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

Bill, I guess you are right.? I ought to be able to do some experiments before we leave to get a sense for how the MFJ performs at low power.? If I can understand what readings correspond to 2:1, I

Re: uBitx low audio all of a sudden
UPDATE I found the low receive was due to a bad NANO. I have a spare Raduino board and put it in and it worked, replaced the NANO on the other Raduino and it worked. Problem now is? I have no XMIT
