Re: Intermodulation Performance
Hi,Warren, I will always appreciate the data that you generated! Nicer radios, are certainly nicer radios! Some people like Honda FIT , some prefer a high end BMW! For the purposes of coaxing local

Re: Intermodulation Performance
I am finished. This is simply not worth the effort. The difference between this radio and my FT-817 is about $350. The difference between the uBitx and my HobbyPC RS-HFIQ is $100. Both are worth the

Re: QRP SWR meter recommendation?
#ubitx
If you look at the schematic of your tuner, there is probably one or two resistors in a voltage divider chain that you could parallel something with to increase the voltage that gets to the meter.

Here are some code snippets from a project I did. It calculates SWR from the voltages read from analog pins A6 and A7. It does a number of other things, so here are the basic pieces of code for SWR

Correct, no meter provided. A DVM is sufficient. Or could go into analog pin A7 (with an analog switch to select forward/reverse) of the Nano.? Perhaps both A6 and A7, use D0,D1 for the keyer if you
