Re: AA Battery Power for QRP Labs gear
Yes, that would be a great idea, but many hams are collectors who get very emotionally attached to their stuff, which keeps resale value absurdly high, keeping such equipment out of reach of

Re: A remote QDX....
How about a Raspberry Pi/Power over Ethernet ("PoE") solution? That would be the Cat's Meow... One of my future projects is a multi-channel Ethernet connected GUI for QCXs, so I can run my growing

Re: A remote QDX....
Peter, You¡¯ve hit on a brilliant idea, one that could be expanded still further. Technically, anything that could be handled over an Ethernet cable could probably be handled over the Internet or

Re: QDX TRIFILAR STEP 2.12 Wind and install trifilar toroid T2
I don't think the draft manual is quite clear enough on this.? It is important that the START and FINISH of the windings are identified as well as just continuity.? It would be possible to mix up

A remote QDX....
While lying in bed recently, my mind pondered on the QDX and it suddenly struck me that it has no manual controls at all: it is totally controlled by software. This would make it ideal for remote

Hee Hee...can you imagine wrapping? in such a way that one wire gets wrapped around the the other or others in such a manner, at the end of say 10 inches it is close to an inch longer than the other

Re: AA Battery Power for QRP Labs gear
Yeah, I¡¯m still sorry I didn¡¯t pick up several of those fire-alarm batteries at my local ReStore when they were only $1 each, they¡¯d be perfect for the QCX I have on order. Recycling is to raw

Re: QDX shipping update
I received my shipping notice email (from US stock) for order 50001 this morning. So in a week or so I should get the QDX. Maybe I will be able to build over Thanksgiving... We will see. Fred W0FMS/7

Those looking to save money might contact local companies that service fire alarms and exit lights for public spaces. They typically have to replace the batteries, typically small, sealed, lead-acid

Syd, I just finished a QCX+ (40M) build. I had to remove 7 turns from T1 to get the trimmer capacitor off the fully open position. The BPF (8.7) moved up as I removed turns. I did not bother going

Re: Panadaptor
Hi Paul Nice idea. But then the QCX-mini is by far the smallest part of the whole setup. Can you imagine having a panadapter as a separate box the size of QCX mini? Like Elecraft's KX3 + PX3 combo.

Panadaptor
This panadaptor looks perfect as an addition to the qcx mini etc. A description can be seen here:?https://youtu.be/jKqXBvsrGsI And can be purchased on Banggood.com at the moment for around 40 euros.

Re: QDX manual update
On page 17, the text describes the 3:3 option for T1 but the board diagram still references the 3:2 option. This might be slightly confusing. Also, maybe there should be a pointer on this page back to
