Thank you Eike. Right now I'm just using one channel (tip) and the other one is left open, unterminated. " If the signal on both tip and ring are actually mono and always in phase then this whole

OK Chris. I was confused because in your previous reply, you said you had disabled SWR protection. Thanks for clarifying. Tony [email protected]> wrote:

I have unsoltdered the output of IC101 from the PCB and while testing, it now shows 3.3V when power on is pushed. Current draw is 0 amp. So, problem with a short is further the

This is a mono powered speaker... as I mentioned... " Which output do I use? Tip? Ring? one left open? both tied together? "

I use my QMX with an Anker soundcore mini. Stereo cable on both ends and it works well. There's one data point for you... 72 de va3rr

I just received my QMX+ today. I built a QCX+ previously but this time I wanted the QMX+ to come pre-assembled. So far, I just did some quick tests, receive, transmit, changed a few

Tony: I set my SWR protection to 3:1 so the last set of data would not change.

Granted I have only been using this radio two days (and am really enjoying it), but I can't for the life of me figure out how one cascades filters together.? ?In principle it is very clear what the

Eric, Bandwidth? You mean tuning range? The divide by 4 is easier as it is there. It will give you a lower minimum than using the 2 outputs unless you can enable a quadrature output below 3.5MHz.

I'm interested in doing some SDR tinkering, using the receiver module kit and the VFO kit.? The LO input on the receiver module is divided down by 4 to make the quadrature clocks for the Tayloe

I recently purchased a pound of Kester 63/37 1.1% 245 in .031 dia for general use.? Does anyone have experience or comments on this solder?? My original supply of Kester 63/37 rosin core is getting

Barry What you described is exactly what should have happened, at least on a Windows PC. Adjusting the potentiometer should bring up the display or a line of black squares, too much

Quick check to try. QMX+off. USB cable connected to PC/MAC from QMX+. Push top encoder button once to power on. Check to see if PC/MAC now sees the QMX as a USB device. If so, start a terminal program

Barry, I feel your pain!! Please scroll down and read through the thread “New Build but can’t get firmware to load” there could be ANY number of possible issues but you can see exactly what I

Chris, Can you please rerun your tests with SWR protection turned on? I think this would give us a more realistic view of the conditions the BS170s are experiencing in actual
