I just received my QCX-40 (shipped from Missouri) and it was a rev 5 board.

I decided to buy another QCX-40. I live in the US. I ordered the radio on Jan 1. I downloaded REV-5 Manual Jan 7. I got a shipment notice the radio was shipped from the US on Jan 8. No shipping info nor any serial number given. Just that it was shipped from the US. I recently read QCX boards were out of stock and not expected to be available again until the middle of January. So that is what I know. My concern is which manual do I use to build the radio once it gets here? Will I get a Rev-4 or Rev-5 board? I would hate to think I need to throw away the Rev-5 manual and have to reprint 9 zillion pages for a Rev-4 manual for a radio I have not yet received. If I had known about all this, I would not have printed out the BIG Rev-5 manual and had it bound until I knew which manual to download. Personally I think communications are poor!

Damn Lee, take a pill.
Unless I missed something, Labs was on holiday vacation resulting in delay (announced in advance). HF Signals (uBitx) was on a back order with their new kit till mid January.
Either way, all assembly instructions will b the same. Enjoy the new toy!

I arrived late to the party, but...

...9 zillion pages...

That is a lot of pages to print. Still, if you prefer to print them out, that's your call.

I for one do not see having hard copy unreasonable.  Nor did I say you should not

Re: Which manual do I use?

George Korper
 

The important change is in the new firmware. The other changes are  much less significant. I print manuals but using the PDF in my smartphone is much easier to read
placement of components. My smartphone is actually my main radio and the QCX is a project, and very absorbing but shouldn't become a talisman. Neither should my smartphone. They are both gadgets and the process is learn ing. Not things. 

 MADAM,  please return my coat, I think I've had one too many radios.

It needs 5V fed up the coax. The shack end of the coax is attached to a home made antenna cut from PCB, with 5V fed to the coax inner side. It’s a bit rough, but does re-radiate the signal into the shack.

Re: QCX 50 Watt PA what is the max current for 50 watts.

ajparent1/KB1GMX
 

What in the spec made you assume that.  The manual is the arbiter as
its how to assemble the amp.  At 85ma bias you will get lower power as your
starting to depart from class C into class AB1 at lowered efficiency.

Typically the QCX (at 40m) will do 3-4W easily.  The 20M version a little less.

Playing with the attenuator is possible if your qcx is weak. Do try to not overdrive
the amp as you will get excess power and likely failures.  The attenuator as
explained in the manual does two things 3db (approximately 1/2) cut in power
and also insures the QCX sees a reasonable 50 ohm match.

Q: what current at 20V are you drawing at 45W out?  Stay under 4A
for longevity.  NOTE: if T3 is backward it is possible to force near 50W
but its inefficient and has increased heating.

Do check the number of turns on L4 and L3 as some require one less for
optimum power.

Re: Which manual do I use?

Some would say that you were being too hasty in not waiting until you received the kit but as yours has been shipped from the US you will get it quicker than if it had been shipped from Turkey, so small mercies etc!

You need to look at Section 10 Document Revision History, p145.

I really don't think you've got any reason to reprint the manual if you get a Rev 4 board. You will have an additional capacitor to install (C39) but that's all.

Re: Anyone have a dead QCX with a good receiver?

Andrea Massucco IZ1IVA
 

Nevermind, it's now stopped booting altogether.

I've first tried Hans' recommended fix (moving L5) but that didn't work, then snapped one leg of L5 without having a spare one. After much cursing I hoped G3JRH's fix could save the day (I have a small supply of Schottky diodes), but no.

Either my QCX is haunted or my solder is ageing causing issues around the circuits. I really can't think of other plausible reasons for these behaviour and I'm starting to think it'll be far easier for me to assemble a new QCX than troubleshooting this one.
