[Elecraft] Err TXF

[Greg - AB7R]

I think this is moot when it comes to TX.  As mentioned by Bill, you can ONLY use 
the 2.7 or 2.8 for the TX filter in all modes except for AM, that requires the 6 
kHz filter for TX (for now).  Setting the BW in CONFIG for either the 2.8 or 2.7 
filter is not altering the filter, rather it determines when that roofing filter 
turns on in relation to adjusting the DSP Filter width with the front panel DSP 
controls.  If you set the 2.8 at 2.8 and adjust the DSP controls from say 3.0 kHz 
down to 2.4 kHz, the 2.8 will kick in when the DSP filter is set for 2.8.
If you set the 2.8 filter BW in CONFIG as 2.6 kHz, then the 2.8 filter will not 
come on until the DSP BW is set to 2.6 kHz.

So if you have the 2.8 set at say FL2, then you set the TX filter as FL2 for all 
modes except AM.  Setting the BW in CONFIG to a lesser value should not affect TX.
