I regard that as a potential deathtrap. ESD mats are cheap and far safer and will not ground you if you playing with line voltages or higher (tube gear). Also it has great potential to create a

A good ESD work surface is conductive, but not too conductive. ?That way it maintains equipotential between your work, your wrist strap, and your iron, but any inadvertent discharge that does occur

U3s was here in 9 days and the enclosure from china went thru customs as usual and arrived on day 16. No tariff issue. Not bad. -- regards, Bryan, N0LUF

That is an exceptional 3D printed enclosure. Would you mind describing your finishing and labeling procedures, as well as the type of filament used? Tnx & 73, -Lloyd (wa4efs) Sent: Monday,

Dan, did you find the issue to your culprit? Read Ronald Taylor’s recent thread about “QCX buttons stuck”. ?I replied to his thread too. ?I was having the same exact issue. ?It is indeed a

Awesome job!

Love it! -- 73, Dan - W2DLC

Perhaps posting a screenshot of the LPF scans and swr scans for 10m and 6m would give us some data to start with. Stan

Chris, you may need to update Hamlib. I did. There is a button on version 2.7 to do so, but I had to first install OpenSSL on my Windows 10 in order to update Hamlib using the button. TS-480 worked

Hi Ron, It is a relieve to read this post. ?The same exact thing is happening with my QCX mini 20m because I was not using the correct “exit button”. ?For some reason I would press the encoder

KUDOS. Looks like something I've seen ripped from an old jeep. I LIKE IT! 73, Paul KY4XJ

Okay, I went a little crazy being a military radio guy the standard QMX case just wasn't doing it for me.? So I decided to draw up a PRC-174/CMX+ clone using Fusion 360 CAD software and my 3D

All working well except 1 W on 10 m and 0.6 W on 6 m.? Already checked for correct winding and bad/insulated solder joints.? Anyone else have this problem or have suggestions to resolve.? Thanks in

Thanks. It does it with a known good power supply into a dummy load sometimes. Sometimes it works for a few minutes. It’s in a die cast box with a 0.1 uF across the power connector and the power

Jerry, thanks for the suggestions. I’ll give those a try. I am powering it with a battery and using a good dummy load so I can eliminate those issues. I like your idea of shorting out some of the

Stan, I’ll try attaching the images again in a few minutes, but I don’t think that will help. Even when I use my wife’s computer, I can still see the images so I think there may be a problem

After another look at the schematic, I see no reason to lift the RX_IN wire of L401 or the IC402-9 wire of T401.? Just shorting those wires to ground should be sufficient. RX_IN might see 12vdc

Matthew, your original screenshots of the IQ plots did not come through. Maybe if you show us the screenshots it will give us some ideas to help you with. And if "everything works fine", is there a

What kind of power supply are you using? Try running off a 9v transistor radio battery, or something else reasonably quiet. Do you have a 50 ohm dummy load at the antenna port when testing? I'd try
