Here's how QDX's QSOs look in the W4MAI ( SK 2006 ) Memorial Sun room monitoring station. 72, Bill, N4QA.

Yeah so really it's all my fault for living in the furthest outer reaches of outer nowhere. But at least it's sunny, man. 73 Hans G0UPL http://qrp-labs.com https://www.buymeacoffee.com/g0upl >

Status Update:? I tried everything I could think of to get the display working but got nowhere. I finished the second QMX kit and all seemed to be working as expected. Swapping display boards between

I was right.? Package in Istanbul at 22:13 local on 18th July and in my hands in central England at 11:18 today, 19th.? When FedEx/TNT finally get their hands on the goods, they shift things

This morning, the modified QCX-17 is testing on the Magic Band at 50001.7 KHz CW whilst the QDX is looking for FT8 Qs on 14074.8 KHz. 72, Bill, N4QA

It depends.If you examine manufacturer's specifications for ferrite and powdered iron toroids, cores etc you willfind an item labeled "Curie Temepature". This is an upper limit at which the core

For anyone with the low band version of the qdx, what are the firmware band configuration settings?? The operating manual has the configuration for the high band version.? I'm curious about the

I think what OP Larry meant to say was that he reheated all the solder joints for the toroid leads, removing enamel insulation from the wire. He goes on to say that he had tested the connections

Hi all Firmware 1_10 is now available for download at http://qrp-labs.com/qdx Changes: - Faster rendering of the Configuration screen - Added "Custom USB name" parameter to Configuration screen -

I am Glad to have that Multiband QCX still working. DK3UM Hajo did all the work but there is no Hans like documentation on the work. see

Kees, there is also an interesting doc from Reiner about his multiband QCX+ with the schematics. Maybe this helps.

Hello, The sidetone of the Dits have this clacking sound, but only on the first dith (of the series of diths), please see the video. The problem also occurs when the QCX mini is in practice mode.

Timothy, You're not out of touch. This is just one of those electrophysical effects that happens to be that way. Ferrite and powdered iron cores, regardless of their shape, can take a good deal of

Doesn't the inductance go back to normal after the toroidcores? cool down. ??? I've never heard of this concept before.? I must be out off touch.

AS a retired field engineer, I can tell you that in the end the old cut an try school of circuit design is what makes all the sales boys and lab boy look good in the end. [email protected]>

Thank you Hans!!! I will add Elsie to my toolbelt. What prototyping method do you use? I find it takes so long to get something thrown together. I cut my copper clad by scoring it on both sides and

I repaired one QCX with a loud tone and it was a mis-wound Rx transformer- can't remember the number, but the one with 4 windings. -- 73, Dan? NM3A

Jim, I think the stable version of the T41 is pretty far off. I hope the QMX f/w is a lot sooner. -- 73, Dan? NM3A

Mine and probably many others are passing thru Paris currently. ?Next stop is probably Memphis. Aug AG5AT

Chris, Thanks for responding. The purpose of the request was to see if anything could be done with the "pile" of QCX-Mini's I have around here to make them more useful for WSPR and FT-8. With nearly
