"What is your DC voltage? The KX1 specification is 3-4 watts with 12 volts, so you are close to the spec right now. If you have an antenna analyzer, check you dummy load to be certain it is the same 50 ohm pure resistive load on both bands. Your wattmeter may also be frequency sensitive - many are.
Yes, look at the toroids and the capacitor values in the LPF. Don't push the power too far - the LPF componentscan be stressed with power level much over 4 watts (that depends on the SWR)." Checking power output with a new dummy load shows 3 watts on both 40M and 20M per my W1. Power supply voltage is 14 volts. A check of the power with an RF probe with 14 volts supply showed 6. 7V on 20M and 6.5 on 40M. Values on a 12VDC battery supply were about 1 volt lower. It would appear that both Bands are at the same level. I am wondering if the power difference noted on the W1 SWR meter is a an issue with the W1?
