modulation. SSB transmits good I am receiving and transmiting on SSB, but have no carrier signal or modulation on AM. What can I do? I have searched an repaired cold solder joints and checked final on

...modulation SSB - single side band. If you have SSB, there would be a switch on it to transmit in SSB. If not, it is AM only. Second, Has this radio been worked on to be able to run on an amp? If not, ...

...SSB has low forward swing with low modulation?? I have checked many voltages in the past and all that I have checked seems normal. Using SAM's Photofact. Re-align transmitter as per Sams with 2-tone ...

modulation on ssb usb/lsb.receive is alright.checked mic insert -inside mic etc and other end mic plug all ok their. It looks like you had some loose connections in that CB. you may want to also check

modulation out check the obvious first. Is the mic plugged in and tightened all the way. Yes , take the bottom cover off and turn up the variable closest to the small transformer. Thats the modulation

...output on AM with no modulation swing. then change the Audio transistor. SSB should work. they feed straight through to rf final. if no modulation on either mode, then check the mic, audio ic

...modulation OK. SSB is distorted with low modulation , higher modulation seems to make it better but not consistantly . Used dummy load , BK CB tester w/2 tone and 100mhz scope . Looks OK when tested ...

...modulation on ssb or am audio amp ic ok no pa? audio How are you testing the audio out? Are you using another radio? If so, are you REALLY sure the other radio is ok? If the other radio is ok, how do ...

...SSB (with out speaking). This reading is on the radio's built in meter as well as on my Radio shack SWR/Power meter. I noticed that in the modulation setting the meter acts the same way. Also, on ...

...modulation on am It does on ssb but just a carrior signal on AM. Please help! thanks ,Bob Start with checking electrolitic capacitors...radio is OLD.....check caps. for shorts then check Audio Output ...
