Any suggestion to improve modulation in SSB ?


 

Hi,
I'm trying to have some QSO in SSB .
I? had? some? but most of people I talk to? is telling me? to improve modulation .? I 'm using the original mike arrived with radio and as? settings? I have:

COMP ON? level 1:6?
EQ? ?ON? ? (Bass , Medi, Treb? ?all? ? 0 db as default)

In your? experience , which setting should be the best for optimal modulation in SSB? ?? Is there anything else I can set to improve? modulation ?

I didn't try the internal mike so far, under the assumption that should be worst than the external mike.
Thank you for any? suggestion.

Maybe your audio is just too weak (quiet) and they can't hear you well.? Try increasing the mic gain.

Hi,?
when use more than 1:4 compression I got complaints too. So try to use not more than 1:4.
I opened the Mic hole a bit and filled the Mic housing with foam.?
No complaints anymore.
BTW EQ is for RX only ?

Hello
thank you to all of you for having shared your experience for this topic. In the meantime I've performed some test:

1) I utilized the X5105? few hundreds meters far? from a friend of mine who had another TRX (FT-857)? , who confirmed that my? modulation was low (meaning that the cause of low modulation noticed during QSO with others? was not a low? signal )

2) in order? to avoid boring my friend I started to make some test on my own at home using the X5105 as TX? at extremely low power? and using another TRX (FT-710)? as receiver ( 2 antennas? , positioned at opposite side of the house) and listening to myself in the headphones.? Here under the best setting I was able to obtain to have a good? modulation:

MIC/VOX menu? :? G-EXT? 40? ? ? ?G-INT 50
COMP:? ON? ?1:4? ?( I do confirm that exceeding 1:6? distorsion is detected)
EQ :? ON? ? 4db? BASS? ? ? 2 dB? MED? ? 6 b? TREB

but? most important is the position of the mike in the hand:
45¡ã? ( not vertical )? and? not too? close to the mouth? (10 cm? or more)

I did also some test with internal mike. Surprisingly is not bad at all.? ?20 cm far from mouth? is? ok

Hope the above could be of some interest.
Thanks.
