Hi, if you measure it outside the board it is fault. If you measure it on-board there should be connection between oll three. Please, see the schematics. 73 Bojan S53DZ

Yes, normal. Look at the schematic. They are all connected. -mike/w1mt

I do apologize for all of the questions I am asking today. I do have another, though. I ran a continuity check on each of the legs of the trifiliar transformer and they all test good. However, I get

Wayne, I have a different radio set up with Windows 10, but I know that the OS sound settings can be very squirrelly.? Look for "Sound" app.? When you plug in your QDX you should be able to see the

In order to make room for L508, D508 is installed with the body on the left side, with the stripe facing down, which is different than any of the other diodes. There is a blurb in the text that

I had a similar (maybe lightning) problem with a QCX+5W.? ?In that case I replaced the Si 5351 A-B-G? several times as well as the QCX demodulator chip (you don't have)? without getting it

Wayne. It tests the BPFs. Unless your LPFs are very bad they will make no noticeable difference. 73 Alan G4ZFQ

Looking at the photo on page 24 of QMX manual h, I think maybe diode D508 may be pictured in the wrong orientation.

Either Meinberg or Dimension 4 will work well for Windows systems, and I highly recommend the use of either one instead of the built-in Windows time sync, which frankly sucks. For Linux folks,

My main ham system is a Pi-400. Works great and no funny issues like Windows. I don't know if you've run fldigi etc. on Linux before, but this HowTo is a very helpful guide to the building and usage

Thanks. I'm sure there is one, as well. I'd say this is causing me to pull my hair out, but I'm already bald...HIHI. I may try running this on a pi to see if I get better results. Wayne

I've been following the thread on your audio issue. Very strange as obviously the sound card is working and Windows sees it. I'm not a Windows guy, just have a test setup with Win10. Anyway I'm

DanI have the coffee can version of T-Mobile Home Internet Cellular Modem andrun Meinberg NTP on my machines when using T-Mobile. Thus far, NTP hasbeen golden.? Using Windows NTP services however is

Awesome. Thanks for the response. I ran RF filter sweeps on all of the bands to see if maybe something was wrong with my LPFs (assuming that's what this tests). All part of my still troubleshooting my

Yes, it's actually quite good for 80M. Better than mine. 73, Cliff, AE5ZA

Ronan, I was the guy that posted the limiter circuit back when. Here is a link to it: http://www.nd6t.com/qrp/speaker.htm ( http://www.nd6t.com/qrp/speaker.htm ) No, it does not distort until levels

This is the band sweep of 80M on my QDX. I'm wondering if this is normal:

What do the RF Plots look like? -mike/w1mt

The way I deal with this is to name my supplies with the actual voltages, e.g., +5V, +3.3V, etc. If there are analog and digital supplies at the same voltage, I use +3.3V_A, +3.3V_D. There’s

I saw that. Similar things were tried with the QCX and do work up to a point but they're not a proper solution. I'd rather not have to bodge the hardware when the problem can be sorted out gracefully
