EA4HVG All Messages By This Member #145237 Thanks, Mustafa! Looks pretty good!!!! It is only for 12v QMX+, right? I wish it had in the board a small buck converter board for 9v QMX+ ;) I am using a LM2596 based dc-dc step down converter, set to 9,5v, on my 9v QMX and QMX+ and they work great! No noise at all from the converter, although it is out side the case... maybe sticking a buck converter inside the QMX+ case generates a lot of noise...? Best regards and thanks for sharing the nice project 73! ? ? ?
[email protected] All Messages By This Member #145256 Thanks, yes it is only for 12V version. I didn't add a buck converter to prevent noise and linear regulator to prevent unefficiency. Maybe RF shielding effect from case prevents noise in your application. ? Thank you for your kind words. Mustafa Necati TA7MNA, 73
Glen Jenkins WB4KTF All Messages By This Member #145269 Hello Hans, I communicate with Mustafa about purchasing a few of his assemblies.? He has not figured out how to sell/get paid for his creation.? Can you please assist him or possibly add these into your For Sale order page? -- 73s, Glen, WB4KTF, Austin, TX

Actually, I’ve found a few payment options. There are three methods that I prefer not to mention here due to privacy reasons, but I’ve already received one payment and more are on the way. These methods may not be suitable for everyone, as they lack the convenience of PayPal. I’ve also figured out how to ship the packages reliably. While more convenient payment options would be better for customers, there are still viable alternatives available. I’m sorry to say that this business won’t last long — it’s a short-term project aimed at making the board more accessible worldwide. ? I will not ask for payments until new boards arrive. ? Regards, Necati TA7MNA, 73 ?
