It might be safest to consider using a 3dB power attenuator on the input of the DB6NT transverter, then you don't have to worry about over driving it. There are some inexpensive 20 watt 3dB or 6 dB attenuators on eBay from China that would do, or you could use the smaller more expensive types that bolt onto a heat sink.
If the DB6NT has a common RX/TX IF port then that loss on RX should not matter very much as the gain of the transverter should be high enough to overcome it. It also is better from a transmitted wideband noise point of view to do this, as just turning down the drive level to the 144MHz transverter by 3dB reduces the S/N of the transmitter output by that figure. 73 David Anderson GM4JJJ > On 7 Jan 2015, at 09:10, David Pratt <[email protected]> wrote: > > I have just measured my K144XV power output with an accurate power output > meter and find that with the K3 set for 1mW the output is 10.5W.
