Is it possible to mute a group subscriber as these pseudo-QSLs are of no interest to me. Yes, I know I can mute a thread but the thread title keeps changing. 73, Andy

Jeff, Congratulations on the build! At this point it looks quite good. Leave as is and enjoy! Good luck on the portable ops. You're gonna have fun! =Don=

Just another example from the Sun room. 72, Bill, N4QA

Still somewhat a noob when it comes to adjusting filters and such but after doing the 20m "#2" modification and loading FW: 1.00.005 I swept the filters through the terminal. 20 meters looks great but

Yes Ron. It is a great tool for dodging QRM or spurious signals ("birdies"). 73, Don

FB, John.? Glad you are back operational, at least partially. I dodge lightening here also, but probably not as much as Costa Rica. All the best to you es yours.

All good Randy. Thank you.?Now just dodging the lightning. Lost balun on AV-680 last week to near strike. Now only 2 bands while waiting for a back-ordered replacement, JohnTI4JWC

Well…I clumsily destroyed this item, clipping a pin off, while modifying to fit location R17. Anyone have a spare or can suggest a source for ordering? Thanks Bob K4WRH

After operating with no problems for about a week, my QDX transceiver failed in the middle of an FT8 contact and the red light went out. When power is applied now, the red light comes on and then dims

Hello It isn't an anti-bounce capacitor. I don't believe in hardware anti-bounce in a system with a microcontroller, where such a thing can easily be done better in code. The 1nF capacitor is there

Hi, you need C218 in. It is a paddle contacts blocking anti-bouncing capacitor. So, yes I recomend you replace it. There is no additional parameter besides the dimension. 73 Bojan S53DZ

Any 0603 1nf 50V Ceramic capacitor would do. Or leave it, from a look at the circuit this is on one of the key inputs which doubles up as the microphone input. It probably won't be needed unless you

Hi, I have made QDX M a dual band transceiver. I have just chosen the 10m LPF and adjusted BPF to serve both frequencies. Works well. A bit more sensitive rx, about the same tx output power. 73 Bojan

Bertil, Plug in the USB. Then connect power to the QDX Does it show the fault message? Do you see the QDX audio device? 73 Alan G4ZFQ

I get the error message unknown USB device cod 43 on my win 11 computer. Also tried on a win 10 computer but same error. Also tried on a win 8 laptop where I downloaded the recommended driver in the

Hi all, I unfortunately chipped open C218 on my QMX board during assembly. Could someone please link to a suitable replacement part on Digikey? I understand it's a simple 0603 SMD 1nF cap, but not
