Jeff, I have the same impression and experience like You! I prodduced a so called level diagramme, see may attachment. Interestingly thsi result was verified on my UBITX: at -107 dBm (=1?V) at the

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

I have a current version of the BITX which I just finished assembling in the case.? It works after some debugging....replacing the code in the Arduino due to a cw fault per another discussion.? It

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
Here is an example of one of the little swr indicators where you just dim the diode https://qrpguys.com/tuning-indicator I¡¯ve used that kind of a circuit as well as the two torrid system others

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.

Re: QRP SWR meter recommendation? #ubitx
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

Re: QRP SWR meter recommendation? #ubitx
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
