GI0BIY and OK2BQN were the only ones to show up from this side of the pond and KN4OK still hoping to make it over the pond. Where are all the nicely build QRP Labs rigs ready to join in for some fun ?

as you have used the summer to build the rig, why not work on the antennas during the winter.? And maybe get on the air with the QMX+. Anyhow have fun :-) Martin DK3UW

What diodes and configuration?? Perhaps you pull more current than they can handle and thus have a voltage drop?

Have you externally measured the input voltage at the same time as looking at the QMX+ display? Also what does an external measurement show during transmit? 73, Cliff, AE5ZA

I will try that! 73, Andreas, K6AKW

Hello All, This is the first time joining a "group" so I am likely going to have difficulties navigating this place for while. I had xtal go bad on my Atlas 210x and its proving to be a challenge to

Hi Dave I don't think 1W on 6m is normal; are you confident of your power measurement? For example here we use the David NM0S QRP-o-Meter and initially also read low power on 6m; until I read the

I went with 11 turns on both L510 and L513 as suggested by DH8WN and it brought up my 15M power considerably. 11 tight turns on L513 worked fine. /g/QRPLabs/message/118629 73 de

60m IS available in the US, but the channels make it rather useless too. So I second the effort to reprogram that slot. On the other hand, upgrading your license sounds like a pretty good idea! -- 73,

Just finished building my QMX Midband. Everything seems to be working fine except that the output on 15m is 3dB below that on the other bands. Here is output power by band and by voltage: The scans

Got my QMX+ up and running today. The unit is configured for 12 volt operation and I have made sure that my input voltage is 12 volts or less. My battery has a nominal voltage other than 12 volts, so

so far I get - correct BAT_LEVEL value - PWR_ON pulled down when left encoder depressed no 3.3 volts present at ?LIN_REG_EN when depressing the left rotary encoder the voltage at LIN_REG_EN goes to

Thanks Hans. One other note of possible interest. When Message 2 completes, it immediately begins Message 1 with the digit "8", then sends Message 1, which in my case is my call: N7RCS. All my other

Ludwig, Thank you for the guidance & fast response! I'm going to give this a shot tonight. Best regards! ~G

Sorry, figured it out: I was in practice mode in CW, thus the P and no RF output. 73, Andreas, K6AKW

Gorden, in this document ( /g/QRPLabs/wiki/36878 ) from QRP Labs Wiki you find a description of the switch on process, about the levels of some signals and also a link to a sketch to

Does anybody know what the P at the end of the second line means? 73, Andreas, K6AKW

The 60m band is not available in VK so similar "waste" here. Replacing it with 80m would work, receiver performance should be ok. But you would need to check the LPF as it may not have enough harmonic

Why not go for a license upgrade? <samcollins910@...> wrote:
