Daniel, Without the SMPS boards, I measure a resistance of only 250 ohms on the mainboard between PWR_HOLD and GND. PWR_HOLD is connected only to pin 53 of the processor. I therefore conclude that

Hello, Yesterday I make a QSO with the internal mic. I see we need another external mic. But it's possible to remove internal mic (I mean "desolder"), but install another good mic at this same

Paul, NA5N, has a good summary here. https://www.rmham.org/wp-content/uploads/2023/03/4_NA5N_Solar-Propagation-Companion.pdf

Joerg, No, that doesn't sound good, but as long as the main processor is good, it's worth fixing. If you can identify the failures. It looks as if the failure on the 5V PS took out the 3.3 V supply

My dummy load uses 4 x 51R 2W SMD resistors connected in series parallel, then 2k5 to 2 x 100R to give a dummy load come 40dB attenuator.? It also has a BAT41 Schottky diode and 0.1 uF capacitor to

Hi, I'm using a gaming headset with build in mic. I found that the mic wasn't sensitive enough as I had to set the mic gain on my QMX so high that it started to produce undesirable background

Hello all, My best bet is that the 50 ohm SMA load has already been overheated, changing the value of the terminating resistor, which is the cause of the 1:1.5 SWR after all. 73, Roelof, pa0rdt

Thank you all - this is sound advice. I own a dummy load, but am in a different QTH so I used what I had at hand. [email protected]> wrote:

I hadn't thought of using a headset...I have a BM10ic that would probably work pretty well so I shall collect bits for an appropriate adaptor!

to explain, i remember formerly my both `normal? QMX i programmed the messages by the rig directly, PUTTY i?m using only since i have the QMX+ ... that?s why i stumbled about? ;) vy 73 Udo DF4BJ

Many thanks.

Thanks a lot to everyone for your helpful tips. I've now removed the two SMPS boards and measured on the mainboard. The resistance between PWR_HOLD and GND is only 250 ohms. Between VDD and GND, it's

Hi There was a change in 1_01_003 <https://qrp-labs.com/images/qmx/ssb/firmware/1_01_003.zip> which prevented accidental VOX activation when pressing any buttons, by activating a timer that ignored

Bonjour Benjamin, Je me permets ce lien qui donne des explications assez claires et simples sur les paramètres de propag Au plaisir 73 -- Jean-Jacques - F5IJO FISTS#17008 LICW#5902

GM Ed, a Little off topic but could you point me some document about solar conditions on how to interpret this : Conditions were OK. SSN = 108, SFI = 156, A = 14, K = 5. Many Thanks 73, Ben ON5BGO
