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!

Yes do them separately, I did and it worked out fine. Jess AE0CW Sent from my iPhone

" Is there any reason why I cannot/should not do the windings separately following the wire winding pattern/sense in the diagram? Thank you for your guidance. Ron, AL7JR' > >

Hi All, Finally got around to change out the Q6 transistor, the initial one got toasted on initial setup. So now its an MPS751 as suggested. My qcx was from the initial batch. Weird problem that just

You probably could do it that way, but make sure you pay attention to the phase of the windings, as that is important in the circuit. Jack, W8TEE To: [email protected] Sent: Sunday, January 14, 2018

Dear Tim, Thanks for the message and information that your working on getting a QRSS signal on 630 Meters.?? So far, your the only reply I have got.? I did tune another receiver down to the WSPR

Dear Keith, The only cure for the drift problem that I see is using a GPS Stabilized 27 MHz Oscillator fed to the crystal terminals on the receiver board.?? A friend of mine is now building such a

I am new to building and having an extremely difficult time winding and installing T1 for the 40 meter kit. This has been my first effort at winding toroids. Between my eyesight and dexterity it's not

My QCX does the same thing. I found that I apparently sparked pin 19 (I think) of the micro controller. It is grounded internally and does that I have a new chip on the way. Barry NF1O

Gm Blue-tack and a heated solder sucker are the two must important tools I have. Cheers Paul M0pnn Sent: 14 January 2018 08:16 To: [email protected] Subject: Re: [QRPLabs] Soldering one pin headers
