hey ramblin man on the galaxy dx-44 i put another new audiochip in the way you said it goes in i can transmit,modulate and needle on my meter shows i,m recieving people talking only problem is i still cant hear anything everything else seems to be working except for the audio i tryed the factory speaker,an exteral speaker but still no sound could i have shorted something else out when the chip was in backwards awaiting your wisdom

hey bud,you need to change the shunt capacitors in the audio chip area. its always a good idea to change these,when you have to change the audio chip.especially in your case as the adio chip was installed backwards.change c-150,c-151,c-146 and see if this will get you up an going...also check c-190,often this cap.goes bye bye when a radio is hooked up backwards.which is basically what happened,installing the audio chip backwards........and as far as the talkback,in your galaxy saturn.this is a real easy mod.clip d-80.if you want to make your talkback switchable.install a spst toggle switch in series with this diode,one wire to diode,and other wire to the wire next to board where you clipped it.also you will need to install a 470k resistor from the junction of c154/r207 to the junction of c187/r235 on the solder side of the pc board.to see the location to install it...go to www.dxzone.com/cgi-bin/dir/jump2.cgi?10=2482 ramblingman

hey,that web site aint gonna work.try http://home.earthlink.net/~galaxytech/l ... lkback.jpg

ok thanks for the info do you run a cb shop or something if you dont you sure ought too

ok on the caps do they go in a certain way i noticed a negative sign running down one side do they go in with the neg. side pointing a certain way or just go in anyway

are the circuit board parts on a mirage 88 the same as on the dx-44 if they are i,m missing c-190,c193,and r-243 the resistor behind c-193 and tr-52 if this is right do you know the part numbers of these missing pieces

my 44 doesnt have a c-190 and i,ve never taken it out is it supposed to have a c-190 my dx-66 has a c-190 and no c-193 my mirage 88 has a c-190 and c-193

hey it should be the same board.whats is the pcb number for the mirage 88.i pretty sure it should be a ept360014b.check it out and get back too me.

yes the 44...66,and mirage 88 are all the ept 360014b board but the 44 is missing the caps i told you about its like they were never there ..should i put the missing pieces in the 44 ...nobody has had it since it was new but me so it came like that with those missing pieces

hey,they didnt install them on the solder side of the p.c.b. did they.ive seen some radios with the small can capacitors,installed on the solder side of the pc.b.

The reason the components are missing is that your Galaxy 44 is AM/FM mode only. The missing components are only fitted to radios, which have SSB.

ok thanks there rick i was worried there for a minute i bought all the caps ramblin man said to replace today i hope it fixes the 44,66 and 88 i,ve been without them for a couple of years now theres a place near me called randolph and hale where you can buy only certain caps,resistors that you need instead of having to buy a whole pack of different values...i,d give anything just to be half as smart as you and ramblin man you two guys are my hereos

by the way what exactly is fm mode i,ve never used it anyway is it any better than am if your buddy has fm too

hey,try changing the am detector diodes d-23 and d-24,if no help try lifting one leg of tr-39 and see if reciver audio returns.....ramblinman
