Excellent, ?Jim. ?T-1 is a pain to wind - it took me two tries to get it right Enjoy the rig — you will be amazed how far 5 Watts can travel. My best DX is Poland — about 4300 Miles. -- 73,

Could it be that the display is shorting against the filter toroid? That is a known issue with the QCX. 73 de Frank PA3CNO

Hi Al, I traced a 'distortion' problem to something no one has talked about on this group [yet?]. When the receiver was receiving audio and thus drawing slightly more current. That load on the

My QCX is in the QRP Labs metal case.? I am using iPhone headphones.? The sidetone I hear has fuzz/distortion but when I put my left hand on the case the fuzz/distortion goes away (using right hand

You’re partly right. And I do sincerely apologize for the snarky part about “kidding!”. For what it’s worth, it doesn’t make me feel better to “put down” someone. I simply found the

Chris, Check the placement of you LCD. Sometimes the holding flanges will touch one of the output coils (right hand corner) and the RF will cause the screen to go flaky or blank. But first try a real

Thank you Al for sharing this helpful information.? 73, John AA7US

It always makes one feel big knowing something that the next guy hasn't a clue about, but seriously, this is a kit that is targeted at children and beginners to the hobby. Do you think that instead of

You'd think so, but it's basically the same as any other monoband dipole.? Every dipole has a design frequency, but usually they're broadband enough to cover most of the band with an acceptable

Hello, I have the same effect on my QCX. In SEMI mode, a weak signal is sent between the characters. Reducing R41 reduces it a bit, but it persists. At the drain of BS170 there is a stable voltage? (

I think you misunderstand me.? I don't want to tune to one band, I really did mean one *frequency* , hopefully the sole 20m FT8 one shortly after Hans issues the U3S firmware upgrade.? I have no

There's a lot to be said for using monoband dipoles, but they also have their downsides. Say we hike to the top of a mountain with a dipole for our favorite band and find that band is mostly dead. It

Sorry about my poor math, guys. 50 / 3 = 17 Ohms, (not 33). 17 Ohms is definitely below the sweet spot of most antenna matchboxes. ?- Rick

I built my QLG1 GPS module about 1? years ago. Lately, I’ve been noticing when first powered up it seems to take a long time to acquire the satellites and produce the 1 PPS. I use it with a U3S and

A 9V battery will not power the QCX.in Tx mode. ? Yes you can use a 12V motorcycle battery just fine.? For all power sources a 1A to 1.5 A fuse is a good idea although with any adequate power source

Crazy! That chap does not have the fun of experimenting to see what can be done on a tiny plot. But he does have the capability of deceiving us that our bits of wire work well:-) 73 Alan G4ZFQ

This guy picked me up a few minutes ago: https://youtu.be/IBChwkjzliw Shouldn't present any problem!

Even more interesting was: *WHEN SHOULD YOU USE A MATCHBOX ?* *ANSWER: ?Hopefully Never! ?. . . because ALL matchboxes add unwanted losses!* ...and your following points which were sort of my

The only "standard" 9V battery I know is totally inadequate to supply the transmit current of a QCX. Yes a motorcycle battery will. Use a maximum 1 Amp fuse, it is also capable of doing much damage if
