And the winner is: The female header method -- Tried this morning and it worked great. I inserted the one pin male into a three pin female and was easily able to solder the one pin headers. The female

I did mine as seperate windings for 40m worked out fine Nigel M0NDE

Advantage of having all the discussion in this group is that all the discussions are in one place and available to everyone without having to chase all over the Internet.? Disadvantage is that all

after winding my 40m T1 as the manual suggests i had nothing but an uncountable mess on my hands! so i wound them separately, putting a tiny dab of hot glue on each one as i finished it in order to

Michael Maybe distributed capacitance? Not sure how the meter works but the actual inductance is not usually measured, just the apparent inductance. As far as resistance goes how do you get anything

I counted turns as I took them off of T1 P1, S1, and S2 - 5 turns S3 - 59 turns. I removed 10 turns from the Toroid to bring C1 into range so I apparently over wound it by 1 turn.? Unfortunately I

Personally, IMHO, the world is on fire with FB social media. Easy to attach photos to your post and have a nice GUI for the thread. Forums are kind of old school and a thing of the past. It looks like

Yes, I see no point either, it is all together here. Why make another place to search and ask? 73 Alan G4ZFQ

I agree.? Do not split the group.? It will just make it more difficult to find things. Paul K0ZYV

Hi guys, I took three goes to get mine correctly wound and installed. I have no excuses other than age! However here are the lessons I learned along the way since I wound my first one back in the mid

I saw altitudes dropping and was hoping it collected moisture but would dry off and rise again...who knows...anything can happen with these things. Would not be a first . Optimism always high in this

I have not received my QCX yet but when I read the procedure for winding T1 my thought was why not wind each one separately?? I have built a lot of kits and wound a lot of toroids and that seems to

Hello John, Whilst appreciating your good intent I see no purpose dividing places to discuss QRP Labs products. I am a member of the Kenwood TS-590 group that spawned a second group, and that is in

After much "wailing and gnashing of teeth" I decided to remove the transformer (T-1) and re-wind it. It seems like T-1 is the logical culprit for low receive gain and the inability to adjust C1 for a

Totally pointless in my opinion. Why? 73 Roger G4IUP

Personally I don’t think that’s useful. 73 Keith G6NHU

What use it is to split the group? None at all I think. And why can I not reply to the annoncement, but have to start a new topic? Jan

Check solder connections on rotary encoder. I had same problem - no response to long press- found that I had forgotten to solder two pins.

Pin 19 has about 300ohms to ground. If I pull the IC the pad is infinite to ground. John Mazzone N2EIK

It's definitely? a trial in self restraint, LOL. The hand drawn diagram is great and lays it out very well but one does need to be quite dexterous and patient. Hold the coffee until you are done!
