The internal Tuner SWR circuit (T1) has a vari-cap adjustment C1.

The SWR across the meters should be very close when running a resonant antenna, so if you find a large difference in this case, you may want to tweak the C1 vari-cap of the internal Tuner. how far from resonance) you may find the SWR meters read differently (with each piece of coax causing the SWR to be different at different locations along the coax.Īnd most likely any external SWR meter will read a different SWR since its even further before the tuner. The built-in Tuner uses its own SWR meter during the 'ATU' tune process. There is a small amount of coax between the 2 SWR meters inside the radio. Its circuit is located on the PA board and is electronically calibrated at the factory (using Powermaster external meter), and its SWR is displayed on the main PowerSDR screen TX meters.īut if you have the internal Tuner, the Tuner itself has its own SWR meter (see ATU photos above and look for T1). (Note the Flex-3000 has 1 SWR circuit so avoids issues, and the Flex-1500 does not have an SWR circuit built-in.)
