Magnum Delta Force distorted SSB modulation when cold.
 

My radio does not like low temperature. When cold (e.g. less than 50
deg. F), the SSB modulation is bad. Its a sort of brumming noise
superimposed on the audio. Strange, if I change to AM or FM, the
modulation is good, under same low temperature conditions. So, it
seems that the microphone is OK.

What I do now is to heat the radio using a hair drier until the SSB
modulation is OK. In a cold room, I need to do this every 15 minutes
or so.

Any ideas of what causes this, or how to fix it?

Thanks,

Julian

Sounds like maybe an oscillation. In any event... this sounds like a
job that will require a scope and schemetic. I don't see that you have
any other choice but to take this one in for repair.

Explain the word Brumming. Is it synonymous with vibrating?

Superimposed or additive?

Yes, I've heard of this problem before. You're too friggen stupid to own
a radio like that, so just throw it in the dumpster before the FCC fines
your retarded ass.

**** off you dirt bag faggot

Magnum Delta Force distorted SSB modulation when cold.
 

The distorsion is superimposed on voice, rather than additive. Its
like the voice becames modulated and distorted. Reducing the
microphone gain does not help. As under the same conditions, the AM or
FM modulation is not affected, I wonder whether the SSB modulator has a
sensitive component.

Explain the word Brumming. Is it synonymous with vibrating?

Slow it down mister policeman, SSB modulation is LEGAL in my country.

Most likely the voltage regulation to the vco is being compromised.
