where would one find the Fskcw calling freq for 20m? -- regards, Bryan, N0LUF

can the 47v zeiner diode protection be applied to the qcx variants? -- regards, Bryan, N0LUF

Alex, Did you report the bias as 3.4 ma correctly?? I thought it was 30 ma.? I suggest a factory reset as the starting point. 73 Evan AC9TU

Hi all, Many thanks for your comments, which helped me to move forwards. There was a connection issue with the 5V SMPS because the connector was not quite straight. I resolved that, but when fiddling

For no output on a particular band, the typical culprit is no connectivity to one (or more) low pass toroids.? One way to fix this is knowing that you've trimmed the enameled leads of each toroid,

Hi Jason. For some reason RF Sweeps like you're seeing seem to happen often for folks. It just happened to me on newly built (Rev 2) High-Band QMX after getting some decent looking sweeps initially.

Hi Hans, I wish you can fully recover soon!! Take good care of you and your family!! Joan

I posted on this before. Do you have a Rev 1 QMX? It has a low power 1/2 watt zener diode rather than the 5 watt diode on rev 2 or 3. if the shorted D108 is your problem, indicted by a low resistance

Hi Ludwig, Cracked it. Following the links in the QDX manual got me the driver file, but I also needed the post mentioned in the QDX manual on how to install the driver on Win 7 as it wasn’t

Can you post a link to one that claims that for a TO-92 package? JZ

Various semiconductor data sheets explain the leads are the primary heat sink.

Jim “most of the heat is radiated from the leads ... socketed finals expose more lead than finals soldered” Would love an authoritative ?source for all this ^ (thin steel wire is a horrible

Jim and Jz, Thank you for some good explanations of why not the BS170. 73, -Franz, N3HFS

So, I bought a QMX kit at Hamvention last year. After assembly, I connected it and it blew up. As it turns out, mine had the short on the SMPS board. I ordered some new SMPS boards and powered it up

Thanks Ludwig, I did wonder if there was a driver needed. I’ll search the QDX manual. 73 Paul

That is a lot easier than the months it took me! But, I also sync every device on my network to better than .01s. Here were the instructions I

Not directly. since PCs / Laptops don't typically come with the hardware/software needed to read the serial data and the 1PPS pulse.The QMX obviously does and it works great with the GL2. A quick

Not without a lot of work. I have set up a Stratum 1 GPS tamed NTS server on a Pi. I am sure I would want to try it on windows. -- Colin - K6JTH http://tangokeys.com
