Right I could do that and use it just on 160m. So as is I’m seeing about 2 amps on 80m and it goes down as I switch to the higher bands. So going lower from 80m to 160m I jump over an amp to 3.2amps. It’s interesting and just wonder what others are seeing. I don’t see such a jump when looking at my 2 bitx40’s.

Bill, if you’re worried about your finals just turn the drive back a bit.
Doing some testing with my uBitx on 160m with a 160m LPF attached to the output. I’m seeing about 15 Watts out but the current draw is running very high at just over 3 amps. So not usable on 160m at the finals will blow I’m sure. The bias stays normal
so it’s something else? I wonder what others are seeing?
Doing the same test on my Bitx40 on 160m I see about 10 Watts out and the current is about 1.5 amps and very usable.
Thanks Bill Ng1p

What are you using to connect the filter to the antenna connector on the back of the rig

Very smart. External. Then you can change it to whatever band you want at any time.

This is what I did for my bitx40 for use on 80 and 160. Using the Qrp lab filters
