Classic band "option"
Hello,
I am a bit confused by the band descriptions. I understand that via the menu system one can choose the classic bands option, but do the different band options require different PC boards, or is the board stack the same for all band options?
Also, I understand the design is optimized for 80-20m, and not to expect great performance on the higher bands. However, does using the classic menu choice degrade the 80-20m performance?
When ordering a kit from one of the listed vendors, does one need to specify which band option will be the one being used?
Thanks!

in the menu you select, what hardware you have, which rf board.

Re: Classic band "option"
Thanks for the info, but I'm still unclear about if the RF PCB is the same for all band choices and only coil and cap values are different or if there are unique and different (different copper traces, vias, etc.) PCBs for the Classic, High, Low etc. bands.
Some web sites I have visited have verbiage that strongly suggest there are significant layout, trace patterns, via placements etc. for the different band choices, albeit, most appear to be non English first language writers, so it may be due to my poor interpretation of the text.

It´s the same PCB for all Variants.
Only Filter caps and coils are different as well as PA Fet used.

Any links for Asia? Sellers of the kits?

Re: Classic band "option"
Good Morning,
As mentioned several times before:
High Band and Classical Bands RF Boards are only available as Kits.
There´s too much tuning involved to provide this assembled.
If anyone wants to provide that service, I have nothing against it, but from my side there are no intentions in that direction. After all: (tr)uSDX was intended as DIY Kit and where´s a will there´s a way.
So: If you really want it, maybe it´s time starting to learn how to solder.

Re: Classic band "option"
I’ve built my kit but it did not come with the 3 PA FETs. Am I supposed to de-solder the FETs from the standard board and re-solder them onto the Classic board?
Thanks.

Hi Kevin, on the rf board, on the opposite side au toroids, you have to see the fet with three contacts already soldered.

Re: Classic band "option"
The IC marked "DB15AB, 86256" is the PA FET?
