuit that is 6 volts or 600 volts. You should increase the wire size (lower #) on DC circuits only if the circuit length is 50 - 100 feet or more. AC circuits can be hundreds or more feet long before increasing the wire size is needed.

I hope this was helpful & good luck. I hope you've got a ham radio license before you transmit with that radio in the 10 meter band.

there should be a knob on the face of the radio that says talk back. Adjust it to your liking but not to much so you don't get feed back.

Ranger Radio... | Answered on Nov 04, 2013

some Rangers you can go to their site and get the information.I would google it then search for what I need then use that information.

There is probably a blown capacitor in the thermal protection circuit causing the cooling fan to run constantly. Unless you are an experienced electronics technician you probably need to take this to a shop to get it repaired.

Ranger Radio... | Answered on Nov 01, 2013

did you try LSB. Maybe the band opened up for you.sniff around to smell which one blew and replace that one .if there are two together replace them both.
