if l2 is not needed at hf can it be omited,or a wire link in its place?.

There is no way to disconnect the antenna from the input. In bypass all the relays are off, so input is connected to the antenna, without any coils or capacitors connected, just some stray inductance

The ATU10's idea of a by-pass, when turned off, apparently is to open the circuit between the xmtr and ant. Is there a documented mod for adding a shunt relay to the unit so the xmtr and ant are

for L1 i got an EPCOS - B82111EC26 - INDUCTOR, 220UH, 20%, 500MA, 32MHZ,can i homebrew something for l2,or for hf can L2 be replaced with just a wire link?.,the inductors i got for L1 were

Hi, Paul L1 T68-43 one or two cores L2 is not necessary for HF I would use like one more L1 100uH

can anyone tell me what wattage rating the 1mh inductor needs to be in the mfj schematic?

Hi. Very high impedance which you have on 14 MHz meaning very high voltage on the tuner elements, you can burn it easy. Installing traps is the best solution .

so the atu cant handle the? impedance mismatch between my dipole and the freq i try to use, thanks for the response. i was thinking that i have made some mistake when i build my kit. but in 60 m the

Hi. No, you have to use traps if you wanna use it on 14 MHz. Too high impedance.

hi, i am finish to build my ATU 100 kit,, my antenna is a inv V dipole, tuned at 7100 khz. i can reach 1:1 in the 60 meter band, but cant reach SWR low than 7:1 in 20 meter band. i check continuity in

thank you to all for the reply. finally i find that really the diffference was low, so its fine using different gauge in the tandem

hi Bill and all the fans arround, I won't bother anybody! Nice answers from a bot... As bot, I first would reply your question as follows: "To give a nice answer, I just have to know the basic values

That SI app should be renamed BARD verbose bot! lol. It may be more useful to pose the question with respect to RF transformers, as the Sontheimer coupler used in the ATU-100 is comprised of two

So, I ask Bard the question and here is what I got back. My questions are in large bold type. The way you phrase the questions and the parameters used greatly effects Bard’s answers. Bard’s

** One would have to plug in the actual parameters to see the actual effect given a small toroid. Give it a try and let me know how you make out. Sent: Sunday, November 5, 2023 11:57 AM To:

So, here is what the BARD chat bot had to say (Some engineering book!). This took 10 seconds. It has been said that a chat bot will never replace an engineer, but an engineer with a chat bot WILL

Hi . It should be the same wires and parts should be mirrored each other.

Try asking the questions in Googles AI chat bot BARD. You will be amazed at what you get back and can learn. Do verify all information. Will save you hours/days searching the Web.Bill, WA2WIO

I doubt that it is all that critical. I know, when winding toroid inductors, that the wire diameter makes surprisingly little difference. Saludos John, VK4TJ

hi. short story i mess the provided wire for binocular winding in my kit and only can build one side of binocular with this wire, i have a similar diameter wire and wind the other side, so my question
