Barry , I did but only with white screen, I wonder if I still need to place the resistors , which I did not after the jumper , or maybe the ili9341 needs its own driver like the nextion display ,

My code won't play nice with a v4 setup. It's only for v6.

Re: Separate LPF for a uBitx
I used 4 filters to cover 80 to 10 meters. There are two factors at work
here.
First, you notice, the driver and the PA are push-pull. This arrangement
produces fairly low even harmonics. Hence, a 7

Hi Mark,
Yes. Exactly why I put stars around *good* when I said *good* filter.

Re: Separate LPF for a uBitx
Yes,
However careful filter design is needed when using just four filters.
The obvious reason is that you still need a good cutoff for the lower frequency band.
Not so obvious is that you need to

UBITx V4 using CEC 1.6v Saving Start up Frequency and Mode

Quick question about changing and saving mode for desired frequency. When the unit is turned on, it always goes to program default of 7.150khz, LSB on BFO A.

Re: Separate LPF for a uBitx
Hi,
The real reason. Once upon a time the ham bands were harmonically related. 80 meters is approximately the fist harmonic of 160 meters. 40 meters is approximately the first harmonic of 80. Etc,

Darwin, the picture shows the pads but no jumper. Is this is a 'before' you

Re: Separate LPF for a uBitx
You should use as many filter segments as is necessary to meet your countries regulations for harmonic reduction (whatever that may be). It's not something that you declare. It's done by

Re: Separate LPF for a uBitx
I suspect it's for the same reason as everywhere else.
It's cheaper and easier to only make 4 lpf's as opposed to 6 lpf's.
For example the M0NKA mcHF only has 4low pass filters and it covers 80-10m
