In the setup there is a "extended" mode how do this work ???

why I am asking is becource I would like to use Thetis on the 8m Band (40mhz) I can see that my TRX-board do TX on the 8m/40mhz, but my
BPF+PS-board do not allowed the RF pass true

Go into Setup > General > Ant/Filters, then on each BPF tab select all the bypass options.

HI Scott

so if you enable as I did (red ring) in the 2 menu you have RF out on 40mhz ???

Oops, my first answer was wrong!

All of the various controls and settings marked "bypass" are only useful on receive, and only bypass the receive preselection aka bandpass filters.

The transmit LPF filters can't be bypassed. However, not to worry. The 6M LPF cuts off well above 40MHz, of course, and it is automatically selected when the transmit VFO frequency is between 35.6 and 61.44 MHz (assuming the default settings have not been changed in Thetis). Unfortunately I don't think anyone has measured filter response curves for the LPF's, so there's no exact data on them.

Remember that all of the BFP and LPF filters are hardware and are not programmable. The frequency ranges shown in setup merely reflect when each is chosen.
