Bad FW vers.-T- (beta with scope) (tr)uSDX

Post by HB9JOI »

The beta-fw is really not good at all : No / or minimal differences between bandwide 3 Kc and 4 Kc. Also if you swich to 2,4 kc the signal-strengh goes down 50% . Next is that the unwanted sideband will not good or not suppressed . When you listen in LSB and swich to USB you will copy the signal like same if would not switched . Make another test : go on 14.074 mc USB and listen FT8 ... if you switch to LSB you will coppy the same like in USB . Normal would be in this case that in LSB the signals should be away . Same is if you copy in LSB and switch to USB ... then you will copy the signal same like in LSB , also without unwanted sideband suppression . It is not recommended to install the new beta-FW (t-Version) , it is better let the fw in version "i" ! The only positive thing with the beta-FW (-t version) is the added scope function . / 73 , Jens / HB9JOI

Hello OM,

this is the wrong place where you commented about the beta firmware! There is an extra topic here.
USB LSB sideband problems are not related to firmware because it is a fixed algorithm. We have had several sideband supression problems due to not good replacement of the standard Tayloe OP Amp LT6231.
If you have problems with bw you should do a reset (press and hold tuning knob while connect to power).
If this doesn't help you should program the bootloader again.
All sounds not related to the beta firmware....

I will lock this topic now. If you have problems please write again in the appropriate topic.
