I would also verify the harmonic content, as a high distortion or harmonic emissions can also confuse a power meter. 73 Evan AC9TU

The 3.3 volt regulator measures 3.27 volts The 5 volt regulator measures 4.95 volts. Both are within spec, so not the issue. 73 Evan AC9TU

Dennis, I do not know how to figure out what to adjust based on the scan results.? I guess we will need a response from the designer as he should know. The scan is most definitely looking at the

John, There are many USB to TTL serial cables on the market that should allow you to control the mini from either a pc or RPi. Milt W8NUE

That's what I thought. It seemed to be stuck but meanwhile was transferred to Liege Airport, loaded onto a plane and transferred to the US, passed customs and then transferred within the US and

Rich, I checked that the QCX mini heats up my dummy load, but I need test equipment to confirm that it's working right. And the receiver appears to be working as well, so I don't think that hooking up

Greetings, Just a question about the display on the QCX Plus. I finished the 80 meter version last week. It's working fine with 4.2 watts (13 volts) I was noticing a few days ago the tuning rate

Wow! Without any prior update since October 31st, information this morning was still stating my package was stuck in Grace-Hollogne, I finally received my order today. Ok… at least everything is now

My ProgRock order has been stuck at Grace-Hollogne since Oct 29 (11 days) with no further updates. My previous order from QRP Labs only took a week to be delivered to Australia. Regards Ian

That reading will also be influenced by the SWR of your antenna. What is the reading while radiating into a dummy load? -- John AE5X https://ae5x.blogspot.com

Evan You were right on with the power setting. I had set it up on 40 but it was still down at mid-level on the other bands. I was sure that I had set them all. I found something unexpected about

Are you sure it’s not an alignment issue? I don’t hear any 700 Hz tone on my QCX Mini with headphones, earphones or powered speaker. It’s just a quiet hiss. I get some noise when I use a

Evan, Oh this is interesting.? You made me look closer at the schematic.? I don't think it's quite that the RF sweep has anything to do with the transmitter circuitry.? If you look, CLK2 from the

I saw mention made of MFSK as a mode and I wonder how many realize MFSK can be used to send images. Yes, images! I've been a fan of Kim Elliott's (KD9XB) program carried over shortwave, "Shortwave

My guess is that the MFJ is being ‘a bit’ generous. The only way to be really sure is to measure with a scope or a known-calibrated (at the frequency of interest) meter. Mike WM4B Sent: Monday,

Just wondering if anyone else is getting 9W or thereabouts on 80M with 12.2V and drawing 970mA and I have the 3:2 windings.? That is way higher than the graph on page 4 of the manual.? After tuning

I have just finished building it inc. The polyphase module Now got to link all the bits together and test it Peter M0PWX M0PWX Grabber Page (qsl.net)<https://www.qsl.net/m0pwx/grabbers.htm> Sent: 08

Suat, The RF sweep is measuring the total response that includes the transmitter/receiver LPF.? I would contend that most, if not all are the measurement is the response of the LPF.? The bandpass

Yes, and the signal is injected through a 100k resistor (ok, well, it has a fraction of a pF parallel capacitance too https://www.vishay.com/docs/60107/freqresp.pdf) so it will act as a "current

Fred, Fred, At first, I did think that the TX line out of the STM32 was at fault and reported the symptoms in the other thread.? After Hans posted the way that the PTT actually works I went back and
