How do I increase the modulation on a midland 1001 z cb radio


There are microphones with built-in amplifiers that can be purchased to increase modulation on rigs that do not have internal adjustments for microphone amplitude. Another approach is to try and find the service manual for your radio and see if it has procedures for setting the modulation.

How do you turn up the power on a midland 1001z


have you ever listened to a radio that 4 channels away and you have to go to that channel to hear what they are saying and they sound great? Well actually they don\'t because if they did they wouldn\'t be splashing you 4 channels away.A cb radio is supposed to put out no more than 4.5 - 5 watts max. thats because you will be the one doing the splashing if you turn it up to much.For one thing not only do you have to turn up the modulation and the power but also the voltage it takes to operate the radio at the higher voltage and this is the killer ,you will still sound better at the lower voltage but you will have no voltage to run the power so now its not activated so you turned it up for nothing.

Garbled modulation midland 1001z. I would like to be able to adjust.


the ANCE is DM1. you can adjust the.modulation by turning it. you can also just back the Mic gain down until the aaudio is cleaner.

Modulation on 1001Lwx midland cb low need to know which pot to adjust


hello,
The limiter is what limits the modulation. Often times there is a pot that you can turn to adjust it. To get more power and swing out of your radio do this DM1 is the mod limiter RVM1 is the mod pot. Adjust this for maximum modulation. Spread the coils marked Lt5/LT12 just a little Spread LT7/LT11 a lot.

Midland 40 channel 1001 CB radio. I can talk and receive with other units as long as they are close (maybe to 200 meters or so). After the signal gets a bit weaker to where less lights lite up, I can see...


The light you see lighting up dictate how much power you have on transmit (TX) and the strength of your receive (RF) The more lights on transmit the stronger your signal. The more lights lit up on receive dictates how hard they are hitting your radio. Either by power or distance. Is this setup in your car or at you home? Many use a mobile CB in there home off a power supply. Either way I am very concerned about you only getting out a couple blocks. I will help you fix this. First your antenna is a major part of your set up. Spare nothing when buying this. I recommend Wilson 300 or higher for the mobile and IMAX 2000 for home. Some Wilson antennas tune and some don't follow the instructions that come with it and ask me if you are unsure. A good 50ohm coax is necessary too. RG58 or better. For just the CB in the mobile RG58 will do just fine. Now we get to your SWR (Standing Wave Ratio) which deals with return loss and reflection coefficient. To high of an SWR and you will lose a lot of your signal and you can burn up your radio. Your radio does not come with an SWR meter so you will need to purchase an SWR/watt meter and put it inline. The coax from your antenna will run into your meter and then run another coax from your meter to the radio and follow the instructions on how to adjust and check your SWR. So now we are at the point where your set up is properly set up and now to tune that radio up. These radios do not carry much power or have much modulation. The limiter in your CB is what limits the modulation. In your CB there is a pot that will adjust this. Here is what you need to do to get more power and more modulation out of your CB. VR2 is the modulation pot. Adjust this for maximum modulation. Now spread the coils marked LT5/LT12 just a little and spread the coils marked LT7/LT11 a lot. Being a new radio it should not need a receive adjustment at all. Moding the receive includes jumping the PLL and I don't recommend that. You may try to replace that potentiometer but outside of this and the steps above you should have a great CB when completed. Good luck, this should fix your CB set up just fine.

Modultion less than 30 percent.,some one said,,rv201,,but thats hear say,,want to be sure,,


Hi, you will have to put it on a modulation meter to tell for sure, turn your mic. gain to max and see what happens....hope this was helpful....

Symptom:Buzzing or motorboating sound in either the transmit or receive.
Problem: TR602 is oscillating
Cure: Replace C602 with a .01uF cap {Cap is located in the power supply board}.
RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.

Hi yes it is possible as is anything if your willing to pay for the conversion , it would require new chrystals and resetting of the If system but is possible . However porobably not economical Midland did do The 100 model in an Fm modulation format and you will probably find still available on Ebay or Amazon if not that paticular one a good version at any rate ..I beleive they did actually do an Am Fm model also ...Regards Vortash
