There is no specific dead key setting for an ampifier. Each amplifier requires different dead key to operate at it peak effeciency AND to sound the best it can. If I knew what type of amp it was I could give you a better idea. Just for a reference point I will give you these numbers. For your basic amplifier ( 2 pill - 4 pill non high-drive) you could safely set the carrier at 1 - 3 watts. This is why the majic number for most people is a 2 watt dead key. For a High-Drive amplifier you really have a broad range of settings for deadkey. Generally anywhere between 2 - 8 watts. Some can even handle 10 watts. This DOES NOT mean that they need a HIGH dead key to operate properly. Just FYI, what you run into with improper dead key is either a really choppy, splattery, overmodulated sound with a deadkey that is to low, OR, a really pinched up, tight sound with a dead key that is to high. Also, a HIGH dead key can cause an amplifier to over heat, causing the transistors (pills) to fail prematurely.
To set your dead key "properly" you really should have a technician "match up" the radio with the amplifier. This means, he will hook up the radio and amp that you plan to use with one another in line and tune (set dead key) the radio to "match" the amp. This will give you the optimal audio and performance without overdriving the amp.

check your swr's they may be high. causing it to blow the fuse.

squelch counter clock wise.
volume to comfortable level
rf gain fully clockwise
mic gain fully clockwise.
band should be band d??
adjust echo to decent setting.

check the swr's probably are high if it blows fuse. those should have a 5 amp fuse.

email me i have a generic one that is the same for all exports. ie galaxy 33-99's and connex 3300 superstar 3900's and general lee's style of radios. I thinks its for a superstar 3900 just ignore the SSB & CW portion and its the same radio as the 3300.. any questions let me know

They determine what kind of signal you broadcast and receive - you can communicate only with ones that have the same setting.
AM/FM is the modulation: Amplitude or Frequency, you should keep it on Amplitude if you're in USA or on FM if you're in most of Europe.
D/A , E/B and F/C is the general band selector, it basically makes a selection of the available channels. The general use channels are on the D/A band. Do not select the other bands, you need a special license for them.

1. your unit is defective 2. If under warranty replace asap before your blamed for the damages 3. If the company refuses to take it back for an exchange, contact bbb.org and file a complaint

Try the voltage regulator or the power supply circuit

check your antenna first, you need to adjust it if it's adjustable, if not, then get one that is adjustable. make sure it's also elevated high enough.

What parts do you need? contact us if you need help..

check your mic. antennas swr, and see if they have a problem otherwise it may be an internal problem. make sure the mic connector isn't rotating in the case and shorting out....

there are a dimmer switch on front panel turn it up

check mic or coxail

you will need a frequency counter, to show the channels. 1-40 and the others are allocated as frequencies. there are lists available showing ch1 band A is ??? so forth. there shouldn't be uppers or lower on it its just a AM/FM only radio NO SSB.

and these ARE NOT AMATEUR / HAM radios!!!!!!! these are EXPORTS...

Looks like the webhost is upgrading their server. It will be back up eventually.

Hi jeremy, my name is John. Welcome to FixYa. I think you are saying you are trying two different antenna,s. With the big one, sounds like you have a high SWR. or a bad ground. Make sure that your antenna is grounded good and nothing is blocking it. You will need a SWR meter and a three foot jumper to check this. How to check this is take one end of the coax jumper and run it to the radio and the other end to the meter where it is marked radio. Now take the antenna and put it in the other fitting marked ANT. Set the dial on the meter to SWR SET then turn off all your modulation,MIC GAIN, POWER MIC, now key the MIC and adjust the needle where it says calibrate all the way to the edge of the scale, not going past the edge, with the MIC still keyed up, turn the switch to SWR. that reading you see on the scale is your SWR. If it reads a three (3) or over, it is to high. Depending on your antenna, there are adjustments. Thanks for choosing FixYa...John

Hi, my name is John. Welcome to FixYa. Check your antenna, make sure it is grounded good and nothing is blocking it. Have the SWR checked. They will do it for free at Radio Shack or any CB shack. Thanks for choosing FixYa...John

Hi, my name is John. Welcome to FixYa. Turn your RF GAIN to MAX. and SQUELCH to MAX. If you need further, let me know. Thanks for choosing FixYa.....John
