Can someone explain the reasons for certain voltages listed on any schematic for the electrolytic caps, AND what problems could arise if one used a cap with a larger voltage rating? How much higher a

Does anyone know if overheating the finals causes damage to them if on cooling they still work........ I would wonder if the output is the same as when they were new. David J. Wilcox K8WPE’s iPad

Thanks everyone. Will get a low cost scope and do some looking around in my QRP rigs. David J. Wilcox K8WPE’s iPad

Tom, I guess I need more hand holding and pictures. A friend came over with his new Rigol scope to help me once and and had a slew of attenuators, tees, and other stuff so he didn’t wreck his scope. I

Has anyone information on how to use the Digilent analog scope? The reference manual reads like a college text book on its features but using it for ham radio testing for a newbie I need a simple book

Mike, It worked for me and Farhan responded telling me my parts were on the way. David J. Wilcox K8WPE’s iPad

Where else do you find service like this? This reminds me of the good old days when I moved to Traverse City to start medical practice. Most of the business was conducted with a hand shake...... even

Is anyone considering ordering the parts for the Antuino fix and selling them in sets for those of us who don't have an SMD junque box? I would be interested and have two friends with the same problem

Go to their site https://www.chipquik.com/store/index.php?cPath=200&osCsid=oc5hv5lc22pbqnp10ch8dmle16 And watch their videos on all their products. Miracle stuff. David J. Wilcox K8WPE’s iPad

The Antuino that Farhan sold at FDIM comes in a metal case. I have no stray RF in my shack..... all xcvrs are turned off when using the Antuino. Mine runs from internal battery power so no power suppl

I have experienced the same thing and at times thr SWR just jumps all over. I keep resetting it and calibrating it and when it does settle down it is solid and gives the same results as my other meter

Wear a mask with good ventilation. Neither the dust from grinding off the paint or the fumes from the paint remover are life extending. Dave K8WPE since 1960 David J. Wilcox K8WPE’s iPad

If you are like me, the FG-01A is the “berries” for antenna tuning and SWR. The Antuino has other uses that may be useful for the price. Mine is flakey in its operation so more trouble shooting or wai

If the screen is all “light” or “dark” if may just need adjustment of the control pot. There is a small pot (variable resistor) on the back of the screen that I had to adjust to get a better appearing

Here is a start: https://n2htt.radio/ You may have other problems but check out Mikes note about the power connector. Also he may be able to help. I have had other issues and will continue to tinker w

Farhan, I just re read the limited instructions on the Antuino and it only addresses the “return loss” calibration. You left out a sentence about the “frequency calibration”. No where does it say to c

Sacha, This is a HOBBY! Mistakes are allowed. It makes a good tale to tell to our friends over coffee. I once bought a sealed lead acid battery at a swap and in the heat of the night hooked it up back

Tried mine last night after fixing the power jack connection. It shows 1:1 on any and every band no matter what antenna is connected to it or if a tuner is used no matter where the tuner is set. Also

Re the screws sticking out I am more lazy than some.... just removed the screws and glued the battery box in place with E6000. Works for me. David J. Wilcox K8WPE’s iPad

Bruce, I was going to wait until tomorrow but quickly checked the solder joint at the power socket.... and like yours even a good looking solder joint was faulty. Especially on the top of the board it
