"Measuring Response-Times"...

Sadly they are 'Hogtied' until #47... ;)

ROFL!

My wife and my daughter asked me about this “Chinese spy balloon”, I told them “Don’t worry, they already use Tik-Tok to spy on you.” 73 de Robert, OE7OER Von: [email protected]

Extra style points for monitoring the power supply with a 'scope to catch any overshoot on turn on/off. 73, Don N2VGU

Actually it would be interesting to know why one of them did not need a trunks change, and not all of them. I have one on the bench that I have not put much more on it since I installed the schottly

Jim, I’ve tuned up several 20 meter QCXs and all but one required 2 less turns on L3. But it’s always easier to remove turns than to add them so keep That in mind. 73… Ron [email protected]>

With it in the condition you mention where it’s generating what sounds like the 700 Hz test tone even though you aren’t in that test mode, it would be best to use a scope and see which stage is

I'm building my third QCX+, this one for 20 meters. Getting close to the point where I wind L3. On my 30 meter unit I had to clip a lead, remove two turns, and re-solder the coil to the board. As Hans

Factory resetting didn't help. What would I be looking for in terms of oscillation in the filter stages? Are we just talking about either a short between the input and output of one of the op-amps/a

I think the 58 mA without backlight was with the original Mini design using the low current opamps and the original voltage regulator. Some of those parts were changed and the current drain went up.

OK Jake, I think you may have an oscillation in one of the audio filter stages ... IC8A or B or IC9B. But first, since you see the different stuff every time you turn it on, I think it would be a good

Is that something to do with the PPS being for "the second I'm now telling you about on the serial interface, but which you haven't fully received yet"? 73, Willie N1JBJ

IC10 gives 5.8V on all pins except for 0V on pin 4 and 12V on pin 8. The volume is indeed very loud, it is only bearable to wear the earplugs in maybe the lowest 5% of the volume knob travel. Also,

Hi Al I have 2 QDX Ver 4.0 s (10 total) One that had the problem came with the QDX Ver 4, the other QDX Ver 4 came within the same shipment had no problem... The working BN43-202 was also from QRP

Peter, With the one I tested (and I do not think the QLG2s I now have are different) Galileo worked, my notes give restrictions of combinations. As Hans says, no. I *think* a proper backup battery

Don, my measurements (with a Fluke 179) are roughly the same as yours on my 40m QCX-mini on a 13.3V supply: about 86mA without backlight, 100mA with. Given that the manual shows draw of a (stock)

I dont think they are worrying about a balloon,? i think it is a distraction from something else john spendlove wrote on 2/4/2023 1:26 AM:
