Hi Mike, I think you should make new windings. Secondaries have to be made very tight and turn by turn. You have to get maximum possible space between the primary and secondary in the total length of

No, it is fundamentally a matter of matching phase and amplitude after the mixer. All components are SM and fixed. Hans has said one day it may be automatic, otherwise you need to be a dedicated

Should I try to get it better, and if so, how/what should I try to modify (BPF + LPF)? Thanks!

What is the exact name of the firmware file, including the extension, that you are copying onto the mass storage device? -- Compton VK2HRX Sydney, Australia

Hello Brian If it shows up as a mass storage device that means it is in firmware update mode. In that case it won't connect with PuTTY, until you copy in the firmware. My apologies if I missed

Glad I could help. It was a good exercise for me, as well. --John WB5YOO

Mike, the fact that your "after" SWR gets worse at lower frequency suggest to me that something probably broke or made an unwanted connection in the process.

Thank you John! I've tested everything and it looks good so I will proceed.

Paul XE2ITY has been on 60m I think continuously for quite a while. A quick search on all bands finds no other. 73 Alan G4ZFQ

Looking at the receiver board schematic, if T401 is on the board, you should see DC continuity from pin 7 on IC402 to pins 7 and 9 on IC403. The time to do a DC continuity check on a trifilar winding

In previous episodes of this saga - * L401 has a habit of producing a null in the 20m band if you wind it wrong * I wound it wrong * For giggles, I deleted it from my QMX. Suffered no ill effects,

You're good, for 1 & 2-- The windings of T401 and T507 do connect together on their respective component. Paul -- AI7JR

I'm still mid-build on the QMX.? I have the same symptom showing up - being a short circuit between the center of the BNC and the ground / outer shell.? Just checked it by accident, and drew some

I have continuity between the left A, B, C, and pin 7 as noted in the instructions. The right A, B, and C, share some continuity with the left. Is this correct? I expected these would be independent.

It is a good question OM and it has been discussed here more than once.... It doesn't actually work atm. AND it is on the "to be fixed soon" list. es vy 73 de "baab" w9ya

Eric, Strongly recommend you upgrade to the latest firmware c1.03d as the one you have looks very early. There have been a few upgrades due to dates not setting properly over the years since it was

hi there, Sometimes I do wspr to see the propagation, but not as often as I would like, from DL52ud Cabo San Lucas BCS regards!! XE2IF ________________________________ De: [email protected]

Hans: Any chance it will come out in the future in a QMX + (Plus) form-factor.? I'd rather build a less tight multi-bander. 73 Mark

I just finished my QMX build, and almost everything is working, except the CW sidetone level. When I go to the menu item concerning Sidetone level, the numbers and cursor all works, but the sidetone
