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

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

Mike I use a 12v 7AH battery from our own domestic alarm system.? It sits in a box on my desk, charged by a small solar panel, and feeds my QCX family and my FT817.? As you say, the security company

This is just an antenna switch. You supply a RX and panoramic display yourself. 73 Alan G4ZFQ

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

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.

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.

Thanks Paul I agree, and I have amended the manual accordingly. 73 Hans G0UPL http://qrp-labs.com

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

Hi George Yes, you are correct... T2 is a very important component. I like to wind my toroids as neatly and tightly as possible because it actually does increase the Q and that improves the

Hello Hew I was a bit mystified by that... so had to look into it... I do not think you received your QDX. I think you received order 50607 which was two QLG2-SE kits. 50063 does not appear to have

I tried the 1300 and 1900 slots on 40m with no success. My cq calls did not register on the RBN network. Also my qcx mini rx decoder does not seem to work, I just get random letters even though I can

May I suggest also checking that the CAT polling interval is 10 seconds. Rapid polling is not necessary on QDX because there is no way for the QDX to change its frequency by itself. Polling is only

Hi Earl, I have noticed an issue with wsjt-x that no tx audio tones are produced from the pc to feed the tx on the first transmission or after a band change. Your QDX may not be the problem. I have

Love the radio looking forward to the build. My order number is?#50374 so still have a few days to go I imagine and shipping from Turkey to South Africa will also take some time so will be patient. I

Hello all Got my new kit up and working yesterday.? Still a whole lot to learn and a whole lot of manual to read. I am using a Raspberry pi 4 as the computer with the "Build a pi" software suite.?

I still keep a good old sealed Lead Acid AGM cell on the bench, both a 5 AH and a 12AH. They are cheap easy to charge and take a bunch of abuse. Not that I abuse them. I can leave them on the float

Hello, This is a very important step. Hans has advised *extreme care*. I suggest following Han's method to a "T'. Looking over my workmanship in the 50 watt amp. I see I didn't take this seriously

Yes they are, and absolutely he will. I might able to help, and will email you privately. -- Julian, N4JO.
