At a pinch you can use 5 x LR44 button cells, yes that does add up to 7.5 volts but that's near enough, the 5 cells on top of each other are exactly the same size height and width as the 7 volt battery. I am using them in a "Telex" mike

I believe that your installation is faulty. Check for any shorts, solder bridges, and that instructions were followed correctly.

I can recieve but i cant transmit have new antenna and new mic

Check that your mic gain or dynamike knob is turn clockwise if it is full counter clockwise you will have no modulation with your tx power.
I would like to help but one sentence describing your problem can lead to a vague solution.
Be aware that not all 4 pin mikes are wired the same.
1- Shield
2- Audio
3- Transmit
4- Receive

Old dynamike plus wiring for a super star 3900

Check the mike plug to make sure that none of the wires have broke off.I would also check the mike cable with an ohm meter.

Cant transmit out

Not really enough info to help you, but you MUST check the SWR of your antenna system. I've seen many cases where the antenna studs were incorrectly installed, shorting the antennas to ground. Also, make sure the Dynamike control on the CB radio is turned fully clockwise.

Works sometimes and sometimes it doesnt.

Sounds like a "cold" or broken solder connection on the PC board.
