Hi Rich Can you direct me to that thread or post please? Thanks, Hans [email protected]> wrote:

Cool! Are you modifying the caps in band pass filter as noted in a previous thread? RichKQ9L

Woohoo! I will not sleep in this round :-) W.

I see on the http://shop.qrp-labs.com/kits/qdxrev2 link it has the following under "List of Features" i.e. 13V * 5W output at 9V supply (can be built for 4-5W at 12-13V supply) * Receive current

C1, C5 and C8 are all parallel and form a tank circuit with secondary 3 of T1. See page 14 of the latest classic QCX manual. Since the 30m build doesn't populate C8 you can easily add capacitance

I sent out a querie about adding 5 turns to T1 after it was installed and someone responded (maybe to my gmail account) about putting a cap across somewhere instead of winding the extra turns.? I now

Hi Brian, Thanks, that's an interesting idea. Does that mean some RF has been spotted leaking through Q5 in Tx anyway, I wonder? That would take the reactance at 14MHz from about 11 ohms up to about

And another one arrived in Norfolk, England this morning. TNT said it was due tomorrow! Bill M1BKF

No sign here Ian, ditto re receiving notification on Oct 26th. TNT website still says arriving Nov 2nd before 6pm. We'll see. The suspense is killing me lol. 73 Robbie M1ROK

Hi all I have managed to obtain sufficient parts to manufacture 375 more QDX kits which is less than I would like, but it is something to quench the thirst of the masses... at least for a little while

Click on the descriptive page for the QCX and you’ll be taken for the order page for the QCX+ with a base price that’s mere $6 more. The QCX has been discontinued. Same features as the QCX+ except

Hi Everyone, Just a quick note to say my QDX kit arrived, unmolested by the Revenue people, this morning. Stay safe, Steve G0XAR

QDX just arrived, not bad going, Notified on the 26th Oct just 4 working days. 73 Ian G4GIR

Correction cap C30 should of course be C1 (30pF). 73? Dave

Hi Dave, I assume that cap C30 is fully meshed but the circuit in not peaked.? My solution to this problem would be to install a small value capacitor in the C8 space, possibly 5 to 10pF (I'm not

Hi Julian, Just a passing thought. Have you experimented with C33? Earlier messages from some builders on this list refer to increased power output when C33 is reduced from 1 nF to about 150 pF. Good

You can still use the “cheap” connectors. After soldering on the wires and closing the connector up drip some epoxy or other sticky glue down inside the shield. When it sets up the inside will be

I hadn’t wound a toroid for a couple of years and was hesitant to get back in the game but finally started on a QCX Classic for 30 meters. The toroids went easy and now on tune up I need to add more

I missed that he had already changed C25 and C26.? I see it now.? Well then, I got nothin'.
