[Yaesu] Fw: FT-840 Freq. stability problem

[qrz_kp4jrs@hotmail.com (KP4JRS - Jose)]

Hello to everyone:

    I got a FT-840 and have some problems with the frequency stability, Most of 
the time when I power up the radio and go on the air the people say my Tx freq. 
is changing, then when in just receiving i can notice this too. But if I wait 
some minutes ( a long count ) It baceme more stable.

    I have this rig for about 3 years. The only mod inside is the instalation 
on the FM unit.

    Understand there is a TXCO-4 unit available as an option, but Im not sure 
if this can solve my problem.


Any comments on this?

Thanks a lot for the help.
