Re: Any suggestion to improve modulation in SSB ?


 
Edited

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.
