The SWR is measured by the T507 and the components around it - you could check carefully to make sure that none of the nearby components has been disturbed.
SWR is also affected by the efficiency of T501 and the Low Pass Filters.? Differences in the low pass filters, such as soldering issues, component tolerances, and parasitic resonances can also affect power output level and SWR.? It would probably be good to check that only one of the LPFs is getting switched in as the bands are changed.? Easy to do this by measuring the 'line end' of the diodes: they should have a voltage (5V or more) for un-selected filters, and be 0V on the active filter.? If there is a short that is keeping one filter active all the time, even when another is switched in, could affect SWR on all bands.?? Since the SWR is high on all bands, the main issue is more likely at or around the 'choke' points where all the bands use the same hardware, which is the circuitry around T501 and T507.
In the diagnostic screen, is your PA bias drive at 30mA as it should be?

Good luck, Stan
