Re: #qmx IQ Sweep ? #qmx
Hi Chris How do you mean, the "saturation of peaks"?? To me that sweep looks normal, healthy. 73 Hans G0UPL http://qrp-labs.com https://buymeacoffee.com/g0upl [email protected]> wrote:

It seems spongy like it's forcing the dit and dah spacing if that makes sense.

#qmx IQ Sweep ? #qmx
Any thoughts on the saturation of peaks? I am seeing similar plots on multiple QMXs. Firmware issue or Putty issue?

Re: QCX mini with straight key
I'm not sure what you mean. There is a setting in the keyer menu for straight key. The cadence is established by the movement of your wrist and finger. -- 73, Dan - W2DLC

QCX mini with straight key
I tried using my Navy Flame Proof key with a QCX-Mini last night and noticed that it was keeping the cadence slow, I don't know how to describe it, but when I tried to key fast it felt slow. Is there

No, but there were a few times the SWR protection triggered while tuning a random wire that starts a foot a way or so.

Re: 10w HF Linear PA current consumption does not change after installation #10W_PA
Timmy, Who cares. That amp from Diz is rather nice but does not work at all well on 15 or 10M. So stay on topic and help the gentleman with his QRPL 10W amp. -- Allison ------------------ Post

Re: 10w HF Linear PA current consumption does not change after installation #10W_PA
First you need to put a load on it for safety. Ground the TX enable line or the bias setting will not happen. The TX line is so the amp can be shut down for RX. -- Allison ------------------ Post

David, Sorry, it should read “in the range 1400-1600Hz”. John G4YTJ

Re: QMX WSPR fault
Hi David, With earlier QRP Labs you had to set a frequency of the official dial frequency plus 1500 Hz plus or minus 100Hz. This is because a conventional SSB Tx would take a tone in the range 1400 -

Make sure that the enamel? is completely removed in the areas where you are going to solder. If the holes they are going into are plated through holes? ie PTH then as a temp measure you can use a

Re: 10w HF Linear PA current consumption does not change after installation #10W_PA
You write: When I start to turn one of the pots, it is still 140mA stable. That suggests to me that you expect the current to increase immediately at the start of the pot. It won't but at a certain
