Sheesh!? Ok, some of it was me.

They are Bug bang for the buck. And pretty much arrive as promised.

?

There is one decent YouTube video worth a look, which mentions distortion increasing over a few watts.

?

The other practical problem may be using their switching attenuator board with a uBITX, as that board wants to see 5 watts. ?My uBITX is about half that on 10 but there is a pot on the board with some variability. ?I haven¡¯t dialed mine in on transmit yet with because I¡¯ve been driving them with a KX2 hacked to go to 32 MHz and with low enough drive without using an attenuator - I¡¯m using the uBITX as a satellite receiver for now -but I¡¯m hoping to use two BITX with these transverters as a cheap lightweight backpack full duplex sat rig.
