[RTTY] Twin-Peak filters

[Doug Ferguson]

Has anyone been able to use the twin-peak filters with the lower tones on
any

of the Icom  radios or any radios for that matter. I have an IC-7000 and the
TPF

switches off when I go to the low tones but my hearing is very poor at the
range

of the regular high tones.  I like to tune by pitch rather than using the
MMTTY visual

tools - its much faster.

Thanks,
